text: On 21 October, the Northern Alliance led by General Dostum prepared to attack the fortified village of Bishqab. Dostum's forces were equipped with AK47s, light machine guns, and Rocket Propelled Grenade launchers (RPGs). The Northern Alliance totaled about 1,500 cavalry and 1,500 light infantry. They were assisted by the 12-member U.S. Special Forces team and American airpower. Bishqab was defended by several T-54/55 tanks, a number of BMPs (armored personnel carriers) armed with autocannons and machine guns, and several ZSU-23 anti-aircraft artillery, along with mortars, machine guns, RPGs, and mines. The armor and heavy weapons were usually manned by the foreign Taliban and Al-Qaeda fighters, who fought fiercely and did not surrender readily. To reach the enemy, Dostum's forces needed to cross a -wide open plain cut by seven ridges, each between high, and spaced about apart, that left the advancing forces completely exposed to enemy fire. To the U.S. Special Forces, it looked like "the Charge of the Light Brigade, Battle of Fredericksburg, and Pickett's Charge at Gettysburg all rolled into one". Supported by American air power and precision-guided munitions, the teams were able to call down accurate fires on the enemy; in one 18-hour battle, they destroyed over 20 armored and 20 support vehicles. Many of the Taliban threw away their weapons and ran, or made a secret pact with Dostum's forces to join his forces as soon as the attack began.

text: The next day, the Northern Alliance prepared to attack Cobaki. The U.S. Special Ops teams used SOFLAM Laser Target Designators to identify targets for air strikes on the enemy armor and artillery. The Northern Alliance followed this with a horse cavalry charge. When it looked like Dostum's cavalry charge would fail, several members of ODA 595 rode into action and helped win the battle. Within the first two weeks, ODA 595 was joined by two more special forces soldiers, bringing their number to 14. They split the team into four three-man teams and spread out over of mountainous terrain, in some cases 12 to 18 hours apart from each other by horseback. Each team of NCOs advised senior Northern Alliance commanders and called in airstrikes and resupply for their forces.


text: On 2 November, a third Special Forces team, ODA 534, was inserted by SOAR to assist Northern Alliance General Atta Mohammad. ODA 534 later linked up with the CIA team Jawbreaker, ODA 595 and 555, and General Dostum outside Mazar-i-Sharif.


text: One of the Task Force Dagger's primary strategic objectives was to capture Mazar-i-Sharif and an airfield so the U.S. could use it to bring in supplies and more troops. On about 6 November, the Northern Alliance broke through the Taliban defense in the valley of Darah Sof District, from Mazar-i-Sharif. The three teams reunited near Mazar-i-Sharif and participated in its capture. They guided hundreds of GPS-guided 2,000-pound JDAM precision-guided munitions dropped by USAF B-1B Lancer and B-52 Stratofortress heavy bombers onto Taliban and Al-Qaeda positions near Mazar-i-Sharif.


text: ODA 534 from Charlie Company, 1st Btn, 5th SFG was split between the Darya and Balkh Valleys supporting General Atta Mohammad.


text: ODA 553 from Bravo Company, 2nd Btn, 5th SFG was inserted on 2 November. The ten-man team in Bamyan supported General Karim Khalili and his militia in the northern regions of Afghanistan. Together the men worked to flush Taliban forces from the region with a number of cities quickly falling to Kahili's tribal forces.


text: ODA 555 ("Triple Nickel") from Bravo Company, 2nd Btn, 5th SFG was, with ODA 595, one of two ODA units inserted on 19 October. They supported General Shariff in the Panjshir Valley. It linked up with General Fahim Akhtar Khan in the Bagram/Kabul area of the Panjshir Valley, near the fortifications surrounding Bagram Air Base. Air Force Combat Controller Sgt. Calvin Markham used a SOFLAM Laser Target Designators to identify targets for airstrikes on the enemy armor and artillery. He set up a series of strikes on the fields of targets around the airbase, guiding wave after wave of precision-guided munitions onto tanks, armored personnel carriers, guns, and fortifications around Bagram.


text: ODA 555 worked closely with Northern Alliance forces under warlord Fahim Khan. They called in airstrikes that dropped 15,000-lb BLU-28 'Daisy Cutter' bombs on Taliban troop positions with devastating effect along the Shomali Plain. ODA 555 accompanied Khan's militia and fought alongside them in numerous engagements. They sometimes called in airstrikes danger close to stop Taliban attacks. They were with the Northern Alliance militia when they captured Mazar-i-Sharif on 9 and 10 November, and with the assistance of ODA 595 and Jawbreaker, accompanied the militia when they captured Kabul on 13 and 14 November.


text: ODA 574 ("Texas One-Two") from Alpha Company, 3rd Btn, 5th SFG deployed from K2 just outside of Tarin Kowt on 14 November, along with Pashtun militia leader, Hamid Karzai. As Karzai's forces pushed south towards Kandahar, an error by an attached USAF TACP resulted in a 2,000-lb GPS-guided JDAM hitting the ODA's position, killing and wounding several Special Forces and Afghan militiamen. Assisted by the remaining ODA 586 soldiers, with reinforcements from ODA 750 and ODA 524, Karzai was able to negotiate the surrender of Taliban forces around Kandahar and go on to become the first Afghan president.


text: ODA 583 from Bravo Company, 3rd Btn, 5th SFG deployed late on 21 November to the Shin Narai Valley supporting Gul Agha Sherzai near the Shin Narai Valley. During their infiltration, one of the helicopters experienced a mechanical failure and made an emergency landing. Another helicopter was dispatched but dropped the team in the wrong location. The 583 finally joined the CIA team and Sherzai and pushed towards Kandahar. The 583 set up observation posts overlooking Kandahar International Airport and over the next few days, called in ongoing air strikes on the Taliban positions. On 7 December, ODA 583 helped Sherzai's forces capture the airport and very soon the city of Kandahar.


text: ODA 585 from Bravo Company, 3rd Btn, 5th SFG inserted by helo on 23 October into Kunduz to support General Burilla Kahn. Despite initial missed air strikes that left Burillah unimpressed, 585's senior enlisted member Master Sergeant Bolduc called in another wave of F-18 strikes that in four passes obliterated several Taliban command bunkers and collapsed several sections of the enemy's trench lines. The display of coordinated airpower by 585 earned General Burillah's respect and proved their value to the Afghans. ODA 586 Eventually joined 585 and General Burillah's men for the final assault on the provincial city of Konduz, seizing it on 11 November.


text: ODA 586 from Bravo Company, 3rd Btn, 5th SFG was in Farkhar supporting General Daoud Khan in the Takhar province, who took the capital city of Taloqan on 11 November. Khan's troops, supported by airstrikes called in by 586, eventually took the city and provincial capital of Konduz on 26 November.


text: ODA 595 from Charlie Company, 3rd Btn, 5th SFG was with ODA 555 of two ODA units inserted on 19 October. They helped General Dostum outside Mazar-i-Sharif. ODA 595 were instrumental in helping the Northern Alliance to capture several thousand foreign and Afghan Taliban and bringing hundreds more local Afghans over to the Northern Alliance side. Over two months they destroyed several hundred enemy vehicles, liberated about 50 towns and six northern provinces comprising hundred square kilometers.


text: The well-placed ordnance dropped on the Taliban by the airpower controlled by Task Force Dagger forced the Taliban and Al-Qaeda forces to continually pull back. The rapidity with which the enemy resistance crumbled eliminated the U.S. military's plans to deploy significant conventional ground forces.


text: The Taliban and Al Qaeda forces were defeated within two months. It could have happened more quickly, but the Bush administration was fearful that without a provisional government to take over Kabul, the Northern Alliance would commit atrocities as they had when they had previously occupied the capital.


text: The ground forces who eventually entered Afghanistan were left to pursue high-value targets, including Osama bin Laden, among the Al-Qaeda near the Pakistani border. The high-level command of Task Force Dagger remained in the country until the unit was finally redeployed to the United States in April 2002.


text: Major Mark E. Mitchell of the 5th Special Forces Group (Airborne) was awarded the Distinguished Service Cross for gallantry in November 2001 at Qala-i-Jangi Fortress, Mazar-i-Sharif, Afghanistan.


text: During Operation Iraqi Freedom 5th SFG(A) assisted in the capture of Saddam Hussein and was deployed throughout Iraq as part of Combined Joint Special Operations Task Force – Arabian Peninsula (CJSOTF-AP). 5th Group teamed up with various National Guard support groups from many different states: Virginia, Texas, Louisiana, New York, Minnesota, Wisconsin and others.


text: During ten years of service in the Vietnam War, eighteen Special Forces soldiers were awarded the Medal of Honor, the nation's highest award for conspicuous gallantry and exceptional heroism under fire.

title: Galleon

text: Galleons were large, multi-decked sailing ships first used as armed cargo carriers by European states from the 16th to 18th centuries during the age of sail and were the principal vessels drafted for use as warships until the Anglo-Dutch Wars of the mid-1600s. Galleons generally carried three or more masts with a lateen fore-and-aft rig on the rear masts, were carvel built with a prominent squared off raised stern, and used square-rigged sail plans on their fore-mast and main-masts.


title: Galleon

text: Such ships were the mainstay of maritime commerce into the early 19th century, and were often drafted into use as auxiliary naval war vessels—indeed, were the mainstay of contending fleets through most of the 150 years of the Age of Exploration—before the Anglo-Dutch wars brought purpose-built ship-rigged warships, ships of the line, that thereafter dominated war at sea during the remainder of the age of sail.


title: Galleon

text: The word "galleon" 'large ship' comes from Old French "galion" 'armed ship of burden' or from (Castilian) Spanish "galeón" 'galleon, armed merchant ship', (perhaps via Italian "galeone" 'big "galea", big galley') from Medieval Greek "galea" 'galley', to which the French or Spanish augmentative suffix "-on" is added. Another possible origin is the Old French word "galie" 'galley'; also from Medieval Greek "galea". The "galea" was a warship of the Byzantine navy, and its name may be related to the Greek word "galeos" 'dogfish shark'. The term was originally given to certain types of war galleys in the Middle Ages.


