We live in exciting times. the frontiers of physics have been pushed to unprecedented horizons. the Holy Grail of fundamental physics research today is to find and describe a theory that explains, at least in principle, all physical phenomena, which in turns explains chemistry, biology and other material sciences. This, however, is not without controversy. the current candidate for such a theory is known as string or superstring theory. It suffers from the problem of being a purely mathematical science with no experimental backing and belief in it has been criticized as bordering on "faith" as opposed to scientific scrutiny. On the other hand the recent switching-on of our most advanced experimental tool, the Large Hadron Collider in Switzerland, gives new hope in our search for clues as to what the universe is made of on a fundamental level. What happened exactly on, or even before, the Big Bang? Where are we coming from and where are we going? Questions that have never been addressed before by physicists. the game is afoot and the search is on. This book contains articles by leading physicists describing the current situation. Among them are proponents as well as opponents of string theory, proponents of other ideas, and experimentalists.

"In Search of a Theory of Everything is an adventurous journey in space and time in search of a unified "theory of everything" (TOE) by means of a rare and agile interplay between the natural philosophies of influential ancient Greek thinkers and the laws of modern physics. For a TOE, all the phenomena of nature share a subtle underlying commonality and are explainable by a single overarching immutable principle. Reading the past for what it is, is of tremendous value, but so is its reading from the perspective of modern knowledge. Not to judge it for its flaws but to be inspired by its insights. This comparative study of the universe is the spirit of In Search of a Theory of Everything-to physics through philosophy, to the new via the old, and in a balanced way. A relatively "easier" analysis of nature, that of a major natural philosopher of antiquity, commences every chapter to fasten the bedrock for the more complex. The transition into the more complicated views of modern physics is gradual and systematic, entwining finely the two, the ancient with the new, the forgotten with the current, by unfolding a history and a philosophy of science, and connecting all the great feats of the mind and time. Those philosophers had ideas that resonate with aspects of modern science; puzzles that still baffle; and rationales that can be used to reassess completely anew fundamental but competing principles of modern physics, even to speculate about open physics problems. In Search of a Theory of Everything is a new kind of sight, is a philosophical insight of modern physics"--

Stephen W. Hawking, widely believed to have been one of be one of the world’s greatest minds, presents a series of seven lectures— covering everything from big bang to black holes to string theory—. These lectures not only capture the brilliance of Hawking’'s mind, but his characteristic wit as well. In The Illustrated Theory of Everything, Hawking begins with a history of ideas about the universe, from Aristotle’s determination that the Earth is round to Hubble’s discovery, more than 2,000 years later, that the universe is expanding. Using that as a launching pad, he explores the reaches of modern physics, including theories on the origin of the universe (e.g., the Big Bang), the nature of black holes, and space-time. Finally, he poses the questions left unanswered by modern physics, especially how to combine all the partial theories into a “unified theory of everything.” “If we find the answer to that,” he claims, “it would be the ultimate triumph of human reason.” A great popularizer of science as well as a brilliant scientist, Hawking believes that advances in theoretical science should be “understandable in broad principle by everyone, not just a few scientists.” In this book, he offers a fascinating voyage of discovery about the cosmos and our place in it. It is a book for anyone who has ever gazed at the night sky and wondered what was up there and how it came to be.

"A pleasure. ... Suitable for beach reading or for mainlining before a dinner party." —Dan Piepenbring, New York Times Book Review (Editors' Choice) "Absorbing. ... As thoughtfully written as it is nuts." —Chicago Tribune A collection of the world’s most mind-boggling, thought-provoking, and downright hilarious theories by the co-host of the hit podcast No Such Thing as a Fish, Dan Schreiber. Why are we here? Do ghosts exist? Will we ever travel back in time? Are we being visited by extraterrestrials? Will we ever talk to animals? Are we being told the truth? Are mysterious creatures roaming the Earth? And why, when you’re in the shower, does the shower curtain always billow in towards you? We don’t know the answers to any of these questions (that includes the shower-curtain one, which is a mystery that has eluded scientists for decades, and which they are still trying to solve). But don’t worry, no matter what questions you have, you can bet on the fact that there is someone (or something) out there, investigating it on your behalf—and Dan Schreiber collects their latest findings. From the Silicon Valley tech billionaires currently trying to work out whether or not the universe is one giant video game simulation to the self-proclaimed community of Italian time-travelers who are trying to save the world from destruction; The Theory of Everything Else will act as a handbook for those who want to think differently.

Just because everyone else thinks you should be over it, doesn’t mean you are Last year, Sarah’s best friend, Jamie, died in a freak accident. Back then, everyone was sad; now they’re just ready for Sarah to get over it and move on. But Sarah’s not ready. She can’t stop reliving what happened, struggling with guilt, questioning the meaning of life, and missing her best friend. Her grades are plummeting, her relationships are falling apart, and her normal voice seems to have been replaced with a snark box. Life just seems random: no pattern, no meaning, no rules—and no reason to bother. In a last-ditch effort to pull it together, Sarah befriends Jamie’s twin brother, Emmett, who may be the only other person who understands what she’s lost. And when she gets a job working for the local eccentric who owns a Christmas tree farm, she finally begins to understand the threads that connect us all, the benefit of giving people a chance, and the power of love.

Covariant Physics: From Classical Mechanics to General Relativity and Beyond endeavours to provide undergraduate students as well as self-learners with training in the fundamentals of the modern theories of spacetime, most notably the general theory of relativity as well as physics in curved spacetime backgrounds in general. This text does so with the barest of mathematical preparation. In fact, very little beyond multivariable calculus and a bit of linear algebra is assumed. Throughout this textbook, the main theme tying the various topics is the so-called principle of covariance - a fundamental symmetry of physics that one rarely encounters in undergraduate texts. The material is introduced very gradually, starting with the simplest of high school mathematics, and moving through the more intense notions of tensor calculus, geometry, and differential forms with ease. Familiar notions from classical mechanics and electrodynamics are used to increase familiarity with the advanced mathematical ideas, and to emphasize the unity of all of physics under the single principle of covariance. The mathematical and physical techniques developed in this book should allow students to perform research in various fields of theoretical physics as early as their sophomore year in college. The language the reader will learn in this book is the foundational mathematical language of many modern branches of physics, and as such should allow them to read and generally understand many modern physics papers.

What can Mary Wollstonecraft teach Christians about sexual ethics? Can John Stuart Mill help the church understand toleration? Are there lessons for the Christian world from writers like Marx, Nehru, Shelley, Popper, and Hume? Atheism for Christians looks at the work of some of the most influential secular thinkers and asks what Christians can learn without giving up their faith or core values. Looking at important modern issues such as gender equality, same-sex marriage, creationism and evolution, abortion, universal health, biblical literalism, and religious tribalism, this work offers a fresh perspective on old questions. The Bible says the value of wisdom is far above rubies. It should not matter where that wisdom comes from. The Christian world should be able to celebrate and learn from the intellectual giants in the secular tradition just as atheists can still appreciate the great academic and artistic contribution of Christianity. The nexus between faith and reason is sometimes stretched but should never be abandoned. Atheism for Christians offers a unique insight into the work of some of the greatest secular thinkers and argues there is much to learn.
