Space is the venue of physics; it's where things exist, where they move and take shape. Yet over the past few decades, physicists have discovered a phenomenon that operates outside the confines of space and time: nonlocality-the ability of two particles to act in harmony no matter how far apart they may be. It appears to be almost magical. Einstein grappled with this oddity and couldn't come to terms with it, describing it as "spooky action at a distance." More recently, the mystery has deepened as other forms of nonlocality have been uncovered. This strange occurrence, which has direct connections to black holes, particle collisions, and even the workings of gravity, holds the potential to undermine our most basic understandings of physical reality. If space isn't what we thought it was, then what is it? In Spooky Action at a Distance, George Musser sets out to answer that question, offering a provocative exploration of nonlocality and a celebration of the scientists who are trying to explain it. Musser guides us on an epic journey into the lives of experimental physicists observing particles acting in tandem, astronomers finding galaxies that look statistically identical, and cosmologists hoping to unravel the paradoxes surrounding the big bang. He traces the often contentious debates over nonlocality through major discoveries and disruptions of the twentieth century and shows how scientists faced with the same undisputed experimental evidence develop wildly different explanations for that evidence. Their conclusions challenge our understanding of not only space and time but also the origins of the universe-and they suggest a new grand unified theory of physics. Delightfully readable, Spooky Action at a Distance is a mind-bending voyage to the frontiers of modern physics that will change the way we think about reality.Long-listed for the 2016 PEN/E. O. Wilson Literary Science Writing Award“An important book that provides insight into key new developments in our understanding of the nature of space, time and the universe.

    He provides readers with non-trivial insights into research fields they may not have encountered previously . . . I think everyone who has ever considered the possibility that other intelligent civilizations exist elsewhere within our galaxy will enjoy Where Is Everybody? They will find much to agree with, and much to argue about, in this very accessible volume.� �SCIENCE During a Los Alamos lunchtime conversation that took place more than 50 years ago, four world-class scientists agreed, given the size and age of the Universe, that advanced extraterrestrial civilizations simply had to exist. The sheer numbers demanded it. But one of the four, the renowned physicist and back-of-the-envelope calculator Enrico Fermi, asked the telling question: If the extraterrestrial life proposition is true, he wondered, "Where IS everybody?" In this lively and thought-provoking book, Stephen Webb presents a detailed discussion of the 50 most cogent and intriguing answers to Fermi's famous question, divided into three distinct groups: - Aliens are already here among us. Here are answers ranging from Leo Szilard's suggestion that they are already here, and we know them as Hungarians, to the theorists who claim that aliens built Stonehenge and the Easter Island statues. - Aliens exist, but have not yet communicated. The theories in this camp range widely, from those who believe we simply don't have the technologies to receive their signals, to those who believe the enormities of space and time work against communication, to those who believe they're hiding from us. - Aliens do not exist. Here are the doubters' arguments, from the Rare Earth theory to the author's own closely argued and cogently stated skepticism. The proposed solutions run the gamut from the crackpot to the highly serious, but all deserve our consideration. The varieties of arguments -- from first-rate scientists, philosophers and historians, and science fiction authors -- turn out to be astonishing, entertaining, and vigorous intellectual exercises for any reader interested in science and the sheer pleasure of speculative thinking. Stephen Webb is a physicist working at the Open University in England and the author of Measuring the Universe.

    The issues Professor Dalton addresses in these lectures - and in Western political theory generally - fall into three sets of fundamental questions you'll get to unpack. The first set involves the essential characteristics of human nature and the good society. The second focuses on the intricate relationship between the individual and society. And the final set of questions involves theories about change.Through these lectures and their historical case studies, you'll be able to identify the fundamental questions and concerns that shape classical and modern political theory:Describe the influence of one's understanding of human nature upon one's vision of the good society.Compare and contrast the views of theorists regarding the purpose of the state, the relationship between politics and ethics, and the qualifications for exercising political power.Discuss views of leading political theorists regarding the meaning of freedom, the sources of legitimate political authority, and the obligations of individuals to the state or society, and more.

