Every crew gets to design their own patch. In this next scene here, you'll see our patch, which has the entire globe, as well as the sun on it, symbolizing the global nature of looking at atmospheric research and the effect the sun has on the chemistry of our atmosphere. We had the opportunity to launch midday on November 3, which made it a very comfortable wake up for half of our crew, waking up at 7 o'clock in the morning. However, because we were a dual shift flight in conducted operations around the clock, the other three members of the crew had sleep shifted themselves to wake up at 10 o'clock the previous evening. So they'd been awake about 12 hours, or actually 14 hours before we launched. We checked the integrity of our suits, and then we walk out of the ONC building at the Cape to get on the aster van for the 7-mile drive out to the pad. We had a beautiful morning for the launch. The skies were crystal clear, not a cloud in sight. At T minus 6 seconds, the shuttle main engine start sequence began. And moments later, we're on our way to 66th mission of the space shuttle program and the 13th mission of space shuttle Atlantis. We were already over 100 miles an hour as we cleared the tower. And we began our enrollment over to the attitude required for our 57-degree high inclination orbit. Our trajectory actually took us up the eastern seaboard of the United States just off the coast. At this time, the orbiter, well, it left off the orbiter weighed around 4 million pounds, and our thrust was around 7 million pounds. So the thrust to weight was pretty nice. And we were getting out of town in quite a hurry, as you can see. The orbiter was burning about 3,000 pounds of fuel per second. And as that weight decreased, the acceleration increased up to about 3 Gs, or 3 tons, or Earth's gravity. At two-minute sensitive flight, we had expended all the energy out of the solid rocket boosters. So they were jettisoned to be picked up by the recovery ships waiting about 50 miles off the Kennedy coast. It's hard to imagine we sit on the pad and in just a few moments later, we were at orbital speed just under 18,000 miles an hour. And we did all that in 8 minutes and 42 seconds. So you can imagine the ride and the acceleration was quite unbelievable. At main engine cutoff, we went from 3 Gs to almost 0 G instantaneously. It was quite a spectacular sensation. My first job was to film the external tank, which was flying in close formation with us for post-flight analysis before it re-entered the Earth's atmosphere. And one of the first things we do when we get to orbit is open the payload bay doors. And we do that for thermal reasons. But it's also a pretty exciting event for the crew because it gives us our first real view of the Earth from space. The first day was very busy with activation of all the payloads, including the Krista Spa. You see Kurt and Joe in the fourth flight deck controlling the digital autopilot and also keeping the big pitch of all the systems. While on the after flight deck, Ellen is flying the robot arm to grapple the Krista Spa with a special electrical connector to activate the batteries. You see the arm closing to the payload. You can see the target, which is a very important visual cue for the arm operator to center the end effector and the snares around the grapple fixture. Then comes time for the deploy. And starting with the unbirth of the payload, very smoothly to prevent any saturation of the gyros on board the Krista Spa. And then a maneuver from the low hover to the release attitude. You can see the mass antenna moving, scanning the atmosphere. This is quite a long maneuver from the low hover to release attitude. Krista Spa is a composition of the platform Spa and the instrument Krista and Marcy. Krista stands for cryogenic infrared spectrometers and telescope for the atmosphere. And with the three telescopes on board and very high speed sensors, it collects a very high space resolution data of the middle atmosphere. And when we get ready on the orbital side as well as on Krista for release, I check the trigger to open the snares in order to start the release. And you can see now the end effector backing away from the payload. Very nice view of the earth from the background. And when the arm stops at a few feet from the payload done from the aft flight deck, we'll fire the first separation maneuver. And once the deploy is complete, the ground team and the crew on board is very happy with a successful deploy. Here's a view of the payload base showing the atmospheric and solar science instruments. The main structure that you see is the space lap pallet with the six Atlas instruments on board, as well as a lot of the support equipment. This is a close-up of some of the solar instruments. And you see the door opening on Solcon, which measures the amount of energy coming from the sun. And this is another view of the payload bay taken from the camera that's on the elbow joint of the robotic arm. Here's a view of SSBUV, an ozone measuring instrument as the door opens. And it begins to measure the back-skettered ultraviolet light from the Earth, which will allow it to measure ozone. This is the escape payload, a solar physics experiment sponsored by the University of Colorado. And it took advantage of four solar viewing periods throughout the flight. This is the assembly of one of the biggest secondary payload in the mid-deck heat pipe performance experiment dedicated to testing heat pipes extensively used on both automatic satellites to cool electronics. And then is currently running a spin test where pipes are spinning to see how centrifugal force prevents the heat pipe to work properly. And we could set the power as well as the spin rate. We had also a PGAC to help collecting data. This is the protein crystal growth experiment. We had two on board. And we've been told that we had the highest yield of some of the highest quality protein crystals they've ever seen since protein crystal growth experiments have flown on the shuttle. And the crystals will ultimately be used to determine their three-dimensional structure and ultimately lead to better pharmaceutical development. And this is a close-up of one of the chambers showing some beautiful, very large protein crystals. Three gold boxes that you'll see in the frame here on the locker doors were the accelerometer for the shuttle acceleration monitoring system, SAMS. And we used that equipment to document the microgravity environment on the orbiter. This is a piece of equipment called Albert that Jean Francois and I used to position ourselves when we were operating the robotic arm for the deploy and the retrieve. Our galley was the focal point of life on orbit. We hydrate some of our food with hot or cold water, as indicated on the package. Then we cut the package open and eat the food with a spoon. Even after all those years of being told not to play with your food, when eating in space, it's almost too much fun to resist. Jean Francois invented a new dish, shrimp cocktail on a tortilla. I think building the shrimp fajita was half the fun. Of course, eating it was pretty good, too. We had plenty of cameras on board to document not only our in-cabin activities, but also the extensive Earth Obs potential we had on our 57-degree inclination flight. We took over 6,000 frames of film on our 11-day mission. And it's a great opportunity to see the world without boundaries and also to get a better feel for meteorology, oceanography, and geology. This is a tremendous view of plate tectonics in action. This is the Indian plate meeting Asia arising in the Himalaya Range. And in the foreground, you can see the Ganges River here, several of its tributaries and alluvial fans that feed into the Ganges and the foothills to the Himalaya Range. And this is literally the roof of the world. There are several 8,000-meter peaks in this field of view here, including Mount Everest and Annapurna, just a gorgeous site that the blue shift had a chance to see on several passes. Up at the top of the field here is Bowtie Lake, one of the landmarks that we used to identify Mount Everest as we go by. And now in the field is the Tibetan Highland. It's a very arid land with a mean altitude of 14,000 feet above sea level. This is a beautiful scene of the Great Barrier Reef off the northeast coast of Australia. You can see the coral formations, the different color of water indicating different depths, several plankton blooms and the ocean currents in the sun glint to the right. We had the opportunity to see several major storms while we were on orbit. This one was Hurricane Florence that occurred early in our flight. We had the opportunity to pass by and zoom in on the eye of the hurricane. You can see a very well-defined wall. We had the opportunity to exercise almost every day on orbit, and here you can see Jean-François enjoying the exercise, the music, and the view. It was pretty spectacular to do that. This is a view of the Interlim Resistance Device, an exercise device that I developed when I was out at Ames with one of my colleagues there. And it allows us to exercise all of our anti-gravity muscles while we're in space with minimal impact to the orbiter. In addition, it allows us to preserve some of our neuromuscular coordination when we return back home. We can also reconfigure for upper-body exercises. During our half-day off, we had a chance to play with zero gravity, and perhaps my drill instructor from officer school would be impressed with this maneuver. Another big challenge during our little free time on orbit was with Scott and I trying to, around the two big bubbles of water together, and we managed to do that, although it's very difficult to handle this soft, big bubble in the mid-deck.  