This book explores the rise of theoretical physics in 19th century Germany. The authors show how the junior second physicist in German universities over time became the theoretical physicist, of equal standing to the experimental physicist. Gustav Kirchhoff, Hermann von Helmholtz, and Max Planck are among the great German theoretical physicists whose work and career are examined in this book. Physics was then the only natural science in which theoretical work developed into a major teaching and research specialty in its own right. Readers will discover how German physicists arrived at a well-defined field of theoretical physics with well understood and generally accepted goals and needs. The authors explain the nature of the work of theoretical physics with many examples, taking care always to locate the research within the workplace. The book is a revised and shortened version of Intellectual Mastery of Nature: Theoretical Physics from Ohm to Einstein, a two-volume work by the same authors. This new edition represents a reformulation of the larger work. It retains what is most important in the original work, while including new material, sharpening discussions, and making the research more accessible to readers. It presents a thorough examination of a seminal era in physics.

*Shortlisted for the 2019 Royal Society Insight Investment Science Book Prize* One of the most fascinating scientific detective stories of the last fifty years, an exciting quest for a new form of matter. “A riveting tale of derring-do” (Nature), this book reads like James Gleick’s Chaos combined with an Indiana Jones adventure. When leading Princeton physicist Paul Steinhardt began working in the 1980s, scientists thought they knew all the conceivable forms of matter. The Second Kind of Impossible is the story of Steinhardt’s thirty-five-year-long quest to challenge conventional wisdom. It begins with a curious geometric pattern that inspires two theoretical physicists to propose a radically new type of matter—one that raises the possibility of new materials with never before seen properties, but that violates laws set in stone for centuries. Steinhardt dubs this new form of matter “quasicrystal.” The rest of the scientific community calls it simply impossible. The Second Kind of Impossible captures Steinhardt’s scientific odyssey as it unfolds over decades, first to prove viability, and then to pursue his wildest conjecture—that nature made quasicrystals long before humans discovered them. Along the way, his team encounters clandestine collectors, corrupt scientists, secret diaries, international smugglers, and KGB agents. Their quest culminates in a daring expedition to a distant corner of the Earth, in pursuit of tiny fragments of a meteorite forged at the birth of the solar system. Steinhardt’s discoveries chart a new direction in science. They not only change our ideas about patterns and matter, but also reveal new truths about the processes that shaped our solar system. The underlying science is important, simple, and beautiful—and Steinhardt’s firsthand account is “packed with discovery, disappointment, exhilaration, and persistence...This book is a front-row seat to history as it is made” (Nature).

Here is a lively history of modern physics, as seen through the lives of thirty men and women from the pantheon of physics. William H. Cropper vividly portrays the life and accomplishments of such giants as Galileo and Isaac Newton, Marie Curie and Ernest Rutherford, Albert Einstein and Niels Bohr, right up to contemporary figures such as Richard Feynman, Murray Gell-Mann, and Stephen Hawking. We meet scientists--all geniuses--who could be gregarious, aloof, unpretentious, friendly, dogged, imperious, generous to colleagues or contentious rivals. As Cropper captures their personalities, he also offers vivid portraits of their great moments of discovery, their bitter feuds, their relations with family and friends, their religious beliefs and education. In addition, Cropper has grouped these biographies by discipline--mechanics, thermodynamics, particle physics, and others--each section beginning with a historical overview. Thus in the section on quantum mechanics, readers can see how the work of Max Planck influenced Niels Bohr, and how Bohr in turn influenced Werner Heisenberg. Our understanding of the physical world has increased dramatically in the last four centuries. With Great Physicists, readers can retrace the footsteps of the men and women who led the way.

In this biography of Enrico Fermi (1901-54), who won the Nobel Prize in physics in 1938 for his work on radioactivity by neutron bombardment and his discovery of transuranic elements and who achieved the first controlled nuclear chain reaction in Chicago in 1942, his student, collaborator, fellow Nobel Prize winner and lifelong friend Emilio Segrè presents the scientist, and explains in nontechnical terms Fermi’s work and his achievements. “Segrè’s description of Fermi’s early life and his involvement with and commitment to physics is extremely interesting... Segrè understands and describes very clearly the outstanding characteristics of Fermi’s theoretical work: clarity and completeness... Segrè has succeeded admirably in describing Fermi’s entire scientific career, and this book is strongly recommended.” — M. L. Goldberger, Science “We must thank Emilio Segrè for this authoritative, revealing and inspiring book. It covers in a masterly fashion the most exciting thirty years of modern physics and the character and activities of one of its greatest contributors.” — Nature “A rich, well-rounded portrait of [Fermi] the scientist, his methods, intellectual history, and achievements. Explaining in nontechnical terms the scientific problems Fermi faced or solved, Enrico Fermi, Physicist contains illuminating material concerning Fermi’s youth in Italy and the development of his scientific style.” — Physics Today “All that might be hoped for in a biography of one Nobel Prize winner in physics by another has been realized in Emilio Segrè’s biography of his friend, Enrico Fermi... A truly masterly drawing of Fermi’s character, along with his physics and the events through which he moved, Segrè has provided us with a brilliant appreciation of one of the most pre-eminent figures of modern physics.” — Physics Bulletin “This excellent biography, written by one of the original group who worked with him during the 1930s at Rome, catches beautifully the style and spirit of its subject... With Fermi’s passing the age of the universal experimental and theoretical physicist is gone. Segre’s book tells the story of this heroic age of physics and of its principal actor; it is a delight to read, and I recommend it heartily.” — American Scientist “Here we meet the man at work and we see the meticulous scientist... This book also shows us another facet of Fermi: that of the conscientious scientist torn between his love of pure research and his love of teaching.” — V. Barocas, Annals of Science “Segrè is a sensitive biographer, responsive to all problems that can plague the creative scientist; he shows, above all, Fermi’s dedication, zeal, and extraordinary talents. Segrè has provided more than sympathy. Much that is new about Fermi’s youth in Italy appears here... [A] very rewarding book... Every physicist will want to read this biography, along with every reader who has an interest in intellectual developments during the 1920-1960 era.” — J. Z. Fullmer, The Ohio Journal of Science

