In such a scenario, it makes sense to focus on the most identifiable and urgent problems, right? Actually, it doesn't. In his classic essay "The Usefulness of Useless Knowledge," Abraham Flexner, the founding director of the Institute for Advanced Study in Princeton and the man who helped bring Albert Einstein to the United States, describes a great paradox of scientific research. The search for answers to deep questions, motivated solely by curiosity and without concern for applications, often leads not only to the greatest scientific discoveries but also to the most revolutionary technological breakthroughs. In short, no quantum mechanics, no computer chips.This brief book includes Flexner's timeless 1939 essay alongside a new companion essay by Robbert Dijkgraaf, the Institute's current director, in which he shows that Flexner's defense of the value of "the unobstructed pursuit of useless knowledge" may be even more relevant today than it was in the early twentieth century. Dijkgraaf describes how basic research has led to major transformations in the past century and explains why it is an essential precondition of innovation and the first step in social and cultural change. He makes the case that society can achieve deeper understanding and practical progress today and tomorrow only by truly valuing and substantially funding the curiosity-driven "pursuit of useless knowledge" in both the sciences and the humanities.

    Health inspectors called the neighborhood “the suicide ward.” Diarrhea epidemics raged each summer, killing thousands of children. Sweatshop babies with smallpox and typhus dozed in garment heaps destined for fashionable shops. Desperate mothers paced the streets to soothe their feverish children and white mourning cloths hung from every building. A third of the children living there died before their fifth birthday.By 1911, the child death rate had fallen sharply and The New York Times hailed the city as the healthiest on earth. In this witty and highly personal autobiography, public health crusader Dr. S. Josephine Baker explains how this transformation was achieved. By the time she retired in 1923, Baker was famous worldwide for saving the lives of 90,000 children. The programs she developed, many still in use today, have saved the lives of millions more. She fought for women’s suffrage, toured Russia in the 1930s, and captured “Typhoid” Mary Mallon, twice. She was also an astute observer of her times, and Fighting for Life is one of the most honest, compassionate memoirs of American medicine ever written.