This is me being attacked by the morning mail messages from Mission Control today. We are frequently asked how we sleep in space, and though on different shifts here, the three rookies are demonstrating the use of our sleep stations. We had a peculiar phenomenon occur during one of our supply water dumps. We dump water overboard that's either not needed for cooling or consumption by the crew. You can see in the upper left corner here is the supply water dump nozzle with a stream of water coming out. What's building here is an icicle that formed on the outside of the cargo bay door, which is off the picture to the right. And the icicle formed and would have continued formation probably right up to the dump nozzle had we not stopped the dump at about this time. Now watch the plug here. This is a look at the entire icicle after it had formed about six feet long off the payload bay door and that part of that ice remained all the way through the entry until post landing. It was still on the vehicle. Here we have the flight deck crew down myself and Joe preparing to do a procedure called flight control check out where we crank up one of the auxiliary power units for hydraulics and we move all the flight controls and check all the implementation and displays out for our trip home make sure Alanis is ready to come home. Standard procedure we do every mission. And after eight days of free flight it was time to join back up the spas to bring it home. It is a beautiful sight here against the deep lack of space. Kurt monitored the rendezvous and performed the final burns from the left sea while I managed the various sensors used to display our approach on a portable computer. Don flew the final stages from the AF station taking inputs from us and the computer program but ultimately using the best sensors we had on board is very on eyes. We worked our way in until we had and we could see every detail of the surface of the Krista spas finally for the grapple. Jean Francois operated the handheld laser and gave Don and Kurt very accurate range and range rate measurements that allowed us to make our rendezvous time almost down to the second. Here's a little closer view of Krista spas as Don is flying the final part of the approach and I'm getting ready to use the robotic arm to do the capture. And this is a view of the arm as it's coming in over the grapple pin and then I initiate the capture sequence which pulls the payload onto the arm and rigidizes it. Here's a view after we've captured it and before we've birthed it in the payload bay looking out the overhead windows and the rendezvous was accomplished on flight day 10. On flight day 11 we went into our final solar viewing attitude, the last opportunity for the solar instruments to take measurements and then flight day 12 was our day to come home and this is us preparing to come home and one of the last things we do is close the payload bay door. Well once we have the payload bay doors closed it's time to reconfigure Atlantis for the trip home. We get back in our orange pumpkin suits and we prepare for the burn. We use our engines to slow the orbiter back down to reenter the atmosphere. It's time to turn some of that kinetic energy we gained during launch back into heat and Joe's pointing out the windows so John Francois takes a look and you can see the plasma behind us as we stream through the atmosphere converting that energy back into heat. Out my right window here you can see the glow around the orbiter also as we're penetrating the atmosphere. Don's managing the energy, make sure we have good energy state and here's a long range camera from Edwards picking up our yaw jet, thrusters still firing to maintain attitude. This is a lookout Kurt's right window there as we make about a 90 degree turn to final at Edwards. As we roll out on final we had one final test to perform before we landed. It was a subsonic aero test to roll the vehicle left and right and to yaw the vehicle left and right to look at control power in those control surfaces to see if there's a potential for more crosswind capability in the vehicle. Once that was complete we rolled ourselves back out on final approach. We fly the approach now at about 300 knots equivalent airspeed at 2000 feet or so we begin to decrease our glide angle from 20 degrees to just over one degree. At 300 feet Kurt extended the gear for us and as we continually decelerate we cross the threshold of the runway at about 225 knots, 17 feet in the air and targeting a touchdown speed of 195 knots. We touched down about 3200 feet down the runway and immediately after touchdown we deployed drag chute. We had the first reusable drag chute of the space shuttle program. The drag chute helps us decelerate as well as lowers the slapdown rates on the nose gear. The deceleration we get out of the drag chute reduces the amount of runway we use by about 1500 to 2000 feet. At about 60 knots we release the drag chute so we don't have to contend with that hardware post wheel stop. And by this time we had flown about 175 revolutions of the earth and we'd been in space almost 11 days and flown four and a half million miles.  No shuttle presentation would be complete without a shot of our launch. It's a very exciting beginning to the mission and this is a view from the base of pad 39 Bravo at basically sea level. And just a few seconds after your orbit has lifted off. Again we had a beautiful day that day, crystal clear blue skies. I don't think I've ever seen it in your blower and it was quite an ascent. A few days later however we had another chance to look at pad 39 Bravo from a different perspective from about 165 miles directly overhead. And you probably recognize most of the things here in the slide we have this pad right here is 39 Bravo where we left off or did our lift off and you can see the Southern pad and also the Corolla track where we maneuvered the orbiter from the vertical assembly building and the orbiter processing facility here out to the pads. The shuttle landing facility is right in here as we see. And if you take a bigger view you can see down here the skid strip at Cape Cronaveral complex and also the beginning of our space program, the very historic pads we have here for the Mercury and the Gemini program along with some of our expendable pads that we used to launch the expendable payloads or expendable rockets I should say into orbit. Cape Cronaveral seaport is down here and if you come on find Cocoa Beach down to Patrick Air Force bases here on up through Cocoa and we have Titusville Airport and Titusville up in here. So it's quite a view again very clear for Florida and this is where we're supposed to land November 14th obviously Tropical Storm Gordon had other plans so we wound up in Edwards. Here's another view of our payload bay and I wanted to point out some of the instruments that we were carrying on board. We had three atmospheric instruments, two of them on the Atlas Pallet. One of them here, Atmos and then you can see the Mars antenna over here and up here on the starboard sill, the SSBUV instrument. All three of those instruments measure ozone and one of the exciting results was to compare the ozone measurements between all three instruments which we were able to do in some of the Northern Hemisphere measurements. Atmos and SSBUV were also of course focusing on the Antarctic ozone hole which was present during our flight and was just beginning to recover and they were measuring the ozone within the hole at about half the level of the ozone outside the Antarctic ozone hole. Atmos also measures about three dozen other trace molecules in the atmosphere to get a much more complete picture of how the ozone depletion process occurs. It measures chlorine which is the primary catalyst for ozone depletion and a lot of the reactive nitrogen species which combined with chlorine prevented from depleting ozone and we were able to get to what the concentrations of those chemicals were as a function of altitude both within the hole and outside the hole and they also found that chlorine exists in different reservoir species at different altitudes which was a new and interesting result for the scientists. They also measure, Atmos also measured in the mid-latitudes one of the Freons, Freon 22 at a value that had doubled over the measurement that it took in 1985 and we really still don't know the significance of what that might be. Some of the solar science instruments, there's three solar science instruments in the center of the palette, ACR, Solcon and Solspec and there's one on the far side of the palette that's hidden from view called SUSM. Two of those measure the total amount of energy coming from the sun and they were very pleased with their results. They were able to get measurements with a precision of less than 0.05%. The other two measure the solar spectrum as a function of wavelength and along with SSBUV three of them independently measured the ultraviolet solar spectrum which is a difficult measurement to make because ultraviolet light affects the optics of the instruments so they were very pleased at that result and the final instrument on board is way in the back and you can just barely see the door open behind the atmos, that's the escape instrument and it's a solar physics experiment looking at the sun in the extreme ultraviolet wavelength region. This is our other primary payload you've seen in some of the other shots of Krista Spa satellite and Krista is the main instrument that you see here, the big white cylinder and it's cooled by cryogenic helium which is what takes up a lot of that space there. Krista's primary objective is to understand more about whether in the stratosphere or the middle atmosphere. Of course we're all familiar with weather in the troposphere which is what we experience every day but there are a lot of phenomena that are very similar in the middle atmosphere, winds, turbulence, large temperature changes and not very much is known about that and by measuring different chemicals that can act as tracers they hope to understand quite a bit more about that as they go through their data. They're also producing the first global map of atomic oxygen in our atmosphere which scientists think help cool the earth. The other primary instrument, Marci, is sitting right here under these insulating blankets and it was measuring hydroxyl and nitric oxide which are two important chemicals in the ozone depletion process. We had, as I mentioned, an opportunity to see three different storms. One of them was a super cyclone Zelda that was out in the Pacific. We also saw a tropical storm. Gordon developed off the coast of the Yucatan which eventually became a hurricane and caused some pretty heavy rains in Florida and severe damage. Gordon was also one of the reasons, obviously, that we did not land at the Kennedy Space Center because it was affecting the peninsula at that time. This is, again, a hurricane Florence which developed southeast of Bermuda. It eventually moved north and became extra tropical and never reached landfall as a hurricane but the moisture from this storm combined with a storm over Europe and caused some fairly severe flooding over France and Spain. This is the part of the Indonesia chain looking from the north to the south. The large island here of Java is present as well as the islands of Bali here and Lombok. On Bali and Lombok, there were some fairly severe eruptions of volcanoes in the summer of 1993. There are two volcanoes on Java that are venting steam right now. One of them is Arjuno which is near the center of the screen and it's difficult to see the venting that's occurring. Also over on the right side of the screen which is difficult to see here is Maripai. Maripai, three weeks after this photograph was taken, had a major eruption which caused some fairly deadly mudslides to occur on the island of Java. This is the Ganges River Delta, the largest delta in the world. This photograph is centered on the country of Bangladesh and what you can see here at the base is massive amounts of silt and clay sediment originating from the Ganges and Brahmaputra rivers far upstream. It's an ecological area of key importance because all of this is mangrove habitat. It's an area where many aquatic and landforms live. Notably in the remaining forested mangroves here at the bottom of the view, the Asian tiger resides. Unfortunately, other pressures have caused a significant amount of deforestation and movement towards converting mangroves into rice paddies. So the shuttle photography helps scientists document the rate of environmental change as well