In this "entertaining medical series" (The Sunday Times, U.K.), Dr. Michael Mosley shows how drugs have revolutionized medicine and changed the course of human history. Unfolding over a period of 200 years, it's an extraordinary tale of daring, self-experimentation, revelation, genius, and outright luck.

A look at three key numbers that clarify the important questions on climate change, giving a unique perspective on what we know about the past, present and future of our climate.

Engineer Jem Stansfield is used to creating explosions, but in this programme he uncovers the story of how we have learnt to control them and harness their power for our own means. From recreating a rather dramatic ancient Chinese alchemy accident to splitting an atom in his own home-built replica of a 1930s piece of equipment, Jem reveals how explosives work and how we have used their power throughout history. He goes underground to show how gunpowder was used in the mines of Cornwall, recreates the first test of guncotton in a quarry with dramatic results and visits a modern high explosives factory with a noble history. Ground-breaking high speed photography makes for some startling revelations at every step of the way.
