Mathematical R.F. Notes Georgy from Café


There is something about mathematics that is logical and perfectly balanced. The powerful new novella his R.F. Georgy argues that we have all become number four. That is to say, the very idea of ​​progress based on rational and measurable. In one of the most powerful quotes his (this book is full of memorable quotes, Georgy says, “You believe in progress. You believe in the perfectibility of man. You believe in rational ranking people. You believe in Crystal Palace. You believe in … wait , no Worship number four. “What Georgy means by worshiping the number four is that we live in an age of science, which has succeeded in stripping us from irrational character, he rejects utopia we have built an illusion and that our true nature is irrational . Let’s consider the digital age in a minute. According to Georgy, “Information paint, no picture, sing no song, and do not write poetry.” In one powerful reference, Georgy uses a different mathematical analogy to describe us, “We are unfortunate zero is in the denominator of the fraction. We are undefined, the most unfortunate occurrence, give I unto you. “

There is this big metaphor that is the heart of both Dostoevsky and arguments Georgy is against the idea of ​​progress. The rational arrangement of people expected that we can all been molded in the image of science. There is something both disturbing and unsettling about the mathematical analogy Georgy is. Just as zero is forever undefined is placed in the denomination of the offense, our existence is also undefined. We are ontology puzzle and despite all our efforts to get this existential wall, we are always met with silence. Here is a sad irony; we construct the perfect knowledge domain, both the balance and common sense, and yet we are irrational. creatures. It is perhaps this absurdity of our existence that drives us to look perpetually answer. Unfortunately, the answers are not forthcoming.

What is Georgy do with the indefinite nature of our? He uses it less science for answers to what we will not come conveniently packaged for our consumption. It is t say, science is not the intellectual authority it wants to believe. As Shakespeare reminds

. “There are more things in heaven and earth, Horatio, than are dreamed of in the philosophy”

Notes from Cafe is a powerful indictment against science, technology, progress, and the basis of the information. This book should be assigned the reading of all the questions the idea of ​​progress that we all so close.


Mental Math Practice Worksheets


Today, we all know the importance of learning and wondered mathematics. And every time we visit our children’s schools we see Chinese and Indian students honored SATS. And we all know why they succeed in engineering and medical fields. The answer is quite simple, they are good at math. But why are they so good? How did they learn math that makes them so good at that one arduous subject?

When we go to meetings teachers are told by teachers, the wonders of mathematics one must practice, practice and practice. But what if the child loses interest to practice math? We have all had our share experience monotonous tedious task of memorizing times tables. And after so many years, the same is repeated with teachers everywhere, except, Asia. What do these Asians (Chinese, Japanese, Indians, etc.) do to make their children so good with math? The answer is quite simple, practice, practice and practice. But what is it that these students actually practice?

Recently Abacus math has taken some of these Asian nations by storm. Abacus is a Latin word that has its origins in the Greek words ABAX or abakon (which means “table” or “table”), which then possibly originated from the Semitic word ABQ, which means “sand”. The Abacus is a tool, manual tool invented by the Chinese 2,000 years ago. Over the past five years, countries like Malaysia, Taiwan and India, countless tutoring centers like Sylvan, Huntington and Kumon have sprung up but with one goal in mind, a teacher Abacus math. Most of these centers offer training with Japanese “Soroba abacus”, which has one of the upper row of beads and four lower rows. The Soroba Abacus is particularly effective for teaching calculation skills to young children.

Use of the abacus, a child can do all arithmetic calculations up to 10 digits and learn the skills to do it mentally, without relying on modern devices such as calculators.

There are techniques and training methods to master abacus use. When children use both hands to move the beads for small and large numbers of calculations, quick communication between the hands and the brain not only stimulates brain cells to promote faster and faster calculation capability but also promotes quick, balanced healthy brain development.

Now that you know what are all the benefits of learning abacus math – let’s continue talking about practice math. Every textbook comes with some problems of practice and we feel always that some problems are not enough. We want more practice problems for our children and students. The next best option is to find a math practice worksheets. There are many websites that offer you download able practice worksheets for a small fee. And there are several websites that offer you free. Some offer you defined sheets where very few websites offer you to build your own math practice worksheets.

Using math practice sheets early can instill much routine enjoy math and at the same time help to strengthen mental math skills. And using these blades to perform Abacus mental math is absolute fun for the child.