as geologic change, including delta growth because of all the sediments coming from the rivers upstream. This is a gorgeous shot of the highest mountain in the world. This is the summit of Mount Everest. It stands at 8,848 meters or for those of you who aren't metric, it's 29,000 feet and change. It is an area of special significance for me because had I not been selected as an astronaut two years ago, I would have been on a climbing expedition and probably or hopefully would have been standing on the summit as my STS-66 compatriots flew overhead. And this is a tremendous synoptic view, a low oblique of the region that we've just been talking about. Often the distance here you can see the beginnings of the Ganges River Delta. You can see the foothills of the Himalaya, the roof of the world, and the Tibetan Plateau. In this view you can see Boatai Lake which we pointed out in our movie. You can also see the Everest region and the Annapurna region. You can see several tributaries and alluvial fans feeding the Ganges River. And this view really demonstrates the rain shadow effect. And what I mean by that is warm, moist air emanating from the Indian Ocean meets the Himalaya and as that air rises it drops all of its moisture in the form of precipitation. And so we have green lowlands and very snowy high peaks but very arid territory over here. Well one of the more nice places or the neat places take photos from orbit is the Middle East because it's always clear hardly ever a cloud in the sky. And what we're looking at here is the Sinai Peninsula pretty much in the center of the frame with Egypt and Africa to the top and the land form here that we see. We take photos from orbit for many different reasons. A lot of them are taken just due to the sheer beauty. However we do take a lot to study the earth. Geology is a major issue, meteorology, how humans are affecting the climate and how they're using the land. So to give you an example, this slide has a lot of those issues in it. The Dead Sea Fault right here with the Dead Sea sitting here is the lowest place in the world over 300 meters below sea level. Everything flows in there pretty much nothing flows out obviously at that sea level. It represents the geology that we look for. From space we can see the big picture of how different plates of the planet are moving around and tearing apart and we've been studying that in a lot of different areas of the world. Vegetation and how we use the land, the little vegetation streak you see right here separates Egypt to the south from the Gaza Strip and also you look right in this area is the river Nile Delta where it's highly cultivated and the ribbon of the Nile which is very historic both in religion and history as it flows or comes from Southern Africa there. Again, we can study these areas using color visual photos like this one or color infrared which you'll see here in a few moments and we can understand how the inhabitants are using that land whether they're over using it or under using it, how the irrigation and water system is working. Also meteorology from this slide, if you look down in the left part here you can see basically streaks caused by high winds and sand dunes and different materials moving around. Another example of this is Western Africa over in here we wind up seeing a lot of sand and material blowing off the Western Deserts of Africa in the same systems that bring us to hurricanes across the Atlantic to Central America and to the United States area. We have documented results that show material maybe off your car in the mornings of sand and dust that has really come from the African continent and has just been carried in the upper level winds halfway around the world. Another photo here showing the effects of humans on the environment. This is the Okavanga River Delta in Northern Botswana which is in the southern tip of Africa. It's an inland delta, it's kind of unique in that the river flows into this delta. Usually we think of deltas being into the ocean like New Orleans, but this is an inland delta. Heavy rains and wetlands in northern or in Angola flow down the river and enter the delta at this point and due to a bunch of faults and rifts, again geology-wise, causes the river to dam up and perform this inland delta. The size of the delta is kind of unbelievable from here to the tip of it down here where it enters the Kalahari Desert is about 95 miles long and it takes over six months from the water to move from this area to maybe the tip of the delta. During that time it's absorbed used by the plant life or evaporated and some of the civilizations around there are trying to pump water out of this area to mining operations in the cities, again which will destroy this area which is very similar to the South American rainforest. It is one of the more wilder regions of the African continent. Huge herds of buffalo, elephant and zebras and other animals roam there quite often. We photograph this area almost every shuttle flight if we can to help document the changes in this delta because it's kind of a miniature model of how other areas of the world are working. A lot of times in these areas up here we see fires where people are burning off the wetlands so they can use the area for grazing since cattle herding and cattle is the biggest industry for the local population. And over the past 100 years we've documented the changes in this river delta, how different weather phenomenon and how humans are affecting it and it's slowly shrinking and going away. This is an oblique view of Lake Chad. Lake Chad is located at the border of Chad, Nigeria, Nigeria and Cameroon. It's also a very good subject for photography on each shuttle flight as it is a very shallow lake less than 25 feet deep and that's why the size varies seasonally very much. The picture shows the water on the southern basin. The picture is looking south. We have the water on the south basin and you can see also very big dunes covering the eastern and the northern edges of the lake where water used to stand before. And also can be seen the prevailing wind direction very easily with the agricultural burning blowing to the west. This near vertical false color infrared picture shows a very unique agricultural pattern in the south of Khartoum between the white and the blue Nile rivers. Of course it seems right, that's why everything green looks red on the picture. Hundreds of rectangular fields can be seen over a size of about 100 miles and also straight lines that are the water field canals irrigating this region. This is by very far the biggest irrigation project in North Africa. In a periodic cycle throughout the year half of the fields are in crops essentially of Khartoum and the other half is fallow for resting soil and also for pest control. This is also an oblique view of the straight of Gibraltar looking southeast. Mediterranean Sea is on the upper left corner and you have the Atlantic Ocean on the right. This is Africa on the top and Spain on the left. The sand glint highlights very much the high currents through the strait and also current shears along those straight lines starting from the coast of Spain. Also we can see very easily surface waters patterns thanks to the glint and also some very small shipwigs. The sand glint highlights also the town of Tangier here in Morocco, Africa and also the Bay of Cadiz in Spain. Also you can see very long contriers on the bottom of the picture. This is a nice oblique view looking northeast of the whole Alps Mountains chain which is a natural border of binding the some of the main European Space Agency countries participating in the International Space Station program. France on the left, Italy on the right, Germany on the upper right corner and Switzerland in the middle. Can be seen very easily the pattern of the Rhone Valley with the famous curve the inverted L shape and a 90 degrees angle here leading to the Geneva Lake and also it's very easy to see those big valleys here on the Italian side as they have been shaped as a U letter by a glaciers during the last Ice Age. This is the Aosta Valley and this is a valley leading to Turin and here you see the Isère and Morien where a lot of very famous French and Italian skiing resorts are located. This is a view of Greenland because of the time of day that we launched we had sunrises usually in the very southern part of our orbit and then we had sunlit as we ascended in our orbit and had sun sets at the top of our orbit. So this is kind of a late afternoon shot and of course it's easy to pick out all the fjords along the coastlines which were created during the last great Ice Age about 10,000 years ago. It's interesting to find out that the ice particularly in the center of Greenland is about 10,000 feet thick and that there are still rivers of ice that are flowing towards the oceans where the ice then either melts or forms icebergs. This is a view of volcanic Turin in the central Andes in South America and I like this view because it's very exotic looking and if you didn't know you were looking at the earth you might think we were exploring another planet. The geologists are interested in pictures like this not only because of the many different types of volcanic landforms that they can pick out in the picture but also because there are a lot of dry lake beds and they can pick out ancient shorelines and some of the alluvial fans and they can also chart changing water levels in some of the lakes and there's a very small turquoise lake if you can see it up here in the upper right. This near vertical photograph of deforestation in Brazil was one of our earth ops targets that we were asked to study and shows two distinctly different agricultural land use patterns in terms of their maturity. The larger rectangular shapes down on the bottom of the view represent an older and more fully developed agriculture environment the smaller, less developed areas are more recent agricultural development. This scene is fairly typical of the landscape in southwestern Brazil by the way. Photographs such as these are excellent tools to illustrate the areas of change that are occurring in some more remote areas of our world. They provide the scientists with insight into the rate at which these tropical rainforest and the transition zones of the tropical rainforest are being altered and in some cases that's shown here in a very dramatic way. This is a photograph that shows the southern part of the Eleuthora Island in the northern Bahamas. Looks like a nice place to visit. As a matter of fact, if you look again at about 20 years you may see me on a sailboat down there someplace. The hook-shaped island encloses a relatively shallow platform as evidenced by the lighter blue color which is surrounded by the dark blue much deeper water. The feathery pattern in the center here is a platform of sandbars and sand channels created by the tidal currents that are moving in and out and off of the platform. The channels serve as a funnel to move large amounts of limestone off of the platform and down into the deeper water. This, of course, is a fantastic view of the Grand Canyon created by the Colorado River that starts in