The 4-Percent Universe by Richard Panek Pdf

Meet the players in the most fundamental scientific revolution since Copernicus The Facts of Matter It is one of the most disturbing aspects of our universe: only four per cent of it consists of the matter that makes up every star, planet, and every book. The rest is completely unknown. Acclaimed science writer Richard Panek tells the story of the handful of scientists who have spent the past few decades on a quest to unlock the secrets of “dark matter” and the even stranger substance called “dark energy”. These are perhaps the greatest mysteries in science,and solving them will reshape our understanding of the universe and our place in it. The stakes could not be higher. Panek’s fast-paced narrative, filled with original, in-depth reporting and intimate, behind-the-scenes details, brings this epic story to life for the very first time.

Dark Matter and Dark Energy by Brian Clegg Pdf

'Clear and compact ... It's hard to fault as a brief, easily digestible introduction to some of the biggest questions in the Universe' Giles Sparrow, BBC Four's The Sky at Night , Best astronomy and space books of 2019: 5/5 All the matter and light we can see in the universe makes up a trivial 5 per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That 'something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets. By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster. Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence. Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.

The Elephant in the Universe by Govert Schilling Pdf

A Seminary Co-op Notable Book A BBC Sky at Night Best Book “An impressively comprehensive bird’s-eye view of a research topic that is both many decades established and yet still at the very cutting edge of astronomy and physics.” —Katie Mack, Wall Street Journal “Schilling has craftily combined his lucid and accessible descriptions of science with the personal story of those unlocking the finer details of the missing mass mystery. The result is enthralling...A captivating scientific thriller.” —BBC Sky at Night “Fascinating...A thorough and sometimes troubling account of the hunt for dark matter...You will come away with a very good understanding of how the universe works. Well, our universe, anyway.” —Michael Brooks, New Scientist When you train a telescope on outer space, you can see luminous galaxies, nebulae, stars, and planets. But if you add all that together, it constitutes only 15 percent of the matter in the universe. Despite decades of research, the nature of the remaining 85 percent is unknown. We call it dark matter. Physicists have devised huge, sensitive instruments to search for dark matter, which may be unlike anything else in the cosmos—some unknown elementary particle. Yet so far dark matter has escaped every experiment. It is so elusive that some scientists are beginning to suspect there might be something wrong with our theories about gravity or with the current paradigms of cosmology. Govert Schilling interviews believers and heretics and paints a colorful picture of the history and current status of dark matter research. The Elephant in the Universe is a vivid tale of scientists puzzling their way toward the true nature of the universe.

Four Laws That Drive the Universe by Peter Atkins Pdf

The laws of thermodynamics drive everything that happens in the universe. From the sudden expansion of a cloud of gas to the cooling of hot metal, and from the unfurling of a leaf to the course of life itself - everything is directed and constrained by four simple laws. They establish fundamental concepts such as temperature and heat, and reveal the arrow of time and even the nature of energy itself. Peter Atkins' powerful and compelling introduction explains what the laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader from the Zeroth Law to the Third Law, he introduces the fascinating concept of entropy, and how it not only explains why your desk tends to get messier, but also how its unstoppable rise constitutes the engine of the universe.

How to Live Safely in a Science Fictional Universe (Enhanced Edition) by Charles Yu Pdf

This enhanced eBook includes video, audio, photographic, and linked content, as well as a bonus short story. Hear TAMMY talk. Learn the origins of Minor Universe 31. See the TM-31. Take a trip in it. Photos and illustrations appear as hyperlinked endnotes. Video and audio are embedded directly in text. *Video and audio may not play on all readers. Check your user manual for details. National Book Foundation 5 Under 35 Award winner Charles Yu delivers his debut novel, a razor-sharp, ridiculously funny, and utterly touching story of a son searching for his father . . . through quantum space–time. Minor Universe 31 is a vast story-space on the outskirts of fiction, where paradox fluctuates like the stock market, lonely sexbots beckon failed protagonists, and time travel is serious business. Every day, people get into time machines and try to do the one thing they should never do: change the past. That’s where Charles Yu, time travel technician—part counselor, part gadget repair man—steps in. He helps save people from themselves. Literally. When he’s not taking client calls or consoling his boss, Phil, who could really use an upgrade, Yu visits his mother (stuck in a one-hour cycle of time, she makes dinner over and over and over) and searches for his father, who invented time travel and then vanished. Accompanied by TAMMY, an operating system with low self-esteem, and Ed, a nonexistent but ontologically valid dog, Yu sets out, and back, and beyond, in order to find the one day where he and his father can meet in memory. He learns that the key may be found in a book he got from his future self. It’s called How to Live Safely in a Science Fictional Universe, and he’s the author. And somewhere inside it is the information that could help him—in fact it may even save his life. Wildly new and adventurous, Yu’s debut is certain to send shock waves of wonder through literary space–time.

