Solutions to the 25th & 26th International Young Physicists' Tournament provides original, quantitative solutions in fulfilling seemingly impossible tasks. The book expands on the solutions required by the problems. Many of the articles include modification, extension to existing models in references, or derivation and computation based on fundamental physics, and are not confined to the models and methods in present literatures. The International Young Physicists' Tournament (IYPT) is one of the most prestigious international physics contests among high school students. This book is based on the solutions of 2012 and 2013 IYPT problems. The young authors provide quantitative solutions to practical problems in everyday life, such as the 2013 problem “Bouncing ball” that shows “how the nature of the collision changes if the ball contains liquid”, “Colored plastic” (2013 problem 6) and “Helmholtz carousel” (2013 problem 12) etc. This book is intended as a college-level solutions guide to the challenging open-ended problems. It is a good reference book for undergraduates, advanced high-school students, physics educators and the curious public interested in the intriguing phenomenon encountered in daily life.

The book originated in a series of lectures given at Liverpool in 2013 to a group that included postgraduate and undergraduate students and staff of the Physics Department. They followed from two very successful lectures given to the undergraduate Physical Society. It seemed that there was a very large interest among the students in investigating the foundations of physics in a way that was never done in physics courses, and was not available in books or other outlets. However, the idea was to create a framework in which students (and interested staff) could develop their own thinking relative to the ideas in the lectures. So it was important to create both conceptual and mathematical structures on the issues that are important at this level. The book has the right sort of technical content to allow for this development, but doesn't lose itself in excessive details. The ideal use for this book would be on postgraduate courses where students would be encouraged to think about the foundations in a way that is well beyond the superficial. However, a course on aspects of this material would also be valuable at the undergraduate level, where students could be stimulated into believing that creative thinking could solve the problems that emerge when we confront foundational problems.

A book for nonbelievers who embrace the reality-driven life. We can't avoid the persistent questions about the meaning of life-and the nature of reality. Philosopher Alex Rosenberg maintains that science is the only thing that can really answer them—all of them. His bracing and ultimately upbeat book takes physics seriously as the complete description of reality and accepts all its consequences. He shows how physics makes Darwinian natural selection the only way life can emerge, and how that deprives nature of purpose, and human action of meaning, while it exposes conscious illusions such as free will and the self. The science that makes us nonbelievers provides the insight into the real difference between right and wrong, the nature of the mind, even the direction of human history. The Atheist's Guide to Reality draws powerful implications for the ethical and political issues that roil contemporary life. The result is nice nihilism, a surprisingly sanguine perspective atheists can happily embrace.

Robert F Christy was a legendary physicist, one of the key players in some of the most dramatic events of the 20th century. He was a student of Oppenheimer, who called him “one of the best in the world.” He was a crucial member of Fermi's team when they first unleashed the unheard-of energies of nuclear power, creating the world's first nuclear reactor on December 2, 1942. On the Manhattan Project he was the key physicist in the successful test of the world's first atomic bomb, the “Christy Gadget”, at Alamogordo on July 16, 1945. Almost immediately he turned his talents to promoting the peaceful uses of atomic energy. He successfully opposed atmospheric testing of atomic bombs and fought nuclear proliferation, a campaign that eventually led to the SALT talks with the Soviet Union. His favorite subject was astrophysics where he made fundamental contributions to the understanding of Cepheids, variable stars that are crucial distance indicators in the universe. Robert was equally fascinating as a man. In his mid-50's he became irresistably attracted to an astrophysicist, but they were a continent and a generation apart. Near his 60's they started a happy and fulfilling life together. He remained vigorous both mentally and physically into his 90's: he was still galloping his horse at age 93. Robert's story is one of overcoming obstacles, of hope, and of fulfillment.