Rocky Mountain National Park in Colorado and then works its way down into Lake Powell right here created by the Glen Canyon Dam there and then cuts the Grand Canyon 227 miles long in total. Most of it that you can see in this view and averages about 10 miles wide and a mile deep. If you've ever visited the Grand Canyon you probably stood at the village on the rim right there and marveled at how magnificent the site was. Looked across to the North Rim that is in the Kaibab Plateau that is covered by snow here and it's just as equally a marvelous site from space. The Malaspina Glacier in Southern Alaska is a classic example of a Piedmont glacier lying along the foot of a mountain and then flowing into the sea. The principal source of ice for this glacier is provided by the Seward Ice Field that is up in the Northern area here and then the ice flows in to the glacier through these three channels. The glacier moves and surges and that moves the earlier formed moraines outward and expanding concentric circles and creates these patterns that you see here as it moves into the ocean. Going to the other end of the globe from north to south, we're down here near Antarctica. This is Herd Island which is down near Antarctica. And the special part of this picture is the wind patterns that you can see in the clouds here. As the wind flows past the island creates these vortices called Von Karman vortices. As the vortices develop, you can see how the cloud patterns develop and dissipate causing these opposing vortices in the wind patterns. So not only do we see the wind patterns but I also see the cloud formations develop there as well. We were very fortunate to have several crystal clear passes over Japan and this is the southern end of the island of Kyushu in Japan and up near the top of the frame you can see the volcano Sakurajima with a little bit of steam plume emanating from the top. You can also see quite a bit of ash collection near the summit and also what's striking on every pass over Japan is the population density. I think you can appreciate in this view several areas of population density, several large cities including just to the west of Sakurajima, a town called Kagoshima and it's interesting that the school children there have grown so accustomed to volcanic activity that they often wear hard hats to school. This is our last picture in our series of slides. This clearly is a mission that was dedicated to looking at the health of our planet and if there's anything that the entire population the planet's interested in it's the health of our home.


This is also a very general presentation, like introduction, what and how was researched in Central European, Central European Warnfields. Yeah, this is probably the end-list map you can find on Wikipedia. And this is Lusatian culture. But the interesting, of course, thing is that what these Warnfields they have in common, they covered the areas of completely different economic strategies, completely different communities. They have nothing in common, only the Warnfields. So this is very interesting. And when we look at these future areas, we can see that what they have in common is cremation, of course, but it's prevailing. We all know examples. And we also have today a presentation about those who didn't want to cremate that. And we also, from Poland, we have some examples of mixed burials on one cemetery, of course, the same chronology for some reasons. Some people were cremated, some were not. So cremation is what they have in common. The other thing, which is very remarkable for this period, is the impressive number of both graves and large cemeteries. And the next thing is common use of pottery, not the metals. We know a lot of cemeteries without metals. Large cemeteries made by communities who are very skillful metallurgists and they have a lot of bronze deposits or bronze objects on the settlements, but they don't put metals in the graves. So the urn is what they have in common. It's use of, rather of pottery. Of course, the pottery, it doesn't mean it must be urn. We have a lot of examples also of field graves without urns, but pottery is somehow involved in funeral activities, which is also a very interesting question, because in this part of Europe pottery manufacturing is very seasonal activity. You cannot do it in the winter. You cannot do it when it's cold and it's wet. So the issue of combining the funeral activities and use of pottery is also very, very interesting. About the cremation, what is the main, to me, a very interesting thing is that it was quite rapidly introduced. We know that in Hungarian play there are some places where the cremation is dominant type of funeral since the early Bronze Age, but this is like an exception. But then, starting from, let's say, 100,300 BC in central Europe, the cremation graves are completely dominant. But what is interesting is that we can see some changes in the meaning of body and its integration. And this didn't happen in the urn fields. What we see in the urn fields is the result of some changes that began before the urn fields. And probably the crucial period is the Tumuli cultures. However, you can call it in different parts of Europe, you can see the change from early Bronze Age tradition, which of course is the continuation of early Neolithic tradition in this site position. But then something happened in treating the body treatment in these Tumuli cultures, because, as you can see starting from this time, there was no way back. People never started to bury that as they did in the Neolithic in early Bronze Age. So this is the very interesting moment that people started to look at that completely different way. And what we see here is just the result of these changes. And when we look at the number of graves, this is large cementary in early Bronze Age. You have some, this is from Moravia, and this is from New Rotom from my place. So yeah, this is kind of large cementary. But when we compare the numbers with the urn fields, they are really very, very small. When we look at the urn field periods, first we have cementaries that contain a lot of graves. And in the Luzatian culture area, we have the estimations that there must be, that there could have been 7,000 to 8,000 cementaries used over centuries. Sometimes it's 1,000 years old. Just imagine, I come from the country that has 1,000 years, 1,000 history. So when you think about such long, when you think about cementaries used for so long time, it's just, for us modern periods, just incredible. But here you can make examples of some medium-sized cementaries. But when we look at really big, desiconic sites, every archaeologist student in Poland knows this site, like Bojewsko or Kiercz. In Kiercz there are like 6,000 graves. They are really very, very big and they were used for 1,000 years. So there are very few situations that the graves destroyed each other. So they were very well marked on the surface. People just knew where to dig, not to destroy all the graves. And some recent excavations, this is a famous site, very richly furnished graves from Tomasław in Poland. And there are like 200 cremation graves and chamber graves and princely graves or almost princely graves, very famous site. So the urn fields are important and stable elements of cultural landscape because if for hundreds of years people knew where the cementaries are, here in the very center of the circle you can see the green spot. This is just an example of micro-region from Wicina in Western Poland. And in the center there is fortified settlement. And we have like in the session, we have like three papers of Wicina, so I won't just now talk about it. But the pink spots are cementaries and the blue spots are open settlement. So these cementaries were very well recognizable elements of the landscape for a long, long time. And when we look at other analysis we can see of course the micro, this is called micro-icology, I'm sure you know the notion. So when we have the vertical spatial analysis and try to find the order within the urn, there are some examples, this is publication by Aleksandr Gramsci, but there are many examples of that. With one conclusion that first there were some ideas about usually we don't have the exact order, but usually the urn is closed with skull bones. And when you look at the reconstruction you can see that the people they started from the legs to the top, so what we find in urns that the head was at the top of the urn. And also this type of analysis can be done in non-invasive way on the computer tomography. This was applied mostly to plan the excavation strategy because as you know the bones are always very fragmented, very fragile and it's very easy to damage them during the excavation. So some measurements can be done on the computer and also you know what you will find in the urn because you can find, you can see some metal objects for example. And then we have some examples of special analysis horizontal and the grave level, also very interesting issue to me because this is an example from Niederkajna, a really huge urnfield from eastern Germany published mostly by Nebel Sieg and his colleagues. And he showed in this picture the sum of these some of these pots were secondary fired and also this is very interesting question why some grave goods were cremated together with the dead and some were not. This is why we don't have bone and antler objects in these graves because when we have these mixed ritual sites when we have information graves we have a lot of bone and antler objects but when it comes to cremation graves this is very difficult to find among these burned bones and sometimes we have also very good examples from the China site that we have in some graves we have some fragments of bronze objects and in other graves we have just bronze lamps but the weight is very much similar so probably these bronze pieces were burned together on the cremation fire. So this question is also very interesting but of course in central European archaeology what we have we have topology. This is something you cannot escape from when you were born in central Europe with this German archaeological tradition which of course is really good to have things order it but this is not like the final aim of any archaeological work but topology is also a very typical procedure in working on material. It can be focused completely on archaeological evidence but also combined with some anthropological as you can see you can topology of graves depending on the number of individuals buried in each context. Also technological analysis whatever you find you can just test it you can cut it and you can check what it is. So there are just examples of some objects clay from Moravia China site in Moravia but of course now we have spectrum of possible analysis with USWARE and GCMS as we have also very interesting results recently in UNDFILD pods. Some context studies this is also very interesting because as an archaeological student I was told that staff per grave was completely different from objects used in normal life but recent studies show first thing that most what we find in the graves was used before the position was in