Olson takes a major step in the right direction, but it will be a long journey.
The take-home message of this five-continent trek by science writer Olson (Biotechnology, not reviewed) is that races don’t exist: genetically, we are all sisters and brothers under the skin.
That message has been promulgated in the press and professional literature lately as geneticists track the DNA in the human genome as well as in a cell’s mitochondria. These are the power factories that lie outside the cell nucleus, and we inherit them from our mothers. But Olson raises the level of discourse to a new high, assembling powerful evidence to support the no-races hypothesis. It all begins with “mitochondrial Eve,” member of a band living in east Africa over 100,000 years ago. Her descendants were the modern humans who migrated into Eurasia and, some 7,500 generations later, peopled all parts of the planet. Similarly, humans are descended from a male who passed on his Y chromosome to sons. Opponents arguing for a multiregional origin of mankind posit that different continental groups gave rise to racially distinct humans. Not likely, Olson and his sources counter, citing archaeological, fossil, and particularly biological evidence. Basically, scientists search global DNA samples looking for patterns of mutations that enable the reconstruction of genetic history. Example: A woman who gives birth to two daughters, one with the mother’s intact mitochondrial DNA and one with a single mutation, is the ancestor of two groups of females—one with the intact sequence, the other with the mutated form. These “haplotypes” create “haplogroups,” enabling scientists to trace who went where when. Y chromosome and other gene mutations allow similar analyses—all pointing to diversity, but also to biological identity. There are problems. Why no Neanderthal genes? What to do when researchers who want to study isolated groups or rare remains are accused of “stealing their DNA”? Even armed with the facts, can people ever overcome the cultural hierarchies that impose prejudice, stigma, slavery, genocide?

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.
