PARADOX

THE NINE GREATEST ENIGMAS IN PHYSICS

An often-entertaining introduction to basic principles of science and philosophy.

A British physicist looks at some of the enigmatic propositions created by his colleagues over the ages.

Al-Khalili (Quantum Physics/Univ. of Surrey; The House of Wisdom: How Arabic Science Saved Ancient Knowledge and Gave Us the Renaissance, 2011, etc.) begins with a few “warm-ups” including “The Game Show Paradox,” in which a contestant considers three doors, one of which conceals a prize. After the contestant chooses one, the host then opens another, which proves not to be the winner, and asks the contestant if she would like to change her choice. In defiance of common sense, it is advantageous to do so; Al-Khalili summarizes the probabilities behind the puzzle. Some of the greatest logical puzzles were the work of the Greek philosopher Zeno, who seemed to prove that motion is impossible. His demonstration seemed annoyingly irrefutable until the development of mathematical tools, such as calculus, for describing change over time. Olbers’ Paradox, on the other hand, revealed deep truths about the universe by asking why the sky is dark at night. Maxwell’s Demon, an imaginary creature that can control individual molecules to overthrow entropy, raises similarly deep issues of fundamental physics. Possibly the most familiar paradox of quantum theory is Schrodinger’s Cat, whose life and death depends on the decay of a radioactive atom in a given stretch of time. Fermi’s Paradox is another that raises questions about the larger universe: If technologically advanced civilizations are common in the universe, why haven’t they visited us? Al-Khalili gives detailed answers to each of these, plus several that grow out of Einstein’s theory of relativity and the possibility of time travel. He ends with a list of unsolved problems of science and a look at the recent question about whether neutrinos have been found to travel faster than light.

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.

THE MAKING OF THE ATOMIC BOMB

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.
