Pendulum

by Amir D. Aczel

He was neither a mathematician nor a trained physicist and yet Léon Foucault always knew that a mysterious force of nature was among us. Like Newton, Galileo, Copernicus, and others before him, Foucault sensed a dramatic relationship between the rotating skies above and the seemingly motionless ground beneath our feet. But it wasn't until 1851 -- in Paris, inside the Panthéon, and in the company of fellow amateur scientist Napoleon III -- that Foucault swung a pendulum and demonstrated an extraordinary truth about the world: that it turns on its axis. Pendulum is a fascinating journey through the mind and findings of one of the most important and lesser-known characters in the history of science. Through careful research and lively anecdotes, world-renowned author Amir D. Aczel reveals the astonishing range and breadth of Foucault's discoveries. For, in addition to offering the first unequivocal proof of Earth's rotation, Foucault gave us the modern electric compass and microscope, was a pioneer in photographic technology, and made remarkable deductions about color theory, heat waves, and the speed of light. At its heart, Pendulum is a story about the illustrious period in France during the Second Empire; the crucial triumph of science over religion; and, most compelling, the life of a struggling, self-made man whose pursuit of knowledge continues to inform our notions about the universe today.

Present at the Creation: Discovering the Higgs Boson

by Amir D. Aczel

The Large Hadron Collider 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. The collider is now crashing protons at record energy levels never created by scientists before, and it will reach even higher levels by 2013. Its superconducting magnets guide two beams of protons in opposite directions around the track. After accelerating the beams to 99.9999991 percent of the speed of light, it collides the protons head-on, annihilating them in a flash of energy sufficient--in accordance with Einstein's elegant statement of mass-energy equivalence, E=mc2--to coalesce into a shower of particles and phenomena that have not existed since the first moments of creation. Within the LHC's detectors, scientists hope to see empirical confirmation of key theories in physics and cosmology.In telling the story of what is perhaps the most anticipated experiment in the history of science, Amir D. Aczel takes us inside the control rooms at CERN at key moments when an international team of top researchers begins to discover whether this multibillion-euro investment will fulfill its spectacular promise. Through the eyes and words of the men and women who conceived and built CERN and the LHC--and with the same clarity and depth of knowledge he demonstrated in the bestselling Fermat's Last Theorem--Aczel enriches all of us with a firm grounding in the scientific concepts we will need to appreciate the discoveries that will almost certainly spring forth when the full power of this great machine is finally unleashed.Will the Higgs boson make its breathlessly awaited appearance, confirming at last the Standard Model of particles and their interactions that is among the great theoretical achievements of twentieth-century physics? Will the hidden dimensions posited by string theory be revealed? Will we at last identify the nature of the dark matter that makes up more than 90 percent of the cosmos? With Present at the Creation, written by one of today's finest popular interpreters of basic science, we can all follow the progress of an experiment that promises to greatly satisfy the curiosity of anyone who ever concurred with Einstein when he said, "I want to know God's thoughts--the rest is details."From the Hardcover edition.

Why Science Does Not Disprove God

by Amir D. Aczel

The renowned science writer, mathematician, and bestselling author of Fermat's Last Theorem masterfully refutes the overreaching claims the "New Atheists," providing millions of educated believers with a clear, engaging explanation of what science really says, how there's still much space for the Divine in the universe, and why faith in both God and empirical science are not mutually exclusive.A highly publicized coterie of scientists and thinkers, including Richard Dawkins, the late Christopher Hitchens, and Lawrence Krauss, have vehemently contended that breakthroughs in modern science have disproven the existence of God, asserting that we must accept that the creation of the universe came out of nothing, that religion is evil, that evolution fully explains the dazzling complexity of life, and more. In this much-needed book, science journalist Amir Aczel profoundly disagrees and conclusively demonstrates that science has not, as yet, provided any definitive proof refuting the existence of God.Why Science Does Not Disprove God is his brilliant and incisive analyses of the theories and findings of such titans as Albert Einstein, Roger Penrose, Alan Guth, and Charles Darwin, all of whose major breakthroughs leave open the possibility— and even the strong likelihood—of a Creator. Bolstering his argument, Aczel lucidly discourses on arcane aspects of physics to reveal how quantum theory, the anthropic principle, the fine-tuned dance of protons and quarks, the existence of anti-matter and the theory of parallel universes, also fail to disprove God.

