3D movies and TV are is increasing in popularity, but is any of it truly 3D? How true is the 3D in movie theaters? How do glassess-less 3D TVs work? Try catching a ball with one eye closed. If you find it easy, try having the ball thrown a couple of feet in front of you, or from further away. It becomes increasingly difficult when the throw is off. instagram.com/thephysicsgirl facebook.com/thephysicsgirl twitter.com/thephysicsgirl physicsgirl.org Help us translate our videos! http://www.youtube.com/timedtext_cs_panel?c=UC7DdEm33SyaTDtWYGO2CwdA&tab=2 Thank you to Greg Kestin for helping to research and write this script!

It is early in the morning as Vidal gets himself ready. But before Vidal can brace himself for his dangerous way to school he must take care of his family`s sustenance – like every morning he checks the fishing nets. After work it`s time for a Uro bread and he drinks a Mate tea. Both things, like almost everything else here are made form the totora reeds. The Uros are a people that are very rooting in their tradition. They have even managed to preserve the Pukina, their mother language dating back to the colonial time. After two hours of paddling, Vidal reaches the center of the village. He floats past houses, where a family is building their new island since the old one has began to rot. It is the normal rhythm here. Every three years a new ground under the feet and a new roof above the head needs to be made. The construction begins by cutting the roots of the totora reeds in 30 cm long blocks. Five hundred of these are then tied together with ropes and soaked in the water for three months until they melt into one large block. On top of this block, the family piles totora reeds up to two meters high, until a part of the block sinks in the water and starts to rot. The gases released from this biomass under water produce a buoyant force that causes the new island to swim. After three hours of paddling, Vidal has finally reached the Uro elementary school where he learns to read and write. Here besides his native language, he also learns Spanish. It is not the language of his parents, but at the same time it is his chance of a future outside of his village.

What would have happened if the Schlieffen Plan had succeeded? Find out on AlternateHistoryHub: http://bit.ly/1VJ9T0U The Schlieffen Plan was the blueprint for Germany s army to avoid a two-front war with Russia and France. It was supposed to be the solution for a quick victory against arch enemy France by invading Belgium and the Netherlands to circumvent French defenses. Helmut von Moltke adapted the original plan by Alfred von Schlieffen and ultimately failed when the Germans were beaten at the Battle of the Marne. Indy explains the numerous reasons why the Schlieffen Plan was doomed to fail. " » HOW CAN I SUPPORT YOUR CHANNEL?

Twice a year the forbidding journey to the boarding school is necessary. Father Latak, looks to the sky and attempts to predict how the weather will develop. Only when he is sure that no storm is brewing, he starts to prepare the children for the trip over the river. It is a route that is so notorious, that it even has a name: Chadar - the path over the cloak of ice. One last time, his ten year old son Motup, plays in front of their hut. Motup is one of the few kids who regularly leave the village in order to attend one of the the better schools in town. Then the family gets ready for the long trip. The mother has sewn thick wool socks for the father and the children, and Tebean prayers and mantras are recited for protection along the way. Then the trip begins, where the children muss trust completely the experience and skill of their father. The first steps, only a few kilometres until the frozen river, seem easy for the family. But father Latak recognizes immediately that the spring has come early this year and the sun has already began to compromise the ice. This is not a good sign, since the thinner the ice the more dangerous the trip becomes. Latak goes before the children and tests with a stick before each step on the ice. Often the ice cracks a bit, but the ice remains whole. Latak knows that no one should travel the Chadar without a good reason. But the education of the children is a good enough reason to take on the risks involved. He knows that if he goes first and the ice carries his weight, that it will also carry the weight of the children. If it does not, it will be he that will fall in the icy water and not his two children. At the same time, Latak, Motup and the other members of the crew must keep a close eye on the mountains. The massive mountain ranges on both sides of them seem to be a scene form a picture book, peaceful and lordly. But there is danger lurking. At any given time, an avalanche can break out. Many times before people have been caught by avalanches here. In the mean time the sun has already thawed the middle of the river. But since there are steep rocks right and left, Latak must now search for a new path for them to continue on. He leaves Motup behind him and luckily finds a way. It is a 20 cm wide path on the rocks at the edge of the river, and up to ten meters high. They need almost an hour, skipping from rock to rock until they finally reach an area where the river is again covered with ice. Now they must find a place to set up camp as soon as possible before it becomes dark and the temperatures sink to as low as -30 degrees Celsius. Latak knows a cave where they will be protected and finally be able to get some rest. They must gather their strength because the most dangerous part of the Chadar still lies before them. The ice is almost completely melted. Only a 50 cm wide strip borders right and left the ice-cold water, making the river absolutely impassible. Rocky overhangs above the ice block the way. Father and son must now crawl its way to school. Father Latak tests his way over the ice on his belly. After any progress made, he pulls his son by their hands to him. There are countless dangerous situations that make this way to school so unpredictable. But after four days it is over, they have reached their goal; the city of Leh and the school.

