In this propulsive, “nonstop read” (USA TODAY) from the New York Times bestselling author of The Shape of Night, a NASA doctor is in a deadly race against time to destroy a lethal microbe as it multiplies in the International Space Station. Dr. Emma Watson’s lifelong dream of working and studying aboard the International Space Station has finally come true. But it quickly becomes a nightmare when a culture of single-celled organisms begins to regenerate out of control—and infects the crew. Emma must contain the outbreak and prevent as many deaths as possible while, back on Earth, her estranged husband is frantically working with NASA to bring her home. But with a contagion threatening all of humanity, there will be no rescue. “Thrilling…fast-paced, scary, and loaded with insider information” (The Plain Dealer, Cleveland), Gravity is an unputdownable thriller that will keep you on the edge of your seat until the final page.

The correct interpretation of Kepler's third law is Gravitational force is equal to acceleration times the area: F = a .A. It is shown that the sequential mean distances of the planets from the center of the sun follow an exponential law, concluding that gravitation is quantized. New explanation and equation for eccentricity are presented. English translation of Foucault's papers on the pendulum and on the gyroscope

Einstein's gravity theory—his general theory of relativity—has served as the basis for a series of astonishing cosmological discoveries. But what if, nonetheless, Einstein got it wrong? Since the 1930s, physicists have noticed an alarming discrepancy between the universe as we see it and the universe that Einstein's theory of relativity predicts. There just doesn't seem to be enough stuff out there for everything to hang together. Galaxies spin so fast that, based on the amount of visible matter in them, they ought to be flung to pieces, the same way a spinning yo-yo can break its string. Cosmologists tried to solve the problem by positing dark matter—a mysterious, invisible substance that surrounds galaxies, holding the visible matter in place—and particle physicists, attempting to identify the nature of the stuff, have undertaken a slew of experiments to detect it. So far, none have. Now, John W. Moffat, a physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, offers a different solution to the problem. The cap­stone to a storybook career—one that began with a correspondence with Einstein and a conversation with Niels Bohr—Moffat's modified gravity theory, or MOG, can model the movements of the universe without recourse to dark matter, and his work chal­lenging the constancy of the speed of light raises a stark challenge to the usual models of the first half-million years of the universe's existence. This bold new work, presenting the entirety of Moffat's hypothesis to a general readership for the first time, promises to overturn everything we thought we knew about the origins and evolution of the universe.

Covering all aspects of gravitation in a contemporary style, this advanced textbook is ideal for graduate students and researchers in all areas of theoretical physics. The 'Foundation' section develops the formalism in six chapters, and uses it in the next four chapters to discuss four key applications - spherical spacetimes, black holes, gravitational waves and cosmology. The six chapters in the 'Frontier' section describe cosmological perturbation theory, quantum fields in curved spacetime, and the Hamiltonian structure of general relativity, among several other advanced topics, some of which are covered in-depth for the first time in a textbook. The modular structure of the book allows different sections to be combined to suit a variety of courses. Over 200 exercises are included to test and develop the reader's understanding. There are also over 30 projects, which help readers make the transition from the book to their own original research.

It was just a hoverboard. Nobody was supposed to die. Dale Adams has worked hard to leave his troubled past behind for a brighter future at Emory University. But when he makes a discovery that will change humanity forever, avoiding the spotlight becomes the least of his concerns. Small experiments have attracted big attention. And not all who notice want Dale to be successful. Or even alive. As Dale's world collapses around him, his fate intertwines with that of a girl he hardly knows. Their only hope for survival is to disappear into Atlanta's seedy underbelly, the very place Dale has tried so hard to leave behind. Time is running out, but if they can survive long enough science will be rewritten by the most unlikely of authors. ____________________ ❝ ...grabs you by the throat early on and doesn't let go! ❞ ~ Al Letson, Host of Reveal on NPR

Greg used to be an angel, but that was an eternity ago. Back when he was Araqiel, part of the celestial chorus. Back before he gave in to his temptations. Before he fell. Now he roams the wet streets of a hopeless city, feeding his addictions and punishing himself for sins that cannot be forgiven. But when a desperate girl and a host of vengeful demons cross his path, Greg must choose between redemption and damnation. For him, the two may not be so different.

A debut novel already destined to be a book club favorite. “With its deft interweaving of psychological complexity and riveting narrative momentum, with its gorgeous prose and poetic justice, The Gravity of Birds is about sibling rivalry, tragedies, and resurrections. And it’s irresistibly exquisite” (San Francisco Chronicle). Forty-four years after the brilliant young painter, Thomas Bayber, first meets Alice and Natalie Kessler, Bayber unveils a never-before-seen work, Kessler Sisters—a provocative painting depicting the young Thomas, Alice, and Natalie. Bayber asks Dennis Finch, an art history professor, and Stephen Jameson, an eccentric young art authenticator, to sell the painting. But their task becomes more complicated when the artist requires that they first locate Alice and Natalie, who seem to have disappeared. Told in alternating chapters that weave revelations about the sisters’ past with clues Finch and Jameson discover in the present, this story sets three characters on a collision course with their histories, showing how families tear themselves apart and then try to bind themselves together again, not always creating the same fabric. The Gravity of Birds “combines the drama of warring sisters, the mystery of a missing painting, and the sorrow of lost love into a haunting elegy that will…leave you breathless” (Tiffany Baker, author of The Little Giant of Aberdeen County).

A key unresolved issue lies at the heart of our science -- the quest of Aristotle, Newton, Einstein, Hawking and many others, now widely known as the Theory of Everything. This ultimate understanding is expected to transform science and resolve its many mysteries -- all via one single overlooked principle in nature that will explain, simplify and unify everything. This quest has produced theories such as Special Relativity, General Relativity and Quantum Mechanics, enormous investments in powerful particle accelerators and space telescopes, and such recent pursuits as "Dark Matter" and "Dark Energy." But enormous problems remain: these theories, projects and pursuits are all completely separate and frequently incompatible, presenting unresolved abstractions, speculation, paradoxes and mysteries that often even violate our laws of physics, upon closer examination. As a result, the Theory of Everything continues to elude us, with no clear way forward. The Final Theory clearly shows why this is the case, exposing centuries of well-intentioned but misguided scientific thought that has locked us into an erroneous and highly troubled energy-based science that has taken us far off track. It corrects the errors in our scientific legacy, showing that energy is actually a misunderstanding of the unifying principle we have sought for centuries -- a principle that is active all around us, producing all known phenomena such as gravity, light, electricity and magnetism. This new understanding replaces both Newton's "gravitational force" theory and Einstein's "warped space-time" General Relativity Theory, while also overturning such theories as Special Relativity and Quantum Mechanics. In their place is a single simple principle that finally demystifies, explains and unifies everything. Read The Final Theory and judge for yourself whether the Theory of Everything has finally arrived!