Have fun with math wizard games


Magic has always been part of a child’s life and a math wizard game will surely do the trick if you want your child to have fun with math. Math wizard game will amaze children and will surely grab their attention without them knowing that they are already applied and practice math ideas.

Here is a mathematical trick that is 100% guaranteed will truly amazed children and adults alike without the use of props such as pencils or paper.

  1. Ask the audience to choose a number between 1 and 20 and keep it for themselves.
  2. Ask them to double the number they have chosen again in their minds only.
  3. Ask them to add 10 to conclusion No. 2.
  4. Ask them to divide the result by 2. No. 3
  5. Ask them to reduce the original number chosen because the No. 4
  6. Then you can announce the final result for all should be 5

Look at how fear they will all be and they will surely have a hard time figuring out how you got it all. You can also do some mathematical card tricks that can also amaze kids and impress them with a very simple mathematical magic.

  1. shuffle a deck of cards several times. You can also allow the children to cut and shuffle the cards as often as they want.
  2. Spread out the cards so that everyone will see that it is normal and standard deck.
  3. After some shuffling and cutting You are now ready to lay 27 cards face up arranged in 3 columns 9 cards each. Start by laying out the first 3 cards especially the next 3 cards in the second row until you reach the 9 series. The remaining cards are not required from hereon.
  4. Ask your child to choose a card from 27 cards laid out on the table, but he / she should just tell you which column of his / her chosen card without telling you, the selected card.
  5. After you have been notified of the column in which the selected card is to collect cards with the column from top to bottom to ensure that you collect the column in which the selected card is the second session. This makes the first card column in which the selected card is a 10 card in a 27-card deck you are using.
  6. Without re-shuffle the cards, lay out 27 cards in the same way as before in 3 columns of 9 rows each of them back to ask the child to his column / choose its card earlier is now located. Again collect cards in the same manner as in # 5 above.
  7. Do # 6 and # 5 for the third time and when you finally lay down the cards 4 hours, silently count to 14 map and ask the child if there is a card that he / she has chosen.
  8. Simple math but for kids it’s magic!


Reduce your electric bill


Reduce electricity bill through devices specialization. Most people in the western world have any number of specialty devices. Simple things like toaster, your basic microwave, counter top grill (like a George Foreman grill), toaster oven, crock pot and pressure cooker grandmother to more advanced (or more expensive) things like your rice maker, bread machine, counter top induction cook top hotplate and convection microwave.

There are more than the focus of this article I’ll stick with the kitchen. I the pressure cooker (even though it is not the instrument) for efficiency enhancing characteristics strap dinosaur cook stove. I use the term “dinosaur” because of archaic characteristics power usage. Yes, I know that there are modern convection / steam oven m / induction cook top stoves that are as effective as it happens, but because they cost $ 4,000.00 range they are out of reach of most people, or more than most folks are willing to spend. In addition to utilizing the surface mentioned devices appropriately nets greater efficiency and you already have most of them tucked away in your closet.

For example, lets take a look at the toaster. Have you ever seen someone making toast in the oven when it is a toaster sitting on the table? So then you have to ask “So, what’s wrong with the toaster?” You get the inevitable answer something like “Oh, it must be cleaned” or “It is not big enough” or “It’s too slow for this multiple doses.” Ok, then lets do the math. The average toaster is valued at about 0.5 kWh and standard oven is valued at about 4.5 kWh. The toaster will lodge 2 slices about 1 minute. The oven will Toast 2 slices in about 3.5 minutes but you may not use the oven for only 2 partitions will base our number 8 slices. Now, the same oven will toast 8 slices in the same time; 3.5 minutes. Check the oven must be pre-heated to about 7 minutes. So now our radiator up to 10.5 minutes. The toaster on the other hand is about 5 minutes for all 8 pieces. Now let’s look at electric use. The oven is 4500w / 60 minutes is equivalent to 75W per minute times 10.5 minutes corresponds to a total of 787.5 watts. My local utility rates close to 10 cents per kWh as the oven is costing us $ 7.88. The toaster is 500W / 60 minutes to level 8333 watts per minute times 5 minutes corresponds to a total of 41.67 watts. So toaster is costing us 42 cents. Just 3 use the oven in this way would pay for a new toaster. I hope I’ve made my point.