title: Galleon

text: The "Annali Genovesi" mention galleons of 60, 64 and 80 oars, used for battle and on missions of exploration, in the 12th and 13th centuries. It is very likely that the "galleons" and "galliots" mentioned in the accounts of the crusades were the same vessels. In the early 16th century, the Venetian "galleoni" were a new class of galley used to hunt down pirates in the Mediterranean.


title: Galleon

text: Later, when the term started to be applied to sail-only vessels, it meant, like the English term "man-of-war", any large warship that was otherwise no different from the other sailing ships of the time.


title: Galleon

text: In the beginning of the 16th century, a lowering of the carrack's forecastle and elongation of the hull gave the ocean-going galleons an unprecedented level of stability in the water, and reduced wind resistance at the front, leading to a faster, more maneuverable vessel. The galleon differed from the older types primarily by being longer, lower and narrower, with a square tuck stern instead of a round tuck, and by having a snout or head projecting forward from the bows below the level of the forecastle. In Portugal at least, Portuguese carracks were usually very large ships for their time (often over 1,000 tons), while galleons were mostly under 500 tons, although the Manila galleons were to reach up to 2,000 tons. With the introduction of the galleon in Portuguese India Armadas during the first quarter of the 16th century, carracks' armament was reduced as they became almost exclusively cargo ships (which is why the Portuguese carracks were pushed to such large sizes), leaving any fighting to be done to the galleons. One of the largest and most famous of Portuguese galleons was the "São João Baptista" (nicknamed "Botafogo", "Spitfire"), a 1,000-ton galleon built in 1534, said to have carried 366 guns.


title: Galleon

text: Carracks also tended to be lightly armed and used for transporting cargo in all the fleets of other Western European states, while galleons were purpose-built warships, and were stronger, more heavily armed, and also cheaper to build (five galleons could cost around the same as three carracks) and were therefore a much better investment for use as warships or transports. There are disputes about its origins and development but each Atlantic sea power built types suited to its needs, while constantly learning from their rivals. It was the captains of the Spanish navy, Pedro Menéndez de Avilés and Álvaro de Bazán, who designed the definitive long and relatively narrow hulled galleon for Spain in the 1550s.


title: Galleon

text: The galleon was powered entirely by wind, using sails carried on three or four masts, with a lateen sail continuing to be used on the last (usually third and fourth) masts. They were used in both military and trade applications, most famously in the Spanish treasure fleet, and the Manila galleons. While carracks played the leading role in early global explorations, galleons also played a part in the 16th and 17th centuries. In fact, galleons were so versatile that a single vessel might be refitted for wartime and peacetime roles several times during its lifespan. The galleon was the prototype of all square-rigged ships with three or more masts for over two and a half centuries, including the later full-rigged ship.


title: Galleon

text: The principal warships of the opposing English and Spanish fleets in the 1588 confrontation of the Spanish Armada and in the 1589 confrontation of the English Armada were galleons, with the modified English race-built galleons developed by John Hawkins proving their great utility in combat, while the capacious Spanish galleons, designed primarily as transports, showed great endurance in the battles.


title: Galleon

text: Galleons were constructed from oak (for the keel), pine (for the masts) and various hardwoods for hull and decking. Hulls were usually carvel-built. The expenses involved in galleon construction were enormous. Hundreds of expert tradesmen (including carpenters, pitch-melters, blacksmiths, coopers, shipwrights, etc.) worked for months before a galleon was seaworthy. To cover the expense, galleons were often funded by groups of wealthy businessmen who pooled resources for a new ship. Therefore, most galleons were originally consigned for trade, although those captured by rival states were usually put into military service.


title: Galleon

text: The most common gun used aboard a galleon was the demi-culverin, although gun sizes up to demi-cannon were possible.


title: Galleon

text: Because of the long periods often spent at sea and poor conditions on board, many of the crew often perished during the voyage; therefore advanced rigging systems were developed so that the vessel could be sailed home by an active sailing crew a fraction of the size aboard at departure.


title: Galleon

text: Galleons were a class of blue-water sailing ship that combined the easy-to-maneuver fore-and-aft rig of smaller shipping (boats) with the square rig of late middle ages cargo vessels. The galleons solidified the place of the square-rig and the centrally situated tallest main-masts and the slightly shorter fore-masts of a square-rigged ship characteristic of the 16th–19th centuries, but introduced the use of the lateen rig to sail closer to the wind on a tack than could a square-rigged vessel—an important attribute in restricted waters, but more so over long voyages where holding a few compass points closer to the wind might save hundreds of miles and days or weeks of sailing 'beating into the wind'.


title: Galleon

text: The most distinguishing features of the galleon include the long, prominent beak or beakhead followed by a foremast and mainmast, both noticeably taller than the single or double lateen-rigged mizzenmasts with their sloped lateen-rig yards, and below those the square quarter gallery at the stern. On average with three masts, in larger galleons, a fourth mast was added, usually another lateen-rigged mizzen, called the bonaventure mizzen.


title: Galleon

text: The galleon continued to be used into the 18th century, by which time purpose-built vessels such as the fluyt, the brig and the full-rigged ship, both as a trading vessel and ship of the line, rendered it obsolete for trade and warfare respectively.


title: Galleon

text: The oldest known scale drawings in England are in a manuscript called "Fragments of Ancient Shipwrightry" made in about 1586 by Mathew Baker, a master-shipwright. This manuscript, held at the Pepysian Library, Magdalene College, Cambridge, provides an authentic reference for the size and shape of typical English galleons built during this period. Based on these plans, the Science Museum, London has built a 1:48 scale model ship that is an exemplar of galleons of this era.


title: Social psychology

text: Social psychology is the scientific study of how thoughts, feelings, and behaviors are influenced by the real or imagined presence of other people or by social norms. Social psychologists typically explain human behavior as a result of the relationship between mental states and social situations, studying the social conditions under which thoughts, feelings, and behaviors occur, and how these variables influence social interactions.


title: Social psychology

text: Although issues in social psychology have been discussed in philosophy for much of human history, the scientific discipline of social psychology formally began in the late 19th to early 20th century.


title: Social psychology

text: In the 19th century, social psychology began to emerge from the larger field of psychology. At the time, many psychologists were concerned with developing concrete explanations for the different aspects of human nature. They attempted to discover concrete cause-and-effect relationships that explained social interactions. In order to do so, they applied the scientific method to human behavior. The first published study in the field was Norman Triplett's 1898 experiment on the phenomenon of social facilitation. These psychological experiments later went on to form the foundation of much of 20th century social psychological findings.


title: Social psychology

text: During World War II, social psychologists were mostly concerned with studies of persuasion and propaganda for the U.S. military (see also psychological warfare). Following the war, researchers became interested in a variety of social problems, including issues of gender and racial prejudice. During the years immediately following World War II, there were frequent collaborations between psychologists and sociologists. The two disciplines, however, have become increasingly specialized and isolated from each other in recent years, with sociologists generally focusing on high-level, large-scale examinations of society, and psychologists generally focusing on more small-scale studies of individual human behaviors.


title: Social psychology

text: In the 1960s, there was growing interest in topics such as cognitive dissonance, bystander intervention, and aggression. In the 1970s, a number of conceptual challenges to social psychology emerged over issues such as ethical concerns about laboratory experimentation, whether attitudes could accurately predict behavior, and to what extent science could be done in a cultural context. It was also in this period where situationism—the theory that human behavior changes based on situational factors—emerged and challenged the relevance of self and personality in psychology.


title: Social psychology

text: By the 1980s and 1990s, social psychology had developed a number of solutions to these issues with regard to theory and methodology. At present, ethical standards regulate research, and pluralistic and multicultural perspectives to the social sciences have emerged. Most modern researchers in the 21st century are interested in phenomena such as attribution, social cognition, and self-concept. Social psychologists are, in addition, concerned with applied psychology, contributing towards applications of social psychology in health, education, law, and the workplace.


title: Social psychology

text: In social psychology, an attitude is a learned, global evaluation that influences thought and action. Attitudes are basic expressions of approval and disapproval or likes and dislikes. For example, enjoying chocolate ice cream or endorsing the values of a particular political party are examples of attitudes. Because people are influenced by multiple factors in any given situation, general attitudes are not always good predictors of specific behavior. For example, a person may generally value the environment but may not recycle a plastic bottle because of specific factors on a given day.


title: Social psychology

text: Research on attitudes has examined the distinction between traditional, self-reported attitudes and implicit, unconscious attitudes. Experiments using the Implicit Association Test (IAT), for instance, have found that people often demonstrate implicit bias against other races, even when their explicit responses profess impartiality. Likewise, one study found that in interracial interactions, explicit attitudes correlate with verbal behavior, while implicit attitudes correlate with nonverbal behavior.


title: Social psychology

text: Attitudes are also involved in several other areas of the discipline, such as conformity, interpersonal attraction, social perception, and prejudice.


title: Social psychology

text: Persuasion is an active method of influencing that attempts to guide people toward the adoption of an attitude, idea, or behavior by rational or emotive means. Persuasion relies on appeals rather than strong pressure or coercion. The process of persuasion has been found to be influenced by numerous variables that generally fall into one of five major categories:


title: Social psychology

text: Dual-process theories of persuasion (such as the elaboration likelihood model) maintain that persuasion is mediated by two separate routes: central and peripheral. The central route of persuasion is influenced by facts and results in longer-lasting change, but requires motivation to process. The peripheral route is influenced by superficial factors (e.g. smiling, clothing) and results in shorter-lasting change, but does not require as much motivation to process.


title: Social psychology

text: Social cognition studies how people perceive, recognize, and remember information about others. Much research rests on the assertion that people think about other people differently than they do non-social, or non-human, targets. This assertion is supported by the social-cognitive deficits exhibited by people with Williams syndrome and autism.