Those who attend school in the mountain village of Kumpur, walk across the mountains of the highest situated country on earth. Nearly half of Nepals lies more than 4 000 Meters above sea level. Today it s normal that the kids go to school in the valley, but just 50 years ago the village was completely self sufficient. Only if there was a lack of salt would someone twice a year hard off to refill the stock. Today the children go to the city almost on a daily basis and are immediately forced to cross the dangerous river. A village in distress is left behind. The village community Kumpur is spread across 18 farms on the Dhap Mountain. Their families live in a very remote area. These families have lived on their land now for thousands of years herding their life-sustaining cattle without electricity, running water or contact to the outside world. Although they constantly ask themselves if the promise of an education justifies the danger of the path involved, they send their children day after day to school.

Siberia. Endless vastness – arctic temperatures. Even farther East than Japan and 5 000 kilometres north of Vladivostok lies Yakutia, the coldest republic of Russia. Yakutsk is the capital of the Yakutia republic and is located about 5100 kilometres east of Moscow. In the midst of it: Oimjakon. With its 500 residents the coldest inhabited place on earth. This village lies in a mountain valley on the upper reaches of the banks of the Indgirka River. One of the major reasons for the freezing temperatures is the great distance from the Atlantic Ocean and the humidity that the Ocean provides to a major part of the Northern Hemisphere. Masses of mountains shield Siberia against the warm air from the west and south, while in the opposite direction, the door to the Artic stands wide open. Thus in the winter, cold masses of air expand into the Siberian landscape completely unrestricted. The average temperature in winter: Minus 40° Celsius. The children of the Siberian Oimjakon have the world`s coldest way to school. The extreme living conditions are completely normal for the residents of Oymyakon. This is also true for the Tariks family and their son Aljosha. He is 8 years old. The children of his age group are only excused from attending school on account of the cold at temperatures below minus 54° degrees. Even before his departure for school Aljosha feels the grim cold. Lacking running water the house also has no bathroom. So Aljosha alredy has to go outside – to the unheated outside earth closet in the garden. Sascha’s mother cooks tea. In order to do so, she must go to outside to the front of the house, which is made of wood- as all houses in Oymyakon. Due to the great temperature differences here, concrete walls would soon crack and be destroyed. In the short summers, it can get quite warm in Oymyakon. In front of the wooden house the ice blocks are stored. The next-door farmer had cut out of the frozen river for them. There is no running water in the Pole of Cold, with temperatures dropping to -65 degrees Celsius; no pipe work has a chance. Aljoshas mother puts the ice in the pot and cooks some tea for her son. Like every day, Aljosha must get ready to go to school. Like the majority of the other students, Sascha wears for the most part his traditional dress. The clothing prescribes to the onion-peel principle in order to protect the students from the Artic temperatures. His mother Irina has heated up the living room to 20° degrees. So when Aljosha opens the front door it is 70° degrees colder – every day life in Oimjakon. As soon as the children open the dormitory’s double doors, the icy cold brutally grabs hold of them. Within less than one second their nostrils become frozen. Unlike the students in other parts of the world, the children from Oymyakon are seldom playful but instead very concentrated on their way to school. With quick steps, they travel in groups, attempting to put the 2 kilometer route behind them as quickly as possible. There are no signs of snow ball fights. The don’t spend a second of time watching the cows, which are kept up to nine months of the year in their stalls, and are now coincidentally being lead out of the barn for a drink. Even though the cows are wearing some sort of special “bras” which protect their udders from freezing. Once in school building, Aljosha and the other students remove many of their layers of clothing, and get going with the school lessons. For the majority of them, a welcome diversion from the coldest inhabited town on the earth.

