    Drawing from years of teaching modern physics to nonscientists, Wolfson explains in a lively, conversational style the simple principles underlying Einstein's theory.Relativity, Wolfson shows, gave us a new view of space and time, opening the door to questions about their flexible nature: Is the universe finite or infinite? Will it expand forever or eventually collapse in a "big crunch"? Is time travel possible? What goes on inside a black hole? How does gravity really work? These questions at the forefront of twenty-first-century physics are all rooted in the profound and sweeping vision of Albert Einstein's early twentieth-century theory. Wolfson leads his readers on an intellectual journey that culminates in a universe made almost unimaginably rich by the principles that Einstein first discovered.

    We are introduced to the known particles of the world we live in. An elegant explanation of quantum mechanics and relativity paves the way for an understanding of the laws that govern particle physics. These laws are put into action in the world of accelerators, colliders and detectors found at institutions such as CERN and Fermilab that are in the forefront of technical innovation. Real world and theory meet using Feynman diagrams to solve the problems of infinities and deduce the need for the Higgs boson.Facts and Mysteries in Elementary Particle Physics offers an incredible insight from an eyewitness and participant in some of the greatest discoveries in 20th century science. From Einstein's theory of relativity to the elusive Higgs particle, this book will fascinate and educate anyone interested in the world of quarks, leptons and gauge theories.This book also contains many thumbnail sketches of particle physics personalities, including contemporaries as seen through the eyes of the author. Illustrated with pictures, these candid sketches present rare, perceptive views of the characters that populate the field.The Chapter on Particle Theory, in a pre-publication, was termed “superbly lucid” by David Miller in Nature (Vol. 396, 17 Dec. 1998, p. 642).

    Provides a review of introductory noncalculus-based physics for those who do not have a strong background in mathematics.

    They found him a dreamy child without an especially promising future. But some time in his early years he developed what he called wonder about the world. Later in life, he remembered two instances from his childhood--his fascination at age five with a compass and his introduction to the lucidity and certainty of geometry--that may have been the first signs of what was to come. From these ordinary beginnings, Einstein became one of the greatest scientific thinkers of all time. This illuminating biography describes in understandable language the experiments and revolutionary theories that flowed from Einstein's imagination and intellect--from his theory of relativity, which changed our conception of the universe and our place in it, to his search for a unified field theory that would explain all of the forces in the universe.

    - This is the best kind of popular science: informed, impassioned, and highly accessible.- Compare it to Stephen Hawking's The Universe in a Nutshell, but broader in scope and much more readable.- A crossover for the Young Adult market, now in the perfect format.

    He never realized he was poor until, in the seventh grade, kids at school made fun of his clothing. This was a turning point for Tom. He decided that he would never be poor again and wanted a better life. Tom’s story is the quintessential rags to riches tale, a narrative that embodies the American Dream. Now it’s his turn to pass it along, to share his training methods and proven business models with you in his book, The Boxcar Millionaire. Achieve genuine sales success, find your turning point and sell more than you ever thought was possible.

    In those twelve months, Einstein shattered many cherished scientific beliefs with five extraordinary papers that would establish him as the world's leading physicist. This book brings those papers together in an accessible format. The best-known papers are the two that founded special relativity: On the Electrodynamics of Moving Bodies and Does the Inertia of a Body Depend on Its Energy Content? In the former, Einstein showed that absolute time had to be replaced by a new absolute: the speed of light. In the second, he asserted the equivalence of mass and energy, which would lead to the famous formula E = mc2.The book also includes On a Heuristic Point of View Concerning the Production and Transformation of Light, in which Einstein challenged the wave theory of light, suggesting that light could also be regarded as a collection of particles. This helped to open the door to a whole new world--that of quantum physics. For ideas in this paper, he won the Nobel Prize in 1921.The fourth paper also led to a Nobel Prize, although for another scientist, Jean Perrin. On the Movement of Small Particles Suspended in Stationary Liquids Required by the Molecular-Kinetic Theory of Heat concerns the Brownian motion of such particles. With profound insight, Einstein blended ideas from kinetic theory and classical hydrodynamics to derive an equation for the mean free path of such particles as a function of the time, which Perrin confirmed experimentally. The fifth paper, A New Determination of Molecular Dimensions, was Einstein's doctoral dissertation, and remains among his most cited articles. It shows how to calculate Avogadro's number and the size of molecules.These papers, presented in a modern English translation, are essential reading for any physicist, mathematician, or astrophysicist. Far more than just a collection of scientific articles, this book presents work that is among the high points of human achievement and marks a watershed in the history of science. Coinciding with the 100th anniversary of the miraculous year, this new paperback edition includes an introduction by John Stachel, which focuses on the personal aspects of Einstein's youth that facilitated and led up to the miraculous year.