normal, has a normal life, normal biography and also there are very few categories of objects which were intended to be done to be made only to funeral purposes and here you can see some studies on the forest so you can see that there are some forests they might be intended to be used only in funeral contexts and some were mostly for settlement but these studies are also new in Central European archaeology at least about what I know. We have some special analysis on the level of whole cementary when you can see the colors are different chronology but we can see some graves with some rest and a plant rest, plant remains so also interesting question that it's somehow combined with the chronology so there was a moment that for some reason this plant was added to the graves and also some constructions you can see the red spots are chamber graves and of course social and ritual issues which are very rare in my opinion because archaeologists are convinced that they are very difficult to study which is true but this is not the excuse but we have also some indicators of possibly elites and I know the colleague from Balkans you speak about elite graves in Slovenia and Croatia so you have said of indicators or yesterday I was doing a session about motherhood and there was some marginalization some least of social indicators of higher status some were interesting, some were very intriguing like grave depth for example so I think everybody has its own private least of what can be indicator of social status and also very interesting in my opinion very interesting interpretation about the graves set of vessels we find in graves where somehow comparable can be comparable with what is called remains of some feast or libations when we look at these two pictures this is a grave inventory and this is kind of feast remains which we find in the settlement and there is a book unfortunately it's only in Polish and all this port from the one cemetery was measured and there was a kind of analysis of how the inventories have changed over time and it shows some differences in kind of feasting or making libations in the history and also very interesting like also published only in Polish so at least you will know it from me that the rapid introduction of cremation is very heavily connected with metallurgy so the fire is crucial issue here because in the same way it transforms metal objects it transforms human bodies and this is very interesting for me because we have very few answers why the cremation became so dominant and so rapidly in Europe and showing the examples from all the India is definitely not enough because in Harappa culture, in Bronze Age culture the cremation was introduced later in the field so it's not good example and also we have some reconstructions of rituals usually the framework is connected with rites of passage and this is just an example from Grams again when you put archaeological evidence into this theoretical frame of rites of passage this is of course these are the conclusions so we have, I must say that we have a lot of excavated sites a lot of published sites the quality of the publication is usually very very good but this is mostly descriptive there are mostly descriptions it's not important if it's data brought from GCMS again what you have you have data but you have to work on this data and I think the proportion between data and interpretation are still not enough what we have is not enough to know this very interesting period so this is it, thank you


What's everybody Jason here for Jasper's case breaks up on 2022 tops infinity baseball just sold out This is a one-box break pick a team number one where there's also a hit list credit guys I remember this is a high-risk high reward to have to break one pack per box eight cards per pack So there will be you know handful of teams that will be going hit list So all the teams that get hit list that go hit list will get $10 in credit each So for each team that you purchased You'll have $10 in credit back to you if you go hit list And I'll send that out to you at the end of the break. We did have to do a nine team R&B Those teams that are in this list and those customers will not be part of the hit list credit But you guys that still have an opportunity to hit some big hits for those teams for a fraction of the price there's a list of names and Here is The list of customers at bottom straight up. Thank you guys. We really appreciate it Good luck everybody So remember this is a three box case To change that really quick But here we go guys. Let's rip open the Case Again, we got three boxes guys Top middle or bottom. Let's see if I can roll one one two for the top three four for the middle five six for the bottom guys Four so one two three four the middle is where we're gonna go with And then I'll put these ones here as PYTs You guys know that it is pick your teams and then these will be for the next couple of Breaks there. All right cool. Yo guys. Good luck everybody again the next to pick your team guys is down to 13 If you guys obviously wanted to sell that one out, I would go grab your teams now I wouldn't doubt if Nick's already gonna put that into a random number block for the remaining 13 teams So we can sell it out Couple more teams that we had in the first one, but like I said, you never know depending on what we hit or what we don't hit Some teams can continue to hit some teams might go hit this here So we'll see you guys. All right, here we go guys. We're up the first one here. Here we go 15 of 15 Jean Segura Nice three color pass there for the Phillies going to Derek and we have a Test car Hernandez to 50 that's gonna go to the Blue Jays, which is part of the random number block 9 of 50 Spot 9 going to Chad Coleman on the board there Let me keep track of course, which teams have hit next one We have Larry Walker 8 of 40 That is for the Colorado Rockies Colorado Rockies That is Jeremy Port Jeremy you gotta hit take you out of that list. All right, here we go guys We have a JD Martinez 13 of 30 Little patch auto that is Boston Red Sox going to Gary Gordon Let's take Gary out of that list. We have a beautiful dual auto Two of 35 Justin Morneau and Joe Maurer both for the Minnesota Twins Going to Jarrett and the twins very nice very nice one right there Minnesota Twins with a hit Jarrett there you go We have Nolan Aronato one of 10 for the St. Louis Cardinals Going to John and the St. Louis Cardinals nice little frame right there. All right two more. It's guys We have a Josh Lowe Six of 50. That's a rookie autograph for Tampa Bay a little bit of a teaser to be honest Tampa Bay raised went to Michael. All right, the last one here guys is 10 of 25 Ozzie Smith 10 of 25 Nice signature.  So again Cardinals Tampa Bay Rays Cardinals again Twins Boston Red Sox Colorado Rockies and Philadelphia Phillies. There's your eight hits right there. All right one two three four five Seven I miss one on eight over here, of course part of the random number block So again, unfortunately guys for the rest of you guys you guys went Hey, let's buddy guys are gonna get back $10 and break credit and honestly this probably wasn't the best box out of the case I feel like there's definitely a lot more hiding in that Remaining two boxes. So you got the next definitive hasn't been around a number block yet So I would go grab those teams that potentially went hit list now and Maybe try to get some hits for them in the next one But like I said, I'll send you guys 10 credit $10 and break ready each for the customers that went hit list So here's the list of names right there So these guys right here are the customers that went the hit list I'll send you guys all $10 back. If you guys had multiple teams, then I'll send you you know in In a you know, if you bought two teams, I'll send you $20 instead of just two $10 credits, etc Etc. So I appreciate you guys picking number one in the books number two in the store down at 13 Still so available to purchase if you guys want to straight up Jasper's case breaks.com. Thank you


So, the next talk of this session is practical post-quantum signature schemes from isomorphism problems of trilinear forms. The talk will be given remotely by Gangtung and I will allow him to introduce his co-authors. So Gangtung, please go ahead. Okay, thank you for the introduction. So this is the joint work with Dong Huang Dong, Antoine Jokes, and Thomas Planter, Yoming Chao, and Wenyi Socilo. So I'm going to talk about practical post-quantum signature schemes from isomorphism problems of trilinear forms. Okay. So, first, let me give some preliminary for isomorphism programs and GMW plus IFS framework. So the classical graph isomorphism problem asks whether two graphs are the same up to relabeling the vertices. So look at these two graphs. The given two graphs G and H consist of a vertex set and edge set, where a vertex set N just delos a set from 1 to N. So we say that these two graphs G and H are isomorphic if and only if we have a random permutation belongs to SN, map to N to N such that we have sigma take this edge set E is equal to F. So this formula just means that for any edge consist of i, j belongs to E if and only if we have sigma i, sigma j belong to F. So there's some preliminary about tensors. So tensors are multi-way arrays. You can image if we have dimension two. The matrices are two-way arrays. So in this talk, we just focus on three-way arrays or we so-called three-tensors. Specifically, we define three-tensors is equal to a i, j, k for each one, a i, j, k just delos the entry belongs to field F and i, j, k for the index i, j, k belongs to N. So what's the tensors isomorphism problem? So like graph isomorphism, we also have an input for these two tensors A and B is the size of M cross N. The question is to find an invertible matrices L, R, T such that we have L act on this direction, the first direction and the invertible matrices R act on the second direction and the last one act on the third direction. So fellow from this three-direction action, so we get another tensor B. It is tensors isomorphism problem. So from this isomorphism problem, we can design a digital signature based on these problems and it is studied in multivariate cryptography and isogenic cryptography. And the construction is linear. We have two steps here. The first one, we just construct a identification scheme based on Goldratch, McCauley-Witterson, zero-knowledge protocol for graph isomorphism. And then we just use field Sharma transformation to turn this identification scheme to a digital signature. Okay, so let's look at step one, how to construct an identification scheme, a zero-knowledge interactive protocol for graph isomorphism. Just include two players, we call Prover and Verifier and they are given two graphs G and H. If G and H are isomorphic, the only Prover loads an isomorphism and the goals for the Prover, she will demonstrate that she loads the isomorphism without revealing it to Verifier and the goals for Verifier to guarantee it must satisfy these two properties, we call the companies and the sound is complicit. It is if G and H are isomorphic and the Prover loads the isomorphism, he always accepts. And