The name of Charles Darwin is known to nearly all who have had the benefit of a Western-style education. It is synonymous with the theory of evolution and due to his perspective of man as an animal, his worked ushered in a new paradigm of understanding of the physical and mental behavior of man. However, because of the immense impact of his best known theory, most know only of his work through reviews and historical reports.

Without John C. Houbolt, a mid-level engineer at NASA, Apollo 11 would never have made it to the moon. Top NASA engineers on the project, including Werner Von Braun, strongly advocated for a single, huge spacecraft to travel to the moon, land, and return to Earth. It's the scenario used in 1950s cartoons and horror movies about traveling to outer space. Houbolt had another idea: Lunar Orbit Rendezvous. LOR would link two spacecraft in orbit while the crafts were travelling at 3,600 miles an hour around the moon. His plan was ridiculed and considered unthinkable.

By his early thirties, Paul Allen was a world-famous billionaire-and that was just the beginning. In 2007 and 2008, Time named Paul Allen, the cofounder of Microsoft, one of the hundred most influential people in the world. Since he made his fortune, his impact has been felt in science...

The saga of the greatest tornado chaser who ever lived: a tale of obsession and daring and an extraordinary account of humanity’s high-stakes race to understand nature’s fiercest phenomenon from Brantley Hargrove, “one of today’s great science writers” (The Washington Post). At the...

A preeminent geneticist hunts the Neanderthal genome to answer the biggest question of them all: what does it mean to be human? What can we learn from the genes of our closest evolutionary relatives? Neanderthal Man tells the story of geneticist Svante Pbo’s mission to answer that question, beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in his sequencing of the Neanderthal genome in 2009.

Now a major motion picture, this is the first—and only—definitive authorized account of Neil Armstrong, the man whose “one small step” changed history. When Apollo 11 touched down on the Moon’s surface in 1969, the first man on the Moon became a legend. In First Man, author James R...

As Marc Raboy shows us in this enthralling and comprehensive biography, Marconi was the first truly global figure in modern communications. Born to an Italian father and an Irish mother, he was in many ways stateless, working his cosmopolitanism to advantage. Through a combination of skill, tenacity, luck, vision, and timing, Marconi popularized - and, more critically, patented - the use of radio waves.

Edwin Grosvenor writes of Bell's other extraordinary inventions: the first transmission of sound over light waves, metal detector, first practical phonograph, and early airplanes, including the first to fly in Canada. He also examines Bell's humanitarian efforts, including support for women's suffrage, civil rights, and speeches about what he warned would be a "greenhouse effect" of pollution causing global warming.

The Man Who Mastered Gravity is an intimate profile of Thomas Townsend Brown, a little-known scientist whose unorthodox ideas about electricity and gravity have made him the subject of decades of speculation and intrigue. Brown developed his novel concepts while serving in the U.S. Navy through the 1930s. In the first months of World War II he was abruptly discharged–despite his expertise in radio, radar, and mine sweeping.

Revealed for the first time in Racing for the Bomb, Groves played a crucial and decisive role in the planning, timing, and targeting of the Hiroshima and Nagasaki missions. Norris offers new insights into the complex and controversial questions surrounding the decision to drop the bomb in Japan and Groves' actions during World War II, which had a lasting imprint on the nuclear age and the Cold War that followed.

“Gripping…an outstanding portrait” (The Wall Street Journal) of one of the most influential men of the greatest generation, James B. Conant—a savvy architect of the nuclear age and the Cold War—told by his granddaughter, New York Times bestselling author Jennet Conant. James Bryant...

Steve Jobs didn’t invent the future. He made it feel inevitable. From a California garage to global godhood, this is the story of the man who turned computers into companions, products into rituals, and simplicity into a cult. But beneath the keynote charisma and polished glass lies something deeper: obsession, control, intuition, rage, and raw design philosophy that reshaped the modern world. Jobs: The Man Behind the Glass goes beyond the black turtleneck myth to uncover the ghost still flickering inside every screen. Because what he built wasn’t just a company.

Before there was Steve Jobs, there was Norman Bel Geddes. A ninth-grade dropout who found himself at the center of the worlds of industry, advertising, theater, and even gaming, Bel Geddes designed everything from the first all-weather stadium to Manhattan's most exclusive nightclub to Futurama, the prescient 1939 exhibit that envisioned how America would look in the not-too-distant 1960s.

To solve one of the great mathematical problems of his day, Alan Turing proposed an imaginary computer. Then, attempting to break a Nazi code during World War II, he successfully designed and built one, thus ensuring the Allied victory. Turing became a champion of artificial intelligence, but his work was cut short. As an openly gay man at a time when homosexuality was illegal in England, he was convicted and forced to undergo a humiliating "treatment" that may have led to his suicide.

Against the backdrop of the late Cold War, a tiny American start-up company forged a secret deal to place American scientific payloads aboard the Soviet space station MIR. Born out of sheer desperation after the Challenger explosion and grounding of the United States space shuttle program, the agreement was negotiated and approved behind the backs of NASA and Congress, with the help of United States government officials inside the Commerce and Defense departments.

Today most people remember Leonardo for his few surviving anatomically correct works of art. They forget that Leonardo spent most of his life experimenting and designing automated machines. He constantly observed the mechanics of nature. He dissected human bodies, carefully recording the workings of muscles and organs. He studied optics, sound and light, gravity, heliocentric celestial mechanics, physical geology, fluid dynamics, and especially the flight of birds.

Why don’t we know the name of John Atanasoff as well as we know those of Alan Turing and John von Neumann? Because he never patented his computing machine, and because the developers of the far-better-known ENIAC almost certainly stole critical ideas from him. Jane Smiley tells the quintessentially American story of John Atanasoff with technical clarity and narrative drive, making the race to develop digital computing as gripping as a real-life techno-thriller.

The definitive biography of the brilliant, charismatic, and very human physicist and innovator Enrico Fermi In 1942, a team at the University of Chicago achieved what no one had before: a nuclear chain reaction. At the forefront of this breakthrough stood Enrico Fermi. Straddling the ages of...

As a young boy Frank Kovac Jr. fell deeply in love with stargazing, painting glow-in-the-dark constellations on his bedroom wall and inviting friends to an observatory he built in his Chicago backyard. As he reached adulthood, Kovac did not let go of his childhood dreams of reaching the stars. He began scheming to bring the universe home. While working at a paper mill as a young man, Kovac tirelessly built a 22-foot rotating globe planetarium in the woods.
