A tracing of the history of the concept of the Golden Mean from its prehistoric beginnings through its use by ancient Egyptians and its analysis by the early Greeks. The book chronicles the Golden Mean's use in the Middle Ages and its eventual abandonment after the advent of the Industrial Revolution.

A NEW YORK TIMES NOTABLE BOOK • The dramatic story of the Flint water crisis, by a relentless physician who stood up to power. “Stirring . . . [a] blueprint for all those who believe . . . that ‘the world . . . should be full of people raising their voices.’”—The New York Times “Revealing, with the gripping intrigue of a Grisham thriller.” —O: The Oprah Magazine Here is the inspiring story of how Dr. Mona Hanna-Attisha, alongside a team of researchers, parents, friends, and community leaders, discovered that the children of Flint, Michigan, were being exposed to lead in their tap water—and then battled her own government and a brutal backlash to expose that truth to the world. Paced like a scientific thriller, What the Eyes Don’t See reveals how misguided austerity policies, broken democracy, and callous bureaucratic indifference placed an entire city at risk. And at the center of the story is Dr. Mona herself—an immigrant, doctor, scientist, and mother whose family’s activist roots inspired her pursuit of justice. What the Eyes Don’t See is a riveting account of a shameful disaster that became a tale of hope, the story of a city on the ropes that came together to fight for justice, self-determination, and the right to build a better world for their—and all of our—children. Praise for What the Eyes Don’t See “It is one thing to point out a problem. It is another thing altogether to step up and work to fix it. Mona Hanna-Attisha is a true American hero.”—Erin Brockovich “A clarion call to live a life of purpose.”—The Washington Post “Gripping . . . entertaining . . . Her book has power precisely because she takes the events she recounts so personally. . . . Moral outrage present on every page.”—The New York Times Book Review “Personal and emotional. . . She vividly describes the effects of lead poisoning on her young patients. . . . She is at her best when recounting the detective work she undertook after a tip-off about lead levels from a friend. . . . ‛Flint will not be defined by this crisis,’ vows Ms. Hanna-Attisha.”—The Economist “Flint is a public health disaster. But it was Dr. Mona, this caring, tough pediatrican turned detective, who cracked the case.”—Rachel Maddow