I could do in the same place for every kitchen aid above and with a little effort (to reduce kitchen aids under the table) you could save proverbial ton of cash and increased service just has much less green house gas to be released into the atmosphere. If the grid, that is. If you are not on the grid then there is much less stress, wear of wind solar system.


Math and Critical Thinking, Part II


In the previous article I went to tell the story of the unusual high school geometry course look at Ohio State University in 1930. The course has been designed and taught Prof. Harold F. Fawcett later published account of The Proof (NCTM 13 Yearbook reprint 1995). To quote from the book,

There has probably never been a time in the history of American education as the development of critical and reflective thinking is not known as a desirable outcome college.

Given Fawcett is, geometry was the most suitable courses in college to teach critical and reflective thinking. He provides a respectable selection of quotes to support his opinion and to explain the origin of their dissatisfaction with traditional courses. Traditionally

… the main emphasis is placed on the shoulders of the sentence to be learning rather than on method these theorems are established.

As a result,

… there is little evidence to show that students who have studied visible geometry are less gullible, more logical and more decisive in their thinking than those who did not follow such a course.

The worthy outcome for students taking geometry courses is not only true and learn to put the sentence, but the acquisition of intellectual habits of save them from floundering in the implementation of . Not only students should learn the true number sentence, but also to realize character evidence , so that analysis technology can them could be transferred to non-geometric conditions. And how is this done? Fawcett cites prevailing View Point

No transfer will occur unless the material is learned in the course of the field to which the transfer is requested. … Transfer is not automatic. We harvest no more than we saw …

Fawcett concludes that transfer is secured only by training for transport , which explains the unconventional opening his course (see Part I). Next he discusses methods and procedures which are suitable for such a study. His treatment is so much relevant to contemporary debates today (minding its own logic children and unique way, group discussions, open-ended approach, detection and investigation) that attempt Fawcett and the book deserves to be better known among math teachers. The point of the opening of the debate was to assess the need for agreed-upon definitions seemed alien thinking of students . For example, at the beginning of all students agreed that “Abraham Lincoln was very little time in school” and no one raised the point that the truth of this statement depends on how “school” is defined . So, from the first meeting, students were led to recognize the importance of definitions and later needed some unspecified way. They were invited to recognize the existence of the implicit assumptions even in the most elementary activities of life.

Flener interview Warren Mathews, graduate courses. Comments Mathews’ was

I remember all of our work with the definitions. When I was the head of Hughes, and now my work with my church, I realize how important definitions. It is amazing when we can agree on our definitions of the most conflict ends.

As Flener word

In the field of education, the argument probably cross purposes more because we do not have the same definitions in mind.

How true! And how sad! Unless of course math teachers have no special reason to feel singled out in this regard. “In the field of education” should be considered as a generic name.

But let’s try to apply course descriptions basics of the course itself. Is it right to appoint an attempt Fawcett is geometry right ? What makes a school year long interaction between a group of students with one or more teachers a geometry course? Can you think of an appropriate definition?

How does it jibe with comment Fawcett’s [p. 102 of his book]?

Although control geometric content was not one of the main purpose to be accomplished by students of Class A, however, it seemed desirable to compare their achievements in this regard with the students who had followed the normal course geometry.

I think that the description “Critical Thinking Course with applications to geometry” serves the purpose, procedures and results of course Fawcett is. The skill transfer took place in the opposite direction of the stated goal! What experiment shows Fawcett is very convincing to the development of critical thinking helps students learn math, even when they feel no particular taste for the subject.

At the end of the course, Fawcett interview the parents. In view of their parents, of course, helped 16 students improve their ability to think critically, but only three of more than 20 students have learned to like math.

And then what?

In a 1997 article Is Mathematics Necessary? , Underwood Dudley argues that the answer to the question in the title of his paper is sound No . He ends the article with a pun,

is mathematics necessary? No. But it is enough.

This may or may not be so. But in any case, some things seem to be more abundant than others. (A discussion of what mathematics can be enough for, could have fit right in with Fawcett’s geometry course.) We saw just how critical thinking helped to learn math. Flener ties of the success of the course to students who took courses were veterans of the University for three years and was used to open ended research

Following is a more complete quote from the paper Dudley :.

Do you remember why you fell in love with math? It was not, I think, because of its usefulness in managing inventory. Was it not because of joy, a sense of power and the pleasure it gave; the theorems that inspired fear or jubilation or amazement; wonder and glory which I think is the supreme spiritual achievement of mankind is? Mathematics is more important than jobs. It started then it is not them.

