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.

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.

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.

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.

Gabriella Greison racconta la bizzarra esistenza e le ancor più straordinarie intuizioni di uno dei padri della fisica quantistica, Paul Dirac, fisico premio Nobel 1933. Dirac è stato un fisico geniale e un uomo strambo e meticoloso, costantemente impegnato a elaborare formule, fra cui quella meraviglia grazie alla quale è entrato nella storia della scienza e che lo indica sulla lapide nell'Abbazia di Westminster a fianco di Isaac Newton: i? + ?? = m?.

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.

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.

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 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.

In the 1950s, Anne Innis Dagg was a young zoologist with a lifelong love of the giraffe and a dream to study them in Africa. Based on extensive journals and letters home, Pursuing Giraffe vividly chronicles the realization of that dream and the year that she spent studying and documenting giraffe behaviour.

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.

In the gripping Never Panic Early, Fred Haise, Lunar Module Pilot for Apollo 13, offers a detailed firsthand account of when disaster struck three days into his mission to the moon. An oxygen tank exploded, a crewmate uttered the now iconic words, “Houston, we’ve had a problem here,” and the world anxiously watched as one of history’s most incredible rescue missions unfolded. Haise brings listeners into the heart of his experience on the challenging mission—considered NASA’s finest hour—and reflects on his life and career as an Apollo astronaut.

February 1, 2003. A light flashed over a Texas sky and twisted metal rained across the countryside. As images of the wreckage from the Space Shuttle Columbia streamed across the nation's television screens, they became forever burned into our memories. But behind those images were stories that remained untold...until now.

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.

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.

Aufgrund seiner bahnbrechenden Errungenschaften auf dem Gebiet der Physik wird Albert Einstein (1879-1955) der bekannteste Forscher des 20. Jahrhunderts - und zum Inbegriff des Wissenschaftlers, Genies und Pazifisten. Der erfahrene Autor und Herausgeber Bert Alexander Petzold nimmt uns mit auf eine faktenreiche Kulturreise und erläutert verständlich, unterhaltsam und strukturiert Basiswissen. Albert Einstein verändert mit seiner im Jahre 1905 veröffentlichten "Speziellen Relativitätstheorie" grundlegend das bis dahin geltende newtonsche Weltbild.

Sound interesting? The author thinks so too! Listen to Bharat 2020 and learn about A.P.J. Abdul Kalam's plan for how India can be included in the most powerful and prosperous five nations of the world in the next 20 years.

Nikola Tesla (1856-1943) è stato un profeta dell'era elettronica. La sua ricerca ha posto gran parte delle basi per i moderni sistemi elettrici e di comunicazione, e le sue impressionanti realizzazioni includono lo sviluppo del sistema elettrico a corrente alternata, la radio, il trasformatore a bobina di Tesla, la trasmissione senza fili e l'illuminazione fluorescente. La ricerca di Tesla era così innovativa che molti dei suoi contemporanei non sono riusciti a capirla, e altri scienziati sono ingiustamente accreditati per le sue innovazioni.
