THE QUEST TO FIND THE TRUE AGE OF THE UNIVERSE AND THE THEORY OF EVERYTHING

Astrophysicist Gribbin (Erwin Schrodinger and the Quantum Revolution, 2013, etc.) clearly explains how the accidental discovery of "the cosmic microwave background radiation" in the mid-1960s led to the assignment of a definitive date for the origin of the universe.

Despite the fact that physicists have yet to unify quantum physics and relativity into one coherent theory, the author believes that the implications stemming from the discovery that the universe is 13.8 billion years old definitively proves the fundamental correctness of both. “The age of the Universe calculated by cosmologists…is just a tiny bit older than the age of the stars it contains," writes the author. The most profound of these is that our universe is not unchangeably "infinite in time and space." In the 1950s, astrophysicists were divided between those who believed in a steady-state universe (led by Albert Einstein) and proponents of the rival Big Bang theory. One way of resolving the dispute was to accurately determine the densities of galaxies in space. This allowed an inference to be drawn about their development over time. The placement of radio telescopes on satellites, which used photographic plates to build up images of the universe, made this possible. Analysis of the data lent credibility to the Big Bang theory, but it was the chance discovery of pervasive cosmic microwave radiation that decisively tipped the balance in its favor. The 1980s discovery of the existence of dark matter and energy (which exert a gravitational force but are impervious to radiation) has allowed scientists to recalculate the rate of expansion of the universe more precisely to fit the observed data. In order to bring lay readers up to speed, Gribbin first reprises the crucial developments, beginning in the 19th century, that have led scientists to their current understanding.

An exciting chronicle of a monumental scientific accomplishment by a scientist who participated in the measuring of the age of the universe.

THE INCREDIBLE JOURNEY OF PLANTS

A neurobiologist reveals the interconnectedness of the natural world through stories of plant migration.

In this slim but well-packed book, Mancuso (Plant Science/Univ. of Florence; The Revolutionary Genius of Plants: A New Understanding of Plant Intelligence and Behavior, 2018, etc.) presents an illuminating and surprisingly lively study of plant life. He smoothly balances expansive historical exploration with recent scientific research through stories of how various plant species are capable of migrating to locations throughout the world by means of air, water, and even via animals. They often continue to thrive in spite of dire obstacles and environments. One example is the response of plants following the Chernobyl nuclear disaster. Three decades later, the abandoned “Exclusion Zone” is now entirely covered by an enormous assortment of thriving plants. Mancuso also tracks the journeys of several species that might be regarded as invasive. “Why…do we insist on labeling as ‘invasive’ all those plants that, with great success, have managed to occupy new territories?” asks the author. “On a closer look, the invasive plants of today are the native flora of the future, just as the invasive species of the past are a fundamental part of our ecosystem today.” Throughout, Mancuso persuasively articulates why an understanding and appreciation of how nature is interconnected is vital to the future of our planet. “In nature everything is connected,” he writes. “This simple law that humans don’t seem to understand has a corollary: the extinction of a species, besides being a calamity in and of itself, has unforeseeable consequences for the system to which the species belongs.” The book is not without flaws. The loosely imagined watercolor renderings are vague and fail to effectively complement Mancuso’s richly descriptive prose or satisfy readers’ curiosity. Even without actual photos and maps, it would have been beneficial to readers to include more finely detailed plant and map renderings.

An authoritative, engaging study of plant life, accessible to younger readers as well as adults.

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

A SHORT HISTORY OF NEARLY EVERYTHING

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.
