By August 1968, the American space program was in danger of failing in its two most important objectives: to land a man on the moon by President Kennedy's end-of-decade deadline and to triumph over the Soviets in space. With its back against the wall, NASA made an almost unimaginable leap: It would scrap its usual methodical approach and risk everything on a sudden launch, sending the first men in history to the moon - in just four months.

In 1714, England's Parliament offered a huge reward to anyone whose method of measuring longitude could be proven successful. The scientific establishment--from Galileo to Sir Isaac Newton--had mapped the heavens in its certainty of a celestial answer. In stark contrast, one man, John Harrison, dared to imagine a mechanical solution--a clock that would keep precise time at sea, something no clock had been able to do on land. And the race was on....

In the 1940s and '50s, when the newly minted Jet Propulsion Laboratory needed quick-thinking mathematicians to calculate velocities and plot trajectories, they didn't turn to male graduates. Rather, they recruited an elite group of young women who, with only pencil, paper, and mathematical prowess, transformed rocket design, helped bring about the first American satellites, and made the exploration of the solar system possible.

In The Optimist, the Wall Street Journal reporter Keach Hagey presents the most detailed account yet of Altman’s rise, from his precocious childhood in St. Louis to his first, failed startup experience; his time as legendary entrepreneur Paul Graham’s protégé and successor as head of Y Combinator, the start-up accelerator where Altman became the premier power broker in Silicon Valley; the founding of OpenAI and his recruitment of a small yet superior team; and his struggle to keep his company at the cutting edge while fending off determined rivals, including Elon Musk.

In the 18th century, two men dedicated their lives to the same daunting task: identifying and describing all life on Earth. Their approaches could not have been more different. Carl Linnaeus, a pious Swedish doctor with a huckster's flair, believed that life belonged in tidy, static categories. Georges-Louis de Buffon, an aristocratic polymath and keeper of France's royal garden, viewed life as a dynamic swirl of complexities. Both began believing their work to be difficult, but not impossible—how could the planet possibly hold more than a few thousand species?

The bestselling author of Leonardo da Vinci and Steve Jobs returns with a “compelling” (The Washington Post) account of how Nobel Prize winner Jennifer Doudna and her colleagues launched a revolution that will allow us to cure diseases, fend off viruses, and have healthier babies.

Wired called Dr. Fei-Fei Li “one of a tiny group of scientists—a group perhaps small enough to fit around a kitchen table—who are responsible for AI’s recent remarkable advances.” Known to the world as the creator of ImageNet, a key catalyst of modern artificial intelligence, Dr. Li has spent more than two decades at the forefront of the field. But her career in science was improbable from the start. The Worlds I See is the moving memoir of a scientist coming of age as an immigrant in America who finds her calling at the forefront of the AI revolution.

Clarence L. "Kelly" Johnson led the design of such crucial aircraft as the P-38 and Constellation, but he will be more remembered for the U-2 and SR-71 spy planes. His extraordinary leadership of the Lockheed "Skunk Works" cemented his reputation as a legendary figure in American aerospace management.

Her name was Henrietta Lacks, but scientists know her as HeLa. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells - taken without her knowledge - became one of the most important tools in medicine: The first “immortal” human cells grown in culture, which are still alive today, though she has been dead for more than 60 years. HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects.

In Carrying the Fire, Michael Collins conveys, in a very personal way, the drama, beauty, and humor of the adventure of reaching the moon. He also traces his development from his first flight experiences in the air force, through his days as a test pilot, to his Apollo 11 spacewalk, presenting an evocative description of the joys of flight as well as a new perspective on time, light, and movement from someone who has seen the fragile Earth from the other side of the moon.

Kristine Barnett’s son Jacob has an IQ higher than Einstein’s, a photographic memory, and he taught himself calculus in two weeks. At 9 he started working on an original theory in astrophysics that experts believe may someday put him in line for a Nobel Prize, and at age 12 he became a paid researcher in quantum physics. But the story of Kristine’s journey with Jake is all the more remarkable because his extraordinary mind was almost lost to autism. At age 2, when Jake was diagnosed, Kristine was told he might never be able to tie his own shoes.

Through clear-eyed essays and vibrant conversations, infused with data and poetry, Ayana Elizabeth Johnson guides us through solutions and possibilities at the nexus of science, policy, culture, and justice. Visionary farmers and financiers, architects and advocates, help us conjure a flourishing future, one worth the effort it will take—from every one of us, with whatever we have to offer—to create.

In the 1930s, Germany was a hotbed of scientific thought. But after the Nazis took power, Jewish and female citizens were forced out of their academic positions. Hedwig Kohn, Lise Meitner, Hertha Sponer and Hildegard Stücklen were eminent in their fields, but they had no choice but to flee due to their Jewish ancestry or anti-Nazi sentiments. Their harrowing journey out of Germany became a life-and-death situation that required Herculean efforts of friends and other prominent scientists.

From the author of the national best seller Chaos comes an outstanding biography of one of the most dazzling and flamboyant scientists of the 20th century that "not only paints a highly attractive portrait of Feynman but also . . . makes for a stimulating adventure in the annals of science." ( The New York Times).

In this scientifically informed account of the changes occurring in the world over the last century, award-winning broadcaster and natural historian Sir David Attenborough shares a lifetime of wisdom and a hopeful vision for the future.

On October 5th, 1984, Marc Garneau made history. Blasting off from the Kennedy Space Center aboard the U.S. Space Shuttle and reaching a speed of 28,000 km/hour, he became the first Canadian to fly to outer space. That monumental achievement, now etched in Canadian history as one of our country’s proudest moments, inspired a nation and ushered in a new era of space exploration for Canada. Twenty-four years later, Garneau made history yet again, becoming the first astronaut to be elected as a Member of Parliament.
