Thought-provoking science videos for curious minds  

1. Journey to the Edge of the Universe
A non-stop voyage from Earth to the edge of the Universe using a single, unbroken shot through the use of spectacular CGI. Building on images taken from the Hubble telescope, Journey to the Edge of the Universe explores the science and history of the cosmos, takes us from the Earth, past the Moon and our neighboring planets, out of our Solar System, to the nearest stars, nebulae and galaxies and beyond - right to the edge of the Universe itself.

2. Computing a Theory of Everything - by Stephen Wolfram
Stephen Wolfram, creator of Mathematica, talks about his quest to make all knowledge computational, searchable, and process-able. His search engine, Wolfram Alpha, has no lesser goal than to model and explain the physics underlying the universe. One of best attempts at going through the major milestones of the history of the universe/planet earth/the human civilization in 20 minutes.

3. The Universe in a Nutshell - by Michio Kaku
Dr. Michio Kaku explores how physicists may shrink the science of the Big Bang and the forces of the universe into an equation as small as Einstein's "e=mc^2." Thanks to advances in string theory, physics may allow us to escape the cold death of the universe, explore the multiverse, and unlock the secrets of existence on higher dimensions. While firing up our imaginations about the future, Kaku also presents a succinct history of physics and makes a compelling case for why physics is the key to pretty much everything.

4. The Elegant Universe - by Brian Greene
Brian Greene peels away layers of mystery to reveal a multi-universe that consists of eleven dimensions, where the fabric of space tears and repairs itself, and all matter from the smallest quarks to the most gargantuan supernovas is generated by the vibrations of microscopically tiny loops of energy. The Elegant Universe makes some of the most sophisticated concepts ever contemplated accessible and thoroughly entertaining, bringing us closer than ever to understanding how the universe works.

5. A Universe from Nothing - by Lawrence Krauss
Physicist Lawrence Crauss explains how virtual particles constantly pop in and out of vacuum space, uses that along with the distribution of mass and energy within the universe, and the geometry of space-time, to show how it is mathematically more plausible to have something rather than nothing. Crauss maintains an entertaining story-telling while tackling some of the biggest questions about the origins and the future of the universe.

6. Science can answer moral questions - by Sam Harris
Questions of good and evil, right and wrong are commonly thought t be outside of science. But Sam Harris argues that science can -- and should -- be at the authority of moral issues, shaping human values and setting out what constitutes a good life and a good society.

7. A Tribute to Euler - by William Dunham
Professor William Dunham examines the genius of one of the world's most prolific mathematicians, Leonhard Euler (1707-1783), the genius who produced an astonishing 25,000 pages of pure and applied mathematics of the very highest quality. In this talk, Dunham sketches Euler's life and describes a few of his contributions to a long list of branches of mathematics, including how Euler dominates the top 10 chart of mathematic's most beautiful equations.

8. Beautiful Equations - by Matt Collings
Artist and writer Matt Collings asks top scientists to help him understand five of the most famous equations in science. He talks to Stephen Hawking about his equation for black holes, discovers why Newton was right about those falling apples, and how to make sense of E=mc2. As he gets to grips with these equations he wonders whether the concept of artistic beauty has any relevance to the world of physics.

9. The Drake Equation - Frank Drake
How can we estimate the number of technological civilizations that might exist in our galaxy?  Astronomer Frank Drake conceived an approach to bound the terms involved in estimating such number. The Drake Equation, as it has become known, was first presented in 1961. Although there is no unique solution to this equation, it is a generally accepted and used by the scientific community as tool to examine similar subjects in astronomy.
