Dr Helen Czerksi explores the extraordinary science of heat. She reveals how heat is the hidden energy contained within matter, with the power to transform it from one state to another. Our ability to harness this fundamental law of science has led to some of humanity's greatest achievements, from the molten metals that enabled us to make tools, to the great engines of the Industrial Revolution powered by steam, to the searing heat of plasmas that offer almost unlimited power.

Jim Al-Khalili investigates the amazing science of gravity, recreating groundbreaking experiments, including the moment when Galileo first worked out how to measure it. He investigates gravity waves, finds out from astronauts what it's like to live without gravity, sets out to find where in Britain gravity is weakest and so where we weigh the least, and helps design a smartphone app that volunteers use to demonstrate how gravity affects time and makes us age at slightly different rates.

Physicist Jim Al-Khalili routinely deals with the strangest subject in all of science - quantum physics, the astonishing and perplexing theory of sub-atomic particles. But now he's turning his attention to the world of nature. Can quantum mechanics explain the greatest mysteries in biology?
How studying the atom forced us to rethink the nature of reality itself.
Nuclear energy might be a failed experiment. In over sixty years the technology has not only failed to keep its promise of cheap, clean and safe energy, it also caused major catastrophes and enabled more nuclear weapons while the nuclear waste problem is still not solved.
