A complex but ultimately rewarding exploration of the weird world of quantum physics, which describes the behavior of atomic and subatomic particles.
For example, light moves in both waves and particles, depending on the experiment. Quantum measurements can’t precisely locate a particle such as an electron, and a researcher can only give statistical odds that it’s in a particular spot (anywhere in the universe!). Einstein detested this idea, insisting that the description of light is wrong and that every electron is someplace. In his first book in English, Austrian physicist Zeilinger (Physics/Univ. of Vienna) defends the majority view: Quantum descriptions seem bizarre, but that’s the reality. Treading carefully, the author introduces two college freshmen, Bob and Alice, eager for a taste of quantum physics. Obligingly, their professor places each in distant rooms with a detector connected to a central source that emits light particles that trigger both detectors. Their assignment is to explain what’s happening—not a simple goal because each pair of photons is “entangled,” a quantum concept that means they are linked no matter how far they are separated. A change in one is instantly reflected in the other. Einstein dreamed up entanglement in 1935, explaining that it’s consistent with quantum laws but so absurd that it shows the theory’s defects. Amazingly, experiments proved that entanglement not only exists but has practical applications in computing, cryptography and even teleportation—of subatomic particles. Zeilinger uses simple diagrams and cheerful dialogues between Bob and Alice to make a difficult concept somewhat less difficult.

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.
