A rare treat: cutting-edge science combined with a perceptive portrait of the people who perform it. Dressler (Astronomy/Carnegie Institution) was one of a team that set out to perform a survey of elliptical galaxies and ended by revising a fundamental axiom of modern cosmology. The ``Seven Samurai,'' as they became known on the release of their results, combined expertise in observation and theory, bringing an unusual level of astronomical talent to their task. Dressler gives brief biographies of himself and the other team members and devotes considerable space to detailing their personal interactions over the course of the project, providing an unusually candid look at not only what scientists really do, but how they feel about it and about each other. As the data from their survey accumulated, the team's initial goal of discovering clues to the absolute magnitude of distant galaxies began to fade as they realized that a large number of galaxies were traveling at unexpectedly high velocities—1,000 km per hour or more—that could only be explained by the attraction of a huge mass. Equally important, this discovery forced a reconsideration of the assumption that the velocities of distant galaxies are almost entirely due to the expansion of the universe and directly related to their distances from Earth. The implications of the discovery, and its theoretical underpinnings, take up much of the last part of the book, a generally clear overview of current thinking on the origins of the universe. A readable and engaging glimpse behind the facade of contemporary science; Dressler does for astronomy what James D. Watson's The Double Helix did for molecular biology.

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.