Is mathematics necessary? No. But it is enough.

No doubt mathematician Fawcett knew about and could appreciate the splendor and beauty of mathematics. He was an excellent teacher and could, if he would do better things in their students this sense of beauty and wonder shared by all mathematicians. He chose clearly not. His goal was to teach students about relations with mathematics, critical and reflective thinking . But the aims of education are many: the acquisition of useful skills, the absorption of local and international culture, the development of innate potential. Programmes could and should be matched with a variety of objectives. It stands to reason that the way in which mathematics courses are organized and managed should aim at a specific target. There is no one right way to teach and learn math.

Definitions are important. To solve cross discussion purposes, it is also important to accept the possibility that approach can be just as, or as good as another -. Maybe the other end

Top 5 Tips to teach math to kids effectively


Every parent is aware that math skills necessary for their future children. Mathematics will assist in all aspects of life. If Math is a professional in the wrong way, children could possibly get bored easily. Below are the top 5 best tips to teach kids Math really.

1- before teaching Mathematics, be sure they are taught formal logic first. They should be able to think in a logical way with words and the real world conditions before it can be applied to abstract concepts like numbers. Failing in this first step causes children difficult to understand mathematics, and soon makes them hate math. They should be taught how to think first.

2- When thinking about the best ways to teach math kids, age is an important factor to consider first. Make sure the learning unit is appropriate for the age of the kids. Toddlers and preschoolers should learn the basic meaning of the figures, it means to count things. Early elementary school should focus on the numbers, understanding of addition and multiplication tables for one-digit number. When they can master this, move on to algebra, geometry, fractions, fragments, set theory, even calculus, and if possible, introduce the so-called advanced materials as soon as possible. In the early stages of teaching pre-math, they just have to see it, they do not understand it. Your results will be seen later, they will easily absorb and understand the material when they are covered in grades 6-12.

3- use something they can relate to. Try to make it simple and fun. Also to be practical to make them easy to understand. For example, to teach addition or subtraction, use countable food they used to eat. Teaching division or fractions using cake.

4- Create fun and cool Math games for kids. Printable Math board games, card games, print and play game worksheets can be found on the internet.

5- In mathematics needs a lot of recall skills, have a good memory will be a big advantage in our children. Add your kid’s memory by providing him / number of exercises her mental addition or multiplication, recalling explore such as a birthday or anniversary or dates for special occasions and make connections with other events that happened or will happen on a particular day. Working out my kids will truly be an asset later when he needs to memorize rules, recipes, methods or procedures used to solve math problems or equations.


Teach math to kids using these indications


Math has been one of the most important challenges that every child will have a good base with. Unfortunately, many kids nowadays do not show interest in mathematics because they find it boring and hard to understand.

However, the mathematics considered as one of the participants that you will go to continue to the next level of your education. So this problem will be solved and conquered. Here are 5 tips to teach math so that children do not get bored.

1. Age and other things to teach.

Keep in mind that “slow and steady wins the race.” There is no need to rush into it because kids take things fast, but it will also confuse them if they take in information too quickly and do not understand. Be sure that what you are teaching is understandable kid.

2. Use different teaching methods.

Every person has a different learning style. There is no guarantee one way to ensure that everyone understands. So it is important for you to have some teaching. Example: Teach them the way in which they can relate to things around them. Let’s say fragments, you can actually get a pizza and cut it into whatever offense you are teaching. This makes learning a lot more fun.

3. Games.

Kids love to play games. Use games to cultivate their interest in mathematics, it helps. By playing games like board games or online math games, children learn that mathematics can be applied through the game and not only in school. It gives them more meaningful purpose to study mathematics.

4. Remember.

Math relies heavily on recall skills and also mental calculations. For exercising your brain will be very important. Giving food child mental calculation and schedule will help them to improve memory skills.


Understanding Transformers


We must establish some basic principles tension before growing in Transformers. What is the current, voltage or load? Imagine a man hauling a wagon uphill. The voltage (V) is the man (120V). Current (Amps) is how much work he has to do to get up the hill (2amps) and the trailer load (a motor of some sort). Or perhaps the man is a friend create them both (240V) with both of them working together and they do less work (1amp) load stay the same (motor of any kind).

