Asked to name a great physicist, most people would mention Newton or Einstein, Feynman or Hawking. But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list. Maxwell, an unassuming Victorian Scotsman, explained how we perceive color. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.

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.

In 1919, British scientists led extraordinary expeditions to Brazil and Africa to test Albert Einstein's revolutionary new theory of general relativity in what became the century's most celebrated scientific experiment. The result ushered in a new era and made Einstein a global celebrity by confirming his dramatic prediction that the path of light rays would be bent by gravity. Today, Einstein's theory is scientific fact. Yet the effort to "weigh light" by measuring the gravitational deflection of starlight during the May 29, 1919, solar eclipse has been clouded by myth and skepticism.

David Attenborough first appeared in front of a television camera in the 1950s when, together with London Zoo's Curator of Reptiles, Jack Lester, he persuaded the BBC to mount and film an animal-collecting expedition. The result was Zoo Quest. Specially recorded for audio, David Attenborough's early adventures are sometimes life-threatening, often hilarious and always totally absorbing. The warmth and enthusiasm that have made him a broadcasting legend are instantly apparent here as he recounts this magical journey.

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.

Every physicist agrees quantum mechanics is among humanity's finest scientific achievements. But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's solipsistic and poorly reasoned Copenhagen interpretation. Indeed, questioning it has long meant professional ruin, yet some daring physicists, such as John Bell, David Bohm, and Hugh Everett, persisted in seeking the true meaning of quantum mechanics. What Is Real? is the gripping story of this battle of ideas and the courageous scientists who dared to stand up for truth.

On July 22, 2009, a special meeting was held with 24 leading scientists at the National Institutes of Health to discuss early findings that a newly discovered retrovirus was linked to chronic fatigue syndrome (CFS), prostate cancer, lymphoma, and eventually neurodevelopmental disorders in children. When Dr. Judy Mikovits finished her presentation the room was silent for a moment, then one of the scientists said, "Oh my God!" The resulting investigation would be like no other in science.

Nixon declared the war on cancer in 1971. Forty-five years and billions of dollars later, it looks like we have lost the battle. Or have we? When a natural, non-toxic way to fight cancer is discovered, it is big news in the scientific community. But instead of being embraced, it is fiercely opposed by those tied to the pharmaceutical industry. Research by the late Mirko Beljanski, PhD, - one of the first green molecular biologists - revealed that natural molecules can selectively target cancer cells and work alongside many chemotherapy drugs.

The controversial Emanuel Revici, M.D., made the bones grow back in cancer patients, and restored health to AIDS patients as well as drug addicts and alcoholics. His medicines lifted debilitating migraines in as little as three minutes. Revici's reward? He was attacked and ostracized by the best. JAMA published false reports about his work. The American Cancer Society blasted him time and again. Meanwhile, word of mouth brought new patients to see him for decades.

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.

Much has been written about Neil Armstrong, America's modern hero and history's most famous space traveler. Yet, shy of fame and never one to steal the spotlight, Armstrong was always reluctant to discuss his personal side of events. Here for the first time is the definitive story of Neil's life of flight he shared for five decades with a trusted friend - Jay Barbree.

A compelling look inside the Space Shuttle missions that helped lay the groundwork for the Space Age, Shuttle, Houston explores the determined personalities, technological miracles, and 11th-hour saves that have given us human spaceflight. Relaying stories of missions (and their grueling training) in vivid detail, Paul Dye, NASA's longest-serving flight director, examines the split-second decisions that the directors and astronauts were forced to make in a field where mistakes are unthinkable and errors led to the loss of national resources - and more importantly one's crew.

Christopher A. Roosa grew up the eldest son of Apollo 14 astronaut and command module pilot Stuart A. Roosa. As a child of the space program, Christopher had a ringside seat at the dinner table of one of twenty-four Americans who had either entered lunar orbit or landed on the moon.

In Part of the Pride, Kevin Richardson, dubbed "The Lion Man" on 60 Minutes, tells the story of how he grew from a young boy who loved animals to become a man able to cross the divide between humans and predators, looking some of the world's most dangerous animals directly in the eye, playing with them, and even kissing them on the nose - all without ever being attacked or injured.

Inspired by Albert Einstein's theory of relativity and Bertrand Russell and David Hilbert's pursuit of the fundamental rules of mathematics, some of the most brilliant minds of the generation came together in post-World War I Vienna to present the latest theories in mathematics, science, and philosophy and to build a strong foundation for scientific investigation. Composed of such luminaries as Kurt Gödel and Rudolf Carnap, and stimulated by the works of Ludwig Wittgenstein and Karl Popper, the Vienna Circle left an indelible mark on science.

Since the fall of the Soviet Union, long-suppressed information has emerged on Heisenberg’s role in the Nazi atomic bomb project. In Beyond Uncertainty, Cassidy interprets this and other previously unknown material within the context of his vast research and tackles the vexing questions of a scientist’s personal responsibility and guilt when serving an abhorrent military regime.

From Leonardo Da Vinci to John Dee and Comenius, from George Eliot to Oliver Sacks and Susan Sontag, polymaths have moved the frontiers of knowledge in countless ways. But history can be unkind to scholars with such encyclopaedic interests. All too often these individuals are remembered for just one part of their valuable achievements. In this engaging, erudite account, renowned cultural historian Peter Burke argues for a more rounded view.

Author Jeremy Gray provides a comprehensive and intellectually stimulating introduction to Bernhard Riemann’s life and paradigm-defining work. Beginning with his early influences - in particular, his relationship with his renowned predecessor Carl Friedrich Gauss - Gray goes on to explore Riemann’s specific contributions to geometry, functions of a complex variable, prime numbers, and functions of a real variable, which opened the way to discovering the limits of the calculus.

Pendant un an, six scientifiques et ingénieurs ont vécu isolés dans un dôme blanc de onze mètres de diamètre perché sur le volcan Mauna Loa, à Hawaii. Durant cette période, ils n'ont jamais été à l'air libre puisque, lors de leurs sorties à l'extérieur au cours desquelles ils exploraient des tunnels de lave et effectuaient diverses tâches scientifiques, ils portaient une combinaison spatiale. Ils n'avaient en stock que de la nourriture déshydratée.

"Spectacular" is a mild word for describing the strange experiment with life that comprises the story of Nikola Tesla, and "amazing" fails to do adequate justice to the results that burst from his experiences like an exploding rocket. It is the story of the dazzling scintillations of a superman who created a new world.
