Bøger af Amir D. Aczel

Called "one of our best science popularizers" by Publishers Weekly, Amir D. Aczel tackles the cause of one of last century's most destructive events--the scientific discovery of nuclear power. Drawing on his rich storytelling skills, Aczel presents the fascinating and suspenseful story of the scientists who first uncovered the potential of uranium. Uranium Wars takes the reader on a whirlwind tour of 1920s Europe where the scientific elite of the day were embroiled in a fierce rivalry to achieve nuclear fission. Leading us to an understanding of both the processes that take place inside a uranium nucleus and its destructive power are the brilliant men and women at the heart of the race--mammoth figures such as Marie Curie, Enrico Fermi, and Lise Meitner. Enmeshed in the story of scientific intrigue is the complex and ongoing story of uranium itself, which Aczel presents as a dynamic, dual natured force, capable of providing both abundant usable energy and generating unfathomable destructive power. From the nuclear programs in the Middle East to plans for nuclear reactors at home, the element uranium is never far from today's headlines.

The story of the compass is shrouded in mystery and myth, yet most will agree it begins around the time of the birth of Christ in ancient China. A mysterious lodestone whose powers affected metal was known to the Chinese emperor. When this piece of metal was suspended in water, it always pointed north. This unexplainable occurrence led to the stone's use in feng shui, the Chinese art of finding the right location. However, it was the Italians, more than a thousand years later, who discovered the ultimate destiny of the lodestone and unleashed its formidable powers. In Amalfi sometime in the twelfth century, the compass was born, crowning the Italians as the new rulers of the seas and heralding the onset of the modern world. Retracing the roots of the compass and sharing the fascinating story of navigation through the ages, The Riddle of the Compass is Aczel at his most entertaining and insightful.

For thousands of years, it was the visionaries and writers who argued that we cannot be alone-that there is intellegent life in the universe. Now, with the discoveries of the Hubble Telescope, data emerging from Mars, and knowledge about life at the extremes, scientists are taking up where they left off. Amir Aczel, author of Fermat's Last Theorem, pulls together everyting science has discovered, and mixes in proabability theory, to argure the case for the existence of intelligent life beyond this planet. Probability 1 is an extraordinary tour de force in which the author draws on cosmology, math, and biology to tell the rollicking good story of scientists tackling important scientific questions that help answer this fundamental question. What is the probability of intelligent life in the universe? Read this book, and you'll be convinced, by the power of the argument and the excitement of the science.

The dramatic story of French physicist Leon Foucault, the scientific genius whose famous pendulum would change the way we see our world forever.

René Descartes (1596-1650) is one of the towering and central figures in Western philosophy and mathematics. His apothegm "Cogito, ergo sum” marked the birth of the mind-body problem, while his creation of so-called Cartesian coordinates have made our physical and intellectual conquest of physical space possible.But Descartes had a mysterious and mystical side, as well. Almost certainly a member of the occult brotherhood of the Rosicrucians, he kept a secret notebook, now lost, most of which was written in code. After Descartes's death, Gottfried Leibniz, inventor of calculus and one of the greatest mathematicians in history, moved to Paris in search of this notebook—and eventually found it in the possession of Claude Clerselier, a friend of Descartes. Leibniz called on Clerselier and was allowed to copy only a couple of pages—which, though written in code, he amazingly deciphered there on the spot. Leibniz's hastily scribbled notes are all we have today of Descartes's notebook, which has disappeared.Why did Descartes keep a secret notebook, and what were its contents? The answers to these questions lead Amir Aczel and the reader on an exciting, swashbuckling journey, and offer a fascinating look at one of the great figures of Western culture.

The Large Hadron Collider (LHC) is the biggest, and by far the most powerful, machine ever built. A project of CERN, the European Organization for Nuclear Research, its audacious purpose is to re-create, in a 16.5-mile-long circular tunnel under the French-Swiss countryside, the immensely hot and dense conditions that existed some 13.7 billion years ago within the first trillionth of a second after the fiery birth of our universe. In Present at the Creation, Amir D. Aczel takes us inside the control rooms, as an international team of researchers begins to discover whether a multibillion-euro investment will fulfill its promise: to find empirical confirmation of theories in physics and cosmology. Through the eyes and words of the men and women who conceived and built CERN and the LHC, Aczel enriches all of us with a firm grounding in the scientific concepts necessary to appreciate fully the stunning July 4, 2012 discovery of the Higgs Boson. Newly updated in the wake of the discovery, Present at the Creation tells the story of perhaps the greatest experiment in the history of science.