For physics students interested in the mathematics they use, and for math students interested in seeing how some of the ideas of their discipline find realization in an applied setting. The presentation strikes a balance between formalism and application, between abstract and concrete. The interconnections among the various topics are clarified both by the use of vector spaces as a central unifying theme, recurring throughout the book, and by putting ideas into their historical context. Enough of the essential formalism is included to make the presentation self-contained.

One of TIME’s Ten Best Nonfiction Books of the Decade "Meet the new Stephen Hawking . . . The Order of Time is a dazzling book." --The Sunday Times From the bestselling author of Seven Brief Lessons on Physics, Reality Is Not What It Seems, Helgoland, and Anaximander comes a concise, elegant exploration of time. Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most readers this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it remains. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where at the most fundamental level time disappears. He explains how the theory of quantum gravity attempts to understand and give meaning to the resulting extreme landscape of this timeless world. Weaving together ideas from philosophy, science and literature, he suggests that our perception of the flow of time depends on our perspective, better understood starting from the structure of our brain and emotions than from the physical universe. Already a bestseller in Italy, and written with the poetic vitality that made Seven Brief Lessons on Physics so appealing, The Order of Time offers a profoundly intelligent, culturally rich, novel appreciation of the mysteries of time.

The compelling story of leading physicists in Germany—including Peter Debye, Max Planck, and Werner Heisenberg—and how they accommodated themselves to working within the Nazi state in the 1930s and ’40s. After World War II, most scientists in Germany maintained that they had been apolitical or actively resisted the Nazi regime, but the true story is much more complicated. In Serving the Reich, Philip Ball takes a fresh look at that controversial history, contrasting the career of Peter Debye, director of the Kaiser Wilhelm Institute for Physics in Berlin, with those of two other leading physicists in Germany during the Third Reich: Max Planck, the elder statesman of physics after whom Germany’s premier scientific society is now named, and Werner Heisenberg, who succeeded Debye as director of the institute when it became focused on the development of nuclear power and weapons. Mixing history, science, and biography, Ball’s gripping exploration of the lives of scientists under Nazism offers a powerful portrait of moral choice and personal responsibility, as scientists navigated “the grey zone between complicity and resistance.” Ball’s account of the different choices these three men and their colleagues made shows how there can be no clear-cut answers or judgment of their conduct. Yet, despite these ambiguities, Ball makes it undeniable that the German scientific establishment as a whole mounted no serious resistance to the Nazis, and in many ways acted as a willing instrument of the state. Serving the Reich considers what this problematic history can tell us about the relationship between science and politics today. Ultimately, Ball argues, a determination to present science as an abstract inquiry into nature that is “above politics” can leave science and scientists dangerously compromised and vulnerable to political manipulation.

The explosive debate that transformed our views about time and scientific truth On April 6, 1922, in Paris, Albert Einstein and Henri Bergson publicly debated the nature of time. Einstein considered Bergson's theory of time to be a soft, psychological notion, irreconcilable with the quantitative realities of physics. Bergson, who gained fame as a philosopher by arguing that time should not be understood exclusively through the lens of science, criticized Einstein's theory of time for being a metaphysics grafted on to science, one that ignored the intuitive aspects of time. The Physicist and the Philosopher tells the remarkable story of how this explosive debate transformed our understanding of time and drove a rift between science and the humanities that persists today. Jimena Canales introduces readers to the revolutionary ideas of Einstein and Bergson, describes how they dramatically collided in Paris, and traces how this clash of worldviews reverberated across the twentieth century. She shows how it provoked responses from figures such as Bertrand Russell and Martin Heidegger, and carried repercussions for American pragmatism, logical positivism, phenomenology, and quantum mechanics. Canales explains how the new technologies of the period—such as wristwatches, radio, and film—helped to shape people’s conceptions of time and further polarized the public debate. She also discusses how Bergson and Einstein, toward the end of their lives, each reflected on his rival’s legacy—Bergson during the Nazi occupation of Paris and Einstein in the context of the first hydrogen bomb explosion. The Physicist and the Philosopher is a magisterial and revealing account that shows how scientific truth was placed on trial in a divided century marked by a new sense of time.