the sound is that if G and H are load isomorphic or Prover does not load the isomorphism, he rejects with non-negligible probability. Okay, so let's look at what's the GMW zero-knowledge protocol for graph isomorphism. First, given two graphs G and H as our public key and let sigma be an isomorphism as secrecy, such that sigma sends G to H, so that we have sigma of G is equal to H. And then Alice generates a random permutation, pi, which sends G to K. So we have the below interactive process. Alice first sends K to Bob and Bob will run sample a B from zero one and return to Alice. When Alice receives B, if B is equal to zero, Alice just sends R is equal to pi to Bob, otherwise sends R is equal to pi times sigma inverse. And when Bob receives the response R, Bob will check if B is equal to zero, Bob checks whether R of G is equal to K, otherwise just checks R of H is equal to K. Okay, so that's the construction of GMW protocol as our identification scheme. Then we just apply field-sharmier transformation to get a digital signature. Field-sharmier proposes a method that's taken an identification scheme and turns it to a digital signature. The key idea is to use a hash function to simulate the interaction process. The identification scheme faced an isomorphism problem faced this method. Also, the field-sharmier transformation, the security of field-sharmier transformation just proved in the random oracle model. And very recently, it's also proved in the quantum or random oracle model. So, more generally, an isomorphism testing problem asks whether two combinatorial or edge-break objects are essentially the same. Besides graphs, isomorphism testing problem for groups, edge graphs, ledges, and linear codes have also been studied. But graph ISO is not good because graph ISO is low and very easy problem, both in theory and in practice. So, naturally, we'll have a question, can we rescue this framework, the GMW plus field-sharmier to other isomorphism problems? In 1996, part of it suggested to replace graph isomorphism with polynomial isomorphism. In particular, it suggested a digital signature scheme as we described. So, polynomial isomorphism is a family of problems. So, it just depends on the polynomial degrees, the number of polynomials, and so on. So, some from this family, such as isomorphism of quadratic or polynomials with one secret, is so-called IP1S turns out to be easy. And also, it gives rise to a series of walks in multivariate topography. Also, in isogenic-based topography, covenants, first proposed, the use of class group actions are inept curves in topography. They adapted the GMW identification protocol to this action, and Stone-Bullard suggested to apply the field-sharmier transformation to this identification problem protocol to get a signature scheme. However, the use of ordinary inept curves has issues, including the sub-explanation time quantum algorithm and slow performance. So, this leads to some serious walks next. So, the attention that tends to super-singular inept curves is so-called site or say site. This also leads to some bogus signatures again recently. Okay. So, let's look at the tensileism of them in the post-quantum cryptography. In post-quantum cryptography, we wish to devise cryptography protocols that are hopeful to resist attacks by quantum computers. This requires to utilize limitations of the quantum algorithm. And a later development of the short algorithm for integer factorization and the discrete log is the hidden sub-group program framework. So, one key reason for utilizing Knight's program in post-quantum cryptography lies in the connection with the dihedral hidden sub-group program. So, the best algorithm for dihedral hidden sub-group program is just a sub-explanation proposed by Cooperberg. So, similarly, a key reason for utilizing tensileism of the nice in the connection with the hidden sub-group program for general linear groups. So, for which there exists strong negative evidence for the current techniques to work. And also, there's some consequence of the strongness such insights we have about limits of quantum algorithms. Okay. So, here's some comparison of the best algorithm for graph iso and tensile iso. So, for the graph iso, we have a brute force algorithm running in time and factorial times polyn. In worst case, we have a causal polynomial time proposed by bye-bye. And in average case, it will be solved in linear time. And in practice, if we choose n, it's larger than 10 to the 6. It is very easy to solve. However, if we focus on the tensileism of them in brute force, we just run in time q to the n square times poly of n log q. In worst case, we have algorithm running in time of q to the 1 half times n square plus a constant. In average case, we have a q to the o n algorithm. Also, in practice, if we choose n, it's equal to 10 to the 11. So, the evidence shows us it's hard to solve. Okay. So, here's some criteria for constructing a secure protocol. So, first one is practical complexity and theoretical complexity and well-studied. So, the tensileism of them just satisfy all the above based on current evidence. So, G and Chow and Song Yang in TCC lighting may propose to use tensileism of them as the security basis for the GMW plus FS framework just based on advances on complexity and algorithms. In the complexity side, Fortune and Chow propose a complex class so-called tensileism of them. In the algorithm side, based on many works in multivariate cryptography and some of another works. Okay. So, laterally, we'll have a question. Can we make GMW plus FS plus tensileism of them practical? So, as I described above, Fortune and Chow define a new complexity class Ti complete consisting of problem that are polynomial time equivalent to tensileism of them. Next, we have GI complete just consists of problem that are polynomial time equivalent to graphism of them. Okay. So, let's introduce a new concept which called alternating trinomial form. So, first the way that GL and FQ be the general linear group consisting of n by n invertible matrices of FQ. And FAY is said to be trinomial if linear in all the three arguments, we say that a trinomial from FAY from FQ to then cross FQ to then cross FQ to then to FQ is alternating if whatever two agreements of FAY are equal and FAY will evaluate to zero. A natural group action of A belongs to GL and FQ on the alternating trinomial form. FAY just sends FAY UVW to FAY act on A and it just means A is transpose act on each agreement. So, let's give a definition of alternating trinomial equivalence like tensileism of them given two alternating trinomial from FAY and PASI whether there exists a invertible matrix A such that we have A just sends PASI to FAY. So, and computes one such A if it exists. And also we have a theorem it just says alternating trinomial form equivalence problem is in TI complete specifically that is ATFE and TI are poly time equivalence. So, here's some motivations from cryptography because of you if we want to implement this scheme we will generate the tensor we generated the alternating trinomial form but if we generate a tensor it will cost NQ but for the alternating trinomial form we just cost N truth 3 for example if we choose N is equal to line NQ is equal to 729 but N truth 3 is just 84. So, this is a big saving practice and also we have a practical algorithm for ATFE it's running in time Q to the two two-third times polynomial and no Q. So, also we just we also analyze some attack based on global basis. So, we have its environmental results on Naples and MACMA and it shows that if we choose N is smaller than 6 it will be very fast and N is equal to 6 and the Q is 5 it will run in about 700 second and N is equal to 7 it cannot achieve.  So, these these equations will be redundant for us but it seems helpful for global basis and this result shows if N is smaller than 8 it will be very fast and it will permit breaking N is equal to 10 but N is equal to 9 it also cannot achieve. So, it is reasonable to choose N is larger or equal to 9. Okay, so that's some parameter choice of our scheme and Namla delos the security parameter R delos the number of wrong and the two-third say just delos the number of alternating trinomial form generated in each wrong and we have some estimations about like R times C is larger than or equal to Lamla and we also have the formula of our public key size, private key size and signature size and with these estimations and based on the global basis attack but we can choose the reasonable R and C to balance our parameters like public key and private key and signature key size. Also, we have an implementation for our scheme and when we we have four concrete schemes one two three four and we choose the reasonable parameter Q and R C and we calculate the public key private key and signature size. Also, for the implementation, we have the running time of key generation, sign and verify. Okay, let's give a summary unlike graph ISO, ATFE seems to be a much harder problem both in theory and in practice and the hardest of alternating trinomial form equivalence can be explored to devise cryptographic protocols essentially in light of post quantum cryptography and we propose a practical signature scheme based on this problem and we also analyze attacks on the global basis and the final way choose the reasonable parameters well carefully to balance and implement this scheme. Thank you very much. Thank you. Are there any questions? If so, please go to the mic. Yes, so there's a question incoming. Hi, thank you for a great talk. So I was wondering what's the motivation to go to dimension three? What does this have that dimension two doesn't have and what about dimension four? Is that then even better? Which one dimension do you mean for alternating trinomial form? Yeah, so the motivation from the practice here motivation because if we use the tensile smoothing it will cost it will be expensive because if we store a center it will cost but if we just store a alternating trinomial form it will be untrue. So I guess I was maybe I'm a little bit confused but if we go all the way back to the beginning we're talking about matrices of dimension three or tensor products of dimension three where normally like I'm used to matrices of dimension two where you can only multiply them both on two sides and you're using matrices of dimension three and I was just curious about does that make sense? Yeah, yeah and I was wondering like what's what's the motivation to go to dimension three in this case of dimension three? What's the motivation go dimension three? Yeah, because if you if you just focus on these two dimensions it will be easy because if you just make this the second dimension for another side it will be to solve a linear polynomial. The problem will be to solve equations of linear equations. Ah okay thank you. Okay there's still time for another question. So I have a quick question so your four schemes parameter sets do they have they been set to match the AES sorry the NIST post quantum levels? Yeah it's this parameter just matched the security parameter for 128. Okay thank you. There's no other questions let's thank the speaker again.


