An examination of the thirst for knowledge by the likes of Albert Einstein and Werner Heisenberg.

Professor Jim Al-Khalili shows how, in our quest to understand the tiny atom, we unravelled the mystery of how the universe was created. A story with dramatic twists and turns, taking in world-changing discoveries like radioactivity, the atom bomb and the Big Bang, as the greatest brains of the 20th century competed to answer the biggest questions of all - why are we here and how were we made.

Al-Khalili shows how the world we think we know turns out to be a tiny sliver of an infinitely weirder universe than which we could have conceived.
