A delightful addition to a widespread, ongoing scientific debate.
A striking examination of an important scientific question: “What, exactly, are scholars of fundamental physics today trying to achieve?”
A former editor of Science and Nature, Lindley (Uncertainty: Einstein, Heisenberg, Bohr, and the Struggle for the Soul of Science, 2007, etc.) expressed unhappiness with his profession in The End of Physics (1993). Since then, matters have changed without actually improving, so he returns to the attack. He maintains that today’s theoreticians have reverted to a pre-modern way of thinking that harks back to the ancient Greeks, who are regarded, incorrectly, as the founders of modern science. Led by Plato, they belittled observation because human senses are imperfect. Greek thinkers believed that true knowledge required reason and logic. They also had a profound respect for mathematics, which they did not consider a useful tool but a source of deep insights. “Fundamental physics has [become] a version of philosophy…one that shares with other areas of philosophical inquiry an endless capacity to ask deep questions and an impressive inability ever to answer them.” Lindley makes his case through a fine capsule history of physical science with an emphasis on Galileo, in the opinion of many the first modern scientist. Galileo looked around, wondered about phenomena (do heavy things fall faster than light things?), performed experiments, and calculated. He produced groundbreaking discoveries, as did his followers, from Newton to Maxwell to Einstein to the founders of quantum mechanics. Lindley believes that physics peaked in the 1970s with the development of the standard model, an excellent if imperfect explanation of fundamental particles and forces. Since then, he adds, researchers have attacked still unexplained problems (dark matter, dark energy) with complex mathematics-based systems (supersymmetry, string theory), some of whose predictions are untestable. He joins a minority of colleagues who complain that a 30-year obsession with pure mathematics has reached a dead end, although the physics establishment remains convinced that deep insights are just around the corner. This scientific polemic deserves mention alongside Sabine Hossenfelder’s Lost in Math (2018).

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.
