A staggering account of the scientific revolution that still challenges our notions of reality.
Wired UK consulting science editor Kumar (Science and the Retreat from Reason, 1997) provides a gripping narrative of the birth of atomic physics in the first half of the 20th century. Max Planck described his 1900 discovery—that light acted on matter in packets of energy rather than continuous waves—as “simply an act of desperation.” Nonetheless, his discovery was an outgrowth of technological problems faced by the burgeoning German lighting industry. In 1905, Albert Einstein, another of the fathers of quantum physics (as well as relativity theory), pointed the way to the discovery of the photoelectric effect and the development of lasers by relating the frequency of light waves to photon energy. However, years later he wrote that quantum physics reminded him “a little of the system of delusions of an exceedingly intelligent paranoic, concocted of incoherent elements of thoughts.” Other puzzling discoveries led Niels Bohr to identify isotopes and to recognize that radioactivity was a fundamentally unpredictable nuclear rather than atomic phenomenon. In 1925, Bohr’s younger associate Werner Heisenberg had a flash of insight that transformed the seemingly paradoxical nature of the new physics and with it called into question the nature of objective reality—it is impossible, he wrote, to achieve a simultaneously exact measurement of quantum physical parameters such as the position and momentum, or the time and energy of a nuclear-scale event. Until his death, Einstein opposed Bohr and Heisenberg’s renunciation of the possibility of representing reality “as independent of observation.” The debate still rages today, spawning new areas of research in quantum computing and even teleportation. Kumar evokes the passion and excitement of the period and writes with sparkling clarity and wit.

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

by Richard Rhodes ‧ RELEASE DATE: Feb. 1, 1986
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.