Hey guys, it's Jen from iCreate Crafts. In today's video I will be showing you step-by-step how to package your car decals. If you haven't seen my last video I show you exactly how to create car decals. You can go back to that video and see how easy it is to create them I will also leave a link in the description below to that video I will leave all my supplies in the description below and as always if you have any questions Please leave them below and I will get back with you right away. Now. Let's get started All right guys, so I've been making a quite a few car decals and I've been selling them and they've been selling really well So I wanted to show you guys how to create this in case you're interested If you're interested in learning how to make car decals go back a video and I show you exactly how to make the car Decals, this is just going to be a video on how to package them. So I have this here how to apply decal I love this because it tells the people step-by-step how to do it I'm going to show you where I purchased this from so I purchased this particular SVG file from Etsy It's a printable how to apply a decal. I love it for $1.69 I was going to save myself some time so I didn't have to write it all out myself So there's a few things that you have to do with this I'm actually going to make this just a little bit smaller that we can see it on the page So there's two pieces to this There's this white background here the border and then you have the wording here as well So I want to select both pieces and I'm going to click on group And the reason I clicked on group is because I want this wording here to write out with the Cricut pen And here's where you can change the color if you want I'm just going to leave mine black and then so I'll show you that part really quick So I go to the basic cut up here and I'm going to change it to a pen and it's going to change it for me here So this all the white part here all the wording is going to be cut out with a pen But then we also have this part here.  So I have this one selected. I'm going to push duplicate three more times That we have four of these I'm going to try to cut out a four on one piece of card stock perfect So I could actually make it just a little bit bigger You just want to make it big enough that you can read this so depending on like what size your decal is If it's really large you can make these larger if it's smaller you can make a little bit smaller But you always want to make sure that you can read it and I actually did push Five on accident. So we'll just skip this one. So I'm just going to show you how to do this one So I'm just I'm going to push the continue button and then I'm going to show you which settings I use So when it comes to here, these are my base materials that I use all the time These are my favorite ones. So I'm going to be actually using this heavy card stock I like to use a really really thick stuff. So I'm going to push on that And then it's going to tell me to put in my fine point blade Which I always have in and then also load my purple pen I'm actually not going to be using purple. I'm just going to use black and then I'm just going to use miscellaneous Pieces of card stock paper. So you can change it whatever color you want. I'm just going to be using I think we'll try blue pink and maybe a green color and then I'm just going to use a black pen But it's going to tell you load your pen into your a clamp And then you always almost always have your blade and your b clamp So I'm going to go ahead and cut this out and I'll show you what it looks like And then I'll show you how to package these in the in the bags themselves Okay, so this is what they're going to look like when you're finished with it I'm just going to take a decal which I have here and then I also bought these bags on amazon I really like these. I'll show you really quick. So they are six by nine. I got 200 of them They're self-stealing bags, which I really really like So it's very simple to do it. So a mistake that you don't want to make that I've made is there's Obviously two ways you can put this in but you want your decal to be in the spot where you're not going to see this part here So you want to stick it in the front here. So easy Very easy. I gotta do is stick this guy in here In the front and then take one of our It's already sticking on here and then take one of our decal How to apply your decal that we just cut out and then you put it behind that one So I'm just going to do it right behind this and then if you have like a business card or anything you want to stick in here Whoops, and I put this the wrong way You can stick your business card in here as well I've done that but I just ran out of my business cards. I got to get some more So here it is how to apply the decal and then you have your decal on the other side And then I'll show you this is how the other one looks So I have my I create crafts business card in here That how to apply and then the other side has the detail on it So the last thing you want to do is just take this little Paper piece or this plastic piece off so it's self sealing And then just put it down and do it nice and neat And one thing that I've noticed with these bags is it keeps a lot of air in it So as you're putting it down kind of push out the air as you go Otherwise it's going to be really really puffy, but that was it It was as easy as this to make if you guys are interested in learning how to make the decals themselves I do have a tutorial on how to do that just go to a video back So this one is best I'm not saying that word ever And then I have these ones where it can go on your Gas can area I'm trying to find one if I have any more that are color So yeah, there's the mom life one again And then I have this help dad farted We can't get out kind of got to put that on my husband's car because self-explanatory Anyways, I hope you guys like this tutorial Give me a thumbs up if you did and hit that subscribe button If you're not subscribers you're ready and thank you to everybody who is subscribed and also helps me along with my videos I love your comments.

Hello and welcome to the session. In this session we are going to discuss the following question and the question says that solve the equation 4x square minus 14x is equal to minus 12. We know that the zero product property says if a into b is equal to zero then either a is equal to zero or b is equal to zero. It means at least one of the factors must be zero or both can also be zero. With this key idea we shall proceed to the solution. Now we are given the quadratic equation that is 4x square minus 14x is equal to minus 12. We have to find the solution of this quadratic. We see that this equation has non-zero terms on both sides of the equal sign. So we first move minus 12 to left hand side of the equation so that we can solve it. We get 4x square minus 14x plus 12 is equal to zero. Now 2 is the common factor in all the terms so we take out 2 common and we get 2 into 2x square minus 7x plus 6 the whole is equal to zero. Now we factorize this equation and we get 2 into 2x square. Now minus 7x can be written as minus 4x minus 3x plus 6 the whole is equal to zero. This implies that 2 into now taking 2x common from first two terms we get 2x into x minus 2 the whole and now taking minus 3 common from these two terms we get minus 3 into x minus 2 the whole and this complete whole is equal to zero and this further implies that 2 into 2x minus 3 the whole into x minus 2 the whole and this complete whole is equal to zero. From the key idea we use zero product property which says if a into b is equal to zero then either a is equal to zero or b is equal to zero. This implies that 2x minus 3 is equal to zero or x minus 2 is equal to zero. We should note that here we do not consider 2 is equal to zero as 2 cannot be equal to zero. Now solving these two equations for x we get x is equal to 3 by 2 or x is equal to 2. So x is equal to 3 by 2 and x is equal to 2 are the solutions of the given equation. This is the required answer. This completes our session. Hope you enjoyed this session.


