Showing results for "man" in History

The story of the men and women who drove the Voyager spacecraft mission, told by a scientist who was there from the beginning. The Voyager spacecraft are our farthest-flung emissaries--11.3 billion miles away from the crew who built and still operate them decades after their launch.

One of the great mysteries of science is that its fundamental laws are written in the language of mathematics. Graham Farmelo's thrilling new book shows how modern maths has helped physicists to rethink gravity, space, and time. The Universe Speaks in Numbers takes us on an adventure from the Enlightenment to the present with a vibrant cast of characters, illuminating the most exciting and controversial developments in contemporary thought.

Many of us know little about Archimedes other than his "Eureka" exclamation upon discovering that he could immerse an object in a full tub of water and measure the spillage to determine the object's weight. That seemingly simple observation not only proved to King Hieron II of Syracuse that a certain amount of silver had been used in what was supposed to be his solid-gold crown, it established the key principles of buoyancy that govern the flotation of hot-air balloons, ships, and denizens of the sea.

This 50th anniversary edition of Men, Machines, and Modern Times, though ultimately concerned with a positive alternative to an Orwellian 1984, offers an entertaining series of historical accounts taken from the 19th century to highlight a main theme: the nature of technological change, the fission brought about in society by such change, and society's reaction to that change.

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 complexity of mathematics - its abstract rules and obscure symbols - can seem very distant from the everyday. There are those things that are real and present, it is supposed, and then there are mathematical concepts: creations of our mind, mysterious tools for those unengaged with the world. Yet, from its most remote history and deepest purpose, mathematics has served not just as a way to understand and order, but also as a foundation for the reality it describes.

By the end of World War I, Albert Einstein had become the face of the new science of theoretical physics and had made some powerful enemies. One of those enemies, Nobel Prize winner Philipp Lenard, spent a career trying to discredit him. Their story of conflict, pitting Germany's most widely celebrated Jew against the Nazi scientist who was to become Hitler's chief advisor on physics, had an impact far exceeding what the scientific community felt at the time.

We inherit mechanisms for survival from our primeval past - none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: It changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking - all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world.

Pioneering oceanographer Curtis Ebbesmeyer unravels the mystery of marine currents, uncovers the astonishing story of flotsam, and changes the world's view of trash, the ocean, and our global environment. Curtis Ebbesmeyer is no ordinary scientist. He's been a consulting oceanographer for multinational firms and a lead scientist on international research expeditions, but he's never held a conventional academic appointment.

Johns Hopkins University, one of the preeminent medical schools in the nation today, has played a unique role in the history of medicine. When it first opened its doors in 1893, medicine was a rough-and-ready trade. It would soon evolve into a rigorous science. In recent years, medical science has mapped the human genome, deployed robotic tools to perform delicate surgeries, and developed effective vaccines against a host of deadly pathogens. But this transformation could not have happened without the game-changing vision, talent, and dedication of a small cadre of individuals.
