For centuries, the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. Zero follows this number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe and its apotheosis as the mystery of the black hole. Today, zero lies at the heart of one of the biggest scientific controversies of all time, the quest for the theory of everything. Elegant, witty, and enlightening, Zero is a compelling look at the strangest number in the universe and one of the greatest paradoxes of human thought.

    This new edition of the bible of bicycle builders and bicyclists provides just about everything you could want to know about the history of bicycles, how human beings propel them, what makes them go faster, and what keeps them from going even faster. The scientific and engineering information is of interest not only to designers and builders of bicycles and other human-powered vehicles but also to competitive cyclists, bicycle commuters, and recreational cyclists.The third edition begins with a brief history of bicycles and bicycling that demolishes many widespread myths. This edition includes information on recent experiments and achievements in human-powered transportation, including the ultimate human- powered vehicle, in which a supine rider in a streamlined enclosure steers by looking at a television screen connected to a small camera in the nose, reaching speeds of around 80 miles per hour. It contains completely new chapters on aerodynamics, unusual human-powered machines for use on land and in water and air, human physiology, and the future of bicycling. This edition also provides updated information on rolling drag, transmission of power from rider to wheels, braking, heat management, steering and stability, power and speed, and materials. It contains many new illustrations.

    Hailed as "unsinkable, " the "Kursk" was on maneuvers when mysterious explosions rocked the sub, causing it to sink to the bottom of the sea with its 118-man crew. This in-depth look at the disaster reveals previously unreleased information from family members of the deceased as well as from government officials.

    The savagery of this electrical battle can hardly be imagined today. The showdown between AC and DC began as a rather straightforward conflict between technical standards, a battle of competing methods to deliver essentially the same product, electricity. But the skirmish soon metastasized into something bigger and darker. In the AC/DC battle, the worst aspects of human nature somehow got caught up in the wires; a silent, deadly flow of arrogance, vanity, and cruelty. Following the path of least resistance, the war of currents soon settled around that most primal of human emotions: fear. "AC/DC" serves as an object lesson in bad business strategy and poor decision making. Edison's inability to see his mistake was a key factor in his loss of control over the "operating system" for his future inventions—not to mention the company he founded, General Electric.

    His explanation of the role of natural selection in driving the evolution of life on earth depended on steady variation of living things over time – but he was unable to explain how this variation occurred. In the 150 years since publication of the Origin of Species, we have discovered three main sources for this variation – mutation, hybridisation and epigenetics. Then on Sunday, 12th February, 2001 the evidence for perhaps the most extraordinary cause of variation was simultaneously released by two organisations – the code for the entire human genome. Not only was the human genome unbelievably simple (it is only ten times more complicated than a bacteria), but embedded in the code were large fragments that were derived from viruses – fragments that were vital to evolution of all organisms and the evidence for a fourth and vital source of variation – viruses.Virolution was the subject of a feature article in New Scientist. Translated into Russian, French, German and Japanese, this book has become a hot topic for discussion among scientists and thinkers in recent years. It offers a very new interpretation of our human evolution - and extrapolates to new avenues of approach to fight important diseases, such as cancer and MS.In early 2014 Dr Ryan has co-authored a relevant new paper with Swedish and Chinese scientists working on the Human Proteome project. More details about this paper and other developments will follow in his articles and blogs. So popular is the topic he has been commissioned to give a plenary lecture followed by planning and research advice to PhD students in biology and evolutionary biology at the annual European Society for Evolutionary Biology annual meeting for PhD students in Belgium in September 2014.More anon...

