"Before John Glenn orbited the earth or Neil Armstrong walked on the moon, a group of dedicated female mathematicians known as "human computers" used pencils, slide rules and adding machines to calculate the numbers that would launch rockets, and astronauts, into space. Among these problem-solvers were a group of exceptionally talented African American women, some of the brightest minds of their generation. Originally relegated to teaching math in...

Edwards and Harris discuss the critical contributions black women made to NASA in the 1950s. They performed by hand the calculations that made it possible for the nation's astronauts to fly into space and return safely to Earth. Their efforts made it possible for young black women of subsequent generations to become the mathematicians and astrophysicists of today.--

"The riveting true story of the women who launched America into space. During World War II, when the newly minted Jet Propulsion Laboratory needed quick-thinking mathematicians to calculate jet velocities and plot missile trajectories, they recruited an elite group of young women--known as human computers--who, with only pencil, paper, and mathematical prowess, transformed rocket design and helped bring about America's first ballistic missiles. But...

Paul J. Nahin is the author of many bestselling popular math books, including Mrs. Perkins's Electric Quilt, In Praise of Simple Physics, and An Imaginary Tale (all Princeton). He is professor emeritus of electrical engineering at the University of New Hampshire. How two pioneers of math and technology ushered in the computer revolution Boolean algebra, also called Boolean logic, is at the heart of the electronic circuitry in everything we use-from...

"You've likely heard of the historic Apollo 13 [mission]. But do you know about the mathematical genius who made sure that Apollo 13 returned safely home? As a child, Katherine Johnson loved to count. She counted the steps on the road, the number of dishes and spoons she washed in the kitchen sink, everything! Boundless, curious, and excited by calculations, young Katherine longed to know as much as she could about math, about the universe. From Katherine's...

"For John Urschel, what began as an insatiable appetite for puzzles as a child quickly evolved into mastery of the elegant systems and rules of mathematics. By the time he was thirteen, Urschel was auditing college-level calculus courses. But when he joined his high school football team, a new interest began to eclipse the thrill he once felt in the classroom. Football challenged Urschel in an entirely different way, and he became addicted to the...

"The astonishing story of Dr. Josephine Janina Mehlberg--a Jewish mathematician who saved thousands of lives in Nazi-occupied Poland by masquerading as a Polish aristocrat--drawing on Mehlberg's own unpublished memoir. World War II and the Holocaust have given rise to many stories of resistance and rescue, but The Counterfeit Countess is unique. It tells the remarkable, unknown story of "Countess Janina Suchodolska," a Jewish woman who rescued more...
