A theoretical physicist delivers an entertaining attack on her profession, arguing that it has fallen in love with theories that bear little relation to reality.
In her first book for a popular audience, a “story of how aesthetic judgment drives contemporary research,” Hossenfelder (editor: Experimental Search for Quantum Gravity, 2017), a research fellow at the Frankfurt Institute for Advanced Studies in Germany, expresses despair that the golden age of physics ended with her parents’ generation. By the 1970s, a torrent of Nobel Prizes went to physicists who unified a confusing mélange of subatomic particles into the elegant standard model and did the same for three out of four fundamental forces. While a brilliant achievement, the standard model failed to answer basic questions such as the nature of dark matter and energy, matter-antimatter asymmetry, and the impossibility of quantizing gravity. The author maintains that fashionable new theories addressing these issues are preoccupied with beauty and naturalness to the neglect of actual observation. Thus, supersymmetry solves several problems by predicting dozens of new subatomic particles that the most powerful accelerators have failed to find. String theory seems to explain almost everything, but its basis is pure mathematics, and its postulates are untestable by any conceivable technology. “I can’t believe what this once-venerable profession has become,” writes Hossenfelder. “Theoretical physicists used to explain what was observed. Now they try to explain why they can’t explain what was not observed. And they’re not even good at that….But there are so many ways not to explain something.” A take-no-prisoners interviewer, the author asks pointed questions of the giants of physics and is not shy about arguing with them.
Even educated readers will struggle to understand the elements of modern physics, but they will have no trouble enjoying this insightful, delightfully pugnacious polemic about its leading controversy.Pub Date: June 12, 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.
An intriguing meditation on the nature of the universe and our attempts to understand it that should appeal to both scientists and general readers.Pub Date: March 1, 2016

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.
