Understanding Physics provides a thorough grounding in contemporary physics while placing physics into its social and historical context. Based in large part on the highly respected Project Physics Course developed by two of the authors, it also integrates the results of recent pedagogical research. The text thus: - teaches about the basic phenomena in the physical world and the concepts developed to explain them - shows that science is a rational human endeavor with a long and continuing tradition, involving many different cultures and people - develops facility in critical thinking, reasoned argumentation, evaluation of evidence, mathematical modeling, and ethical values The treatment emphasizes not only what we know but also how we know it, why we believe it, and what effects that knowledge has: - Why do we believe the Earth and planets revolve around the Sun? - Why do we believe that matter is made of atoms? - How do relativity theory and quantum mechanics alter our conception of Nature and in what ways do they leave the classical concepts unchanged? - What impact does the knowledge of finite energy resources have on our society?- How have applications of fundamental science (such as the steam engine, the laser, the electric generator, the transistor) affected our lives? - How does the evidence for non-scientific ideas, such as UFOs, ESP, and the like, differ from the evidence for accepted scientific results?

As the twentieth century drew to a close, computers, the Internet, and nanotechnology were central to modern American life. Yet the advances in physics underlying these applications are poorly understood and widely underappreciated by U.S. citizens today. In this concise overview, David C. Cassidy sharpens our perspective on modern physics by viewing this foundational science through the lens of America's engagement with the political events of a tumultuous century.American physics first stirred in the 1890s-around the time x-rays and radioactivity were discovered in Germany-with the founding of graduate schools on the German model. Yet American research lagged behind the great European laboratories until highly effective domestic policies, together with the exodus of physicists from fascist countries, brought the nation into the first ranks of world research in the 1930s. The creation of the atomic bomb and radar during World War II ensured lavish government support for particle physics, along with computation, solid-state physics, and military communication. These advances facilitated space exploration and led to the global expansion of the Internet.Well into the 1960s, physicists bolstered the United States' international status, and the nation repaid the favor through massive outlays of federal, military, and philanthropic funding. But gradually America relinquished its postwar commitment to scientific leadership, and the nation found itself struggling to maintain a competitive edge in science education and research. Today, American physicists, relying primarily on industrial funding, must compete with smaller, scrappier nations intent on writing their own brief history of physics in the twenty-first century.

Volume 1 presents important new material on the young Einstein. Over half the documents made available here were discovered by the editors, including a significant group of over fifty letters that Einstein exchanged with Mileva Maric, his fellow student and future wife. These letters, together with other previously unpublished documents, provide an entirely new view of Einstein's youth. The documents in the volume also foreshadow the emergence of his extraordinary creative power. In them is manifested his intense commitment to scientific work and his interest in certain themes that proved to be central to his thinking during the next decade. We can follow, for example, the beginnings of his preoccupation with the electrodynamics of moving bodies that was to lead to the development of this special theory of relativity. For the first time it can be seen how closely he followed such contemporary developments in physics as Planck's work on radiation theory and Drude's work on the electron theory of metals.In addition to all of Einstein's known correspondence and other writings from this period, the volume includes the relevant portions of all third-party letters and other contemporary documents that provide additional information about his secondary schooling at the Aargau Cantonal School; his four years at the Swiss Federal Plytechnical School, or the ETH; and his search for a job after graduation. Included in the volume are those sections of an unpublished biography by Einstein's sister, Maja Winteler-Einstein, which deal with his early years; his extensive notes on a physics course he took at the ETH; and previously unpublished photographs of the young Einstein and his teachers and friends. Documents in Volume 1 portray Einstein's experiences during the two stressful years after his graduation from the ETH in Zurich. Denied a position as an Assistant at the ETH, he lived a hand-to-mouth existence while he looked for a post at other universities; then he attempted to find a secondary-school post, and finally sought a nonacademic job. Tension with his parents over his plans to marry Mileva Maric is evident throughout this period.With the help of a friend, he finally found work at the Swiss Patent Office, the haven where he would spend the next seven years. Freed from his financial worries, he entered on one of the most productive periods of his life, as the next volume, Writings (1901-1910), will document.

This volume of The Collected Papers of Albert Einstein contains the scientific work Einstein published during the first decade of his career, and includes some of the most significant achievements of twentieth-century physics. The first paper was written in 1900 by the twenty-one-year-old Einstein, newly graduated from the Swiss Federal Polytechnical School, or ETH, in Zurich and still searching in vain for a job. The last paper in this volume is the text of an invited lecture given in 1909 to a major scientific meeting by Einstein after he was appointed to his first academic post at the University of Zurich. He had already been recognized as an important theoretical physicist on the basis of the work reprinted here, particularly the three masterpieces that appeared in quick succession during 1905, Einstein's year of miracles. In one of these papers Einstein showed how one could finally confirm the ancient view that matter is composed of discrete atoms, and even measure the numbers and masses of these atoms.In a second paper, which even he referred to as "very revolutionary," he argued that the observed properties of thermal radiation suggest that it consists not of waves, but rather of localized particles of energy which he called energy quanta. The third and most famous paper set forth the special theory of relativity, solving some long-standing difficulties, but requiring a significant change in our understanding of those basic concepts, space and time.

David C. Cassidy's celebrated biography is more than the life story of J. Robert Oppenheimer, the brilliant physicist who served as scientific director for the Manhattan Project. It also tells the hidden story of the political and social forces that shaped the world in the 20th century, when the rise of American science contributed mightily to the country's emergence as a dominant power in world affairs. Cassidy explores that strong relationship in the captivating story of the rise and fall of one of America's greatest scientists. As head of the Manhattan Project, Oppenheimer led the country's successful effort to build the first atom bomb during World War II. In 1954 the government-with the United States embroiled in the Cold War-stripped him of his security clearance amid allegations that he consorted with communists. In rich detail Cassidy places this personal story of public disgrace within the larger narrative of the rise of science in America.

"A fascinating, well-documented biography." --New York Times Book Review "A monumental effort." --New York Review of Books "An excellent piece of science writing...Cassidy does not so much exculpate Heisenberg as explain him, with a transparency that makes this biography a pleasure to read." --Los Angeles Times "Cassidy has written the definitive biography of a great and tragic physicist." --Richard Rhodes, author of the Pulitzer Prize--winning The Making of the Atomic Bomb Since the fall of the Soviet Union, long-suppressed information has emerged on Werner Heisenberg's role in the Nazi atomic bomb project. In Beyond Uncertainty, Cassidy interprets this and other previously unknown material within the context of his vast research and tackles the vexing questions of a scientist's personal responsibility and guilt when serving an abhorrent military regime. David C. Cassidy is the author of Beyond Uncertainty: Heisenberg, Quantum Physics, and the Bomb; A Short History of Physics in the American Century; J. Robert Oppenheimer and the American Century; and Einstein and Our World.He is the recipient of the Abraham Pais Prize for History of Physics from the American Physical Society, the Science Writing Award from the American Institute of Physics, the Pfizer Award from the History of Science Society, and an honorary doctorate from Purdue University. Dr. Cassidy is Professor of Natural Sciences at Hofstra University and resides in Bay Shore, New York.
