MATH WITHOUT NUMBERS

A math prodigy examines how mathematicians view the world.

Math enthusiasts have a spotty record explaining their favorite subject to a popular audience, even when they exert themselves to hold attention with calculating tricks, paradoxes, or illusions. Beckman, who entered Harvard at age 15, eschews them all, maintaining that everything—“plants, love, music, everything”—can be understood in terms of math and proceeds to explain how mathematicians try. They love to overthink things. “We take some concept everyone understands on a basic level, like symmetry or equality, and pick it apart, trying to find a deeper meaning in it.” His first example is a simple concept: shape. By the mathematical definition, a square and a circle have the same shape, but a figure 8 is different. It turns out that thinking about shapes is a major field of study called topology. Beckman admits that this has no practical significance, but it’s odd and interesting, and most readers will agree. There seems little to say about infinity, but this turns out to be wrong and pleasantly bizarre. If you remove any number of marbles from a bag containing infinite marbles, what’s left is still infinite. Adding one or 1 trillion—still exactly infinite. Infinity times infinity…the same. Is any quantity more than infinity? Yes; it’s called the continuum, and Beckman offers a fairly clear explanation. Ultimately, the author argues that math is not about numbers or equations but models. A model breaks down phenomena into specific rules that, when applied, explain it. A few simple rules produce a quasi-game remarkably similar to Darwinian natural selection. Beckman concludes with a model of an empty space containing 17 particles that follow well-defined if absurd rules, but the end result is the “standard model,” physicists’ best interpretation of how the universe operates.

An oft-ignored but fully convincing argument that “we cannot prevent the next pandemic without creating a healthy world.”

THE CONTAGION NEXT TIME

The Covid-19 pandemic is not a one-off catastrophe. An epidemiologist presents a cogent argument for a fundamental refocusing of resources on “the foundational forces that shape health.”

In this passionate and instructive book, Galea, dean of the Boston University School of Public Health, writes that Covid emerged because we have long neglected basic preventative measures. “We invest vast amounts of money in healthcare,” he writes, “but comparatively little in health.” Readers looking to learn how governments (mainly the U.S.) mishandled the pandemic have a flood of books to choose from, but Galea has bigger issues to raise. Better medical care will not stop the next epidemic, he warns. We must structure a world “that is resilient to contagions.” He begins by describing the current state of world health, where progress has been spectacular. Global life expectancy has more than doubled since 1900. Malnutrition, poverty, and child mortality have dropped. However, as the author stresses repeatedly, medical progress contributed far less to the current situation than better food, clean water, hygiene, education, and prosperity. That’s the good news. More problematic is that money is a powerful determinant of health; those who have it live longer. Galea begins the bad news by pointing out the misleading statistic that Covid-19 kills less than 1% of those infected; that applies to young people in good health. For those over 60, it kills 6%, for diabetics, over 7%, and those with heart disease, over 10%. It also kills more Blacks than Whites, more poor than middle-class people, and more people without health insurance. The author is clearly not just interested in Covid. He attacks racism, sexism, and poverty in equal measure, making a plea for compassion toward stigmatized conditions such as obesity and addiction. He consistently urges the U.S. government, which has spared no expense and effort to defeat the pandemic, to do the same for social injustice.

An oft-ignored but fully convincing argument that “we cannot prevent the next pandemic without creating a healthy world.”

THIS IS YOUR MIND ON PLANTS

Building on his lysergically drenched book How to Change Your Mind (2018), Pollan looks at three plant-based drugs and the mental effects they can produce.

The disastrous war on drugs began under Nixon to control two classes of perceived enemies: anti-war protestors and Black citizens. That cynical effort, writes the author, drives home the point that “societies condone the mind-changing drugs that help uphold society’s rule and ban the ones that are seen to undermine it.” One such drug is opium, for which Pollan daringly offers a recipe for home gardeners to make a tea laced with the stuff, producing “a radical and by no means unpleasant sense of passivity.” You can’t overthrow a government when so chilled out, and the real crisis is the manufacture of synthetic opioids, which the author roundly condemns. Pollan delivers a compelling backstory: This section dates to 1997, but he had to leave portions out of the original publication to keep the Drug Enforcement Administration from his door. Caffeine is legal, but it has stronger effects than opium, as the author learned when he tried to quit: “I came to see how integral caffeine is to the daily work of knitting ourselves back together after the fraying of consciousness during sleep.” Still, back in the day, the introduction of caffeine to the marketplace tempered the massive amounts of alcohol people were drinking even though a cup of coffee at noon will keep banging on your brain at midnight. As for the cactus species that “is busy transforming sunlight into mescaline right in my front yard”? Anyone can grow it, it seems, but not everyone will enjoy effects that, in one Pollan experiment, “felt like a kind of madness.” To his credit, the author also wrestles with issues of cultural appropriation, since in some places it’s now easier for a suburbanite to grow San Pedro cacti than for a Native American to use it ceremonially.

A lucid (in the sky with diamonds) look at the hows, whys, and occasional demerits of altering one’s mind.
