Science-Videos

Series from Channel 4 featuring Sir Martin Rees.

 

There is a fundamental chasm in our understanding of ourselves, the universe, and everything. To solve this, Sir Martin takes us on a mind-boggling journey through multiple universes to post-biological life. On the way we learn of the disturbing possibility that we could be the product of someone elses experiment.

Robbert Dijkgraaf's focus is on string theory, quantum gravity, and the interface between mathematics and particle physics, bringing them together in an accessible way, looking at sciences, the arts and other matters.

Slow Motion video of bullet impacts made by Werner Mehl from Kurzzeit. These are by far the best slow motion bullet impacts available anywhere. Watch for the hollow point rounds in the ballistics gel.

Questions of Fundamental Physics to be answered this century:

 

Why are there three forces of nature due to local symmetry?

Why is alpha = 1/137.036999708...?

Why are there families of quarks and leptons?

Why is space three dimensional and are there hidden dimensions?

Why should you bother to wake up tomorrow knowing that we're all going to die billions and billions of years from now when the universe turns to absolute zero, when the stars blink out, when we have nothing but neutron stars and black holes? Dr. Kaku says that billions of years from now we may be able to move to a different universe.

Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look "around" corners or see inside the body without X-rays.

The Japanese artist Isao Hashimoto has created a beautiful, undeniably scary time-lapse map of the 2053 nuclear explosions which have taken place between 1945 and 1998, beginning with the Manhattan Project's "Trinity" test near Los Alamos and concluding with Pakistan's nuclear tests in May of 1998. This leaves out North Korea's two alleged nuclear tests in this past decade (the legitimacy of both of which is not 100% clear).