title: Social psychology

text: A major research topic in social cognition is attribution. Attributions are explanations of behavior, either one's own behavior or the behavior of others.


title: Social psychology

text: One element of attribution ascribes the cause of behavior to internal and external factors. An internal, or dispositional, attribution reasons that a behavior is caused by inner traits such as personality, disposition, character, and ability. An external, or situational, attribution reasons that a behavior is caused by situational elements such as the weather.A second element of attribution ascribes the cause of behavior to stable and unstable factors (i.e., whether the behavior will be repeated or changed under similar circumstances). Individuals also attribute causes of behavior to controllable and uncontrollable factors (i.e., how much control one has over the situation at hand).


title: Social psychology

text: Numerous biases in the attribution process have been discovered. For instance, the fundamental attribution error is the bias towards make dispositional attributions for other people's behavior. The actor-observer bias is an extension of the theory, positing that tendency exists to make dispositional attributions for other people's behavior and situational attributions for one's own. The self-serving bias is the tendency to attribute dispositional causes for successes, and situational causes for failure, particularly when self-esteem is threatened. This leads to assuming one's successes are from innate traits, and one's failures are due to situations.


title: Social psychology

text: Heuristics are cognitive shortcuts which are used to make decisions in lieu of conscious reasoning. The availability heuristic occurs when people estimate the probability of an outcome based on how easy that outcome is to imagine. As such, vivid or highly memorable possibilities will be perceived as more likely than those that are harder to picture or difficult to understand. The representativeness heuristic is a shortcut people use to categorize something based on how similar it is to a prototype they know of. Numerous other biases have been found by social cognition researchers. The hindsight bias is a false memory of having predicted events, or an exaggeration of actual predictions, after becoming aware of the outcome. The confirmation bias is a type of bias leading to the tendency to search for or interpret information in a way that confirms one's preconceptions.


title: Social psychology

text: Schemas are generalized mental representations that organize knowledge and guide information processing. They organize social information and experiences. Schemas often operate automatically and unconsciously. This leads to biases in perception and memory. Schemas may induce expectations that lead us to see something that is not there. One experiment found that people are more likely to misperceive a weapon in the hands of a black man than a white man. This type of schema is a stereotype, a generalized set of beliefs about a particular group of people (when incorrect, an ultimate attribution error). Stereotypes are often related to negative or preferential attitudes and behavior. Schemas for behaviors (e.g., going to a restaurant, doing laundry) are known as "scripts".


title: Social psychology

text: Self-concept is the whole sum of beliefs that people have about themselves. The self-concept is made up of cognitive aspects called self-schemas—beliefs that people have about themselves and that guide the processing of self-referential information. For example, an athlete at a university would have multiple selves that would process different information pertinent to each self: the student would be oneself, who would process information pertinent to a student (taking notes in class, completing a homework assignment, etc.); the athlete would be the self who processes information about things related to being an athlete. These selves are part of one's identity and the self-referential information is that which relies on the appropriate self to process and react to it.


title: Social psychology

text: There are many theories on the perception of our own behavior. Leon Festinger's 1954 "social comparison theory" posits that people evaluate their own abilities and opinions by comparing themselves to others when they are uncertain of their own ability or opinions. Daryl Bem's 1972 "self-perception theory" claims that when internal cues are difficult to interpret, people gain self-insight by observing their own behavior. There is also the "facial feedback hypothesis": changes in facial expression can lead to corresponding changes in emotion.


title: Social psychology

text: Social influence is an overarching term that denotes the persuasive effects people have on each other. It is seen as a fundamental concept in social psychology. The study of it overlaps considerably with research on attitudes and persuasion. The three main areas of social influence include conformity, compliance, and obedience. Social influence is also closely related to the study of group dynamics, as most effects of influence are strongest when they take place in social groups.


title: Social psychology

text: The first major area of social influence is conformity. Conformity is defined as the tendency to act or think like other members of a group. The identity of members within a group (i.e., status), similarity, expertise, as well as cohesion, prior commitment, and accountability to the group help to determine the level of conformity of an individual. Individual variations among group members play a key role in the dynamic of how willing people will be to conform. Conformity is usually viewed as a negative tendency in American culture, but a certain amount of conformity is adaptive in some situations, as is nonconformity in other situations.


title: Social psychology

text: The second major area of social influence research is compliance, which refers to any change in behavior that is due to a request or suggestion from another person. The foot-in-the-door technique is a compliance method in which the persuader requests a small favor and then follows up with a larger favor (e.g., asking for the time and then asking for ten dollars). A related trick is the bait and switch, which is a disingenuous sales strategy that involves enticing potential customers with advertisements of low-priced items which turn out to be unavailable in order to sell a more expensive item.


title: Social psychology

text: The third major form of social influence is obedience; this is a change in behavior that is the result of a direct order or command from another person. Obedience as a form of compliance was dramatically highlighted by the Milgram study, wherein people were ready to administer shocks to a person in distress on a researcher's command.


title: Social psychology

text: An unusual kind of social influence is the self-fulfilling prophecy. This is a prediction that, by being made, causes itself to become true. For example, in the financial field, if it is widely believed that a crash is imminent, investors may lose confidence, sell most of their stock, and thus cause a crash. Similarly, people may expect hostility in others and induce this hostility by their own behavior.


title: Social psychology

text: Psychologists have spent decades studying the power of social influence, and the way in which it manipulates people's opinions and behavior. Specifically, social influence refers to the way in which individuals change their ideas and actions to meet the demands of a social group, received authority, social role, or a minority within a group wielding influence over the majority.


title: Social psychology

text: Social psychologists study group-related phenomena such as the behavior of crowds. A group can be defined as two or more individuals who are connected to each other by social relationships. Groups tend to interact, influence each other, and share a common identity. They have a number of emergent qualities that distinguish them from coincidental, temporary gatherings, which are termed social aggregates:


title: Social psychology

text: The shared social identity of individuals within a group influences intergroup behavior, which denotes the way in which groups behave towards and perceive each other. These perceptions and behaviors in turn define the social identity of individuals within the interacting groups.


title: Social psychology

text: The tendency to define oneself by membership in a group may lead to intergroup discrimination, which involves favorable perceptions and behaviors directed towards the in-group, but negative perceptions and behaviors directed towards the out-group.


title: Social psychology

text: Groups often moderate and improve decision making, and are frequently relied upon for these benefits, such as in committees and juries. Groups also affect performance and productivity. Social facilitation, for example, is a tendency to work harder and faster in the presence of others.


title: Social psychology

text: Another important concept in this area is deindividuation, a reduced state of self-awareness that can be caused by feelings of anonymity. Deindividuation is associated with uninhibited and sometimes dangerous behavior. It is common in crowds and mobs, but it can also be caused by a disguise, a uniform, alcohol, dark environments, or online anonymity.


title: Social psychology

text: A major area of study of people's relations to each other is interpersonal attraction, which refers to all factors that lead people to like each other, establish relationships, and (in some cases) fall in love. Several general principles of attraction have been discovered by social psychologists. One of the most important factors in interpersonal attraction is how similar two particular people are. The more similar two people are in general attitudes, backgrounds, environments, worldviews, and other traits, the more likely they will be attracted to each other.


title: Social psychology

text: Physical attractiveness is an important element of romantic relationships, particularly in the early stages characterized by high levels of passion. Later on, similarity and other compatibility factors become more important, and the type of love people experience shifts from passionate to companionate. In 1986, Robert Sternberg suggested that there are actually three components of love: intimacy, passion, and commitment. When two (or more) people experience all three, they are said to be in a state of consummate love.


title: Social psychology

text: According to social exchange theory, relationships are based on rational choice and cost-benefit analysis. A person may leave a relationship if their partner's "costs" begin to outweigh their benefits, especially if there are good alternatives available. This theory is similar to the minimax principle proposed by mathematicians and economists. With time, long-term relationships tend to become communal rather than simply based on exchange.


title: Social psychology

text: Social psychology is an empirical science that attempts to answer questions about human behavior by testing hypotheses. Careful attention to research design, sampling, and statistical analysis is important in social psychology.


title: Social psychology

text: Whenever possible, social psychologists rely on controlled experimentation, which requires the manipulation of one or more independent variables in order to examine the effect on a dependent variable. Experiments are useful in social psychology because they are high in internal validity, meaning that they are free from the influence of confounding or extraneous variables, and so are more likely to accurately indicate a causal relationship. However, the small samples used in controlled experiments are typically low in external validity, or the degree to which the results can be generalized to the larger population. There is usually a trade-off between experimental control (internal validity) and being able to generalize to the population (external validity).


title: Social psychology

text: Because it is usually impossible to test everyone, research tends to be conducted on a sample of persons from the wider population. Social psychologists frequently use survey research when they are interested in results that are high in external validity. Surveys use various forms of random sampling to obtain a sample of respondents that is representative of a population. This type of research is usually descriptive or correlational because there is no experimental control over variables. Some psychologists have raised concerns for social psychological research relying too heavily on studies conducted on university undergraduates in academic settings, or participants from crowdsourcing labor markets such as Amazon Mechanical Turk. In a 1986 study by David O. Sears, over 70% of experiments used North American undergraduates as subjects, a subset of the population that is unrepresentative of the population as a whole.


title: Social psychology

text: Regardless of which method has been chosen, social psychologists statistically review the significance of their results before accepting them in evaluating an underlying hypothesis. Statistics and probability testing define what constitutes a significant finding, which can be as low as 5% or less, and is unlikely due to chance. Replication testing is also important in ensuring that the results are valid and not due to chance. False positive conclusions, often resulting from the pressure to publish or the author's own confirmation bias, are a hazard in the field.

