Thought-provoking—and deeply appealing to the inner iconoclast.
A lucid presentation of emergence theory—the way decentralized thinking allows for cannily effective self-organization—from Feed editor-in-chief Johnson (Interface Culture, not reviewed).
“The movement from low-level rules to higher-level sophistication is what we call emergence,” writes Johnson, explaining that local, parallel, cumulatively complex interactions result in some kind of discernable macrobehavior. And that behavior, if adaptive, has the distinctive quality of growing smarter over time. One needn’t be conscious or aware of the process, either, argues Johnson: if learning is considered the absorption and retrieval of information, then, for instance, the topography of a city qualifies as emergent behavior. An ant colony is another good example, where the ants as agents produce behavior that allows for a step in the direction of higher organization—from ants to colonies. Johnson’s clarity is a boon when it comes to explaining such ideas as swarm logic and the way phenomena like critical mass, ignorance, random encounters, pattern recognition, and local attentiveness result in a collective phenomena of remarkable elegance organized from below, without the dubious benefits of hierarchy. Emergence is nothing new, Johnson notes—surely the way in which the guilds organized themselves in 12th-century Florence is an example, let alone how the cells in our bodies act the way they do, for better or worse—but we are now simply recognizing it as a quiet, generative force working in theaters ranging from the slime mold (dissolving and regrouping upon signals from the molecular level) to the negative-positive feedback loops that self-govern sites on the Internet. Examples abound, and Johnson reaps them everywhere, from software design to CNN, where the common pool of news has allowed local networks to choose their own programming, subverting the mother network’s dominance.

A media-savvy scientist cleans out his desk.
Tyson (Astrophysics for People in a Hurry, 2017, etc.) receives a great deal of mail, and this slim volume collects his responses and other scraps of writing.
The prolific science commentator and bestselling author, an astrophysicist at the American Museum of Natural History, delivers few surprises and much admirable commentary. Readers may suspect that most of these letters date from the author’s earlier years when, a newly minted celebrity, he still thrilled that many of his audience were pouring out their hearts. Consequently, unlike more hardened colleagues, he sought to address their concerns. As years passed, suspecting that many had no interest in tapping his expertise or entering into an intelligent give and take, he undoubtedly made greater use of the waste basket. Tyson eschews pure fan letters, but many of these selections are full of compliments as a prelude to asking advice, pointing out mistakes, proclaiming opposing beliefs, or denouncing him. Readers will also encounter some earnest op-ed pieces and his eyewitness account of 9/11. “I consider myself emotionally strong,” he writes. “What I bore witness to, however, was especially upsetting, with indelible images of horror that will not soon leave my mind.” To crackpots, he gently repeats facts that almost everyone except crackpots accept. Those who have seen ghosts, dead relatives, and Bigfoot learn that eyewitness accounts are often unreliable. Tyson points out that extraordinary claims require extraordinary evidence, so confirmation that a light in the sky represents an alien spacecraft requires more than a photograph. Again and again he defends “science,” and his criteria—observation, repeatable experiments, honest discourse, peer review—are not controversial but will remain easy for zealots to dismiss. Among the instances of “hate mail” and “science deniers,” the author also discusses philosophy, parenting, and schooling.

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