Every moment of every day we live in a world created by science. But the story of how we got here is much more than a simple tale of breakthroughs, genius and men jumping out of baths shouting 'Eureka!' History of Science shows how the political upheavals of history combine with iconic inventions and discoveries, along with the ideas of great thinkers, to create the advances that have transformed our lives. Each episode starts with a disarmingly simple question that everyone asks, and then delves into the past, uncovering human stories and recreating the great experiments of the men and women who sought the answers and, in doing so, changed the world. Discover how science has found out what we are made of; where we came from; and what exists beyond Earth. Find out how science revealed the hidden secrets of nature; how it provided the force to topple kings and emperors; and how it unleashed untold power from within our planet. It's the story of how history made science, and science made history, and how the ideas that emerged made the modern world.