text: The Asch conformity experiments used a line-length estimation task to demonstrate the power of people's impulses to conform with other members in a small group. The task was designed to be easy to assess but wrong answers were deliberately given by at least some, oftentimes most, of the other participants. In well over a third of the trials, participants conformed to the majority, even though the majority judgment was clearly wrong. Seventy-five percent of the participants conformed at least once during the experiment. Additional manipulations of the experiment showed that participant conformity decreased when at least one other individual failed to conform but increased when the individual began conforming or withdrew from the experiment. Also, participant conformity increased substantially as the number of "incorrect" individuals increased from one to three, and remained high as the incorrect majority grew. Participants with three other, incorrect participants made mistakes 31.8% of the time, while those with one or two incorrect participants made mistakes only 3.6% and 13.6% of the time, respectively.

text: In Leon Festinger's cognitive dissonance experiment, participants were divided into two groups and were asked to perform a boring task. Both groups were later asked to dishonestly give their opinion of the task, but were rewarded according to two different pay scales. At the end of the study, some participants were paid $1 to say that they enjoyed the task, while the group of participants were paid $20 to tell the same lie. The first group ($1) later reported liking the task better than the second group ($20). Festinger's explanation was that for people in the first group, being paid only $1 was not sufficient incentive. This led them to experience dissonance, or discomfort and internal conflict. They could only overcome that dissonance by justifying their lies. They did this by changing their previously unfavorable attitudes about the task. Being paid $20 provided a reason for doing the boring task, which resulted in no dissonance.


title: Social psychology

text: The Milgram experiment was designed to study how far people would go in obeying an authority figure. The experiment showed that normal American citizens would follow orders even when they believed they were causing an innocent person to suffer or even apparently die.


title: Social psychology

text: Philip Zimbardo's Stanford prison study, a simulated exercise involving students playing at being prison guards and inmates, attempted to show how far people would go in role playing. In just a few days, the guards became brutal and cruel, and the prisoners became miserable and compliant. This was initially argued to be an important demonstration of the power of the immediate social situation and its capacity to overwhelm normal personality traits. Subsequent research has contested the initial conclusions of the study. For example, it has been pointed out that participant self-selection may have affected the participants' behavior, and that the participants' personalities influenced their reactions in a variety of ways, including how long they chose to remain in the study. The 2002 BBC prison study, designed to replicate the conditions in the Stanford study, produced conclusions that were drastically different from the initial findings.


title: Social psychology

text: Albert Bandura's Bobo doll experiment attempted to demonstrate how aggression is learned by imitation. In the experiment, 72 children, grouped based on similar levels of pre-tested aggressivity, either witnessed an aggressive or a non-aggressive actor interact with a "bobo doll." The children were then placed alone in the room with the doll and observed to see if they would imitate the same behavior of the actor they had observed. As hypothesized, the children who had witnessed the aggressive actor, imitated the behavior and proceeded to act aggressively towards the doll. Both male and female children who witnessed the non-aggressive actor behaved less aggressively towards the doll. However, boys were more likely to exhibit aggression, especially after observing the behavior from an actor of the same gender. In addition, boys were found to imitate more physical aggression, while girls displayed more verbal aggression.


title: Social psychology

text: The goal of social psychology is to understand cognition and behavior as they naturally occur in a social context, but the very act of observing people can influence and alter their behavior. For this reason, many social psychology experiments utilize deception to conceal or distort certain aspects of the study. Deception may include false cover stories, false participants (known as confederates or stooges), false feedback given to the participants, and other techniques that help remove potential obstacles to participation.


title: Social psychology

text: The practice of deception has been challenged by psychologists who maintain that deception under any circumstances is unethical and that other research strategies (e.g., role-playing) should be used instead. Unfortunately, research has shown that role-playing studies do not produce the same results as deception studies, and this has cast doubt on their validity. In addition to deception, experimenters have at times put people in potentially uncomfortable or embarrassing situations (e.g., the Milgram experiment and Stanford prison experiment), and this has also been criticized for ethical reasons.


title: Social psychology

text: Virtually all social psychology research in the modern day must pass an ethical review. At most colleges and universities, this is conducted by an ethics committee or institutional review board, which examines the proposed research to make sure that no harm is likely to come to the participants, and that the study's benefits outweigh any possible risks or discomforts to people participating.


title: Social psychology

text: Furthermore, a process of informed consent is often used to make sure that volunteers know what will be asked of them in the experiment and understand that they are allowed to quit the experiment at any time. A debriefing is typically done at the experiment's conclusion in order to reveal any deceptions used and generally make sure that the participants are unharmed by the procedures. Today, most research in social psychology involves minimal risk, or no greater risk of harm than can be expected from normal daily activities or routine psychological testing.


title: Social psychology

text: Many social psychological research findings have proven difficult to replicate, leading some to argue that social psychology is undergoing a replication crisis. A 2014 special edition of "Social Psychology" focused on replication studies, finding that a number of previously held social psychological beliefs were difficult to replicate. Likewise, a 2012 special edition of "Perspectives on Psychological Science" focused on issues ranging from publication bias to null-aversion which have contributed to the replication crisis.


title: Social psychology

text: Some factors have been identified in social psychological research as contributing to the crisis. For one, questionable research practices have been identified as common. Such practices, while not necessarily intentionally fraudulent, often involve converting undesired statistical outcomes into desired outcomes via the manipulation of statistical analyses, sample sizes, or data management systems, typically to convert non-significant findings into significant ones. Some studies have suggested that at least mild versions of these practices are prevalent.


title: Social psychology

text: Some social psychologists have also published fraudulent research that has entered into mainstream academia, most notably the admitted data fabrication by Diederik Stapel as well as allegations against others. Fraudulent research is not the main contributor to the replication crisis. Many researchers attribute the failure to replicate as a result of the difficulty of being able to recreate the exact same conditions of a study conducted many years ago, as the environment and people have changed.


title: Social psychology

text: Even before the current replication crisis, several effects in social psychology have also been found to be difficult to replicate. For example, the scientific journal "Judgment and Decision Making" has published several studies over the years that fail to provide support for the unconscious thought theory.


title: Social psychology

text: Replication failures are not unique to social psychology and are found in many fields of science. One of the consequences of the current crisis is that some areas of social psychology once considered solid, such as social priming, have come under increased scrutiny due to failure to replicate findings.


title: Geocentric model

text: In astronomy, the geocentric model (also known as geocentrism, often exemplified specifically by the Ptolemaic system) is a superseded description of the Universe with Earth at the center. Under most geocentric models, the Sun, Moon, stars, and planets all orbit Earth. The geocentric model was the predominant description of the cosmos in many European ancient civilizations, such as those of Aristotle in Classical Greece and Ptolemy in Roman Egypt.


title: Geocentric model

text: Ancient Greek, ancient Roman, and medieval philosophers usually combined the geocentric model with a spherical Earth, in contrast to the older flat-Earth model implied in some mythology. The ancient Jewish Babylonian uranography pictured a flat Earth with a dome-shaped, rigid canopy called the firmament placed over it (רקיע- rāqîa'). However, the Greek astronomer and mathematician Aristarchus of Samos (c. 310 – c. 230 BC) developed a heliocentric model placing all of the then-known planets in their correct order around the Sun. The ancient Greeks believed that the motions of the planets were circular, a view that was not challenged in Western culture until the 17th century, when Johannes Kepler postulated that orbits were heliocentric and elliptical (Kepler's first law of planetary motion). In 1687 Newton showed that elliptical orbits could be derived from his laws of gravitation.


title: Geocentric model

text: The astronomical predictions of Ptolemy's geocentric model, developed in the 2nd century CE, served as the basis for preparing astrological and astronomical charts for over 1,500 years. The geocentric model held sway into the early modern age, but from the late 16th century onward, it was gradually superseded by the heliocentric model of Copernicus (1473–1543), Galileo (1564–1642), and Kepler (1571–1630). There was much resistance to the transition between these two theories. Some felt that a new, unknown theory could not subvert an accepted consensus for geocentrism.


title: Geocentric model

text: The geocentric model entered Greek astronomy and philosophy at an early point; it can be found in pre-Socratic philosophy. In the 6th century BC, Anaximander proposed a cosmology with Earth shaped like a section of a pillar (a cylinder), held aloft at the center of everything. The Sun, Moon, and planets were holes in invisible wheels surrounding Earth; through the holes, humans could see concealed fire. About the same time, Pythagoras thought that the Earth was a sphere (in accordance with observations of eclipses), but not at the center; he believed that it was in motion around an unseen fire. Later these views were combined, so most educated Greeks from the 4th century BC on thought that the Earth was a sphere at the center of the universe.


title: Geocentric model

text: In the 4th century BC, two influential Greek philosophers, Plato and his student Aristotle, wrote works based on the geocentric model. According to Plato, the Earth was a sphere, stationary at the center of the universe. The stars and planets were carried around the Earth on spheres or circles, arranged in the order (outwards from the center): Moon, Sun, Venus, Mercury, Mars, Jupiter, Saturn, fixed stars, with the fixed stars located on the celestial sphere. In his "Myth of Er", a section of the "Republic", Plato describes the cosmos as the Spindle of Necessity, attended by the Sirens and turned by the three Fates. Eudoxus of Cnidus, who worked with Plato, developed a less mythical, more mathematical explanation of the planets' motion based on Plato's dictum stating that all phenomena in the heavens can be explained with uniform circular motion. Aristotle elaborated on Eudoxus' system.


title: Geocentric model

text: In the fully developed Aristotelian system, the spherical Earth is at the center of the universe, and all other heavenly bodies are attached to 47–55 transparent, rotating spheres surrounding the Earth, all concentric with it. (The number is so high because several spheres are needed for each planet.) These spheres, known as crystalline spheres, all moved at different uniform speeds to create the revolution of bodies around the Earth. They were composed of an incorruptible substance called aether. Aristotle believed that the Moon was in the innermost sphere and therefore touches the realm of Earth, causing the dark spots (macula) and the ability to go through lunar phases. He further described his system by explaining the natural tendencies of the terrestrial elements: Earth, water, fire, air, as well as celestial aether. His system held that Earth was the heaviest element, with the strongest movement towards the center, thus water formed a layer surrounding the sphere of Earth. The tendency of air and fire, on the other hand, was to move upwards, away from the center, with fire being lighter than air. Beyond the layer of fire, were the solid spheres of aether in which the celestial bodies were embedded. They, themselves, were also entirely composed of aether.


