Discovering the Elements

Just 92 elements made up the world, but the belief that were only four - earth, fire, air and water - persisted until the 19th Century. Professor Al-Khalili retraces the footsteps of the alchemists who first began to question the notion of the elements in their search for the secret of everlasting life. He reveals the red herrings and rivalries which dogged scientific progress, and explores how new approaches to splitting matter brought us both remarkable elements and the new science of chemistry.

What is our Future?

In a powerful conclusion, Brian pieces together this story of creation that started with what Einstein called the 'happiest thought of his life' - the moment that he realised that gravity was far stranger than anyone had imagined. In an incredible experiment inside the largest vacuum chamber, Brian reveals how Einstein formulated a new theory of gravity, which ultimately took us back to the big bang. And how in doing so, we humans found our true place in space and time.

We have a relationship with few things in nature the way we do with snow: we hate it, we love it, and we think we understand it. But we barely know the contradictory and beautiful components of snow’s character. But that’s something scientists are changing. From the formation of single flakes to the howling 70 km/h winds of lake effect snow storms to the destructive power of avalanches, intrepid researchers are bringing snow science into the 21st Century.
