In Native American DNA, Kim TallBear shows how DNA testing is a powerful - and problematic - scientific process that is useful in determining close biological relatives. But tribal membership is a legal category that has developed in dependence on certain social understandings and historical contexts, a set of concepts that entangles genetic information in a web of family relations, reservation histories, tribal rules, and government regulations.

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.

Early True Believers: The Untold Story of Silicon Alley is a 1990s saga of ambition and innovation set in Manhattan’s Silicon Alley, a swath of downtown that served as New York City’s nerve center of tech entrepreneurship.

In this engaging audiobook, award-winning American history professor Tore Olsson takes up that question and more.

Ben Franklin's own lively story of his early years is a unique, fascinating, and influential look at this American founding father. It has been taught in schools as a moral tract, as a guide to self-improvement, and as the Great American Success Story. It also is relished both for its insight into colonial life and the mind of the man who most affected the development of our democratic form of government.

In this colorful and intimate narrative, Isaacson provides the full sweep of Franklin's amazing life, from his days as a runaway printer to his triumphs as a statesman, scientist, and Founding Father. He chronicles Franklin's tumultuous relationship with his illegitimate son and grandson, his practical marriage, and his flirtations with the ladies of Paris. He also shows how Franklin helped to create the American character and why he has a particular resonance in the twenty-first century.

Two-time winner of the Pulitzer Prize David McCullough tells the dramatic story behind the story about the courageous brothers who taught the world how to fly: Wilbur and Orville Wright.

On December 17, 1903, at Kitty Hawk, North Carolina, Wilbur and Orville Wright's Wright Flyer became the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot aboard. The Age of Flight had begun. How did they do it? And why?

More than 50 years ago, John Coltrane drew the 12 musical notes in a circle and connected them with straight lines, forming a five-pointed star. Inspired by Einstein, Coltrane had put physics and geometry at the core of his music. Physicist and jazz musician Stephon Alexander returns the favor, using jazz to answer physics' most vexing questions about the past and future of the universe.

A self-professed "comprehensive anticipatory design scientist", the inventor Buckminster Fuller (1895-1983) was undoubtedly a visionary. Fuller's creations often bordered on the realm of science fiction, ranging from the freestanding geodesic dome to the three-wheel Dymaxion car to a bathroom requiring neither plumbing nor sewage. Yet in spite of his brilliant mind and lifelong devotion to serving mankind, Fuller's expansive ideas were often dismissed, and have faded from public memory since his death.

The worst hard-rock mining disaster in American history began a half hour before midnight on June 8, 1917, when fire broke out in the North Butte Mining Company's Granite Mountain shaft. Sparked more than 2,000 feet below ground, the fire spewed flames, smoke, and poisonous gas through a labyrinth of underground tunnels. Within an hour more than 400 men would be locked in a battle to survive. Within three days 164 of them would be dead.

Mathematics shapes almost everything we do. But despite its reputation as the study of fundamental truths, the stories we have been told about it are wrong—warped like the sixteenth-century map that enlarged Europe at the expense of Africa, Asia and the Americas. In The Secret Lives of Numbers, renowned math historian Kate Kitagawa and journalist Timothy Revell make the case that the history of math is infinitely deeper, broader, and richer than the narrative we think we know.

When Thomas Edison was a boy, he loved performing experiments and coming up with new inventions.