    Now you can learn the basics of jazz and its history in a course as free-flowing and original as jazz itself. Taught by Professor Bill Messenger of the Peabody Institute, the lectures in this course are a must for music lovers. They will have you reaching deep into your own music collection and going straight out to a music store to add to it. Professor Messenger has spent his life in music as student, teacher, and professional musician. He has studied and lectured at the famed Peabody Institute and written an acclaimed book on music activities aimed at older adults. And as a pianist, he has: Played in ragtime ensembles, swing bands, Dixieland bands, and modern jazz groups Been a successful studio musician in the early days of rock 'n' roll Accompanied performers as renowned as Lou Rawls and Mama Cass Elliot Opened for Bill Haley and the Comets. So it is no wonder that the course he has created is so thorough and enjoyable. Lectures, Piano, and Guest Performers It's a rich mix of jazz, its elements, era, and practitioners. Professor Messenger frequently turns to his piano to illustrate his musical points, often with the help of guest performance artists and lots of original music. The lectures follow the story of jazz in its many shapes, including: Ragtime The blues The swing music of the big band era Boogie-woogie Big band blues The rise of modern jazz forms: bebop, cool, modal, free, and fusion. Cakewalks, Vaudeville, and Swing Beginning with the music and dance of the antebellum plantation, Professor Messenger reveals how the "cakewalks" of slave culture gave birth to a dance craze at the 19th century's end that was ignorant of its own humble roots. He considers how minstrel shows, deriving from Southern beliefs that held black culture to be decidedly inferior, eventually created a musical industry that African American musicians would dominate for decades to come. You will learn how and why jazz, a difficult genre to define, was central to the music they created. Roots in Ragtime Professor Messenger explains how jazz was born-or conceived-in the ragtime piano tunes of turn-of-the-century America. Together with the Dixieland funeral music of New Orleans, this new, "syncopated" music popularized a sound that took America's vaudeville establishments by storm. Professor Messenger notes that ragtime's most popular composer, Scott Joplin, at first resisted the new craze. But after becoming intrigued by that "ragged" sound at the Chicago World's Fair of 1893, he became the writer of the most memorable rags ever, including "Maple Leaf Rag" and "The Entertainer." Drawing on the blues, an emotional but harmonically simple music, jazz was ensconced as a popular genre in the American psyche by the 1920s. The Surprising Origin of the "St. Louis Blues" One interesting story about the blues covered in the course concerns W. C. Handy, a man often referred to as the "father of the blues." As Professor Messenger reveals that, in truth, Handy didn't like the blues very much and wasn't convinced the public would buy it. It was only after he saw a band of blues players literally showered with money after a performance that he began writing the music in earnest. Handy was at the same World's Fair Joplin attended, and he heard a song he later arranged into what became the famous "St. Louis Blues." Professor Messenger points out, nothing about the song was original; it was a melting pot of many influences. The blues is, in his words, the "emotional germ of jazz." It is the place jazz always returns to when it veers too far into the abstract or academic. An Innovation that Changed Jazz Forever One of the most important events in the history of jazz, and all performance, was the invention of the microphone in 1924. Before the microphone, singers needed big voices to project their voices across large music halls, and the booming styles of performers such as Bessie Smith and Al Jolson met those requirements admirably. After the microphone, though, things were very different. The new invention did more than simply allow for the use of quieter instruments like the guitar and string bass. It also brought smaller-voiced singers-Bing Crosby, Mel Torme, Frank Sinatra, for instance-into the limelight. Into the 1930s and 40s, popular music became heavily arranged for bigger and bigger bands. By the time the swing era of America's big bands took hold around World War II, jazz had reached new popular heights. You will learn why swing became so popular-the syncopation and improvisation of early jazz, in the context of careful arrangements, combined planning and spontaneity in a unique way. Though not to be confused with the sound of competing society bands, swing music gave talents like Benny Goodman a chance to improvise within the framework of Top 40 hits.More than Swing The development of jazz into swing electrified popular music. You learn: How boogie-woogie, a precursor of rock 'n' roll that was primed with a heavy-handed, highly rhythmic style, found widespread success in the 1940s until its ubiquity forced it out of fashion How big band blues, where the simplicity of the blues standard was overlaid on the pop song, fused the worlds of folk art and high art How bebop-an austere, anxious music whose success was blazed by the genius of Dizzy Gillespie and Charlie Parker-worked against the commercial spread of swing How modern jazz spans everything-from the cool jazz of the 1950s to the fusion jazz of the 1990s, with several stops in between. Music for Today In recent decades many forms of modern jazz-including cool, modal, free, and fusion-have had their devoted following. All serve to prove that jazz is a generic music that comprises many varieties. True to its name, jazz has defied definition, category, and stagnation. And this course-in toe-tapping, finger-snapping ways-will feed your intellectual curiosity and appreciation.