Universe on a T-Shirt by Dan Falk Pdf

No scientific quest is as compelling as the search for the key to understand the universe—the elusive unified “Theory of Everything”—a theory so concise it could fit on a T-shirt. Lively and thought-provoking, Universe on a T-Shirt tells the fascinating story of the search for the Holy Grail of physics. Dan Falk places this intriguing story in its historical context, tracing the quest from ancient Greece to the breakthroughs of Newton, Maxwell, and Einstein, to the excitement over string theory and today’s efforts to merge quantum theory with general relativity. With as much emphasis on history as on science, Falk’s accessible approach is ideal for anyone intrigued by the advances in modern physics but still wondering what theoretical physicists are searching for, and why. Today’s physicists use sophisticated methods, but their goal—the search for simplicity—has not changed since the time of the ancient Greeks. Universe on a T-Shirt is filled with quirky personalities, brilliant minds, and bold ideas—high science and high drama. "An admirably concise and comprehensive overview of cosmology . . . [that] offers intriguing insights into the philosophic and personal outlooks motivating the scientists involved, from the ancient Greeks through Newton and Einstein . . . [and] Stephen Hawking and Ed Witten.”—Booklist

The Universe in a Nutshell by Stephen Hawking Pdf

Stephen Hawking’s phenomenal, multimillion-copy bestseller, A Brief History of Time, introduced the ideas of this brilliant theoretical physicist to readers all over the world. Now, in a major publishing event, Hawking returns with a lavishly illustrated sequel that unravels the mysteries of the major breakthroughs that have occurred in the years since the release of his acclaimed first book. The Universe in a Nutshell • Quantum mechanics • M-theory • General relativity • 11-dimensional supergravity • 10-dimensional membranes • Superstrings • P-branes • Black holes One of the most influential thinkers of our time, Stephen Hawking is an intellectual icon, known not only for the adventurousness of his ideas but for the clarity and wit with which he expresses them. In this new book Hawking takes us to the cutting edge of theoretical physics, where truth is often stranger than fiction, to explain in laymen’s terms the principles that control our universe. Like many in the community of theoretical physicists, Professor Hawking is seeking to uncover the grail of science — the elusive Theory of Everything that lies at the heart of the cosmos. In his accessible and often playful style, he guides us on his search to uncover the secrets of the universe — from supergravity to supersymmetry, from quantum theory to M-theory, from holography to duality. He takes us to the wild frontiers of science, where superstring theory and p-branes may hold the final clue to the puzzle. And he lets us behind the scenes of one of his most exciting intellectual adventures as he seeks “to combine Einstein’s General Theory of Relativity and Richard Feynman’s idea of multiple histories into one complete unified theory that will describe everything that happens in the universe.” With characteristic exuberance, Professor Hawking invites us to be fellow travelers on this extraordinary voyage through space-time. Copious four-color illustrations help clarify this journey into a surreal wonderland where particles, sheets, and strings move in eleven dimensions; where black holes evaporate and disappear, taking their secret with them; and where the original cosmic seed from which our own universe sprang was a tiny nut. The Universe in a Nutshell is essential reading for all of us who want to understand the universe in which we live. Like its companion volume, A Brief History of Time, it conveys the excitement felt within the scientific community as the secrets of the cosmos reveal themselves.

Dark Matter and Dark Energy by Sabino Matarrese,Monica Colpi,Vittorio Gorini,Ugo Moschella Pdf

This book brings together reviews from leading international authorities on the developments in the study of dark matter and dark energy, as seen from both their cosmological and particle physics side. Studying the physical and astrophysical properties of the dark components of our Universe is a crucial step towards the ultimate goal of unveiling their nature. The work developed from a doctoral school sponsored by the Italian Society of General Relativity and Gravitation. The book starts with a concise introduction to the standard cosmological model, as well as with a presentation of the theory of linear perturbations around a homogeneous and isotropic background. It covers the particle physics and cosmological aspects of dark matter and (dynamical) dark energy, including a discussion of how modified theories of gravity could provide a possible candidate for dark energy. A detailed presentation is also given of the possible ways of testing the theory in terms of cosmic microwave background, galaxy redshift surveys and weak gravitational lensing observations. Included is a chapter reviewing extensively the direct and indirect methods of detection of the hypothetical dark matter particles. Also included is a self-contained introduction to the techniques and most important results of numerical (e.g. N-body) simulations in cosmology. " This volume will be useful to researchers, PhD and graduate students in Astrophysics, Cosmology Physics and Mathematics, who are interested in cosmology, dark matter and dark energy.

At the Edge of the Universe by Shaun David Hutchinson Pdf

From the author of We Are the Ants comes “another winner” (Booklist, starred review) about a boy who believes the universe is slowly shrinking as the things he remembers are being erased from others’ memories. Tommy and Ozzie have been best friends since the second grade, and boyfriends since eighth. They spent countless days dreaming of escaping their small town—and then Tommy vanished. More accurately, he ceased to exist, erased from the minds and memories of everyone who knew him. Everyone except Ozzie. Ozzie doesn’t know how to navigate life without Tommy, and soon he suspects that something else is going on: that the universe is shrinking. When Ozzie is paired up with the reclusive and secretive Calvin for a physics project, it’s hard for him to deny the feelings developing between them, even if he still loves Tommy. But Ozzie knows there isn’t much time left to find Tommy—that once the door closes, it can’t be opened again. And he’s determined to keep it open as long as possible.