I built this tiled roof hut in the bush using only primitive tools and materials. The tools I used have been made in my previous videos. It should be pointed out that I do not live in the wild and that this is just a hobby. It should be obvious to most that this is not a survival shelter but an experiment in primitive building technology. To cut and carve wood I used the celt stone axe and stone chisel made in this video. To carry water and make fire I used pots and fire sticks made in this video. Finally, to store fire wood and dry, unfired tiles, I used the wood shed built in this video. The wooden frame was built with a 2X2m floor plan and a 2m tall ridge line with 1m tall side walls. 6 posts were put into the ground 0.25 m deep. The 3 horizontal roof beams were attached to these using mortise and tenon joints carved with a stone chisel. The rest of the frame was lashed together with lawyer cane strips. The frame swayed a little when pushed so later triangular bracing was added to stop this. Also when the mud wall was built, it enveloped the posts and stopped them moving altogether. A small kiln was built of mud from the ground and a perforated floor of clay from the creek bank. It was only 25 cm internal diameter and 50 cm tall. Clay was dug, broken tiles (from previous batches) were crushed and added to it as grog and it was mixed thoroughly.This clay was pressed into rectangular moulds made from strips of lawyer cane to form tiles. Wood ash prevented the clay sticking to the stone. 20 tiles were fired at a time. 450 flat tiles and 15 curved ridge tiles were made with only a few breakages. 26 firings were done in all and the average firing took about 4 hours. The fired tiles were then hooked over the horizontal roof battens. An underfloor heating system was built into one side of the hut to act as a sitting/sleeping platform in cold weather. This was inspired by the Korean Ondol or “hot stone”. A trench was dug and covered with flat stones with a firebox at one end and a chimney at the other for draft. The flames travelled beneath the floor heating it. After firing it for a while the stones stay warm all night with heat conducted directly to the sleeping occupant and radiating into the room. The wall was made of clayey mud and stone. A stone footing was laid down and over this a wall of mud was built. To save on mud, stones were included into later wall courses. The mud was dug from a pit in front of the hut and left a large hole with a volume of about 2.5 cubic metres. The finished hut has a swinging door made of sticks. The inside is dark so I made a torch from tree resin. A broken tile with resin on it acts as a small lamp producing a lot of light and little smoke. The end product was a solid little hut, that should be fire and rot resistant. The whole project took 102 days but would have taken 66 days were it not for unseasonal rain.

What if we could see the universe as a whole? We ve been trying to see and describe the large scale shape and structure of the universe since the dawn of science. Now, with powerful telescopes and supercomputers we have what earlier generations might have thought was a truly "God s Eye" view of creation. Those same technologies suggest that our view is still highly limited.

