In the years since Miller's initial experiments, scientists have come to believe that the atmosphere of primitive Earth wasn't made up of the same gasses that he used in his initial study. But volcanic eruptions were likely very common during the early history of the planet and these volcanoes could have emitted clouds rich in hydrogen, methane and H2S, which would create conditions similar to Miller's experiments in limited geographic areas. The spark could have been supplied by lightning, which is commonly associated with volcanic clouds.'

Sixty Symbols regular Professor Phil Moriarty discusses transparent glass and the so-called energy gap.

I really love this where art, science and design is coming together, simply beautifull!!

Hans Rosling's famous lectures combine enormous quantities of public data with a sport's commentator's style to reveal the story of the world's past, present and future development. Now he explores stats in a way he has never done before - using augmented reality animation. In this spectacular section of 'The Joy of Stats' he tells the story of the world in 200 countries over 200 years using 120,000 numbers - in just four minutes. Plotting life expectancy against income for every country since 1810, Hans shows how the world we live in is radically different from the world most of us imagine.

Mike Wesch, a 2009 National Geographic Emerging Explorer, talks about the future of communication and education, and describes the inspiration behind—and breakthrough success of—his wildly popular video Web 2.0 The Machine is Us/ing Us.

A great documentary from the BBC about the brain.

In this clip, Marcus Du Sautoy (Professor of Mathematics at the University of Oxford and current Simonyi Professor for the Public Understanding of Science) participates in an experiment conducted by John-Dylan Haynes (Professor at the Bernstein Center for Computational Neuroscience Berlin) that attempts to find the neurological basis for decision making.

Nice documentary with Richard Hammond. What if we could see beyond the narrow boundaries of our eyes and peer into this invisible realm?

One of greatest minds of our time. I always enjoy his ideas!

The Space Elevator will reduce the cost of getting from earth to space. It will also allow us to take very large payloads into space very easily, very safely. Because of that, we can build cities on the moon. We can build space stations. We can build large solar arrays in space to collect energy from the sun and beam it down to earth.

How would space elevator affect the average person?
