AT THE EDGE OF TIME

EXPLORING THE MYSTERIES OF OUR UNIVERSE’S FIRST SECONDS

A fine history of the universe from the Big Bang to the present.

Hooper (Astronomy and Astrophysics/Univ. of Chicago Nature’s Blueprint: Supersymmetry and the Search for a Unified Theory of Matter and Force, 2009, etc.), a senior scientist in the Theoretical Astrophysics Group at Fermilab, explains that the Big Bang is simply the consequence of rewinding time in today’s universe, which is expanding and cooling. As time moves backward, the cosmos shrinks and becomes hotter until, 13.8 billion years ago, according to calculations, it becomes infinitely small and infinitely hot. During that early period, “matter likely interacted in ways that it no longer does, and space and time themselves may have behaved differently than they do in the world that we know.” Nothing existed except a uniform soup. Since Einstein—whose theory of relativity provides the science behind the Big Bang—proved that matter and energy are equivalent, the particles that make up matter did not yet exist. After a few millionths of a second, the universe cooled enough for familiar subatomic particles (protons, neutrons, electrons) to form, but it remained too hot for these to combine. The universe was dark because charged particles (i.e., protons and electrons) soak up light. At 380,000 years ago, the temperature had dropped enough for these to combine into atoms. The universe became electrically neutral, and light spread everywhere; it is still present in the cosmic microwave background. Stars, galaxies, and planets followed. Progress in cosmology has increased our ignorance as well as our knowledge. A good sport, Hooper seems positively excited as he describes the discoveries of dark matter and dark energy, which reveal that everything we observe represents less than 5% of the universe. Beginning with Carl Sagan’s Cosmos in 1980, Big Bang books have become a genre that curious readers should check out every few years to keep up with breakthroughs (gravity waves being the latest). They can’t go wrong with Hooper’s.

A lucid account that is neither dumbed down nor overly difficult.

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.

LAB GIRL

Award-winning scientist Jahren (Geology and Geophysics/Univ. of Hawaii) delivers a personal memoir and a paean to the natural world.

The author’s father was a physics and earth science teacher who encouraged her play in the laboratory, and her mother was a student of English literature who nurtured her love of reading. Both of these early influences engrossingly combine in this adroit story of a dedication to science. Jahren’s journey from struggling student to struggling scientist has the narrative tension of a novel and characters she imbues with real depth. The heroes in this tale are the plants that the author studies, and throughout, she employs her facility with words to engage her readers. We learn much along the way—e.g., how the willow tree clones itself, the courage of a seed’s first root, the symbiotic relationship between trees and fungi, and the airborne signals used by trees in their ongoing war against insects. Trees are of key interest to Jahren, and at times she waxes poetic: “Each beginning is the end of a waiting. We are each given exactly one chance to be. Each of us is both impossible and inevitable. Every replete tree was first a seed that waited.” The author draws many parallels between her subjects and herself. This is her story, after all, and we are engaged beyond expectation as she relates her struggle in building and running laboratory after laboratory at the universities that have employed her. Present throughout is her lab partner, a disaffected genius named Bill, whom she recruited when she was a graduate student at Berkeley and with whom she’s worked ever since. The author’s tenacity, hope, and gratitude are all evident as she and Bill chase the sweetness of discovery in the face of the harsh economic realities of the research scientist.

Jahren transcends both memoir and science writing in this literary fusion of both genres.
