Book: Entanglement: The Greatest Mystery in Physics

Entanglement: The Greatest Mystery in Physics
Picture from Amazon

Some light reading for a quantum physics post-doc. Inaccessible for most.
284 pages, ★★★

The topic is fascinating. Entangled photons (light ‘particles’) are known to exhibit what Einstein famously called “spooky action-at-a-distance”. Entangled photons exist in every possible state (and even in every possible position) until one of them is observed. The observation of one of the photons, no matter how far away it has travelled, instantly (literally instantly—at infinite speed—not just at the speed of light) influences the other photon by deciding its ‘state’. This has puzzled physicists for decades and has started to fascinate the public in recent years.

However, this book is inaccessible for me. I haven’t studied physics to this high a level. Its diagrams are incomprehensible for me because I’m not familiar with the symbols—and the book, foolishly, doesn’t define them. There are no analogies to help me understand these weird phenomena, and the characters (e.g. Einstein) don’t come to life to the extent that they do in Michio Kaku’s books. Entanglement makes light holidaying read for an established quantum physicist but is inaccessible and irrelevant to most other people. Fails to engage the public. ★★★
