NUMBERS DON'T LIE

71 STORIES TO HELP US UNDERSTAND THE MODERN WORLD

A fascinating book to be read straight through or consulted bit by bit.

An assembly of short, numbers-based investigations into important questions of the day.

“My goal is to demonstrate not only that numbers do not lie, but to discover which truth they convey,” writes Smil of this tidy, entertaining collection of brief inquiries into a host of hot-button topics: vaccinations, the malleability of unemployment figures, the consequences of diesel fuel, the fossil fuels behind wind turbines, the environmental impact of cars and cellphones, and the realities of Brexit. Regarding the last, the author writes that the U.K. has become “another has-been power whose claim to uniqueness rests on having too many troubled princes and on exporting costumed TV series set in fading country mansions staffed with too many servants.” Some of the more lighthearted material—e.g., the surprising number of benefits that tall people enjoy—help take the sting out of the more formidable issues: why replacing kerosene with biofuels to power our airplanes would require the planting of 125 million hectares with soybeans; the ubiquity of synthetic fertilizer, without which more than 3 billion people could go hungry; the glacially slow pace of alternative energy. Though all of Smil’s subjects—from the “zoomass” of cows to the physics of triple-paned windows to the manual labor required to build the pyramids—are situated firmly within the realms of math and science, with plenty of kilonewtons and exajoules, the author also slips in cogent discussions of other relevant current-affairs topics, including the flawed yet enduring concept of American exceptionalism: “Politicians may look far and wide for evidence of [it], but they won’t find it in the numbers, where it matters.” Throughout, Smil’s viewpoint is balanced, and each element of the text is fully backed by research as well as the author’s contagious curiosity. Even when examining dire circumstances, Smil keeps readers engaged.

Words that made a nation.

Isaacson is known for expansive biographies of great thinkers (and Elon Musk), but here he pens a succinct, stimulating commentary on the Founding Fathers’ ode to “life, liberty, and the pursuit of happiness.” His close reading of the Declaration of Independence’s second sentence, published to mark the 250th anniversary of the document’s adoption, doesn’t downplay its “moral contradiction.” Thomas Jefferson enslaved hundreds of people yet called slavery “a cruel war against human nature” in his first draft of the Declaration. All but 15 of the document’s 56 signers owned enslaved people. While the sentence in question asserted “all men are created equal” and possess “unalienable rights,” the Founders “consciously and intentionally” excluded women, Native Americans, and enslaved people. And yet the sentence is powerful, Isaacson writes, because it names a young nation’s “aspirations.” He mounts a solid defense of what ought to be shared goals, among them economic fairness, “moral compassion,” and a willingness to compromise. “Democracy depends on this,” he writes. Isaacson is excellent when explaining how Enlightenment intellectuals abroad influenced the founders. Benjamin Franklin, one of the Declaration’s “five-person drafting committee,” stayed in David Hume’s home for a month in the early 1770s, “discussing ideas of natural rights” with the Scottish philosopher. Also strong is Isaacson’s discussion of the “edits and tweaks” made to Jefferson’s draft. As recommended by Franklin and others, the changes were substantial, leaving Jefferson “distraught.” Franklin, who emerges as the book’s hero, helped establish municipal services, founded a library, and encouraged religious diversity—the kind of civic-mindedness that we could use more of today, Isaacson reminds us.

A short, smart analysis of perhaps the most famous passage in American history reveals its potency and unfulfilled promise.

A neurosurgeon with a passion for literature tragically finds his perfect subject after his diagnosis of terminal lung cancer.

Writing isn’t brain surgery, but it’s rare when someone adept at the latter is also so accomplished at the former. Searching for meaning and purpose in his life, Kalanithi pursued a doctorate in literature and had felt certain that he wouldn’t enter the field of medicine, in which his father and other members of his family excelled. “But I couldn’t let go of the question,” he writes, after realizing that his goals “didn’t quite fit in an English department.” “Where did biology, morality, literature and philosophy intersect?” So he decided to set aside his doctoral dissertation and belatedly prepare for medical school, which “would allow me a chance to find answers that are not in books, to find a different sort of sublime, to forge relationships with the suffering, and to keep following the question of what makes human life meaningful, even in the face of death and decay.” The author’s empathy undoubtedly made him an exceptional doctor, and the precision of his prose—as well as the moral purpose underscoring it—suggests that he could have written a good book on any subject he chose. Part of what makes this book so essential is the fact that it was written under a death sentence following the diagnosis that upended his life, just as he was preparing to end his residency and attract offers at the top of his profession. Kalanithi learned he might have 10 years to live or perhaps five. Should he return to neurosurgery (he could and did), or should he write (he also did)? Should he and his wife have a baby? They did, eight months before he died, which was less than two years after the original diagnosis. “The fact of death is unsettling,” he understates. “Yet there is no other way to live.”

A moving meditation on mortality by a gifted writer whose dual perspectives of physician and patient provide a singular clarity.
