Book Description
Energy can be neither created nor destroyed—but it can be wasted. The United States wastes two-thirds of its energy, including 80 percent of the energy used in transportation. So the nation has a tremendous opportunity to develop a sensible energy policy based on benefits and costs. But to do that we need facts—not hyperbole, not wishful thinking. Mara Prentiss presents and interprets political and technical information from government reports and press releases, as well as fundamental scientific laws, to advance a bold claim: wind and solar power could generate 100 percent of the United States’ average total energy demand for the foreseeable future, even without waste reduction. To meet the actual rather than the average demand, significant technological and political hurdles must be overcome. Still, a U.S. energy economy based entirely on wind, solar, hydroelectricity, and biofuels is within reach. The transition to renewables will benefit from new technologies that decrease energy consumption without lifestyle sacrifices, including energy optimization from interconnected smart devices and waste reduction from use of LED lights, regenerative brakes, and electric cars. Many countries cannot obtain sufficient renewable energy within their borders, Prentiss notes, but U.S. conversion to a 100 percent renewable energy economy would, by itself, significantly reduce the global impact of fossil fuel consumption. Enhanced by full-color visualizations of key concepts and data, Energy Revolution answers one of the century’s most crucial questions: How can we get smarter about producing and distributing, using and conserving, energy?

Book Description
In 1900 many eminent scientists did not believe atoms existed, yet within just a few years the atomic century launched into history with an astonishing string of breakthroughs in physics that began with Albert Einstein and continues to this day. Before this explosive growth into the modern age took place, an all-but-forgotten genius strove for forty years to win acceptance for the atomic theory of matter and an altogether new way of doing physics. Ludwig Boltz-mann battled with philosophers, the scientific establishment, and his own potent demons. His victory led the way to the greatest scientific achievements of the twentieth century. Now acclaimed science writer David Lindley portrays the dramatic story of Boltzmann and his embrace of the atom, while providing a window on the civilized world that gave birth to our scientific era. Boltzmann emerges as an endearingly quixotic character, passionately inspired by Beethoven, who muddled through the practical matters of life in a European gilded age. Boltzmann's story reaches from fin de siècle Vienna, across Germany and Britain, to America. As the Habsburg Empire was crumbling, Germany's intellectual might was growing; Edinburgh in Scotland was one of the most intellectually fertile places on earth; and, in America, brilliant independent minds were beginning to draw on the best ideas of the bureaucratized old world. Boltzmann's nemesis in the field of theoretical physics at home in Austria was Ernst Mach, noted today in the term Mach I, the speed of sound. Mach believed physics should address only that which could be directly observed. How could we know that frisky atoms jiggling about corresponded to heat if we couldn't see them? Why should we bother with theories that only told us what would probably happen, rather than making an absolute prediction? Mach and Boltzmann both believed in the power of science, but their approaches to physics could not have been more opposed. Boltzmann sought to explain the real world, and cast aside any philosophical criteria. Mach, along with many nineteenth-century scientists, wanted to construct an empirical edifice of absolute truths that obeyed strict philosophical rules. Boltzmann did not get on well with authority in any form, and he did his best work at arm's length from it. When at the end of his career he engaged with the philosophical authorities in the Viennese academy, the results were personally disastrous and tragic. Yet Boltzmann's enduring legacy lives on in the new physics and technology of our wired world. Lindley's elegant telling of this tale combines the detailed breadth of the best history, the beauty of theoretical physics, and the psychological insight belonging to the finest of novels.

Book Description
Change in scientific practice and its implications for the status of scientific claims, examined through an analysis of three episodes at a synchrotron laboratory. After World War II, particle physics became a dominant research discipline in American academia. At many universities, alumni of the Manhattan Project and of Los Alamos were granted resources to start (or strengthen) programs of high-energy physics built around the promise of a new and more powerful particle accelerator, the synchrotron. The synchrotron was also a source of very intense X-rays, useful for research in solid states physics and in biology. As synchrotron X-ray science grew, the experimental practice of protein crystallography (used to determine the atomic structures of proteins and viruses), garnered funding, prestige, and acclaim. In Velvet Revolution at the Synchrotron, Park Doing examines the change in scientific practice at a synchrotron laboratory as biology rose to dominance over physics. He draws on his own observations and experiences at the Cornell University synchrotron, and considers the implications of that change for the status of scientific claims. Velvet Revolution at the Synchrotron is one of the few recent works in the sociology of science that engages specific scientific and technical claims through participant observation—recorded evocatively and engagingly—to address issues in the philosophy of science. Doing argues that bureaucratic change in science is neither “top-down” nor “bottom-up” but rather performed in and realized through recursively related forums of technical assertion and resistance. He considers the relationship of this change to the content of science, and the implications of this relationship for the project of laboratory studies begun in the late 1970s.