For centuries now, the Dorn Savanna has been the lifeline for the Massai people. Until today, they refuse to get involved in the constant upheavals in Kenya and instead continue to cultivate their traditions. The Massai have lived in the border region between Tanzania and Kenya for hundreds of years; almost completely removed from all civilization. In some ways their remoteness has spared them from many ordeals. But on the other hand, this autarkical life can be problematic, especially when it comes to the education of their children. This is also the case in the Massai village Kasiole. 12 families live in the village. Each hut has two rooms and in each one there lives a family with at least 5 children. Here, there is no space for a school, and needless to say, there are also no teachers. Therefore the children from Kasiole must walk for hours each morning to get to school. Most of the children stay at home and tend the cattle. Many parents are afraid to send their children off on the 10 kilometers long way to school right trough the savanna. 4am. Before going off to school the nightwatch is the task at hand. 8 year old Moseka guards the family s cows and goats. Sometime wild animals sneak into the village at night – a threat to everyone. When dawn sets in at around 6, the Maasai village Kasiole comes to life. Moseka s nightwatch ends – and his way to school begins. Students like Moseka from all across the region are setting off this morning on their way to the only school far and wide. Moseka`´s mother worries. In the last few days elefants often visited the area – the Massai consider them to be one of the most dangerous species in wilderness. His mother warns him once again about the possible dangers along the way. The first kilometres take the children through the burning hot savanna, and this without any water. The family does not have the means to afford a drinking bottle. Their route takes them pass amazing landscapes, and also different Massai villages, some of them already deserted and some just newly built. Through their way of life, it makes no sense for the Massai to build large houses. They will only live 2 to 3 years in them and are built traditionally with walls made from cow manure and straw covered roofs. Only a few children join them from the other villiages, although in Kenya schooling is mandatory, but not enforced by anyone. The way to school lead Moseka and his friend through the leopards valley – infamous for roaming predators. The Kenyan savanna is a huge open air zoo with an incredible diversity of species. Seen from the perspective of parents who send their children to school every day, it is an unfenced zoo, though. An open space whre the natural law of eat or be eaten is part of every day life. It takes a bit of courage to go to school here. The students destination: The Ntuka Primary School. The only school within a radius of about 20 kilometers. Often they are too late, but the teacher understands, he is aware of the long school route.

The equations of physics suggest time should be able to go backwards as well as forwards. Experience suggests, though, that it cannot. Why? And is time travel really possible? Click here to subscribe to The Economist on YouTube: http://econ.trib.al/rWl91R7 Why does time pass? It is a question so profound that few people would even think to ask it. Yet its effects are all around. Human beings live in a perpetual present, inexorably sealed off from the past, but moving relentlessly into the future. For most people, time seems to be something that is just out there. A thing ticking away in the background - fixed, immutable. Time seems to go in one direction and in one direction only. But physicists see it much differently. One of the great minds who changed the way science thinks about time was Albert Einstein. In 1905 he published his special theory of relativity. In it he demonstrated that time passes differently in different places depending on how those places are moving with respect to one another. Einstein showed that the faster one travels the slower time goes for the traveler. At the speeds at which humans move this is imperceptible. But for someone traveling on a spaceship at speeds close to that of light, time would slow down compared with its passage for people on earth. There was another important aspect of Einstein s theory which he didn t even realize when he published it. That time was woven into the very fabric of space itself. Einstein used this insight to help develop his general theory of relativity which incorporated gravity. He published it in 1915. With the general theory of relativity he demonstrated that massive objects warped the fabric of space-time. It is this curvature that causes time to slow down near them. Time slows down in proportion to the gravitational pull of a nearby object so the effect would be strong near a black hole but milder near the earth. But even here it can be detected. Einstein s theories had to be taken into account when the GPS system was set up otherwise it would have been inaccurate. One scientist who puzzled over the directionality of time was Arthur Eddington, a 20th century astronomer who defined the concept of the arrow of time, based on observations made by the 19th century physicist Ludwig Boltzmann. The arrow of time is based on the second law of thermodynamics which says the disorder known as entropy increases with time. For example, a building left untouched will slowly decay into its surroundings. It will disintegrate into a more chaotic state but it is highly unlikely that the building will become more orderly over time - this is because there are many more ways for a system to be disorderly than orderly. There can be many ways for something to break for instance but only one way for it to be put back together again. A system will be less disordered in the past and more disordered in the future. This is the arrow of time. So how can the arrow of time be reconciled with Einstein s equations? If time can go forwards and backwards according to relativity does that mean it s possible to go backwards in time? The theory of relativity does allow time travel to the future. Einstein s theories do allow for the formation of wormholes in space. These are shortcuts that link otherwise distant places in the space-time continuum. Although wormholes are theoretically possible they re a highly implausible proposition. That s because the equations suggest enormous masses and energies would be required to create and manipulate one. What remains then is a mystery. Theory fails to forbid traveling backwards in time but practice suggests it might just as well be forbidden. For now it would appear the arrow of time cannot be reversed. No one knows why time passes but it seems that no matter how people look at it, it goes in one direction in one direction only.