    He decried the internment of Japanese-Americans in World War Two, agitated against nuclear weapons, promoted vitamin C as a cure for the common cold and researched the idea of DNA.

    In addition, it discusses antennas and microwave techniques at a technician level and covers data communication techniques (modems, local area networks, fiber optics, satellite communication) and advanced applications (cellular telephones, facsimile and radar). The work is suitable for courses in Communications Technology.

    The space-age sounding title was suggested over 800 years ago by "The Blind Ones and the Elephant," a story immortalized in Rumi's Mathnavi.

    Over the next ten years the “Strange” books sold over 6,000,000 copies worldwide. Strange True Encounters & Unearthly Experiences is the first new book in the series in over three decades, and features: Robert M. Schoch, Ph.D. in Geology and Geophysics at Yale University on discoveries at Anatolia‘s Gobekli Tepe suggesting civilization is far older than previously believed. Gregory Sams on unfolding evidence that stars may be conscious. Janet Brennan on Europe’s mysterious Black Madonna statues. Martin Cadin, ex-member Federal Aviation Administration, on his personal experiments using telekinesis. Michio Kaku, Professor of Theoretical Physics at the City University of New York, on our ten-dimensional universe and paranormal phenomenon. Journalist Chris Friar on 19th century UFO sightings proving they are not a modern phenomenon. Actor Anthony Quinn on the “profound mystical experience” in the Sinai Desert that changed his life. Plus over a dozen other accounts, investigation and in-depth reports on the Ouija board, remote viewing, poltergeists, Kansas’ sacred sites, the U.S. warship that was saved by an angel, and much more. We believe this brand new entry in the “Strange” series – is in every way the equal of its predecessors. And will prove every bit as entertaining and enlightening as the earlier books did. (Asked where he got the ideas for his stories, Steven King credited FATE. “My mother used to read me FATE Magazine, which was about the paranormal, flying saucers…all that stuff. I was fascinated.”) Here is what Amazon readers have to say about classic reprints from FATE: “A book worth reading. I look forward to reading the other books in this series.” “FATE always comes through.” “Well written, short articles on a variety of paranormal events, many of which were unfamiliar to me. Interesting, unfamiliar and competently edited.” “Good stuff. Reminds us that stories like this have been happening for years. Not just a modern invention. Worth a read.” “Very good read. 5 stars.”

    Second, it proposes that the inhabitants of this subterranean biosphere are not plants or animals as we know them, but heat-loving bacteria that survive on a diet consisting solely of hydrocarbons that is, natural gas and petroleum. And third and perhaps most heretically, the book advances the stunning idea that most hydrocarbons on Earth are not the byproduct of biological debris ("fossil fuels"), but were a common constituent of the materials from which the earth itself was formed some 4.5 billion years ago.The implications are astounding. The theory proposes answers to often-asked questions: Is the deep hot biosphere where life originated, and do Mars and other seemingly barren planets contain deep biospheres? Even more provocatively, is it possible that there is an enormous store of hydrocarbons upwelling from deep within the earth that can provide us with abundant supplies of gas and petroleum?However far-fetched these ideas seem, they are supported by a growing body of evidence, and by the indisputable stature and seriousness Gold brings to any scientific debate. In this book we see a brilliant and boldly original thinker, increasingly a rarity in modern science, as he develops potentially revolutionary ideas about how our world works.

    As Teilhard de Chardin did in The Divine Milieu, Ilia Delio reveals the sacrament of God at work in the world. She also explores the spiritual evolution within each of us and suggests that it will change the cosmos as well as the church. She shows that we are at a stage in evolution where our choices will determine what happens next. "Love," she writes, "always seeks the best for the beloved but God is a beggar of love who waits at the soul's door without daring to force it open. The question of Christ emerging as the personal center of the universe is not a question of yes or no but a question of how that love will evolve." She makes one thing perfectly clear: it is happening and the evidence is astounding.The Emergent Christ is an antidote to the new atheism that says there is no place in evolution for God, let alone a God of love. It is also a spiritual tonic for Christians interested in understanding their place and purpose in this evolving universe.
