Reinventing Gravity: A Physicist Goes Beyond Einstein


John W. Moffat - 2008
    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.

The 11th Science Fiction MEGAPACK®: 36 Modern and Classic Science Fiction Stories


Fritz Leiber - 2016
    There's a greater emphasis than usual on Golden Age writers (just the way it came together) -- but we have one original story as well, a posthumous collaboration with H.B. Fyfe, finishing a really terrific but not-quite-done tale he had been working on before his death. It's a bit reminiscent of James Tiptree, Jr.'s best work -- but predates Tiptree by a couple of decades. And we have novels by Robert Silverberg, Frederik Pohl & C.M. Kornbluth, Murray Leinster, E. Everett Evans, and Donald Wollheim...not to mention part 2 of our serialization of Tony Rothman's mammoth 2013 novel, Firebird. And a ton of great short stories. 36 works in all, more than 1900 pages of great reading!ANGELS IN THE JETS, by Jerome BixbyA CODE FOR SAM, by Lester del ReySTAR SHIP, by Poul AndersonTHE WELL-OILED MACHINE, by H.B.

The Quantum World: The disturbing theory at the heart of reality (New Scientist Instant Expert)


New Scientist - 2017
    Things can exist in two places at once and travel backwards and forwards in time. Waves and particles are one and the same, and objects change their behaviour according to whether they are being watched. This is not some alternative universe but the realm of the very small, where quantum mechanics rules. In this weird world of atoms and their constituents, our common sense understanding of reality breaks down - yet quantum mechanics has never failed an experimental test. What does it all mean? For all its weirdness, quantum mechanics has given us many practical technologies including lasers and the transistors that underlie computers and all digital technology. In the future, it promises computers more powerful than any built before, the ability to communicate with absolute privacy, and even quantum teleportation. The Quantum World explores the past, present and future of quantum science, its applications and mind-bending implications. Discover how ideas from quantum mechanics are percolating out into the vast scale of the cosmos - perhaps, in the future, to reveal a new understanding of the big bang and the nature of space and time.ABOUT THE SERIESNew Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds. Designed for curious readers who want to know how things work and why, the Instant Expert series explores the topics that really matter and their impact on individuals, society, and the planet, translating the scientific complexities around us into language that's open to everyone, and putting new ideas and discoveries into perspective and context.

Human Caused Global Warming


Tim Ball - 2016
    It explains how it was a premeditated, orchestrated deception, using science to impose a political agenda. It fooled a majority including most scientists. They assumed that other scientists would not produce science for a political agenda. German Physicist and meteorologist Klaus-Eckart Puls finally decided to look for himself. Here is what he discovered. Ten years ago I simply parroted what the IPCC told us. One day I started checking the facts and data—first I started with a sense of doubt but then I became outraged when I discovered that much of what the IPCC and the media were telling us was sheer nonsense and was not even supported by any scientific facts and measurements. To this day I still feel shame that as a scientist I made presentations of their science without first checking it.…scientifically it is sheer absurdity to think we can get a nice climate by turning a CO2 adjustment knob. This book uses the same approach used in investigative journalism. It examines the Who, What, Where, When, Why, and How.

Gravitation and Cosmology: Principles and Applications of the General Theory of Relativity


Steven Weinberg - 1972

The Search for Exoplanets: What Astronomers Know


Joshua N. Winn - 2015
    Thanks to advances in technology and clever new uses of existing data, now we know that planetary systems and possibly even a new Earth can be found throughout galaxies near and far.We are living during a new golden age of planetary discovery, with the prospect of finding many worlds like Earth. Most of the thousands of planets we've detected can't be imaged directly, but researchers are able to use subtle clues obtained in ingenious ways to assemble an astonishing picture of planetary systems far different from our own. We are in the midst of an astronomical revolution, comparable to the Copernican revolution that established our current view of the solar system - and we invite you to take part.Embark on this unrivaled adventure in 24 lectures by a veteran planet hunter. Designed for everyone from armchair explorers to serious skywatchers, The Search for Exoplanets follows the numerous twists and turns in the hunt for exoplanets - the false starts, the sudden breakthroughs, and the extraordinary discoveries. Explore systems containing super-Earths, mini-Neptunes, lava worlds, and even stranger worlds. You also get behind-the-scenes information on the techniques astronomers used to find evidence of planets at mind-boggling distances from our home base. Learn how astronomers determine how many planets are in a system as well as how large they are and the characteristics of their atmospheres. You will feel like Dr. Watson in the presence of Sherlock Holmes as Professor Winn extracts a wealth of information from a spectrum, a light graph, a diffraction pattern, and other subtle clues.©2015 The Teaching Company, LLC (P)2015 The Great Courses

