I’m fascinated by the huge disruptions that early 20th century discoveries in math and physics caused. The upheaval caused by Heisenberg’s uncertainty principle is definitely one, and this cogent, readable history of it is really satisfying. It’s not technical, but it provides enough explanations to make the conflicts tangible. My understanding of anecdotes like Schrödinger’s cat was really enhanced, and the unresolved philosophical questions raised by quantum mechanics now ring more clearly in my mind.
