A solid case for taking better care of the ground on which we stand.
An Australian sheepherder and range specialist looks at his home’s biotic communities and how to improve their health with a more thoughtful kind of agriculture.
Arachnophobes take note: There’s a reason you want to see a lot of spiders in the tall grass, for, as Massy (Breaking the Sheep’s Back, 2011, etc.) instructs, it means that good things are happening. “To sustain millions of spiders,” he writes, “there must be a corresponding diversity in the food chain, and healthy landscape function above and below ground.” Such a healthy landscape, argues the author in considerable detail, cannot come about through what he calls the “more-on” approach to agriculture, piling chemicals atop increasingly unproductive soil, but instead is the result of a “regenerative” agriculture that necessarily happens at a small scale. The larger scale is what modern agronomists insist is needed in order to feed a growing world population, but at a cost that may be too great. As Massy observes, a livestock grower will always seek to save the herd before saving the range, no matter how shortsighted that strategy may be in the end. The author’s prose can be arid and technical at times, as when he writes, “at a global level, non-regeneratively grazed livestock emissions are a huge source of anthropogenic greenhouse gas emissions.” At others, he sounds like a modern butterflies-are-free avatar of Charles Reich: “an Emergent mind combines elements of the previous Organic and Mechanical minds, but its true difference is an openness to the ongoing processes of emergence and self-organization." The circularity aside, Massy’s book is a useful small-is-beautiful argument for appropriate-level farming that people can do without massive machines or petrochemical inputs. Though less elegant than Wendell Berry and Wes Jackson, he certainly falls into their camp, and their readers will want to know Massy’s work as well.

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.

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.