title: Geocentric model

text: Adherence to the geocentric model stemmed largely from several important observations. First of all, if the Earth did move, then one ought to be able to observe the shifting of the fixed stars due to stellar parallax. In short, if the Earth was moving, the shapes of the constellations should change considerably over the course of a year. If they did not appear to move, the stars are either much farther away than the Sun and the planets than previously conceived, making their motion undetectable, or in reality they are not moving at all. Because the stars were actually much further away than Greek astronomers postulated (making movement extremely subtle), stellar parallax was not detected until the 19th century. Therefore, the Greeks chose the simpler of the two explanations. Another observation used in favor of the geocentric model at the time was the apparent consistency of Venus' luminosity, which implies that it is usually about the same distance from Earth, which in turn is more consistent with geocentrism than heliocentrism. In reality, that is because the loss of light caused by Venus' phases compensates for the increase in apparent size caused by its varying distance from Earth. Objectors to heliocentrism noted that terrestrial bodies naturally tend to come to rest as near as possible to the center of the Earth. Further barring the opportunity to fall closer the center, terrestrial bodies tend not to move unless forced by an outside object, or transformed to a different element by heat or moisture.


title: Geocentric model

text: Atmospheric explanations for many phenomena were preferred because the Eudoxan–Aristotelian model based on perfectly concentric spheres was not intended to explain changes in the brightness of the planets due to a change in distance. Eventually, perfectly concentric spheres were abandoned as it was impossible to develop a sufficiently accurate model under that ideal. However, while providing for similar explanations, the later deferent and epicycle model was flexible enough to accommodate observations for many centuries.


title: Geocentric model

text: Although the basic tenets of Greek geocentrism were established by the time of Aristotle, the details of his system did not become standard. The Ptolemaic system, developed by the Hellenistic astronomer Claudius Ptolemaeus in the 2nd century AD finally standardised geocentrism. His main astronomical work, the "Almagest", was the culmination of centuries of work by Hellenic, Hellenistic and Babylonian astronomers. For over a millennium European and Islamic astronomers assumed it was the correct cosmological model. Because of its influence, people sometimes wrongly think the Ptolemaic system is identical with the geocentric model.


title: Geocentric model

text: Ptolemy argued that the Earth was a sphere in the center of the universe, from the simple observation that half the stars were above the horizon and half were below the horizon at any time (stars on rotating stellar sphere), and the assumption that the stars were all at some modest distance from the center of the universe. If the Earth was substantially displaced from the center, this division into visible and invisible stars would not be equal.


title: Geocentric model

text: In the Ptolemaic system, each planet is moved by a system of two spheres: one called its deferent; the other, its epicycle. The deferent is a circle whose center point, called the eccentric and marked in the diagram with an X, is distant from the Earth. The original purpose of the eccentric was to account for the difference in length of the seasons (northern autumn was about five days shorter than spring during this time period) by placing the Earth away from the center of rotation of the rest of the universe. Another sphere, the epicycle, is embedded inside the deferent sphere and is represented by the smaller dotted line to the right. A given planet then moves around the epicycle at the same time the epicycle moves along the path marked by the deferent. These combined movements cause the given planet to move closer to and further away from the Earth at different points in its orbit, and explained the observation that planets slowed down, stopped, and moved backward in retrograde motion, and then again reversed to resume normal, or prograde, motion.


title: Geocentric model

text: The deferent-and-epicycle model had been used by Greek astronomers for centuries along with the idea of the eccentric (a deferent which center is slightly away from the Earth), which was even older. In the illustration, the center of the deferent is not the Earth but the spot marked X, making it eccentric (from the Greek ἐκ "ec-" meaning "from," and κέντρον "kentron" meaning "center"), from which the spot takes its name. Unfortunately, the system that was available in Ptolemy's time did not quite match observations, even though it was improved over Hipparchus' system. Most noticeably the size of a planet's retrograde loop (especially that of Mars) would be smaller, and sometimes larger, than expected, resulting in positional errors of as much as 30 degrees. To alleviate the problem, Ptolemy developed the equant. The equant was a point near the center of a planet's orbit which, if you were to stand there and watch, the center of the planet's epicycle would always appear to move at uniform speed; all other locations would see non-uniform speed, like on the Earth. By using an equant, Ptolemy claimed to keep motion which was uniform and circular, although it departed from the Platonic ideal of uniform circular motion. The resultant system, which eventually came to be widely accepted in the west, seems unwieldy to modern astronomers; each planet required an epicycle revolving on a deferent, offset by an equant which was different for each planet. It predicted various celestial motions, including the beginning and end of retrograde motion, to within a maximum error of 10 degrees, considerably better than without the equant.


title: Geocentric model

text: The model with epicycles is in fact a very good model of an elliptical orbit with low eccentricity. The well known ellipse shape does not appear to a noticeable extent when the eccentricity is less than 5%, but the offset distance of the "center" (in fact the focus occupied by the sun) is very noticeable even with low eccentricities as possessed by the planets.


title: Geocentric model

text: To summarize, Ptolemy devised a system that was compatible with Aristotelian philosophy and managed to track actual observations and predict future movement mostly to within the limits of the next 1000 years of observations. The observed motions and his mechanisms for explaining them include:


title: Geocentric model

text: The geocentric model was eventually replaced by the heliocentric model. Copernican heliocentrism could remove Ptolemy's epicycles because the retrograde motion could be seen to be the result of the combination of Earth and planet movement and speeds. Copernicus felt strongly that equants were a violation of Aristotelian purity, and proved that replacement of the equant with a pair of new epicycles was entirely equivalent. Astronomers often continued using the equants instead of the epicycles because the former was easier to calculate, and gave the same result.


title: Geocentric model

text: It has been determined, in fact, that the Copernican, Ptolemaic and even the Tychonic models provided identical results to identical inputs. They are computationally equivalent. It wasn't until Kepler demonstrated a physical observation that could show that the physical sun is directly involved in determining an orbit that a new model was required.


title: Geocentric model

text: Ptolemy did not invent or work out this order, which aligns with the ancient Seven Heavens religious cosmology common to the major Eurasian religious traditions. It also follows the decreasing orbital periods of the Moon, Sun, planets and stars.


title: Geocentric model

text: Muslim astronomers generally accepted the Ptolemaic system and the geocentric model, but by the 10th century texts appeared regularly whose subject matter was doubts concerning Ptolemy ("shukūk"). Several Muslim scholars questioned the Earth's apparent immobility and centrality within the universe. Some Muslim astronomers believed that the Earth rotates around its axis, such as Abu Sa'id al-Sijzi (d. circa 1020). According to al-Biruni, Sijzi invented an astrolabe called "al-zūraqī" based on a belief held by some of his contemporaries "that the motion we see is due to the Earth's movement and not to that of the sky." The prevalence of this view is further confirmed by a reference from the 13th century which states: According to the geometers [or engineers] ("muhandisīn"), the Earth is in constant circular motion, and what appears to be the motion of the heavens is actually due to the motion of the Earth and not the stars. Early in the 11th century Alhazen wrote a scathing critique of Ptolemy's model in his "Doubts on Ptolemy" (c. 1028), which some have interpreted to imply he was criticizing Ptolemy's geocentrism, but most agree that he was actually criticizing the details of Ptolemy's model rather than his geocentrism.


title: Geocentric model

text: In the 12th century, Arzachel departed from the ancient Greek idea of uniform circular motions by hypothesizing that the planet Mercury moves in an elliptic orbit, while Alpetragius proposed a planetary model that abandoned the equant, epicycle and eccentric mechanisms, though this resulted in a system that was mathematically less accurate. Alpetragius also declared the Ptolemaic system as an imaginary model that was successful at predicting planetary positions but not real or physical. His alternative system spread through most of Europe during the 13th century.


title: Geocentric model

text: Fakhr al-Din al-Razi (1149–1209), in dealing with his conception of physics and the physical world in his "Matalib", rejects the Aristotelian and Avicennian notion of the Earth's centrality within the universe, but instead argues that there are "a thousand thousand worlds ("alfa alfi 'awalim") beyond this world such that each one of those worlds be bigger and more massive than this world as well as having the like of what this world has." To support his theological argument, he cites the Qur'anic verse, "All praise belongs to God, Lord of the Worlds," emphasizing the term "Worlds."


title: Geocentric model

text: The "Maragha Revolution" refers to the Maragha school's revolution against Ptolemaic astronomy. The "Maragha school" was an astronomical tradition beginning in the Maragha observatory and continuing with astronomers from the Damascus mosque and Samarkand observatory. Like their Andalusian predecessors, the Maragha astronomers attempted to solve the equant problem (the circle around whose circumference a planet or the center of an epicycle was conceived to move uniformly) and produce alternative configurations to the Ptolemaic model without abandoning geocentrism. They were more successful than their Andalusian predecessors in producing non-Ptolemaic configurations which eliminated the equant and eccentrics, were more accurate than the Ptolemaic model in numerically predicting planetary positions, and were in better agreement with empirical observations. The most important of the Maragha astronomers included Mo'ayyeduddin Urdi (d. 1266), Nasīr al-Dīn al-Tūsī (1201–1274), Qutb al-Din al-Shirazi (1236–1311), Ibn al-Shatir (1304–1375), Ali Qushji (c. 1474), Al-Birjandi (d. 1525), and Shams al-Din al-Khafri (d. 1550). Ibn al-Shatir, the Damascene astronomer (1304–1375 AD) working at the Umayyad Mosque, wrote a major book entitled "Kitab Nihayat al-Sul fi Tashih al-Usul" ("A Final Inquiry Concerning the Rectification of Planetary Theory") on a theory which departs largely from the Ptolemaic system known at that time. In his book, "Ibn al-Shatir, an Arab astronomer of the fourteenth century", E. S. Kennedy wrote "what is of most interest, however, is that Ibn al-Shatir's lunar theory, except for trivial differences in parameters, is identical with that of Copernicus (1473–1543 AD)." The discovery that the models of Ibn al-Shatir are mathematically identical to those of Copernicus suggests the possible transmission of these models to Europe. At the Maragha and Samarkand observatories, the Earth's rotation was discussed by al-Tusi and Ali Qushji (b. 1403); the arguments and evidence they used resemble those used by Copernicus to support the Earth's motion.


