Why does it appear, that humanity is the lone intelligence in the universe? The answer might be that planet Earth is more unique than we've previously assumed. The rare earth hypothesis posits exactly this - that a range of factors made...

This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it's gravity, curved space) through to the concepts of how curved spacetime is represented by psuedo-Riemannian manifolds with...

The general uncertainty principle, about the concentration of a wave vs the concentration of its fourier transform, applied to two non-quantum examples before showing what it means for the Heisenberg uncertainty principle.

Armed with a sense of humor and laypeople's terms, Nobel winner Murray Gell-Mann drops some knowledge on TEDsters about particle physics, asking questions like, Are elegant equations more likely to be right than inelegant ones?

Worried about black holes? Consider this: Every time you accelerate - you generate an event horizon behind you. The more you accelerate away from it the closer it gets. Don't worry, it can never catch up to you, but the Unruh radiation...

As the year 1905 began, Albert Einstein faced life as a "failed" academic. Yet within the next twelve months, he would publish four extraordinary papers, each on a different topic, that were destined to radically transform our...

What can we learn from the world's most enduringly creative people? They "slow-motion multitask," actively juggling multiple projects and moving between topics as the mood strikes -- without feeling hurried. Author Tim Harford shares how...

This video is chapter 7 in my series on special relativity, and it covers the idea that some things AREN'T relative: there IS a sense of absolute length and absolute time, which can be agreed upon from all moving perspectives (as...

The idea that the Moon is a blown-off chunk of the Earth is known as the giant impact hypothesis - but the presence of carbon on the Moon throws this hypothesis into question.

This video is chapter 2 in my series on special relativity, and it covers spacetime diagrams, rotational and translational symmetry of both time and space, how certain transformations preserve distances (measured in terms of a...

This video is about how terrestrial muons are part of our experimental proof of time dilation, length contraction, and special relativity in general.
