QFT is the only physics theory that makes sense and that dispels or resolves the paradoxes of relativity and quantum mechanics that have confused and mystified so many people.

    Like you, the elements have lives: personalities and attitudes, talents and shortcomings, stories rich with meaning. You may think of them as the inscrutable letters of the periodic table but you know them much better than you realise. Welcome to a dazzling tour through history and literature, science and art. Here you'll meet iron that rains from the heavens and noble gases that light the way to vice. You'll learn how lead can tell your future while zinc may one day line your coffin. You'll discover what connects the bones in your body with the Whitehouse in Washington, the glow of a streetlamp with the salt on your dinner table. From ancient civilisations to contemporary culture, from the oxygen of publicity to the phosphorus in your pee, the elements are near and far and all around us. Unlocking their astonishing secrets and colourful pasts, Periodic Tales will take you on a voyage of wonder and discovery, excitement and novelty, beauty and truth. Along the way, you'll find that their stories are our stories, and their lives are inextricable from our own.

    One of the world's leading astronomers, Robert Kirshner, takes readers inside a lively research team on the quest that led them to an extraordinary cosmological discovery: the expansion of the universe is accelerating under the influence of a dark energy that makes space itself expand. In addition to sharing the story of this exciting discovery, Kirshner also brings the science up-to-date in a new epilogue. He explains how the idea of an accelerating universe--once a daring interpretation of sketchy data--is now the standard assumption in cosmology today.This measurement of dark energy--a quality of space itself that causes cosmic acceleration--points to a gaping hole in our understanding of fundamental physics. In 1917, Einstein proposed the cosmological constant to explain a static universe. When observations proved that the universe was expanding, he cast this early form of dark energy aside. But recent observations described first-hand in this book show that the cosmological constant--or something just like it--dominates the universe's mass and energy budget and determines its fate and shape.Warned by Einstein's blunder, and contradicted by the initial results of a competing research team, Kirshner and his colleagues were reluctant to accept their own result. But, convinced by evidence built on their hard-earned understanding of exploding stars, they announced their conclusion that the universe is accelerating in February 1998. Other lines of inquiry and parallel supernova research now support a new synthesis of a cosmos dominated by dark energy but also containing several forms of dark matter. We live in an extravagant universe with a surprising number of essential ingredients: the real universe we measure is not the simplest one we could imagine.

    The more we discover, the more puzzling the universe appears to be. How and why are the laws of nature what they are? A philosopher and a physicist, world-renowned for their radical ideas in their fields, argue for a revolution. To keep cosmology scientific, we must replace the old view in which the universe is governed by immutable laws by a new one in which laws evolve. Then we can hope to explain them. The revolution that Roberto Mangabeira Unger and Lee Smolin propose relies on three central ideas. There is only one universe at a time. Time is real: everything in the structure and regularities of nature changes sooner or later. Mathematics, which has trouble with time, is not the oracle of nature and the prophet of science; it is simply a tool with great power and immense limitations. The argument is readily accessible to non-scientists as well as to the physicists and cosmologists whom it challenges.

    The ability to duplicate that process in a lab, once thought impossible, may now be closer than we think. Today, teams of scientists around the world are being assembled by the boldest entrepreneurs, big business, and governments to solve what is the most difficult technological challenge humanity has ever faced: building the equivalent of a star on earth. If their plans to capture star power are successful, they will unlock thousands, potentially millions, of years of clean, carbon-free energy. Not only would controlled nuclear fusion help solve the climate crisis, it could also make other highly desired technological ambitions possible—like journeying to the stars. Given the rising alarm over deterioration of the environment, and the strides being made in laser and magnetic field technology, powerful momentum is gathering behind fusion and the possibilities it offers. In The Star Builders, award-winning young plasma physicist Arthur Turrell “offers an optimistic outlook for the future of fusion power and is adamant about the need to invest in it” (The New York Times). Turrell describes fascinating star machines with ten times as many parts as the NASA Space Shuttle, and structures that extend over 400 acres in an accessible and entertaining account, spotlighting the individuals, firms, and institutions racing for the finish line: science-minded entrepreneurs like Jeff Bezos and Peter Thiel, companies like Goldman Sachs and Google, universities like Oxford and MIT, and virtually every rich nation. It’s an exciting and game-changing international quest that will make all of us winners.

    From Quantum Mechanics to Natural Selection, what we have instead are theories - ideas explain why things happen the way they do. We don't know for certain these are correct - no one ever saw the Big Bang - but with them we can paint beautiful, breathtaking pictures of everything from human behaviour to what the future may hold. Profiling the key scientists behind each theory, "30-Second Theories" presents each entry in a unique, eye-catching full-colour design, with thought-provoking extras and stylish illustrations. It is essential for anyone keen on expanding their mind with science's most thrilling ideas.

    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."