What is time? What is space? (I Dialoghi)


Carlo Rovelli - 2004
    Time and space as we know them will disappear from the scientific picture of the world, in the same way in which the centre of the universe did”. In this agile text, derived from a long interview, Carlo Rovelli, theoretical physicist and pioneer of modern quantum gravity, describes his personal and intellectual journey, starting from the rebellion of his young years and the discovery of the “enchanting adventure” of theoretical research, till the vertiginous hypotheses of today’s physics. In a simple language, Rovelli introduces us to a “space” made of grains, a “time” which is the result of our ignorance, to hot black holes and how to think about the beginning of the universe. But he also discusses the value, the risks, and the fascination of this quest. Science, for Rovelli, is a continuous exploration of new ways of thinking the world, the desire of looking “beyond the hill” and seeing the world always with new eyes, the choice of never giving up dreams.

A First Course in General Relativity


Bernard F. Schutz - 1985
    This textbook, based on the author's own undergraduate teaching, develops general relativity and its associated mathematics from a minimum of prerequisites, leading to a physical understanding of the theory in some depth. It reinforces this understanding by making a detailed study of the theory's most important applications - neutron stars, black holes, gravitational waves, and cosmology - using the most up-to-date astronomical developments. The book is suitable for a one-year course for beginning graduate students or for undergraduates in physics who have studied special relativity, vector calculus, and electrostatics. Graduate students should be able to use the book selectively for half-year courses.

Dark Matter


S.W. Ahmed - 2008
    But what if it actually is nothing more than ordinary matter purposely hidden from our view? What if we are only allowed to see a small fraction of the stars in our galaxy, because the vast majority of star systems are teeming with aliens who wish to remain unseen? Marc Zemin, a brilliant student of astrophysics, is the first human to ever stumble upon this startling secret, when his experiments with wormhole travel cause aliens to land on Earth and whisk him away into space. To his astonishment, the aliens want his help in fighting a colossal galactic war that is rapidly spiraling out of control. But as he struggles to survive from battle to battle across the farthest reaches of the galaxy, he begins to uncover a horrifying conspiracy at play, striving to keep the warring civilizations in continuous conflict with each other. A desperate race against time ensues, as he and a handful of newfound alien friends try to stop the war and confront this mysterious, powerful force bent on destroying all life in the galaxy. But any hope of their success surprisingly appears to hinge on just one thing - whether or not Marc has the strength to overcome his own demons and face the shattering truth about who he really is. "A sci-fi debut that shows great potential." - Kirkus Discoveries

Black Holes & Time Warps: Einstein's Outrageous Legacy


Kip S. Thorne - 1994
    In this masterfully written and brilliantly informed work of scientific history and explanation, Dr. Thorne, the Feynman Professor of Theoretical Physics at Caltech, leads his readers through an elegant, always human, tapestry of interlocking themes, coming finally to a uniquely informed answer to the great question: what principles control our universe and why do physicists think they know the things they think they know? Stephen Hawking's A Brief History of Time has been one of the greatest best-sellers in publishing history. Anyone who struggled with that book will find here a more slowly paced but equally mind-stretching experience, with the added fascination of a rich historical and human component.

Decoding Reality: The Universe as Quantum Information


Vlatko Vedral - 2010
    The Universe and its workings are the ebb and flow of information. We are all transient patterns of information, passing on the recipe for our basic forms to future generations using a four-letter digital code called DNA.In this engaging and mind-stretching account, Vlatko Vedral considers some of the deepest questions about the Universe and considers the implications of interpreting it in terms of information. He explains the nature of information, the idea of entropy, and the roots of this thinking in thermodynamics. He describes the bizarre effects of quantum behaviour - effects such as 'entanglement', which Einstein called 'spooky action at a distance' and explores cutting edge work on the harnessing quantum effects in hyperfast quantum computers, and how recent evidence suggests that the weirdness of the quantum world, once thought limited to the tiniest scales, may reach into the macro world.Vedral finishes by considering the answer to the ultimate question: where did all of the information in the Universe come from? The answers he considers are exhilarating, drawing upon the work of distinguished physicist John Wheeler. The ideas challenge our concept of the nature of particles, of time, of determinism, and of reality itself.

Extreme Cosmos: A Guided Tour of the Fastest, Brightest, Hottest, Heaviest,Oldest, and Most Amazing Aspects of Our Universe
