TERRA

OUR 100-MILLION-YEAR-OLD ECOSYSTEM—AND THE THREATS THAT NOW PUT IT AT RISK

Dense, but useful and up-to-date.

An authoritative history of our planet’s evolution.

Paleontologist Novacek (Time Traveler: In Search of Dinosaurs and Ancient Mammals from Montana to Mongolia, 2001, etc.), science provost at the American Museum of Natural History, seeks to help readers understand Earth’s past, the rise of the modern ecosystem and why human beings must act now to stem the damage they are inflicting on the environment. The world as we know it emerged 100 million years ago, he writes, with the appearance of the first flowering plants in the time of the dinosaurs (the Cretaceous period). Drawing on his own field work and recent discoveries in the fossil record, he describes in rich detail the biological processes that gave rise to the lush biota of the modern world. Pollination, for example, has produced wondrous flora in places from Sayreville, N.J., which has yielded fossilized plant parts from the Cretaceous, to present-day Vietnam, where forests and marshes harbor nearly 900 identified species of orchids. About 65 million years ago, he writes, the early flowering world was devastated when a Mount Everest–sized rock traveling at 22,000 miles per hour crashed into the Yucatan. The thermal blast kept temperatures at 1,300 degrees Fahrenheit for hours and led to the mass extinction of 70 percent of land and sea species, including the dinosaurs. The greatest subsequent threat to biodiversity has been Homo sapiens, who appeared seven million years ago, began cultivating crops and have increasingly damaged the planet ever since through land degradation, overexploitation, invasive species and pollution. This overlong book will appeal especially to readers who share his fascination with the minutiae of biological connections: “nearly nine hundred bird species (including three hundred hummingbirds!) are pollinators.” The author also duly notes that we have the capacity but may lack the will and international leadership to slow the planet’s biological decline.

Dense, but useful and up-to-date.

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.

A SHORT HISTORY OF NEARLY EVERYTHING

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science...

Bryson (I'm a Stranger Here Myself, 1999, etc.), a man who knows how to track down an explanation and make it confess, asks the hard questions of science—e.g., how did things get to be the way they are?—and, when possible, provides answers.

As he once went about making English intelligible, Bryson now attempts the same with the great moments of science, both the ideas themselves and their genesis, to resounding success. Piqued by his own ignorance on these matters, he’s egged on even more so by the people who’ve figured out—or think they’ve figured out—such things as what is in the center of the Earth. So he goes exploring, in the library and in company with scientists at work today, to get a grip on a range of topics from subatomic particles to cosmology. The aim is to deliver reports on these subjects in terms anyone can understand, and for the most part, it works. The most difficult is the nonintuitive material—time as part of space, say, or proteins inventing themselves spontaneously, without direction—and the quantum leaps unusual minds have made: as J.B.S. Haldane once put it, “The universe is not only queerer than we suppose; it is queerer than we can suppose.” Mostly, though, Bryson renders clear the evolution of continental drift, atomic structure, singularity, the extinction of the dinosaur, and a mighty host of other subjects in self-contained chapters that can be taken at a bite, rather than read wholesale. He delivers the human-interest angle on the scientists, and he keeps the reader laughing and willing to forge ahead, even over their heads: the human body, for instance, harboring enough energy “to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.”

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science into perspective.