The Artist and the Mathematician

by Amir Aczel

Nicolas Bourbaki, whose mathematical publications began to appear in the late 1930s and continued to be published through most of the twentieth century, was a direct product as well as a major force behind an important revolution that took place in the early decades of the twentieth century that completely changed Western culture. Pure mathematics, the area of Bourbaki's work, seems on the surface to be an abstract field of human study with no direct connection with the real world. In reality, however, it is closely intertwined with the general culture that surrounds it. Major developments in mathematics have often followed important trends in popular culture; developments in mathematics have acted as harbingers of change in the surrounding human culture. The seeds of change, the beginnings of the revolution that swept the Western world in the early decades of the twentieth century -- both in mathematics and in other areas -- were sown late in the previous century. This is the story both of Bourbaki and the world that created him in that time. It is the story of an elaborate intellectual joke -- because Bourbaki, one of the foremost mathematicians of his day -- never existed.

The Jesuit and the Skull

by Amir Aczel

From the New York Times bestselling author of Fermat's Last Theorem, "an extraordinary story"( Philadelphia Inquirer) of discovery, evolution, science, and faith. In 1929, French Jesuit priest Pierre Teilhard de Chardin was a part of a group of scientists that uncovered a skull that became known as Peking Man, a key evolutionary link that left Teilhard torn between science and his ancient faith, and would leave him ostracized by his beloved Catholic Church. His struggle is at the heart of The Jesuit and the Skull, which takes readers across continents and cultures in a fascinating exploration of one of the twentieth century's most important discoveries, and one of the world's most provocative pieces of evidence in the roiling debate between creationism and evolution.

Coulometric Electrode Array Detectors for HPLC

by I. N. Acworth M. Naoi H. Parvez S. Parvez

This sixth volume in the book series Progress in HPLC-HPCE examines the enhancement of high- performance liquid chromatography through the development of an advanced mode of electrochemical detection (ECD) --- the coulometric array detection --- from its initial, yet problematic, amperometric (thin-layer) design to the highly sensitive, selective and stable coulometric (flow-through) design. Unlike amperometric electrodes, the coulometric electrode is 100% efficient and measures signals from all of the analyte passing through it, which leads to improved sensitivity as well as unique selectivity. The coulometric electrode array offers the resolution of the photodiode array with the extreme sensitivity of an electrochemical detector.

The Mercury 13: The Untold Story of Thirteen American Women and the Dream of Space Flight

by Martha Ackmann

For readers of The Astronaut Wives Club, The Mercury 13 reveals the little-known true story of the remarkable women who trained for NASA space flight. <p><p> In 1961, just as NASA launched its first man into space, a group of women underwent secret testing in the hopes of becoming America’s first female astronauts. They passed the same battery of tests at the legendary Lovelace Foundation as did the Mercury 7 astronauts, but they were summarily dismissed by the boys’ club at NASA and on Capitol Hill. The USSR sent its first woman into space in 1963; the United States did not follow suit for another twenty years. <p><p> For the first time, Martha Ackmann tells the story of the dramatic events surrounding these thirteen remarkable women, all crackerjack pilots and patriots who sometimes sacrificed jobs and marriages for a chance to participate in America’s space race against the Soviet Union. In addition to talking extensively to these women, Ackmann interviewed Chuck Yeager, John Glenn, Scott Carpenter, and others at NASA and in the White House with firsthand knowledge of the program, and includes here never-before-seen photographs of the Mercury 13 passing their Lovelace tests. <p><p> Despite the crushing disappointment of watching their dreams being derailed, the Mercury 13 went on to extraordinary achievement in their lives: Jerrie Cobb, who began flying when she was so small she had to sit on pillows to see out of the cockpit, dedicated her life to flying solo missions to the Amazon rain forest; Wally Funk, who talked her way into the Lovelace trials, went on to become one of the first female FAA investigators; Janey Hart, mother of eight and, at age forty, the oldest astronaut candidate, had the political savvy to steer the women through congressional hearings and later helped found the National Organization for Women. <p><p> A provocative tribute to these extraordinary women, The Mercury 13 is an unforgettable story of determination, resilience, and inextinguishable hope.

Sergei Vinogradskii and the Cycle of Life

by Lloyd Ackert

This is one of those biographies that provide a window onto the broader understanding of science in its social and cultural context. Using Sergei Nikolaevich Vinogradskii's career and scientific research trajectory as a point of entry, this book illustrates the manner in which microbiologists, chemists, botanists, and plant physiologists inscribed the concept of a "cycle of life" into their investigations. Their research transformed a longstanding notion into the fundamental approaches and concepts that underlay the new ecological disciplines that emerged in the 1920s. The book presents a reconstruction of significant episodes of Vinogradskii's laboratory practices and the role of theory in their development. It paints the broader picture of the history of ecology, microbiology and soil science and how these are uniquely united: through the concept of the cycle of life.