    The plane slammed onto the runway and burst into a vast fireball. The rescuers didn't move at first: nobody could possibly survive that crash. And then people began emerging from the summer corn that lined the runways. Miraculously, 184 of 296 passengers lived.No one has ever attempted the complete reconstruction of a crash of this magnitude. Drawing on interviews with hundreds of survivors, crew, and airport and rescue personnel, Laurence Gonzales, a commercial pilot himself, captures, minute by minute, the harrowing journey of pilots flying a plane with no controls and flight attendants keeping their calm in the face of certain death. He plumbs the hearts and minds of passengers as they pray, bargain with God, plot their strategies for survival, and sacrifice themselves to save others.Ultimately he takes us, step by step, through the gripping scientific detective work in super-secret labs to dive into the heart of a flaw smaller than a grain of rice that shows what brought the aircraft down.An unforgettable drama of the triumph of heroism over tragedy and human ingenuity over technological breakdown, Flight 232 is a masterpiece in the tradition of the greatest aviation stories ever told.

    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.

    New emphasis has been given to complexity, networks, and patterns of organisation, leading to a novel kind of 'systemic' thinking. This volume integrates the ideas, models, and theories underlying the systems view of life into a single coherent framework. Taking a broad sweep through history and across scientific disciplines, the authors examine the appearance of key concepts such as autopoiesis, dissipative structures, social networks, and a systemic understanding of evolution. The implications of the systems view of life for health care, management, and our global ecological and economic crises are also discussed. Written primarily for undergraduates, it is also essential reading for graduate students and researchers interested in understanding the new systemic conception of life and its implications for a broad range of professions - from economics and politics to medicine, psychology and law.

    Over time, eight key technologies gradually freed us from the limitations of our animal origins.The fabrication of weapons, the mastery of fire, and the technologies of clothing and shelter radically restructured the human body, enabling us to walk upright, shed our body hair, and migrate out of tropical Africa. Symbolic communication transformed human evolution from a slow biological process into a fast cultural process. The invention of agriculture revolutionized the relationship between humanity and the environment, and the technologies of interaction led to the birth of civilization. Precision machinery spawned the industrial revolution and the rise of nation-states; and in the next metamorphosis, digital technologies may well unite all of humanity for the benefit of future generations.Synthesizing the findings of primatology, paleontology, archeology, history, and anthropology, Richard Currier reinterprets and retells the modern narrative of human evolution that began with the discovery of Lucy and other Australopithecus fossils. But the same forces that allowed us to integrate technology into every aspect of our daily lives have also brought us to the brink of planetary catastrophe. Unbound explains both how we got here and how human society must be transformed again to achieve a sustainable future.Technology: “The deliberate modification of any natural object or substance with forethought to achieve a specific end or to serve a specific purpose.”

    An analysis of the claims of science shows that this discipline is just as much about faith and belief (vs. fact) as is Christian doctrine. Quantum mechanics has rendered atheism obsolete and has provided us with insights concerning the possible nature and origin of the Biblical God. Einstein's Special Theory of Relativity has virtually proved that we all live forever in some kind of timeless state. Quantum observation, a consequence of quantum physics, has provided us with strong evidence that the true God is He of the Bible. Augustine of Hippo said that he probably would never have been converted were it not for Plato. Other theses entertained in this volume are that mind is primary in our world, which is the thought of God; that God emanates from The Truth, synonymous with goodness and all that is good for cognitive individuals; that faith is much more than blind belief in Him; and that the history of the Jews provides us with powerful evidence that they are the chosen people of the true God. Christianity is unique among religions in terms of reason, logic, and common sense. Here is an example of the writing to be found in my book: "Quantum observation is heavily involved with the concept of form and substance, something that greatly interested Plato. In our world, we can discern two aspects of a material object: substance, the "stuff" of which it is composed, and form, which is its shape. These two characteristics are always connected on the human level of size; according to our physical senses, any separation of them is ridiculous. On the bizarre quantum level, however, elemental entities can exist as form alone or as substance alone. When these are in the state of form, they are waves, and, when they assume the mode of substance, they exist as discrete packets--ultimately, of energy. These are distinct bodies of substance that we call quanta. I am privileged to have received an endorsement of my work from Charles Taliaferro, Chair, Department of Philosophy, St. Olaf College; Editor-in-Chief, Open Theology. It reads as follows: "Because medical doctors or physicians have made vital contributions to philosophy, from Maimonides, Avicenna, and John Locke in the history of philosophy to Raymond Tallis today, it should not surprise us to see Dr. James Frederick Ivey's superb contribution to our philosophical reflection on the bearing of current physics on Biblical faith. Perhaps it takes a person well trained in the application of science in medicine to see the ways in which the application of science, especially modern physics, quantum mechanics, and relativity have important applications in our thinking about God, the Bible, and Judeo-Christianity. The terrain is not unexplored by philosophers, theologians, and popular writers, but it is rare to see the kind of engaging clarity, breadth, and conscientious, mature reflection to be found in Ivey's book." I have a second professorial endorsement that reads thus: "In his book, The Physics and Philosophy of the Bible, Dr. James Ivey, although a physician, has done his homework in both the physical sciences and philosophy. He argues that modern physics, relativity and quantum mechanics, strongly infer the existence of God. He concludes that the historical man, Jesus of Nazareth, was not a lunatic or a liar, but truly God. He submits that Biblical Christianity has all the truth in it and is radically different from all other faiths. His book is a must read for those who have problems with science versus theology."

