A POSITRON NAMED PRISCILLA

SCIENTIFIC DISCOVERY AT THE FRONTIER

Capitalizing on an annual forum to showcase young investigators, the prestigious National Academy of Sciences is publishing science-writer versions of ``frontier'' research in 10 fields ranging from particle physics to AIDS. The writers are seasoned pros—prize-winning book or magazine authors and editors or correspondents for science journals. Frequently they also hold degrees—e.g., in engineering (T.A. Heppenheimer) or geology (Elizabeth Maggio) or physics (Marcia Bartusiak). Should be a winning combination, no? Not entirely, for a couple of reasons: Sometimes the writing is pitched too high for the general reader (Scientific American is clearly the model). Sometimes it is the nature of the subject: Fourier analysis and Fourier transforms are wondrous things of beauty in mathematics, but their extension to signal processing and wavelet analysis may leave the reader who has only elementary familiarity with sine and cosine curves floundering. Finally, the very frontier under discussion is frustrating: Do we really need to know, thanks to many space probes and samplings, that, ``no matter which hypothesis you mention, Venus maddeningly seems to offer both support and contradiction''? Having said that, let us acknowledge praiseworthy chapters. Certainly the title piece: It is all about the scanning tunneling microscope that allows investigators to trap and photograph atoms and elementary particles—Priscilla the positron for one. That same instrument has revealed the charms of fullerenes—the new soccer-ball shaped form of carbon (named after Buckminster Fuller's geodesic domes) that Science named Molecule of the Year in 1991. Finally, the chapter on AIDS offers one of the clearest expositions on the nature of HIV and its insidious undermining of the immune system. Chapters on earthquake prediction, protein folding, DNA duplication, the search for the top quark, and the nature of the sun's deepest interior provide intriguing clues, if not the last roundup, on frontier science.

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.

THE ORDER OF TIME

As much a work of philosophy as of physics and full of insights for readers willing to work hard.

Undeterred by a subject difficult to pin down, Italian theoretical physicist Rovelli (Reality Is Not What It Seems: The Journey to Quantum Gravity, 2017, etc.) explains his thoughts on time.

Other scientists have written primers on the concept of time for a general audience, but Rovelli, who also wrote the bestseller Seven Brief Lessons on Physics, adds his personal musings, which are astute and rewarding but do not make for an easy read. “We conventionally think of time,” he writes, “as something simple and fundamental that flows uniformly, independently from everything else, uniformly from the past to the future, measured by clocks and watches. In the course of time, the events of the universe succeed each other in an orderly way: pasts, presents, futures. The past is fixed, the future open….And yet all of this has turned out to be false.” Rovelli returns again and again to the ideas of three legendary men. Aristotle wrote that things change continually. What we call “time” is the measurement of that change. If nothing changed, time would not exist. Newton disagreed. While admitting the existence of a time that measures events, he insisted that there is an absolute “true time” that passes relentlessly. If the universe froze, time would roll on. To laymen, this may seem like common sense, but most philosophers are not convinced. Einstein asserted that both are right. Aristotle correctly explained that time flows in relation to something else. Educated laymen know that clocks register different times when they move or experience gravity. Newton’s absolute exists, but as a special case in Einstein’s curved space-time. According to Rovelli, our notion of time dissolves as our knowledge grows; complex features swell and then retreat and perhaps vanish entirely. Furthermore, equations describing many fundamental physical phenomena don’t require time.

As much a work of philosophy as of physics and full of insights for readers willing to work hard.
