Great Mysteries of Physics Podcast
1) Theory of everything: do we really need one?
The quest for a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. While each of our main theories of physics works extraordinarily...Show More
2) Will we ever have a fundamental theory of life and consciousness?
What’s the difference between a living collection of matter, such as a tortoise, and an inanimate lump of it, such as a rock? They are, after all, both just made up of non-living atoms. The truth is, ...Show More