    But the president insisted there was nothing to worry about.Fortunately, we are still a nation of skeptics. Fortunately, there are those among us who study pandemics and are willing to look unflinchingly at worst-case scenarios. Michael Lewis’s taut and brilliant nonfiction thriller pits a band of medical visionaries against the wall of ignorance that was the official response of the Trump administration to the outbreak of COVID-19.The characters you will meet in these pages are as fascinating as they are unexpected. A thirteen-year-old girl’s science project on transmission of an airborne pathogen develops into a very grown-up model of disease control. A local public-health officer uses her worm’s-eye view to see what the CDC misses, and reveals great truths about American society. A secret team of dissenting doctors, nicknamed the Wolverines, has everything necessary to fight the pandemic: brilliant backgrounds, world-class labs, prior experience with the pandemic scares of bird flu and swine flu…everything, that is, except official permission to implement their work.Michael Lewis is not shy about calling these people heroes for their refusal to follow directives that they know to be based on misinformation and bad science. Even the internet, as crucial as it is to their exchange of ideas, poses a risk to them. They never know for sure who else might be listening in.

    The army blamed “human error†and a sordid love triangle. Though overshadowed by Three Mile Island, SL-1 remains the only fatal nuclear reactor incident in American history. Todd Tucker, who first heard the rumors about the Idaho Falls explosion as a trainee in the navy’s nuclear program, suspected there was more to the accident than rumors suggested. Poring over hundreds of pages of primary sources and interviewing survivors revealed that the army and its contractors had deliberately obscured the true cause of the accident, which resulted from poor engineering as much as uncontrolled passions. The National Reactor Testing Station, where the meltdown occurred, had been a proving ground where engineers, generals, and admirals attempted to realize the Atomic Age dream of unlimited power—amid the frantic race for nuclear power between the army, the navy, and the air force. The fruit of those ambitious plans included that of the nation’s unofficial nuclear patriarch, Admiral Rickover, whose “true submarine,†the USS Nautilus, would forever change naval warfare. But with the meltdown in Idaho came the end of the army’s program and the beginning of the navy’s long-standing monopoly on military nuclear power. Atomic America provides a fast-paced narrative history, advocating caution and accountability in harnessing nuclear energy.

    Louisa, a young maid at the hotel determined to befriend him, wins his attention through a shared love of pigeons; with her, we hear his tragic and tremendous life story unfold. Meanwhile, Louisa discovers that her father—and her handsome, enigmatic love interest, Arthur Vaughan—are on an unlikely mission to travel back in time and find his beloved late wife. A masterful hybrid of history, biography, and science fiction, The Invention of Everything Else is an absorbing story about love and death and a wonderfully imagined homage to one of history's most visionary scientists.