title: Geocentric model

text: However, the Maragha school never made the paradigm shift to heliocentrism. The influence of the Maragha school on Copernicus remains speculative, since there is no documentary evidence to prove it. The possibility that Copernicus independently developed the Tusi couple remains open, since no researcher has yet demonstrated that he knew about Tusi's work or that of the Maragha school.


title: Geocentric model

text: Not all Greeks agreed with the geocentric model. The Pythagorean system has already been mentioned; some Pythagoreans believed the Earth to be one of several planets going around a central fire. Hicetas and Ecphantus, two Pythagoreans of the 5th century BC, and Heraclides Ponticus in the 4th century BC, believed that the Earth rotated on its axis but remained at the center of the universe. Such a system still qualifies as geocentric. It was revived in the Middle Ages by Jean Buridan. Heraclides Ponticus was once thought to have proposed that both Venus and Mercury went around the Sun rather than the Earth, but it is now known that he didn't. Martianus Capella definitely put Mercury and Venus in orbit around the Sun. Aristarchus of Samos wrote a work, which has not survived, on heliocentrism, saying that the Sun was at the center of the universe, while the Earth and other planets revolved around it. His theory was not popular, and he had one named follower, Seleucus of Seleucia.


title: Geocentric model

text: Epicurus was the most radical. He correctly realized in the 4th century BC that the universe does not have any single center. This theory was widely accepted by the later Epicureans and was notably defended by Lucretius in his poem De rerum natura.


title: Geocentric model

text: In 1543, the geocentric system met its first serious challenge with the publication of Copernicus' "De revolutionibus orbium coelestium" ("On the Revolutions of the Heavenly Spheres"), which posited that the Earth and the other planets instead revolved around the Sun. The geocentric system was still held for many years afterwards, as at the time the Copernican system did not offer better predictions than the geocentric system, and it posed problems for both natural philosophy and scripture. The Copernican system was no more accurate than Ptolemy's system, because it still used circular orbits. This was not altered until Johannes Kepler postulated that they were elliptical (Kepler's first law of planetary motion).


title: Geocentric model

text: With the invention of the telescope in 1609, observations made by Galileo Galilei (such as that Jupiter has moons) called into question some of the tenets of geocentrism but did not seriously threaten it. Because he observed dark "spots" on the Moon, craters, he remarked that the moon was not a perfect celestial body as had been previously conceived. This was the first time someone could see imperfections on a celestial body that was supposed to be composed of perfect aether. As such, because the Moon's imperfections could now be related to those seen on Earth, one could argue that neither was unique: rather, they were both just celestial bodies made from Earth-like material. Galileo could also see the moons of Jupiter, which he dedicated to Cosimo II de' Medici, and stated that they orbited around Jupiter, not Earth. This was a significant claim as it would mean not only that not everything revolved around Earth as stated in the Ptolemaic model, but also showed a secondary celestial body could orbit a moving celestial body, strengthening the heliocentric argument that a moving Earth could retain the Moon. Galileo's observations were verified by other astronomers of the time period who quickly adopted use of the telescope, including Christoph Scheiner, Johannes Kepler, and Giovan Paulo Lembo.


title: Geocentric model

text: In December 1610, Galileo Galilei used his telescope to observe that Venus showed all phases, just like the Moon. He thought that while this observation was incompatible with the Ptolemaic system, it was a natural consequence of the heliocentric system.


title: Geocentric model

text: However, Ptolemy placed Venus' deferent and epicycle entirely inside the sphere of the Sun (between the Sun and Mercury), but this was arbitrary; he could just as easily have swapped Venus and Mercury and put them on the other side of the Sun, or made any other arrangement of Venus and Mercury, as long as they were always near a line running from the Earth through the Sun, such as placing the center of the Venus epicycle near the Sun. In this case, if the Sun is the source of all the light, under the Ptolemaic system:


title: Geocentric model

text: This showed that with a Ptolemaic cosmology, the Venus epicycle can be neither completely inside nor completely outside of the orbit of the Sun. As a result, Ptolemaics abandoned the idea that the epicycle of Venus was completely inside the Sun, and later 17th-century competition between astronomical cosmologies focused on variations of Tycho Brahe's Tychonic system (in which the Earth was still at the center of the universe, and around it revolved the Sun, but all other planets revolved around the Sun in one massive set of epicycles), or variations on the Copernican system.


title: Geocentric model

text: Johannes Kepler analysed Tycho Brahe's famously accurate observations and afterwards constructed his three laws in 1609 and 1619, based on a heliocentric view where the planets move in elliptical paths. Using these laws, he was the first astronomer to successfully predict a transit of Venus for the year 1631. The change from circular orbits to elliptical planetary paths dramatically improved the accuracy of celestial observations and predictions. Because the heliocentric model devised by Copernicus was no more accurate than Ptolemy's system, new observations were needed to persuade those who still adhered to the geocentric model. However, Kepler's laws based on Brahe's data became a problem which geocentrists could not easily overcome.


title: Geocentric model

text: In 1687, Isaac Newton stated the law of universal gravitation, described earlier as a hypothesis by Robert Hooke and others. His main achievement was to mathematically derive Kepler's laws of planetary motion from the law of gravitation, thus helping to prove the latter. This introduced gravitation as the force which both kept the Earth and planets moving through the universe and also kept the atmosphere from flying away. The theory of gravity allowed scientists to rapidly construct a plausible heliocentric model for the Solar System. In his "Principia", Newton explained his theory of how gravity, previously thought to be a mysterious, unexplained occult force, directed the movements of celestial bodies, and kept our Solar System in working order. His descriptions of centripetal force were a breakthrough in scientific thought, using the newly developed mathematical discipline of differential calculus, finally replacing the previous schools of scientific thought, which had been dominated by Aristotle and Ptolemy. However, the process was gradual.


title: Geocentric model

text: Several empirical tests of Newton's theory, explaining the longer period of oscillation of a pendulum at the equator and the differing size of a degree of latitude, would gradually become available between 1673 and 1738. In addition, stellar aberration was observed by Robert Hooke in 1674, and tested in a series of observations by Jean Picard over a period of ten years, finishing in 1680. However, it was not explained until 1729, when James Bradley provided an approximate explanation in terms of the Earth's revolution about the Sun.


title: Geocentric model

text: In 1838, astronomer Friedrich Wilhelm Bessel measured the parallax of the star 61 Cygni successfully, and disproved Ptolemy's claim that parallax motion did not exist. This finally confirmed the assumptions made by Copernicus, providing accurate, dependable scientific observations, and conclusively displaying how distant stars are from Earth.


title: Geocentric model

text: A geocentric frame is useful for many everyday activities and most laboratory experiments, but is a less appropriate choice for Solar System mechanics and space travel. While a heliocentric frame is most useful in those cases, galactic and extragalactic astronomy is easier if the Sun is treated as neither stationary nor the center of the universe, but rather rotating around the center of our galaxy, while in turn our galaxy is also not at rest in the cosmic background.


title: Geocentric model

text: Albert Einstein and Leopold Infeld wrote in "The Evolution of Physics" (1938): "Can we formulate physical laws so that they are valid for all CS (=coordinate systems), not only those moving uniformly, but also those moving quite arbitrarily, relative to each other? If this can be done, our difficulties will be over. We shall then be able to apply the laws of nature to any CS. The struggle, so violent in the early days of science, between the views of Ptolemy and Copernicus would then be quite meaningless. Either CS could be used with equal justification. The two sentences, 'the sun is at rest and the Earth moves', or 'the sun moves and the Earth is at rest', would simply mean two different conventions concerning two different CS.

text: Could we build a real relativistic physics valid in all CS; a physics in which there would be no place for absolute, but only for relative, motion? This is indeed possible!"


title: Geocentric model

text: Despite giving more respectability to the geocentric view than Newtonian physics does, relativity is not geocentric. Rather, relativity states that the Sun, the Earth, the Moon, Jupiter, or any other point for that matter could be chosen as a center of the Solar System with equal validity.


title: Geocentric model

text: Relativity agrees with Newtonian predictions that regardless of whether the Sun or the Earth are chosen arbitrarily as the center of the coordinate system describing the Solar System, the paths of the planets form (roughly) ellipses with respect to the Sun, not the Earth. With respect to the average reference frame of the fixed stars, the planets do indeed move around the Sun, which due to its much larger mass, moves far less than its own diameter and the gravity of which is dominant in determining the orbits of the planets (in other words, the center of mass of the Solar System is near the center of the Sun). The Earth and Moon are much closer to being a binary planet; the center of mass around which they both rotate is still inside the Earth, but is about or 72.6% of the Earth's radius away from the centre of the Earth (thus closer to the surface than the center).


title: Geocentric model

text: What the principle of relativity points out is that correct mathematical calculations can be made regardless of the reference frame chosen, and these will all agree with each other as to the predictions of actual motions of bodies with respect to each other. It is not necessary to choose the object in the Solar System with the largest gravitational field as the center of the coordinate system in order to predict the motions of planetary bodies, though doing so may make calculations easier to perform or interpret. A geocentric coordinate system can be more convenient when dealing only with bodies mostly influenced by the gravity of the Earth (such as artificial satellites and the Moon), or when calculating what the sky will look like when viewed from Earth (as opposed to an imaginary observer looking down on the entire Solar System, where a different coordinate system might be more convenient).


