CHARGE: Why Does Gravity Rule?

Frank Close delves into fundamental particles and forces to find clues to a deep unsolved mystery of physics: why is matter neutral? Human beings have long been aware of the electric and magnetic forces around us, from the electrostatic charge built up by rubbing amber with fur, to the pull of the lodestone, and scientific investigation showed that the two are intimately connected, as electromagnetism. Lightning shows how devastating electricity can be in nature, while humans learned to exp...
