Who decided there were 60 seconds in a minute and how do we know there are five trillion trillion bacteria on Earth? These and many more questions are tackled by Professor William Bynum in A Little History of Science. Bynum tells the history of science through the surprising and personal stories of scientists. He recounts the change in our understanding of the stars, looks beneath the surface of the planet, follows the evolution of chemistry and introduces the physics that explains gravity, electricity and the structure of the atom.
Bynum is professor emeritus, history of medicine, University College London. He is author of many works including the recent Great Discoveries in Medicine.