Book Description
Richard Feynman once quipped that "Time is what happens when nothing else does." But Julian Barbour disagrees: if nothing happened, if nothing changed, then time would stop. For time is nothing but change. It is change that we perceive occurring all around us, not time. Put simply, time does not exist. In this highly provocative volume, Barbour presents the basic evidence for a timeless universe, and shows why we still experience the world as intensely temporal. It is a book that strikes at the heart of modern physics. It casts doubt on Einstein's greatest contribution, the spacetime continuum, but also points to the solution of one of the great paradoxes of modern science, the chasm between classical and quantum physics. Indeed, Barbour argues that the holy grail of physicists--the unification of Einstein's general relativity with quantum mechanics--may well spell the end of time. Barbour writes with remarkable clarity as he ranges from the ancient philosophers Heraclitus and Parmenides, through the giants of science Galileo, Newton, and Einstein, to the work of the contemporary physicists John Wheeler, Roger Penrose, and Steven Hawking. Along the way he treats us to enticing glimpses of some of the mysteries of the universe, and presents intriguing ideas about multiple worlds, time travel, immortality, and, above all, the illusion of motion. The End of Time is a vibrantly written and revolutionary book. It turns our understanding of reality inside-out.

Book Description
A daring new vision of quantum theory from one of the leading minds of contemporary physics Quantum physics is the golden child of modern science. It is the basis of our understanding of atoms, radiation, and so much else, from elementary particles and basic forces to the behavior of materials. But for a century it has also been the problem child of science: it has been plagued by intense disagreements between its inventors, strange paradoxes, and implications that seem like the stuff of fantasy. Whether it's Schrödinger's cat--a creature that is simultaneously dead and alive--or a belief that the world does not exist independently of our observations of it, quantum theory challenges our fundamental assumptions about reality. In Einstein's Unfinished Revolution, theoretical physicist Lee Smolin provocatively argues that the problems which have bedeviled quantum physics since its inception are unsolved and unsolvable, for the simple reason that the theory is incomplete. There is more to quantum physics, waiting to be discovered. Our task--if we are to have simple answers to our simple questions about the universe we live in--must be to go beyond quantum mechanics to a description of the world on an atomic scale that makes sense. In this vibrant and accessible book, Smolin takes us on a journey through the basics of quantum physics, introducing the stories of the experiments and figures that have transformed our understanding of the universe, before wrestling with the puzzles and conundrums that the quantum world presents. Along the way, he illuminates the existing theories that might solve these problems, guiding us towards a vision of the quantum that embraces common sense realism. If we are to have any hope of completing the revolution that Einstein began nearly a century ago, we must go beyond quantum mechanics to find a theory that will give us a complete description of nature. In Einstein's Unfinished Revolution, Lee Smolin brings us a step closer to resolving one of the greatest scientific controversies of our age.

Book Description
Named a Best Book of 2021 by the Financial Times and a Best Science Book of 2021 by The Guardian “Rovelli is a genius and an amazing communicator… This is the place where science comes to life.” ―Neil Gaiman “One of the warmest, most elegant and most lucid interpreters to the laity of the dazzling enigmas of his discipline...[a] momentous book” ―John Banville, The Wall Street Journal A startling new look at quantum theory, from the New York Times bestselling author of Seven Brief Lessons on Physics, The Order of Time, and Anaximander. One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the twenty-three-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious. As scientists and philosophers continue to fiercely debate the meaning of the theory, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships rather than substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for thinking about the structure of reality and even the nature of consciousness. Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better comprehend our place in it.

Book Description
With a New Afterword "Our knowledge of fundamental physics contains not one fruitful idea that does not carry the name of Murray Gell-Mann."--Richard Feynman Acclaimed science writer George Johnson brings his formidable reporting skills to the first biography of Nobel Prize-winner Murray Gell-Mann, the brilliant, irascible man who revolutionized modern particle physics with his models of the quark and the Eightfold Way. Born into a Jewish immigrant family on New York's East 14th Street, Gell-Mann's prodigious talent was evident from an early age--he entered Yale at 15, completed his Ph.D. at 21, and was soon identifying the structures of the world's smallest components and illuminating the elegant symmetries of the universe. Beautifully balanced in its portrayal of an extraordinary and difficult man, interpreting the concepts of advanced physics with scrupulous clarity and simplicity, Strange Beauty is a tour-de-force of both science writing and biography.