title: Geocentric model

text: The Ptolemaic model of the solar system held sway into the early modern age; from the late 16th century onward it was gradually replaced as the consensus description by the heliocentric model. Geocentrism as a separate religious belief, however, never completely died out. In the United States between 1870 and 1920, for example, various members of the Lutheran Church–Missouri Synod published articles disparaging Copernican astronomy and promoting geocentrism. However, in the 1902 "Theological Quarterly", A. L. Graebner observed that the synod had no doctrinal position on geocentrism, heliocentrism, or any scientific model, unless it were to contradict Scripture. He stated that any possible declarations of geocentrists within the synod did not set the position of the church body as a whole.


title: Geocentric model

text: Articles arguing that geocentrism was the biblical perspective appeared in some early creation science newsletters pointing to some passages in the Bible, which, when taken literally, indicate that the daily apparent motions of the Sun and the Moon are due to their actual motions around the Earth rather than due to the rotation of the Earth about its axis. For example, in , the Sun and Moon are said to stop in the sky, and in Psalms the world is described as immobile. says in part, "the world is established, firm and secure". Contemporary advocates for such religious beliefs include Robert Sungenis (author of the 2006 book "Galileo Was Wrong" and the 2014 pseudo-documentary film "The Principle"). These people subscribe to the view that a plain reading of the Bible contains an accurate account of the manner in which the universe was created and requires a geocentric worldview. Most contemporary creationist organizations reject such perspectives.


title: Geocentric model

text: According to a report released in 2014 by the National Science Foundation, 26% of Americans surveyed believe that the sun revolves around the Earth.


title: Geocentric model

text: Morris Berman quotes a 2006 survey that show currently some 20% of the U.S. population believe that the Sun goes around the Earth (geocentricism) rather than the Earth goes around the Sun (heliocentricism), while a further 9% claimed not to know. Polls conducted by Gallup in the 1990s found that 16% of Germans, 18% of Americans and 19% of Britons hold that the Sun revolves around the Earth. A study conducted in 2005 by Jon D. Miller of Northwestern University, an expert in the public understanding of science and technology, found that about 20%, or one in five, of American adults believe that the Sun orbits the Earth. According to 2011 VTSIOM poll, 32% of Russians believe that the Sun orbits the Earth.


title: Geocentric model

text: The famous Galileo affair pitted the geocentric model against the claims of Galileo. In regards to the theological basis for such an argument, two Popes addressed the question of whether the use of phenomenological language would compel one to admit an error in Scripture. Both taught that it would not. Pope Leo XIII (1878–1903) wrote:


title: Geocentric model

text: Maurice Finocchiaro, author of a book on the Galileo affair, notes that this is "a view of the relationship between biblical interpretation and scientific investigation that corresponds to the one advanced by Galileo in the "Letter to the Grand Duchess Christina". Pope Pius XII (1939–1958) repeated his predecessor's teaching:


title: Geocentric model

text: In 1664, Pope Alexander VII republished the "Index Librorum Prohibitorum" ("List of Prohibited Books") and attached the various decrees connected with those books, including those concerned with heliocentrism. He stated in a Papal Bull that his purpose in doing so was that "the succession of things done from the beginning might be made known ["quo rei ab initio gestae series innotescat"]".


title: Geocentric model

text: The position of the curia evolved slowly over the centuries towards permitting the heliocentric view. In 1757, during the papacy of Benedict XIV, the Congregation of the Index withdrew the decree which prohibited "all" books teaching the Earth's motion, although the "Dialogue" and a few other books continued to be explicitly included. In 1820, the Congregation of the Holy Office, with the pope's approval, decreed that Catholic astronomer Giuseppe Settele was allowed to treat the Earth's motion as an established fact and removed any obstacle for Catholics to hold to the motion of the Earth:


title: Geocentric model

text: In 1822, the Congregation of the Holy Office removed the prohibition on the publication of books treating of the Earth's motion in accordance with modern astronomy and Pope Pius VII ratified the decision:


title: Geocentric model

text: The 1835 edition of the Catholic "List of Prohibited Books" for the first time omits the "Dialogue" from the list. In his 1921 papal encyclical, "In praeclara summorum", Pope Benedict XV stated that, "though this Earth on which we live may not be the center of the universe as at one time was thought, it was the scene of the original happiness of our first ancestors, witness of their unhappy fall, as too of the Redemption of mankind through the Passion and Death of Jesus Christ". In 1965 the Second Vatican Council stated that, "Consequently, we cannot but deplore certain habits of mind, which are sometimes found too among Christians, which do not sufficiently attend to the rightful independence of science and which, from the arguments and controversies they spark, lead many minds to conclude that faith and science are mutually opposed." The footnote on this statement is to Msgr. Pio Paschini's, "Vita e opere di Galileo Galilei", 2 volumes, Vatican Press (1964). Pope John Paul II regretted the treatment which Galileo received, in a speech to the Pontifical Academy of Sciences in 1992. The Pope declared the incident to be based on a "tragic mutual miscomprehension". He further stated:


title: Geocentric model

text: A few Orthodox Jewish leaders maintain a geocentric model of the universe based on the aforementioned Biblical verses and an interpretation of Maimonides to the effect that he ruled that the Earth is orbited by the Sun. The Lubavitcher Rebbe also explained that geocentrism is defensible based on the theory of relativity, which establishes that "when two bodies in space are in motion relative to one another, ... science declares with absolute certainty that from the scientific point of view both possibilities are equally valid, namely that the Earth revolves around the sun, or the sun revolves around the Earth", although he also went on to refer to people who believed in geocentrism as "remaining in the world of Copernicus".


title: Geocentric model

text: The Zohar states: "The entire world and those upon it, spin round in a circle like a ball, both those at the bottom of the ball and those at the top. All God's creatures, wherever they live on the different parts of the ball, look different (in color, in their features) because the air is different in each place, but they stand erect as all other human beings, therefore, there are places in the world where, when some have light, others have darkness; when some have day, others have night."


title: Geocentric model

text: While geocentrism is important in Maimonides' calendar calculations, the great majority of Jewish religious scholars, who accept the divinity of the Bible and accept many of his rulings as legally binding, do not believe that the Bible or Maimonides command a belief in geocentrism.


title: Geocentric model

text: After the translation movement led by the Mu'tazila, which included the translation of Almagest from Latin to Arabic, Muslims adopted and refined the geocentric model of Ptolemy, which they believed correlated with the teachings of Islam.


title: Geocentric model

text: Prominent cases of modern geocentrism are very isolated. Very few individuals promoted a geocentric view of the universe. One of them was Ahmed Raza Khan Barelvi, a Sunni scholar of Indian subcontinent. He rejected the heliocentric model and wrote a book that explains the movement of the sun, moon and other planets around the Earth.


title: Geocentric model

text: The geocentric (Ptolemaic) model of the Solar System is a critical mathematical system for the design of geared planetary orbital projection within electro-optical planetarium projectors.


title: Geocentric model

text: The movement of the planets across the projected sky require the use of circular gears and linear guiding rods for the projectors, and the Ptolemaic system permits the mechanical engineering design of these components to then project the position of the planets with sufficient accuracy to allow the resulting instruments projection to hold value in teaching celestial navigation, among other applications in observational astronomy.


title: Geocentric model

text: In turn, the projection of the celestial sphere, still used for teaching purposes and sometimes for navigation, is also based on a geocentric system which in effect ignores parallax. However this effect is negligible at the scale of accuracy that applies to an electro-mechanical planetarium.


title: Geocentric model

text: In the era of the digital planetarium, the Ptolemaic system retains value in offering a computationally less intensive means to forecast the projection of the planets, in which the Keplerian model acts as a numerical correction to the Ptolemaic system, rather than replacing it fully in projectors of this type.


title: Ramanathaswamy Temple

text: Ramanathaswamy Temple ("Rāmanātasvāmi Kōyil") is a Hindu temple dedicated to the god Shiva located on Rameswaram island in the state of Tamil Nadu, India. It is also one of the twelve Jyotirlinga temples. It is one of the 275 Paadal Petra Sthalams, where three of the most revered Nayanars (Saivite saints), Appar, Sundarar and Tirugnana Sambandar, have glorified the temple with their songs. The temple was expanded during the 12th century by the Pandya Dynasty, and its principal shrine’s sanctum was renovated by Jeyaveera Cinkaiariyan and his successor Gunaveera Cinkaiariyan, monarchs of the Jaffna kingdom. The temple has the longest corridor among all Hindu temples in India. It was built by King Muthuramalinga Sethupathiy. The temple, located in Rameswaram, is considered a holy pilgrimage site for Shaivites, Vaishnavites and Smarthas. Mythological accounts depict the presiding deity, the Lingam of Ramanathaswamy (Shiva), as having been established and worshiped by Rama, before he crossed his bridge to the present-day island of Sri Lanka.


title: Ramanathaswamy Temple

text: According to Hindu epic Ramayana, Rama, the seventh avatar of the god Vishnu, prayed to Shiva here to absolve any sins that he might have committed during his war against the demon-king Ravana in Sri Lanka. According to the Puranas (Hindu scriptures), upon the advice of sages, Rama along with his wife Sita and his brother Lakshmana, installed and worshipped the lingam(an iconic symbol of Shiva) here to expiate the sin of Brahmahatya incurred while killing Ravana (who was a Brahmin and son of Vishrava). To worship Shiva, Rama directed his trusted lieutenant Hanuman (avatar of Shiva himself) to bring it from Himalayas. Since it took longer to bring the lingam, Sita built a lingam made of sand from the nearby seashore, which is also believed to be the one in the sanctum of the temple. This account is well supported by the original Ramayana authored by Valmiki where it is written in Yudha Kanda. According to another version, as quoted in "Adhyatma Ramayana", Rama installed the lingam before the construction of the bridge to Lanka.