It is a fitting tribute to Robert Christy, whom I admired as a man as well as a scientist." Kip S Thorne The Feynman Professor of Theoretical Physics Emeritus California Institute of Technology (Caltech) "From the atom bomb to the frontiers of astrophysics, Bob Christy's contributions were brilliant and seminal. In an intimate account rich with personal detail, we see up close a man of enormous energy, grace, and wisdom." H David Politzer Caltech Nobel Prize in Physics 2004 "Bob Christy was an exemplary research scientist, teacher and university administrator at Caltech, playing an important role in the development of the atomic bomb and in the efforts after World War II to assure that nuclear weapons would not be used again. This informative biographical memoir by his widow reveals the warmer side of his personality, remembered by his friends but hidden from public view by his austere and analytic manner."; Harold Brown President of Caltech 1969–1977 US Secretary of Defense 1977–1981 "The deeper you get into this book, the more fascinating it becomes. Christy lived the problems of the 20th century which are defining many of the problems of the 21st." Rose Bethe widow of Hans Bethe Nobel Prize in Physics 1967 "An accomplished scientist in her own right, I-Juliana Christy has written a richly-detailed biography. Drawing on unpublished letters and interviews, she weaves together the political drama of World War II with the personal story of Christy." Judith R Goodstein Founding Head of Caltech Archives and author of Millikan's School "Juliana Christy has created a remarkable blend of historical biography and personal memoir. She presents here for the first time unique source material from Robert Christy's personal papers, along with interviews, photographs and other documentation, much of it newly published. The book is an intimate yet carefully weighed account of this great physicist's life and work." Charlotte E Erwin Head of Archives, Special Collections Caltech "A must-read for people interested in history and pioneering physics. Mentored by Oppenheimer, Christy transformed nuclear science from intellectual theory to explosive reality. A warm and compas-sionate man, he labored mightily against nuclear proliferation." Frank D Rubin attorney and history buff "The book is very well written; transcribed interviews with Christy and liberal use of historical artefacts. Where relevant the book also serves as a history text; the wider political context in the lead up to the Manhattan project is explored and the retrospective look at the German effort to develop nuclear weapons is a fascinating inclusion. Perhaps the most vivid historical inclusion, however, is the first hand description of Chicago Pile-1. With a little something for everyone, this is a fantastic read." Mr Mark Worrall Clinical Scientist Radiation Physics, Ninewells Hospital, Dundee “The unique strength of this remarkable memoir is the author's deep understanding of both Christy's scientific and administrative achievements coupled with his personal qualities: energy, wisdom, passion, modesty, and grace. Like Robert Christy, author Juliana Christy has truly "achieved the rare".” John R Percy Professor Emeritus University of Toronto “Oppenheimer, Fermi, Teller, Harold Brown, Hans Bethe, Richard Feynman — Robert Christy knew the greats of his era as both peer and colleague. This affectionate biography presents a complete picture of this national figure also as family man, horseman, skier and tennis player — a man who helped shape the world we inhabit. That is rare achievement in itself.” Bart Paul author of the novel "Under Tower Peak" and of "Double-Edged Sword: the Many Lives of Hemingway's Friend, the American Matador Sidney Franklin" “Those interested in academic administration in general or Caltech in particular will find additional fascinating sections, but the scientific and practical history of the atomic age stand alone in this worthwhile book, with book science and personal history well told.” Jay M Pansachoff Professor Williams College “It's the story of a boy from British Columbia who was a prewar student of Oppenheimer's at Berkeley, then became sucked into the Manhattan project where, at Los Alamos, he solved the problems that had confounded his colleagues, and changed the course of history.” Charles Campbell Professor University of Southern California “Author Juliana Christy is herself an astrophysicist, so she get the physics right. At the same time she brings out Robert's human side and family life in this well-rounded account with the aid of letters, photographs, interviews, and personal reminiscences.” Steven C Frautschi Professor Emeritus California Institute of Technology

This book is a sequel to the volume of selected papers of Dyson up to 1990 that was published by the American Mathematical Society in 1996. The present edition comprises a collection of the most interesting writings of Freeman Dyson, all personally selected by the author, from the period 1990–2014. The five sections start off with an Introduction, followed by Talks about Science, Memoirs, Politics and History, and some Technical Papers. The most noteworthy is a lecture entitled Birds and Frogs to the American Mathematical Society that describes two kinds of mathematicians with examples from real life. Other invaluable contributions include an important tribute to C. N. Yang written for his retirement banquet at Stony Brook University, as well as a historical account of the Operational Research at RAF Bomber Command in World War II provocatively titled A Failure of Intelligence. The final section carries the open-ended question of whether any conceivable experiment could detect single gravitons to provide direct evidence of the quantization of gravity — Is a Graviton Detectable? Various possible graviton-detectors are examined. This invaluable compilation contains unpublished lectures, and surveys many topics in science, mathematics, history and politics, in which Freeman Dyson has been so active and well respected around the world.

The twenty-first century is replete with uncertainty and complexity: game-changing events and trends are transforming the world beyond recognition. For the first time in human history more people live in cities than in the countryside and greater numbers suffer from obesity than from hunger. Emerging economies now represent half of the global economy and during the next few decades India will be the biggest country in terms of population, China the largest in output and the United States the richest among the major economies on a per capita income basis. Food and water shortages will likely become humankind's most important challenge. In this accessible introduction, Mauro Guillén and Emilio Ontiveros deploy the tools of economics, sociology and political science to provide an analytical perspective on both the problems and opportunities facing business in the modern world.
