Gene Kranz was present at the creation of America's manned space program and was a key player in it for three decades. As a flight director in NASA's Mission Control, Kranz witnessed firsthand the making of history. He participated in the space program from the early days of the Mercury program to the last Apollo mission, and beyond. He endured the disastrous first years when rockets blew up and the United States seemed to fall further behind the Soviet Union in the space race.

Bob Lazar was a brilliant young physicist that found himself employed at a top-secret facility in the middle of the desert outside Las Vegas. Under the watchful eye of the government elite, he is tasked with understanding an exotic propulsion system being used by an advanced aerospace vehicle he is told came from outer space. The stressful work and long, odd hours start to wear on Bob and he becomes concerned for his safety. He tells his wife and a couple close friends about what he's doing in the desert, and his employers find out and are furious.

Drawing on 40 years of research and a treasure trove of new information, Tesla: Wizard at War provides a comprehensive view of Tesla's discoveries, which continue to influence today's military technology and diplomatic strategies. One of the world's leading Tesla experts, Marc J. Seifer, offers new insight into the brilliant scientist's particle beam weapon (aka the "Death Ray") and explores his military negotiations with pivotal historical figures - including his links to Joseph Stalin, Vannevar Bush, General Andrew McNaughton, and Franklin Delano Roosevelt.

I hate every wave of the ocean', the seasick Charles Darwin wrote to his family during his five-year voyage on the H.M.S. Beagle. It was this world-wide journey, however, that launched the scientists career.

Two of the boldest and most creative scientists of all time were Michael Faraday (1791-1867) and James Clerk Maxwell (1831-1879). This is the story of how these two men - separated in age by 40 years - discovered the existence of the electromagnetic field and devised a radically new theory which overturned the strictly mechanical view of the world that had prevailed since Newton's time.

An illuminating guide to the scientific and technological achievements of the Middle Ages through the life of a crusading astronomer-monk.

Step past the flashing lights into the true scene of the crime with this frank, unflinching, and unforgettable account of life as a crime scene investigator. Whether explaining rigor mortis or the art of fingerprinting a stiff corpse on the side of the road, Dana Kollmann details her true, unvarnished experiences as a CSI for the Baltimore County Police Department.

David L. Mearns has discovered some of the world's most fascinating and elusive shipwrecks. The Shipwreck Hunter chronicles his most intriguing finds. It describes the extraordinary techniques used, the detailed research, and mid-ocean stamina and courage required to find a wreck thousands of feet beneath the sea, plus the moving human stories that lie behind each of these oceanic tragedies. Combining the adventuring derring-do of Indiana Jones with the precision of a scientist, The Shipwreck Hunter opens an illuminating porthole into the shadowy depths of the ocean.

The founder of modern science and the embodiment of the conflict between science and faith, Galileo remains the most fascinating figure of his age. In this biography, James Reston Jr. provides a lively, vivid portrait of Galileo, taking the listener to the heart of this passionate, embattled, arrogant, and brilliant man.

What happens when something is sucked into a black hole? Does it disappear? Three decades ago, a young physicist named Stephen Hawking claimed that it did - and in doing so, put at risk everything we know about the fundamental laws of the universe. Leonard Susskind and Gerard 't Hooft realized the threat and responded with a counterattack that changed the course of physics.

Simply Electrifying: The Technology That Transformed the World, from Benjamin Franklin to Elon Musk brings to life the 250-year history of electricity through the stories of the men and women who used it to transform our world: Benjamin Franklin, James Watt, Michael Faraday, Samuel F.B. Morse, Thomas Edison, Samuel Insull, Albert Einstein, Rachel Carson, Elon Musk, and more. In the process, it reveals for the first time the complete, thrilling, and often dangerous story of electricity's historic discovery, development, and worldwide application.

In 1913, an unschooled young Indian clerk wrote a letter to G. H. Hardy, begging that preeminent English mathematician's opinion on several ideas he had about numbers. Hardy, realizing the letter was the work of a genius, arranged for Srinivasa Ramanujan to come to England. Thus began one of the most remarkable collaborations ever chronicled.

On February 1, 2003, Columbia disintegrated on reentry before the nation's eyes, and all seven astronauts aboard were lost. Author Mike Leinbach was a key leader in the search and recovery effort as NASA, FEMA, the FBI, the US Forest Service, and dozens more federal, state, and local agencies combed an area of rural east Texas the size of Rhode Island for every piece of the shuttle and her crew they could find. Assisted by hundreds of volunteers, it would become the largest ground search operation in US history.

Freeman Dyson is a world-renowned astrophysicist who dreams of exploring the heavens and has designed a spaceship to take him there. His son, George, a brilliant high-school dropout, lives in a tree house and is designing a giant kayak to explore the icy coastal wilderness of the Pacific Northwest and Alaska.

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.

In the 1970s, amid severe cutbacks in physics funding, a small group of underemployed physicists in Berkeley decided to throw off the constraints of academia and explore the wilder side of science. Dubbing themselves the “Fundamental Fysiks Group,” they pursued a freewheeling, speculative approach to physics. Some dabbled with LSD while conducting experiments. They studied quantum theory alongside Eastern mysticism and psychic mind reading, discussing the latest developments while lounging in hot tubs.

Frances Glessner Lee, born a socialite to a wealthy and influential Chicago family in the 1870s, was never meant to have a career, let alone one steeped in death and depravity. Yet she developed a fascination with the investigation of violent crimes and made it her life's work. Best known for creating the Nutshell Studies of Unexplained Death, a series of dollhouses that appear charming - until you notice the macabre little details: an overturned chair, or a blood-spattered comforter.

Two ambitious men. One historic mission. With a blinding flash in the New Mexico desert in the summer of 1945, the world was changed forever. The bomb that ushered in the atomic age was the product of one of history's most improbable partnerships. The General and the Genius reveals how two extraordinary men pulled off the greatest scientific feat of the 20th century.

Raymond Ditmars (1876-1942), the first curator of reptiles at New York's famous Bronx Zoo, brought cold-blooded animals to public attention as never before. Through wildly successful books and movies, he inspired a generation of zoologists with his fascination for snakes, insects, and other misunderstood creatures. Ditmars was among the most celebrated naturalists in America. His reptile-collecting trips for the zoo spawned newspaper headlines across the world.

Born in 1905 in the center of the crumbling Austro-Hungarian Empire, Viktor Frankl was a witness to the great political, philosophical, and scientific upheavals of the 20th century. In these stirring recollections, Frankl describes how as a young doctor of neurology in prewar Vienna, his disagreements with Freud and Adler led to the development of "the third Viennese School of Psychotherapy", known as logotherapy; recounts his harrowing trials in four concentration camps during the War; and reflects on the celebrity brought by Man's Search for Meaning in 1945.
