The remarkable woman at heart of the smash New York Times bestseller and Oscar-winning film Hidden Figures tells the full story of her life, including what it took to work at NASA, help land the first man on the moon, and live through a century of turmoil and change. In 2015, at the age of 97, Katherine Johnson became a global celebrity. President Barack Obama awarded her the prestigious Presidential Medal of Freedom—the nation’s highest civilian honor—for her pioneering work as a mathematician on NASA’s first flights into space. Her contributions to America’s space program were celebrated in a blockbuster and Academy-award nominated movie. In this memoir, Katherine shares her personal journey from child prodigy in the Allegheny Mountains of West Virginia to NASA human computer. In her life after retirement, she served as a beacon of light for her family and community alike. Her story is centered around the basic tenets of her life—no one is better than you, education is paramount, and asking questions can break barriers. The memoir captures the many facets of this unique woman: the curious “daddy’s girl,” pioneering professional, and sage elder. This multidimensional portrait is also the record of a century of racial history that reveals the influential role educators at segregated schools and Historically Black Colleges and Universities played in nurturing the dreams of trailblazers like Katherine. The author pays homage to her mentor—the African American professor who inspired her to become a research mathematician despite having his own dream crushed by racism. Infused with the uplifting wisdom of a woman who handled great fame with genuine humility and great tragedy with enduring hope, My Remarkable Journey ultimately brings into focus a determined woman who navigated tough racial terrain with soft-spoken grace—and the unrelenting grit required to make history and inspire future generations.

The irresistibly engaging book that "enlarges one's wonder at Tammet's mind and his all-embracing vision of the world as grounded in numbers" (Oliver Sacks, MD). Thinking in Numbers is the book that Daniel Tammet, mathematical savant and bestselling author, was born to write. In Tammet's world, numbers are beautiful and mathematics illuminates our lives and minds. Using anecdotes, everyday examples, and ruminations on history, literature, and more, Tammet allows us to share his unique insights and delight in the way numbers, fractions, and equations underpin all our lives. Inspired variously by the complexity of snowflakes, Anne Boleyn's eleven fingers, and his many siblings, Tammet explores questions such as why time seems to speed up as we age, whether there is such a thing as an average person, and how we can make sense of those we love. His provocative and inspiring new book will change the way you think about math and fire your imagination to view the world with fresh eyes.

In 1202, a 32-year old Italian finished one of the most influential books of all time, which introduced modern arithmetic to Western Europe. Devised in India in the seventh and eighth centuries and brought to North Africa by Muslim traders, the Hindu-Arabic system helped transform the West into the dominant force in science, technology, and commerce, leaving behind Muslim cultures which had long known it but had failed to see its potential. The young Italian, Leonardo of Pisa (better known today as Fibonacci), had learned the Hindu number system when he traveled to North Africa with his father, a customs agent. The book he created was Liber abbaci, the 'Book of Calculation', and the revolution that followed its publication was enormous. Arithmetic made it possible for ordinary people to buy and sell goods, convert currencies, and keep accurate records of possessions more readily than ever before. Liber abbaci's publication led directly to large-scale international commerce and the scientific revolution of the Renaissance. Yet despite the ubiquity of his discoveries, Leonardo of Pisa remains an enigma. His name is best known today in association with an exercise in Liber abbaci whose solution gives rise to a sequence of numbers - the Fibonacci sequence - used by some to predict the rise and fall of financial markets, and evident in myriad biological structures. In The Man of Numbers, Keith Devlin recreates the life and enduring legacy of an overlooked genius, and in the process makes clear how central numbers and mathematics are to our daily lives.

When William Beebe needed to know what was going on in the depths of the ocean, he had himself lowered a half-mile down in a four-foot steel sphere to see-five times deeper than anyone had ever gone in the 1930s. When he wanted to trace the evolution of pheasants in 1910, he trekked on foot through the mountains and jungles of the Far East to locate every species. To decipher the complex ecology of the tropics, he studied the interactions of every creature and plant in a small area from the top down, setting the emerging field of tropical ecology into dynamic motion. William Beebe's curiosity about the natural world was insatiable, and he did nothing by halves. As the first biographer to see the letters and private journals Beebe kept from 1887 until his death in 1962, science writer Carol Grant Gould brings the life and times of this groundbreaking scientist and explorer compellingly to light. From the Galapagos Islands to the jungles of British Guiana, from the Bronx Zoo to the deep seas, Beebe's biography is a riveting adventure. A best-selling author in his own time, Beebe was a fearless explorer and thoughtful scientist who put his life on the line in pursuit of knowledge. The unique glimpses he provided into the complex web of interactions that keeps the earth alive and breathing have inspired generations of conservationists and ecologists. This exciting biography of a great naturalist brings William Beebe at last to the recognition he deserves.

A frank account of the tempestuous life of the American mother of Britain’s most important twentieth-century politician. Brooklyn-born Jennie Jerome married into the British aristocracy in 1874, after a three-day romance. She became Lady Randolph Churchill, wife of a maverick politician and mother of the most famous British statesman of the century. Jennie Churchill was not merely the most talked about and controversial American woman in London society, she was a dynamic behind-the-scenes political force and a woman of sexual fearlessness at a time when women were not supposed to be sexually liberated. A concert pianist, magazine founder and editor, and playwright, she was also, above all, a devoted mother to Winston. In American Jennie, Anne Sebba draws on newly discovered personal correspondences and archives to examine the unusually powerful mutual infatuation between Jennie and her son and to relate the passionate and ultimately tragic career of the woman whom Winston described as having “the wine of life in her veins.”

This biography highlights the achievements of America's first professional degreed female scientist, Ellen Swallow Richards (1842--1911). The book takes the reader from Richards's childhood on a Massachusetts farm where she was schooled at home, to her internationally renowned successes in multiple branches of science. • Schools, colleges, and libraries are searching for more books about remarkable, successful women. Richards paved the way for women to enter numerous fields of science previously believed to be the domain of men. • Currently there is much emphasis on nutrition; Richards pioneered in this field, teaching the American public about fats, carbohydrates, proteins and calories at a time when scarcely anyone knew of their importance. • Ellen Swallow Richards pioneered multiple fields of science and technology, opening doors for women to become chemists, biologists, geologists, ecologists, nutritionists, dietitians, science teachers, professors, and home economists. • Richards began the ecology movement, particularly relevant in today's world as more and more attention is being paid to the health of our planet.

This “seriously entertaining book” explores the skin in its multifaceted physical, psychological, and social aspects (Times, UK). Providing a cover for our delicate bodies, the skin is our largest and fastest-growing organ. We see it, touch it, and live in it every day. It is a habitat for a mesmerizingly complex world of micro-organisms and physical functions that are vital to our health and survival. One of the first things people see about us, skin is also crucial to our sense of identity. And yet much about it is largely unknown to us. With rigorous research and lucid prose, Monty Lyman explores our outer surface through the lenses of science, sociology, and history. He covers topics as diverse as the mechanics and magic of touch (how much goes on in the simple act of taking keys out of a pocket and unlocking a door is astounding), the close connection between the skin and the gut, what happens instantly when one gets a paper cut, and how a midnight snack can lead to sunburn. The Remarkable Life of the Skin takes readers on a journey across our most underrated and unexplored organ. It reveals how our skin is far stranger, more wondrous, and more complex than we have ever imagined.
