Only the longest threads

Dramatic and lucid accounts of six monumental breakthroughs in physics—Newton's universal laws of motion and gravitation, electromagnetism, relativity, quantum mechanics, quantum field theory, and string theory—each told from the viewpoint of a (fictional) witness to the events. A tour de force of science made accessible. Tasneem Zehra is a Pakistani theoretical physicist. She obtained her PhD in theoretical physics from Stockholm University in 2003, after which she went to Harvard University for a two-year postdoctoral research position. She lives in Cambridge, Massachusetts.
