The Age of Entanglement: When Quantum Physics Was Reborn
Why this book?
Guilder uses historical vignettes to describe how entanglement came to be regarded as a – or perhaps the – central pillar of quantum physics. For example, we share a streetcar ride through Copenhagen in 1923 with Niels Bohr, Albert Einstein, and Arnold Sommerfeld. Although we don't know precisely what they discussed, Guilder indicates what they probably discussed based on quotations from letters and other evidence. Thus, the book reads like a historical novel. It centers on the distant correlations, dubbed (by Einstein and Erwin Schrodinger) "spooky action at a distance." Since 1964, physicists have shown this astonishing phenomenon, now called "non-locality," to be clearly predicted by quantum theory and fully confirmed by experiment. This development is the "rebirth" of quantum physics referred to in the title. Guilder is a non-scientist who writes beautifully with a good grasp of physics.
