The Secret Life of Chaos
Almost 99% of the human body is a mixture of air, water, coal and chalk, with traces of iron, zinc, phosphorous and sulfur. Somehow trillions of these
ordinary atoms become organized into thinking, breathing, living human beings.
How the wonders of creation are assembled from such simple building blocks is surely the most intriguing question we can ask. Woven into the simplest and basic laws of nature is the power to be unpredictable. Inanimate matter, with no purpose or design, can spontaneously create exquisite beauty. The same laws that make the universe chaotic and unpredictable can turn simple dust into human beings. There is a strange and an unexpected relationship between order and chaos.

Biologically Inspired Vision Systems
Scientists at The Rowland Institute at Harvard are working on enabling computers to see its surroundings, just as humans can do, using biologically-in
spired algorithms that enable computers to understand what they see.
Recognizing objects in the natural environment is something humans do naturally, without even realizing they’re doing it. However, what computers see is very different from what we see. To a computer, each image is just a collection of numbers.
How does biological vision work? When we look at a particular scene, the light from the scene enters our eye and is measured by the retina – the layer of light-detecting cells at the back of the eye. From there, information is transmitted along the optic nerve, through the mid-brain, to the cerebral cortex.

Future of Transportation
This documentary discusses the future of automotive travel, air travel, anti-gravity, virtual reality and teleportation.
It begins with the aut
omobile. Science fiction has always painted amazing pictures of future travel. John Clute, the author of The Encyclopedia of Science Fiction, points out that science fiction “has always loved the idea of travel”. “Flying cars,” he points out.
“Vaccum tubes down which rocket-shaped projectiles would be dashing. We’d find tunnels under the sea. We would find gigantic airplanes with thousands of propellers.”
But while the imaginers of science fiction were creating a fantastic future, most real engineers were pinning our hopes on the automobile.
Science fiction has always known the answer. “Take to the skies”. In other words, put wings on a car and let it take to the skies.

Sixth Sense
Pranav Mistry is the inventor of SixthSense, a device one wears “that enables new interactions between the real world and the world of data.”
I
n this video, Mistry shares the impetuses that drove him to invent a variety of devices that allow, or will allow, people to interact directly with their computers without the need of keyboard and mouse.
He started out with a “gesture interface device”, simply by cannibalizing two mice and using the rollers within! Rather than using a keyboard and mouse to interact with a computer, Mistry wanted to use his computer in the same way that he interacts in the physical world. This device acted as a motion sensing device, so that whatever movement he did in the physical world is replicated in the digital world.
From this starting point, Mistry went on to improve sticky notes. He wished to connect the normal face of sticky notes to the digital world.

History of Microsoft
Bill Gates started out as a shy, computer-obsessed teenager, and ended up the richest man in the world.
William Henry Gates III has built an em
pire thinking way outside the box. Now, after leading the digital revolution and facing several government anti-trust battles, Bill Gates is a different man than he was just a few years ago. He is a devoted father, and an avid golfer, who just happens to have a portfolio worth 50 billion dollars.
The values that shaped Bill Gates as one of the business titans of the 20th century go back to his roots in the great northwest. Bill’s great grandfather, J. W. Maxwell, founded the 1st National Bank in Seattle. The Maxwell’s enjoyed their privileges and social position, but were never ostentatious about their wealth.

Bio Fuel Jet
According to Doug Rodante, who has designed an aircraft powered entirely by renewable biofuel, there is a significant C02 output used in aircraft avia
tion. Rodante and his chief pilot, Carol Sugars, made a flight in 2007 to test the fuel.
Biofuel gels at a certain temperature, and as a plane increases in altitude, its temperature decreases. Fuel viscosity is very critical to the performance of an engine. The viscosity has to meet a certain range for the fuel to be usable. The biofuel engine was first tested on the ground before being used in the air.

Flexible Solar Cells
Solar panels are flat, rigid and heavy. Materials engineer John Rogers has figured out a way to make them lightweight, flexible and transparent. Roger
s and his team at the University of Illinois invented a way to use ultra-thin slices of silicon, using a printing-like process that transfers them onto lightweight plastic or even fabric.
Tests showed that these ultra-thin cells are just as efficient, while using much less material. Rogers believes that this flexibility and transparency will allow solar to be used in a wider variety of applications, and because of this flexibility and transparency, and thus lack of fragility, they will also become much more affordable.

Diffusion Tensor Imaging
Brain surgery is a tricky operation. The brain contains thousands of nerve tracks, each in charge of a different function – like speech, motion, memor
y, vision etc. One false move could cause major damage. “A few millimeters difference…makes a big difference, for the patients, for quality of life after surgery.”
Until recently, doctors had to guess where these nerve tracks were. Now, researchers at St. Jude are using DTI – diffusion tension imaging – to plan surgery. The DTI allows doctors to see every nerve track in relation to the tumor. DTI works by measuring the movement of water molecules in the brain.

Michio Kaku on Bose Einstein Condensate
Everybody knows the laser – the laser is everywhere. Laser is based on light. Light that vibrates in unison, called coherence. Wouldn’t it be better,
suggests Dr. Michio Kaku, if we could do that with atoms. Have an atomic laser – atoms vibrating in unison.
Albert Einstein and Satyendra Nath Bose showed in 1924, mathematically, that if you cool down a substance so it is really, really cold, all the atoms vibrate in unison, and you have a super atom. With this, you could test all the bizarre features of the quantum theory for large objects, because everything is vibrating in unison. However, Einstein didn’t believe it was possible to cool down the atoms to absolute zero (because of the third law of thermodynamics.) However, science has progressed so that atoms can be cooled to near absolute zero, and so experiments with the Bose Einstein Condensate are now starting to bear fruit.

Water on Mars
For the last ten years, NASA has been looking for evidence of water on Mars. Now, it has been confirmed that water, in the form of ice, does exist the
re.
The ice is underground, which is where NASA was expecting to find it. Phoenix is a lander, not a rover, and thus does not move. It has a long robot arm which can dig into the ground. This arm has dug deep down into the soil for a sample, which has then been put into a tiny laboratory inside the Phoenix, and after tests it has been confirmed to be water. Within this water is a chemical that could possibly support life.