title: Ramanathaswamy Temple

text: The temple in its current form is believed to have been built during the 17th century, while Fergusson believes the small vimana in the west corridor belongs to the 11th or 12th century. The temple is said to have been sanctioned for construction by King Kizhavan Sethupathi or Raghunatha Kilavan. The contribution of the Jaffna kings of Pandya Dynasty to the temple was considerable. King Jeyaveera Cinkaiariyan (1380–1410 CE) shipped stone blocks from Koneswaram temple, Trincomalee to renovate the temple's sanctum sanctorum. Jeyaveera Cinkaiariyan's successor Gunaveera Cinkaiariyan (Pararacacekaran V), a trustee at Rameswaram who also oversaw structural development of this temple and the promotion of Saivite beliefs donated part of his revenue to Koneswaram. Especially to be remembered are the immense sums that were spent during the tenure of Pradani Muthirulappa Pillai towards the restoration of the Pagodas which were falling into ruins and the splendid Chockattan Mantapam or the cloistered precincts of the temple at Rameswaram that he finally completed. The rulers of Sri Lanka also contributed to the temple; Parakrama Bahu (1153–1186 CE) was involved in the construction of the sanctum sanctorum of the temple. Also, Sri Lankan king Nissanka Malla, contributed to the temple's development by making donations and sending workers.

text: Pappakudi a village was donated as a grant to Rameshwaram Temple and one Deva Venkala Perumal Ramanathar in (1667 CE) by Perumal Servaikaran Son of Sokkappan Servaikarar who belongs to Pandiyur. They are local Chieftain under Tirumalai Regunatha Sethupathy Thevar Rein in Ramnad Kingdom. The grant details are published by Government Press, Madras Presidency for Archeological Survey of India in 1885. Along with Pappakudi, Anandur and Urasur villages are also donated to Rameshwaram Temple. These Villages falls under Melaimakani Seermai province of Radhanallur Division.


title: Ramanathaswamy Temple

text: The temple is one of the most famous pilgrimage sites and has several historical references about it. The Maratha kings who ruled Thanjavur established "chatrams" or rest houses throughout Mayiladuthurai and Rameswaram between 1745 and 1837 CE and donated them to the temple.


title: Ramanathaswamy Temple

text: The primary deity of the temple is Ramanathaswamy (Shiva) in the form of "lingam". There are two lingams inside the sanctum - one built by Rama, from sand, residing as the main deity, Ramalingam and the one brought by Hanuman from Kailash called Vishwalingam. Rama instructed that the Vishwalingam should be worshipped first since it was brought by Hanuman - the tradition continues even today.


title: Ramanathaswamy Temple

text: Like all ancient temples in South India, there is a high compound wall (madil) on all four sides of the temple premises measuring about 865 feet furlong from east to west and one furlong of 657 feet from north to south with huge towers (Gopurams) to the east and the west and finished gate towers to the north and south. The temple has striking long corridors in its interior, running between huge colonnades on platforms above five feet high.


title: Ramanathaswamy Temple

text: The second corridor is formed by sandstone pillars, beams, and ceiling. The junction of the third corridor on the west and the paved way leading from the western gopuram to the Setumadhava shrine forms a unique structure in the form of a chess board, popularly known as Chokkattan Madapam, where the Utsava deities are adorned and kept during the Vasanthotsavam (Spring festival) and on the 6th day festival in Adi (July–August) and Masi (February–March) conducted by the Sethupathi of Ramnad.


title: Ramanathaswamy Temple

text: The outer set of corridors is reputed to be the longest in the world, measuring about 6.9 m in height, 400 feet each in the east and west and about 640 feet in the north and the south. The inner corridors are about 224 feet each in the east and the west and about 352 feet each in the north and the south. Their width varies from 15.5 feet to 17 feet in the east and west about 172 feet on the north and south with width varying 14.5 feet to 17 feet. The total length of these corridors is thus 3850 feet. There are about 1212 pillars in the outer corridor. Their height is about 30 feet from the floor to the center of the roof. The main tower or "rajagopuram" is 53 m tall. Most pillars are carved with individual compositions.


title: Ramanathaswamy Temple

text: At the beginning, Ramanathaswamy Temple was a thatched shed. The present structure was the work of many individuals spread over a number of centuries. The pride of place in the establishment of the Temple goes to the Setupatis of Ramanathapuram. In the seventeenth century, Dalavai Setupati built a portion of the main eastern Gopuram. In the late eighteenth century, the world-famous third corridor was constructed by Muthuramalinga Setupati who lived for forty-nine years and ruled between 1763 and 1795. The corridor was called "Chokkatan Mandapam". The Mukhya Pradhani (Chief Minister) was Muthuirullappa Pillai and the Chinna Pradhani (Deputy Chief Minister) was Krishna Iyengar. The Setupati's statue and those of his two "Pradhanis" (ministers) can be seen at the western entrance to the third corridor.

text: The composite columns of Virabhadra holding sword and horn are found be additions of the Vijayanayagara kings during the early 1500s. Similar columns of Virabhadra are found in Adikesava Perumal Temple at Thiruvattaru, Meenakshi Temple at Madurai, Nellaiappar Temple at Tirunelveli, Kasi Viswanathar temple at Tenkasi, Krishnapuram Venkatachalapathy temple, Soundararajaperumal temple at Thadikombu, Srivilliputhur Andal temple, Srivaikuntanathan Permual temple at Srivaikuntam, Avudayarkovil, Vaishnava Nambi and Thirukurungudivalli Nachiar temple at Thirukkurungudi.


title: Ramanathaswamy Temple

text: There are separate shrines for Ramanathaswamy and his consort goddess Parvathavardhini separated by a corridor. There are separate shrines for the goddess Vishalakshi, the "utsava" images, "sayanagriha", Vishnu and Ganesha. The samadhi of the great Yogi Patanjali is said to be at this temple and there is a separate shrine for him here. There are various halls inside the temple, namely Anuppu Mandapam, Sukravara Mandapam, Setupati Mandapam, Kalyana Mandapam, and Nandi Mandapam.

text: There are sixty-four Tīrthas (holy water bodies) in and around the island of Rameswaram, Tamil Nadu, India. According to Skānda Purāṇa, twenty-four of them are important. Bathing in these Tīrthas is a major aspect of the pilgrimage to Rameswaram and is considered equivalent to penance. Twenty-two of the Tīrthas are within the Rāmanāthasvāmī Temple. The number 22 indicates the 22 arrows in Rama's quiver. The first and major one is called Agni Theertham, the sea (Bay of Bengal).


title: Ramanathaswamy Temple

text: Rameswaram is one of the few temples that has the distinction of being the stala, Murthy, Theertham. Ramanathaswamy Temple Theertham is very special. There are 22 theerthams in the form of a pond and a well. These 22 theerthams represent the 22 arrows of Sri Rama.


title: Ramanathaswamy Temple

text: The temple is one of the holiest Hindu "Char Dham" (four divine sites) sites comprising Badrinath, Puri, Dwarka and Rameshwaram. Though the origins are not clearly known, the Advaita school of Hinduism established by Sankaracharya, who created Hindu monastic institutions across India, attributes the origin of Char Dham to the seer. The four monasteries lie across the four corners of India and their attendant temples are Badrinath Temple at Badrinath in the North, Jagannath Temple at Puri in the East, Dwarakadheesh Temple at Dwarka in the West and Ramanathaswamy Temple at Rameswaram in the South. The temples are revered by the various spiritual traditions of Hinduism, such as Saivism and Vaishnavism. The Char Dham pilgrimage is an all Hindu affair. There are four abodes in the Himalayas called Chota Char Dham ("Chota" meaning small): Badrinath, Kedarnath, Gangotri and Yamunotri - all of these lie at the foothills of Himalayas. The name "Chota" was added during the mid of 20th century to differentiate the original Char Dhams. The journey across the four cardinal points in India is considered sacred by Hindus who aspire to visit these temples once in their lifetime. Traditionally the trip starts at the eastern end from Puri, proceeding in clockwise direction in a manner typically followed for circumambulation in Hindu temples.

text: As per Shiv Mahapuran, once Brahma (the Hindu God of creation) and Vishnu (the Hindu God of saving) had an argument in terms of supremacy of creation. To test them, Shiva pierced the three worlds as a huge endless pillar of light, the "jyotirlinga". Vishnu and Brahma split their ways to downwards and upwards respectively to find the end of the light in either directions. Brahma lied that he found out the end, while Vishnu conceded his defeat. Shiva appeared as a second pillar of light and cursed Brahma that he would have no place in ceremonies while Vishnu would be worshipped till the end of eternity. The "jyotirlinga" is the supreme partless reality, out of which Shiva partly appears. The "jyothirlinga" shrines, thus are places where Shiva appeared as a fiery column of light. Originally, there were believed to be 64 "jyothirlingas" of which 12 are considered to be very auspicious and holy. Each of the twelve "jyothirlinga" sites take the name of the presiding deity - each considered a different manifestation of Shiva. At all these sites, the primary image is the "lingam" representing the "Stambha" pillar, symbolizing the infinite nature of Shiva (without beginning or end). The twelve "jyothirlinga" are Somnath in Gujarat, Mallikarjuna at Srisailam in Andhra Pradesh, Mahakaleswar at Ujjain in Madhya Pradesh, Omkareshwar in Madhya Pradesh, Kedarnath in Himalayas, Bhimashankar in Maharashtra, Viswanath at Varanasi in Uttar Pradesh, Triambakeshwar in Maharashtra, Vaidyanath at Deoghar in Jharkhand, Nageswar at Dwarka in Gujarat, Rameshwar at Rameswaram in Tamil Nadu and Grishneshwar at Aurangabad, Maharashtra. The temple is the southernmost of all the twelve Jyothirlingas.

text: The temple priests are Marathi Brahmins of Maharashtra who get "Diksha" from Sringeri Mutt. A shortage of priests has been reported in recent years as there are only five priests to manage the 13 shrines within the temple. The shortage is more pronounced during the 12-day Maha Shivaratri festival when the festival deities of the temple are taken in procession.
