During a sequence of meals, the author relates the principal features of physics in easy-to-understand conversations with his wife Beth. Beginning with the studies of motion by Galileo and Newton through to the revolutionary theories of relativity and quantum mechanics in the 20th century, all important aspects of electricity, energy, magnetism, gravity and the structure of matter and atoms are explained and illustrated.The second edition similarly recounts the more recent application of these theories to nanoparticles, Bose–Einstein condensates, quantum entanglement and quantum computers. By including accurate measurements of the Cosmic Microwave Background and supernovae in near and distant galaxies, an understanding of how the universe was formed in an Inflationary Big Bang is now possible. We've also gained a much better picture of the life of stars and how they may turn into red giants, white dwarfs, black holes, neutron stars or pulsars.
