Serious mathematics at its intriguing, transporting best.
A wide-ranging sojourn into geometry and how it can be applied to real-life situations.
Even for the math-averse, there is something indelibly “primal” and useful about geometry, at least of the Euclidean variety. As University of Wisconsin math professor Ellenberg is quick to note, however, “geometry is the cilantro of math. Few are neutral.” As the author shows, it’s a subject on the move, providing new insights and deployments. “We are living in a wild geometric boomtown, global in scope,” writes Ellenberg in this often humorous, anecdotally rich dive into numerous mathematical theories. (His accessible approach carries over from How Not To Be Wrong, his 2014 bestseller.) The author feels that geometry has a lot to do with integrity and honesty, but he doesn’t want to sacrifice intuition at the altar of logical deduction: “We start from our intuitions about shapes in the physical world (where else could we start?), we analyze closely our sense of the way those shapes look and move, so precisely that we can talk about them without relying on our intuition if we need to.” Ellenberg introduces readers to a bevy of relatable mathematical concepts: the “theory of the random walk” and its implications regarding the unpredictable nature of the stock market; “tree geometry” and how it might help you win certain games; the algorithms that work their ways into tennis matches and the World Series as well as some that recall a bunch of monkeys at typewriters, “reducing literary texts to a binary sequence of consonants and vowels.” Also eye-opening are the author’s discussions of pandemics—progression, decay, and the math of herd immunity—and how geometric processes can “model smallpox, scarlet fever, train derailments, and steam boiler explosions.” In the penultimate chapter, “How Math Broke Democracy (and Might Still Save It),” Ellenberg offers an engrossing discussion of how geometry can help in the fight against gerrymandering.

An ebullient nature lover’s paean to birds.
A charming bird journey with the bestselling author.
In his introduction to Tan’s “nature journal,” David Allen Sibley, the acclaimed ornithologist, nails the spirit of this book: a “collection of delightfully quirky, thoughtful, and personal observations of birds in sketches and words.” For years, Tan has looked out on her California backyard “paradise”—oaks, periwinkle vines, birch, Japanese maple, fuchsia shrubs—observing more than 60 species of birds, and she fashions her findings into delightful and approachable journal excerpts, accompanied by her gorgeous color sketches. As the entries—“a record of my life”—move along, the author becomes more adept at identifying and capturing them with words and pencils. Her first entry is September 16, 2017: Shortly after putting up hummingbird feeders, one of the tiny, delicate creatures landed on her hand and fed. “We have a relationship,” she writes. “I am in love.” By August 2018, her backyard “has become a menagerie of fledglings…all learning to fly.” Day by day, she has continued to learn more about the birds, their activities, and how she should relate to them; she also admits mistakes when they occur. In December 2018, she was excited to observe a Townsend’s Warbler—“Omigod! It’s looking at me. Displeased expression.” Battling pesky squirrels, Tan deployed Hot Pepper Suet to keep them away, and she deterred crows by hanging a fake one upside down. The author also declared war on outdoor cats when she learned they kill more than 1 billion birds per year. In May 2019, she notes that she spends $250 per month on beetle larvae. In June 2019, she confesses “spending more hours a day staring at birds than writing. How can I not?” Her last entry, on December 15, 2022, celebrates when an eating bird pauses, “looks and acknowledges I am there.”

SEEN & HEARD
A charming, thoughtful pleasure for any animal lover.
A celebration of animal companions, mammalian, reptilian, avian, and otherwise.
The Ulysses S. Cat of NPR commentator Simon’s title was a “chunky orange Scottish Fold with endearing floppy ears and a broad, flat face that looked…as if he had been running full steam after a mouse when a door opened and…splat!” He may not have been the most photogenic of critters, but he was a steadfast companion to Simon’s mother and stepfather as the latter suffered illness and death. Other creatures populate Simon’s pages: a betta named Salman Fishdie, a grasshopper named Hoppy, many dogs and cats. Simon ranges widely to collect his stories; among the most affecting is a portrait of the people of Sarajevo under siege by Serbian forces, punctuated by an impatient colleague’s saying to Simon, “I do not want to get shot while doing a fucking pet story.” A good point, that, but Simon is emboldened and moved by the Sarajevans’ and U.N. soldiers’ care for pets displaced from their homes. “In making room for animals at the lowest times of their lives,” he writes, “Sarajevo showed the world real humanitarian aid.” In a somewhat lighter turn, Simon voices the hope that the afterlife will involve meeting again with all the animals and people we have loved, with no hard distinction drawn between birds, dogs, cats, turtles, and other beloved animal companions and other members of one’s family, biological and elective. While recognizing that animals make us better humans, holding unconditional love but eschewing grudges, Simon also decries the misuse of animals, particularly in laboratory settings where other modeling methods can be used that do not visit pain and death on such creatures as chimpanzees and white rats. Writes Simon, meaningfully, “Someday, I’m pretty sure we’ll look back on our use of animals in this way as something brutal.” Amen.