What transformer do? Transformers would lead ignition. They take action and either step down voltage, step voltage up or isolate the tension in one area from another. So why is it so important to manage this tension. Take for example the local power company. It uses a step-up transformer to provide high voltage power lines that creates a low amperage. Then, before entering the home or local companies step voltage back down the voltage coming to is not too high.

What parts make up transformer? A transformer is made up of three parts; The laminated iron core, primary and secondary windings. The primary winding is connected to the power entering the transformer (input voltage). Secondary winding is connected where the power is going to (output voltage). The laminated core is used to separate the primary and rolls from having any physical relationship.

So how transformers work? There are no moving parts of the transformer, instead of using a transformer stimulation to pass power from the primary winding to the secondary winding. An easy way to understand what it uses electromagnetic induction to take the voltage from the primary winding and move it to the secondary winding. We control stimulation with a turn rate.

What is the turn rate? A return rate is the relationship between the primary and the secondary winding. If it was in 120V transformer and 24 volt leave the transformer. Tension us would be stepping down with 5/1 turn rate. Simple math is used to calculate this; voltage coming / leaving voltage transformer. With 120/24 you would have 5/1 ration.

How do you size transformer? You size transformer secondary winding of the transformer. Secondary winding is rated in VA (volt times amperage). An example of this would be to have a 24v control circuit that capacity is 2amps. You would take your tension (24V) and multiply it by the maximum amperage you (2amps) that would be 24 times 2, which corresponds to 48 or 48 Va. This means you would need a transformer ratio 48va.

Do transformers need to be serviced? No, no moving parts there is no maintenance required. When the transformer has been ill, generally show the primary windings, it will need to be replaced. Some transformers come with a CD fuse link or security. If the transformer has been tripped or has gone bad, it is a general rule for a source causing problems. A bad transformer is never a “problem” only symptoms of the real problem.

What are the different types of transformers? There are many types of transformers which you will see in the field; step up, step down, isolated, multi tap and auto transformers. There are also other forms, a three-phase transformer, the transformer became more excitement to enter the commercial building. The general rule is the most common type of transformer you will see is a step-down transformer (ignition).

What is the difference between these types of voltage? Step up Transformers take the primary winding and step up the voltage for the secondary winding. Step Down Transformers take the primary winding and step down the voltage on the secondary winding. Isolation Transformers have the same voltage in the primary and secondary. A multi tap transformer is a step up or down transformer that has multi taps either the primary winding or secondary winding. An autotransformer is a special type of transformer that do not follow the general rules of Transformers. It uses a continuous winding is tapped to provide a step-down or step-up function.

Transformers play a key role in the AC power system. They are a way to control voltage. There is no maintenance required AC power though they are excellent indicators of problems. Understand the terms and rules is the key to troubleshooting and design circuitry.


Mathematical important topic in all fields


When talking about science and commerce sectors, mathematics comes across as the most important ingredient. The research on this subject is necessary to lay a solid foundation for all technical. It basically deals with logic and substitutions. The best thing about the matter is that even if you do not know the next step to solve it, you can still continue to try to get the right answer. The most important thing needed to solve the problem is the aptitude and zeal to solve it. It is interesting to note that the scope for innovation in mathematics is endless. You could snack when you see tough problems while working with to get the right solution to it has its own pleasure. But, to begin with will have a strong base and a clear understanding of mathematical concepts.

There are many people out there who lack the necessary confidence, skills and aptitude to solve complex problems. It is an open secret that no discipline is complete without mathematics, and students need to learn this subject for a better future. If you are unable to get your doubts cleared in class or need extra help with your homework then you have to try various methods. There are many websites that offer free online help with math homework. You can seek help from these sources, but they have both advantages as well as shortcomings.

The advantages are that the sites offer assistance with math homework totally free. You just need to send your complaint online and a professional or expert will provide the solution to it. This can save you from a great mental strain, and is certainly a great help when you have to do complex mathematical tasks. However, it also has some shortcomings. This method is not useful if you’re stuck with some problems and have a test or needed to deliver projects next day. The online sites take time to provide answers to questions and sometimes these solutions may not be enough.

Also, much better and more effective solution would be to hire a private tutor in your locality. Fortunately, it is now possible to find an expert teacher in different issues of mathematics, such as integral, differential calculus, statistics, etc. With the help of math teacher, you would be able to strength base of this material and doing well on all fronts life.
