The Clash of the Titans

The first of three programmes in which nuclear physicist Professor Jim Al-Khalili tells the story of the greatest scientific discovery ever - that everything is made of atoms.

As scientists delved deep into the atom, into the very heart of matter, they unravelled nature's most shocking secrets. They had to abandon everything they believed in and create a whole new science, which today underpins the whole of physics, chemistry, biology and maybe even life itself.

The series tells a story of geniuses like Albert Einstein and Werner Heisenberg who were driven by their thirst for knowledge and glory. It is a story of false starts and conflicts, ambition and revelation, a story which leads us through some of the most exciting and exhilarating ideas ever conceived by the human race.