    As much as anyone in the modern era, he changed human thought, and his influence is still felt in virtually all aspects of our lives. This new edition, larger and more varied than the previous ones, includes more of Darwin's own work and also presents the most recent research and scholarship on all aspects of Darwin’s legacy. The biological sciences, as well as social thought, philosophy, ethics, religion, and literature, have all been shaped and reshaped by evolutionary concepts.Excerpts from the most important books and articles of recent years confirm this Darwinian heritage. New work by Richard Dawkins, Edward O. Wilson, Kevin Padian, Eugene C. Scott, Steven Pinker, Daniel Dennett, Michael Ruse, Frans de Waal, Noretta Koertge, George C. Williams, George Levine, Stephen Jay Gould, Gillian Beer, Ernst Mayr, and many others illuminates this exciting intellectual history. A wide-ranging new introduction by the editor provides context and coherence to this rich body of engaging material, much of which will be shaping human thought well into the new century.This collection of Darwin's writing, those of his critics and those of his intellectual descendants, includes:- The Voyage of the Beagle (1845): Ch. I, XVII- On the Tendency of Species to Form Varieties; And on the Perpetuation of Varieties and Species by Natural Means of Selection (1858): Ch. I-II- An Historical Sketch of the Progress of Opinion on the Origin of Species Previously to the Publication of this Work (1861) The Origin of Species (1859): Introduction, Ch.

    But gravitational waves – ripples in the fabric of space and time – are unrelenting, passing through barriers that stop light dead.At the two 4-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015 they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering.This was the first time black holes had ever been directly detected – and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a new, powerful path to understand the workings of the universe.Brian Clegg’s most recent books are The Reality Frame (Icon, 2017), What Colour is the Sun? (Icon, 2016) and Ten Billion Tomorrows (St Martin’s Press, 2016). His Dice World and A Brief History of Infinity were both longlisted for the Royal Society Prize for Science Books. He has also written Big Data for the Hot Science series. Brian has written for numerous publications including The Wall Street Journal, Nature, BBC Focus, Physics World, The Times and The Observer.

    A meld of history and science, this book is a group portrait of some of the greatest minds who ever lived as they wrestled with nature’s most sweeping mysteries. The answers they uncovered still hold the key to how we understand the world.At the end of the seventeenth century—an age of religious wars, plague, and the Great Fire of London—when most people saw the world as falling apart, these earliest scientists saw a world of perfect order. They declared that, chaotic as it looked, the universe was in fact as intricate and perfectly regulated as a clock. This was the tail end of Shakespeare’s century, when the natural land the supernatural still twined around each other. Disease was a punishment ordained by God, astronomy had not yet broken free from astrology, and the sky was filled with omens. It was a time when little was known and everything was new. These brilliant, ambitious, curious men believed in angels, alchemy, and the devil, and they also believed that the universe followed precise, mathematical laws—-a contradiction that tormented them and changed the course of history.The Clockwork Universe is the fascinating and compelling story of the bewildered geniuses of the Royal Society, the men who made the modern world.

    In elegant, witty three-page summations, Dr. Trefil "makes sense of science for the rest of us" (Washington Post).

    That they exist, Simon Singh reveals, underscores the brilliance of the shows' writers, many of whom have advanced degrees in mathematics in addition to their unparalleled sense of humor. While recounting memorable episodes such as “Bart the Genius” and “Homer3,” Singh weaves in mathematical stories that explore everything from p to Mersenne primes, Euler's equation to the unsolved riddle of P v. NP; from perfect numbers to narcissistic numbers, infinity to even bigger infinities, and much more. Along the way, Singh meets members of The Simpsons' brilliant writing team-among them David X. Cohen, Al Jean, Jeff Westbrook, and Mike Reiss-whose love of arcane mathematics becomes clear as they reveal the stories behind the episodes. With wit and clarity, displaying a true fan's zeal, and replete with images from the shows, photographs of the writers, and diagrams and proofs, The Simpsons and Their Mathematical Secrets offers an entirely new insight into the most successful show in television history.

    In doing so, the authors synthesize information from astronomy, biology, and paleontology, and apply it to what we know about the rise of life on Earth and to what could possibly happen elsewhere in the universe. Everyone who has been thrilled by the recent discoveries of extrasolar planets and the indications of life on Mars and the Jovian moon Europa will be fascinated by Rare Earth, and its implications for those who look to the heavens for companionship.

    Written by one of the world's leading experimental cosmologists, this short but deeply insightful book describes what scientists are revealing through precise measurements of the faint thermal afterglow of the Big Bang--known as the cosmic microwave background, or CMB--and how their findings are transforming our view of the cosmos.Blending the latest findings in cosmology with essential concepts from physics, Lyman Page first helps readers to grasp the sheer enormity of the universe, explaining how to understand the history of its formation and evolution in space and time. Then he sheds light on how spatial variations in the CMB formed, how they reveal the age, size, and geometry of the universe, and how they offer a blueprint for the formation of cosmic structure.Not only does Page explain current observations and measurements, he describes how they can be woven together into a unified picture to form the Standard Model of Cosmology. Yet much remains unknown, and this incisive book also describes the search for ever deeper knowledge at the field's frontiers--from quests to understand the nature of neutrinos and dark energy to investigations into the physics of the very early universe.