Salutan al cio! I want to tell you something and last night I wanted to talk about two things First I wanted to show you something new and almost two weeks later I wanted to talk about Moriga First, my wife bought me this huge fan I really like it, it's a Chinese fan and as you can see it's huge, right? So I have to remember every radio in those days So the second and most important thing is that together I always go to the university and as I already said in previous videos but I'll just say it now I'm going to take a program that's called COVILO So the idea is not really... I don't know, it teaches you how to become a new entrepreneur but at the same time the COVILO, the COVA program helps you to become it So I'm going to take part in the ship of three people So it's me, it's Dmitri and it's Marina and we decided that first we want to create a new server where we help other entrepreneurs to become in this country, in Australia but later we think... No, we have to not think about it because of course after two years we started to do that and then we really thought about the best idea that we can do We worked together and then we thought, we have an idea and the idea is to create an application that helps people who are already good enough or even really good enough to speak English but they are not native speakers they learned it as a second language So the idea is that there are a lot of programs that help you to learn the language from a native speaker and after that we often say that you have to read that and that and watch movies or listen to the radio and more and more and more and only then you start more and more native speakers So we decided that we want to create an application and this application is for those people who already speak the language very well but want to improve their ability in that language and that language is English I don't know if I said that because the application has two goals the first is to help people and the second is actually to help them to succeed in passing other exams So for example in Australia there are two serious and big exams and one is called and the other is called and the first is for people who want to migrate to Australia and they want to make Australians I don't know why and the second, the eighth is for people who are for example curators or refugees in other countries where the English is not the main language and they transferred to Australia and they want to be a curators or a refugee here but first they have to prove that they speak English well enough So my second work not my third my third work is this channel but my second work is to teach English to those people and I started doing that two months ago and I already have more 15 students so some are students some are students and so on so I help them and I think maybe we can create an application that really can help them because for example when I was with my wife when we first met each other she speaks English very well but it's a problem there are a lot of cultures references that I do in often conversations and she doesn't know about them because she has never participated in that culture media so for example often I tell things about the military so I am your father and there are a lot of things but she has never waited for that movie so we want our application to help them about that so she gives to them a lot of often used words two it helps them for the the best of certain phrases so for example in China people say that you are on the balcony not on the balcony in English we often say that I am on the balcony sorry that's a bad word because in Esperanto it's now I'll say it in English it's a word and that's a chamber which is almost on the balcony it has big windows and of course it forces the sound to go to the chief part of the house and in China they don't have a word only for that they have a word for the balcony and that's and also that can mean on the chamber so the problem is that they say that you are on the balcony on the chamber but in English we say that we are on the chamber so they often do of course that age when they speak about that chamber that part of the chamber so we want that we program without basically Chinese speakers I suppose and help them relate to that so the right choice of certain phrases phrases words words and so on so for example when I study English as a curator as a photographer they often know the words and the right words so for example in English and so on but they don't know how to use it with the right words because they simply don't use it they study the words and maybe use them in some contexts but never actually study how to use it in all contexts so of course our application of that person and teach him how to use that phrase just because there are many other phrases that you can use in English and they are grammatically right but they aren't used there and that's my goal is to help people speak English more naturally more more naturally I guess and I need your help because I created an application and the application is a principle for all speakers of English also it's good if I can hear from other world parties so it's an application for writing and I want you to just go there and answer the questions in English because all these people who study English and are not of course able to speak English so just go there and answer my questions because I need a lot of answers to create the basic concept of the application with my script and that is all people and if you liked this video like it share it and I will see you in the next video and if you are not there I will find you and someone will find you for me


The Yorksen area of Langley is growing at a really rapid pace. We have lots of schools around that are very crowded. We've already opened Lynn Fripps. We've got Richard Bulpip Elementary coming on stream and today we broke ground on the Yorksen area middle school for students in grades 6 to 8. That will open in the fall of 2014 and we're very excited to see this growth in our community and now to be able to respond to it with new schools. Having experienced attending a brand new school at the beginning of September, I am overjoyed to be going to the middle school in a few years. Walking through the doors on your first day at a new school is exciting, much like embarking on a new adventure. From a student's point of view, not knowing the exact plans of building, it's completely incredible to watch an area of cleared land transform into a large school in a matter of a few months. I cannot wait to feel that awe and sense of excitement again. We're very excited, aren't we, about this new middle school that's going to come into this community. Our high school is overloaded. We have double the amount of students that it should have in terms of capacity. So opening this school will take the pressure off the high school and these guys are very excited about leaving their elementary school and having the opportunity for a middle school learning opportunity.


So my beautiful people I am back with another out on ring video and a short but sweet one for you guys today and how you can get these amazing beautiful locking Beastman's Curve Swords. How's it going guys, my name is DPJ and if you do enjoy the video leave me a like if you like what you see and if you want to see more be sure to subscribe. Ok so a weapon I haven't seen many people cover has actually sent a video on my discord and to me they were new, I'm not saying they're the worst weapon in the game I definitely don't think they are, like every Curve Sword though if you dual wield them they have that beautiful nice 4 hit attack which can be pretty powerful, quite a few Ashes of War on these guys as well, make them even better, they scale with strength and dexterity, attributes required are 13 in strength and 11 dexterity and well they're quite easy to get. Now the problem is it's getting to the area which is an end game area before you can actually grab these things, so to get these you actually have to go to the dragon temple so you first need to take out the fire giant, come to this massive dome, I believe you talked to Malina it's been that long since I got there and you're spawning literally guys at the dragon temple, I think you're spawning around here maybe, here I'm not sure but this will be the first grace point you've come to and we're going there now guys and I'll show you exactly how you farm these, now Silver Scallop if you have it will obviously give you an increased chance in getting these to drop but yeah I just think it's a nice decent weapon and a lot of people out there love these Curve Swords, my net leveled up I ain't going to waste my upgrades on them, my materials on them because I don't think that's necessary for me but hey the grace point we're at is this one right here guys you literally activate this, come out of this room, turn right you'll see a ton of these adds right here and then just take it, simple as that now I had to drop of these in literally 10 minutes I mean if you've been through this area and a lot of endgame players have obliterated this area so yeah you've probably got these weapons already but hey you can see these actual weird looking werewolves dog things I don't know what they are and these are the guys that actually dropped them so there's quite a few here guys you can farm as you can see just killing more quite easy if you're high enough level going back to the grace point guys we set it we need to repeat and what a good guys it really is that simple for you guys there we have it that's how you get the Beastman's Curve Sword, a weapon I would say it's easily missed to an extent I mean it ain't the most common drop I mean the silver tier mask and the silver scaled medallion or talisman will help you get these things but hey if a strength or dexterity bird is something you're interested in if you like those Curve Swords these are pretty cool guys and like I said they're definitely one for the collection but there we have it people guys if you enjoyed the video leaving a like really helps out if you like what you see once you more add a ring be sure to subscribe and hopefully my beautiful people I will see you on that next one


When I talk about money, I often bring in the principle of enough-ness. If we focus on just earning what is enough, right, we'll have a lot less stress in our life and in our work, and we'll be able to do work that is a lot more fulfilling. We'll be able to bring more energy into into that pursuit, instead of always pursuing more. Now the question, of course, naturally follows, well, how do we know what is enough? How can we know? How do we gauge that, get that calibration of what is enough and therefore know what to aim for? I'm gonna have a lot more thoughts in the notes of this video, but I'll just highlight a couple things in the video right here. One is the media that we're consuming. The messages that we are consuming in our emails, in our social media, as we go around town and look at billboards, are we getting the messages from marketers that we always need to be earning more, always need to be buying more? If that's the case, we're always gonna feel that we don't have enough. The second one is are the friends, the family, the colleagues that we hang around. If we have people around us that are always aiming for a higher income, then we feel like, well, gosh, maybe we should aim for a higher income and we'll always feel like we're chasing never enough because then we're comparing ourselves with them. And finally, it is about what kind of work are we doing? Are we doing work that really fulfills us? If we do work that fulfills our hearts, that makes us feel like we're really serving and helping others, then that sense of fulfillment goes a long way in our life and it actually satisfies us in such a deep and profound way that we don't feel like we need to buy more things, go on vacations to feel fulfilled and happy. Of course, we go on vacations to rest, renew ourselves regularly, but we don't feel like we have to fill our lives with more and more spending because we feel so fulfilled already from our daily work. And so this is why I preach the message of building an authentic business because more than any other career, I look at people in jobs and very few people who are in jobs feel fulfilled because they're doing stuff that other people tell them they have to do. And bosses and companies are usually not very sensitive to giving you work that is really fulfilling for you. Or people build mainstream traditional businesses that are just all about the money and they realize, God, I don't really feel fulfilled doing this. That's why I'm such a believer in the message of building an authentic business and I really believe that everybody should think about the possibility for themselves of building an authentic business. And if we do and if we're able to build that, we feel so fulfilled, which then brings down our requirements for spending more money trying to fill the hole inside our hearts, which really a lot of that can be filled with our daily work that feels so connected in service to others and in the expression of our souls.
