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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

A 23-year veteran of emergency medical services, paramedic Matthew Sias took a detour in his career to pursue the death-care business and found a complementarity between two seemingly divergent careers. Silent Siren: Memoirs of a Life Saving Mortician is the record of some of the more memorable calls he has responded to through the years.

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.

From the acclaimed author of The Nobel Prize comes this fascinating portrait of four of the greatest minds in the history of science and the impossible turning point they faced. As World War II wound down, and it became increasingly clear that the Allies would emerge victorious, Albert Einstein invited three close friends - all titans of contemporary science and philosophy - to his home at 112 Mercer Street in Princeton, New Jersey, to discuss what they loved best: science and philosophy.

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.

In the late 1930s, legendary financier, philanthropist, and society figure Alfred Lee Loomis gathered the most visionary scientific minds of the 20th century at his state-of-the-art laboratory in Tuxedo Park, New York. He established a top-secret defense laboratory at MIT and personally bankrolled pioneering research into new, high-powered radar detection systems that helped defeat the German Air Force and U-boats. With Ernest Lawrence, he pushed Franklin Delano Roosevelt to fund research in nuclear fission, which led to the development of the atomic bomb.

Ninteen ninety-four, Northern California. The Internet is just emerging from its origins in the military and university research labs. Groups of idealistic technologists, recognizing its potential as a tool for liberation and solidarity, are working feverishly to build the network. In the early chat rooms of one such gathering, soon-to-become-famous as The WELL, a Stanford futurist named Tom Mandel creates a new conference. In a topic headed "Local Bug Report", he asks for advice from fellow online participants about how he might shake off a persistent hacking cough.

In 1949, Ron Losee, a young Yale Medical School graduate, headed west with his wife and small daughter to begin the practice of medicine. They settled in Ennis, Montana, in a log cabin that also became their office and lab. Patients made themselves at home in the living room. One small bag held all their medical equipment. It was a proud moment when a patient first called Losee "Doc." His fee on that occasion was three dollars.

A true scientific pause-resister that traces a remarkable scientific breakthrough (the isolation of endorphins in the brain) as dedicated scientists race - not only with their fellow scientists - but against time and the profit hungry giant pharmaceutical companies. This audiobook chronicles the fascinating discovery of endorphins, the body's natural painkiller.

A born naturalist and a fearless traveler, Vladimir Dinets wrote travel guides, conducted field research, and lived a couple of lives before he was accepted into the PhD program in zoology at the University of Miami. He thought crocodiles were a dead-end research topic - survivors from the age of the dinosaurs but not much else - until he witnessed groups of up to seventy alligators performing mating choruses that included infrasound vibrations - a form of communication extremely rare in nature.
