A useful introduction to the history of quantum theory for scientifically inclined readers.
A historical exploration of quantum physics, which “predicts a stunning variety of phenomena to an extraordinary degree of accuracy.”
The realm of quantum physics is extremely difficult to comprehend. According to Niels Bohr’s “Copenhagen interpretation,” largely devised in the 1920s, subatomic particles have no definite properties until they are measured. One can only calculate the probability of a certain result—for example, the location of an electron—and the very act of measurement changes matters. In his first book, astrophysicist and science writer Becker agrees with a minority of physicists that quantum physics needs a better interpretation “because it’s not immediately clear what the theory is saying about the world. The mathematics of quantum physics is unfamiliar and abstruse, and the connection between the mathematics and the world we live in is hard to see.” Until his death, Einstein insisted that this bizarre picture couldn’t be correct, but most colleagues disagreed. Becker summarizes the debate and then takes up the cudgel. Einstein’s objections never caught on, but successors have had some success. David Bohm and Hugh Everett maintained that particles have specific properties and locations, but they also introduced complex concepts such as nonlocality, hidden variables, and a many-worlds view. The leading genius was John Bell, whose 1964 theorem postulates certain phenomena that violate traditional quantum theory. Subsequent extremely delicate experiments proved him right. Quantum physics works, so most physicists don’t concern themselves with its view of reality, and the debate rarely reaches popular media. It’s a philosophical question whose major figures are not household names and whose arguments do not simplify matters. The author works diligently to introduce them to a lay audience. Readers must put in the effort, but those who persist will come away with a taste of a basic scientific issue that a century of controversy has yet to resolve.

Italian theoretical physicist Rovelli (General Relativity: The Most Beautiful of Theories, 2015, etc.) shares his thoughts on the broader scientific and philosophical implications of the great revolution that has taken place over the past century.
These seven lessons, which first appeared as articles in the Sunday supplement of the Italian newspaper Sole 24 Ore, are addressed to readers with little knowledge of physics. In less than 100 pages, the author, who teaches physics in both France and the United States, cogently covers the great accomplishments of the past and the open questions still baffling physicists today. In the first lesson, he focuses on Einstein's theory of general relativity. He describes Einstein's recognition that gravity "is not diffused through space [but] is that space itself" as "a stroke of pure genius." In the second lesson, Rovelli deals with the puzzling features of quantum physics that challenge our picture of reality. In the remaining sections, the author introduces the constant fluctuations of atoms, the granular nature of space, and more. "It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy—or in our physics,” he writes. Rovelli also discusses the issues raised in loop quantum gravity, a theory that he co-developed. These issues lead to his extraordinary claim that the passage of time is not fundamental but rather derived from the granular nature of space. The author suggests that there have been two separate pathways throughout human history: mythology and the accumulation of knowledge through observation. He believes that scientists today share the same curiosity about nature exhibited by early man.

BOOK REVIEW
A magnificent account of a central reality of our times, incorporating deep scientific expertise, broad political and social knowledge, and ethical insight, and Idled with beautifully written biographical sketches of the men and women who created nuclear physics. Rhodes describes in detail the great scientific achievements that led up to the invention of the atomic bomb. Everything of importance is examined, from the discovery of the atomic nucleus and of nuclear fission to the emergence of quantum physics, the invention of the mass-spectroscope and of the cyclotron, the creation of such man-made elements as plutonium and tritium, and implementation of the nuclear chain reaction in uranium. Even more important, Rhodes shows how these achievements were thrust into the arms of the state, which culminated in the unfolding of the nuclear arms race. Often brilliantly, he records the rise of fascism and of anti-Semitism, and the intensification of nationalist ambitions. He traces the outbreak of WW II, which provoked a hysterical rivalry among nations to devise the bomb. This book contains a grim description of Japanese resistance, and of the horrible psychological numbing that caused an unparalleled tolerance for human suffering and destruction. Rhodes depicts the Faustian scale of the Manhattan Project. His account of the dropping of the bomb itself, and of the awful firebombing that prepared its way, is unforgettable. Although Rhodes' gallery of names and events is sometimes dizzying, his scientific discussions often daunting, he has written a book of great drama and sweep. A superb accomplishment.