    This ancient civilization prospered in the region of modern-day Tuscany, maintaining extensive trade networks, building impressive fortified cities, making exquisite art, and creating a culture that, while deeply connected to the Greeks and Romans, had striking contrasts.

    A project of CERN, the European Organization for Nuclear Research, its audacious purpose is to re-create, in a 16.5-mile-long circular tunnel under the French-Swiss countryside, the immensely hot and dense conditions that existed some 13.7 billion years ago within the first trillionth of a second after the fiery birth of our universe. The collider is now crashing protons at record energy levels never created by scientists before, and it will reach even higher levels by 2013. Its superconducting magnets guide two beams of protons in opposite directions around the track. After accelerating the beams to 99.9999991 percent of the speed of light, it collides the protons head-on, annihilating them in a flash of energy sufficient—in accordance with Einstein’s elegant statement of mass-energy equivalence, E=mc2—to coalesce into a shower of particles and phenomena that have not existed since the first moments of creation. Within the LHC’s detectors, scientists hope to see empirical confirmation of key theories in physics and cosmology.In telling the story of what is perhaps the most anticipated experiment in the history of science, Amir D. Aczel takes us inside the control rooms at CERN at key moments when an international team of top researchers begins to discover whether this multibillion-euro investment will fulfill its spectacular promise. Through the eyes and words of the men and women who conceived and built CERN and the LHC—and with the same clarity and depth of knowledge he demonstrated in the bestselling Fermat’s Last Theorem—Aczel enriches all of us with a firm grounding in the scientific concepts we will need to appreciate the discoveries that will almost certainly spring forth when the full power of this great machine is finally unleashed.Will the Higgs boson make its breathlessly awaited appearance, confirming at last the Standard Model of particles and their interactions that is among the great theoretical achievements of twentieth-century physics? Will the hidden dimensions posited by string theory be revealed? Will we at last identify the nature of the dark matter that makes up more than 90 percent of the cosmos? With Present at the Creation, written by one of today’s finest popular interpreters of basic science, we can all follow the progress of an experiment that promises to greatly satisfy the curiosity of anyone who ever concurred with Einstein when he said, “I want to know God’s thoughts—the rest is details.”

    It was the first force to be recognized and described yet it is the least understood. It is a "force" that keeps your feet on the ground yet no such force actually exists.Gravity, to steal the words of Winston Churchill, is "a riddle, wrapped in a mystery, inside an enigma." And penetrating that enigma promises to answer the biggest questions in science: what is space? What is time? What is the universe? And where did it all come from?Award-winning writer Marcus Chown takes us on an unforgettable journey from the recognition of the "force" of gravity in 1666 to the discovery of gravitational waves in 2015. And, as we stand on the brink of a seismic revolution in our worldview, he brings us up to speed on the greatest challenge ever to confront physics.

    The media seized hold of the story and, in the process, helped to launch one of the most devastating health scares ever. In the years to come Wakefield would be revealed as a profiteer in league with class-action lawyers, and he would eventually lose his medical license. Meanwhile, one study after another failed to find any link between childhood vaccines and autism. Yet the myth that vaccines somehow cause developmental disorders lives on. Despite the lack of corroborating evidence, it has been popularized by media personalities such as Oprah Winfrey and Jenny McCarthy and legitimized by journalists who claim that they are just being fair to “both sides” of an issue about which there is little debate. Meanwhile, millions of dollars have been diverted from potential breakthroughs in autism research; families have spent their savings on ineffective “miracle cures"; and declining vaccination rates have led to outbreaks of deadly illnesses like Hib, measles, and whooping cough. Most tragic of all is the increasing number of children dying from vaccine-preventable diseases. In The Panic Virus Seth Mnookin draws on interviews with parents, public-health advocates, scientists, and anti-vaccine activists to tackle a fundamental question: How do we decide what the truth is? The fascinating answer helps explain everything from the persistence of conspiracy theories about 9/11 to the appeal of talk-show hosts who demand that President Obama “prove” he was born in America. The Panic Virus is the ultimate cautionary tale for our time.
