"An elegant read for anyone interested in understanding modern physics. Tavel has a genuine knack for making the difficult and obscure clear and exciting." --Joseph C. Pitt, author of Thinking about Technology "You will never look at scientific theories in the same way again." --John Hubiscz, North Carolina State University Introductory physics is not often a popular class among liberal arts majors. With its lively prose and analogies from the arts, humanities, and social sciences, however, Contemporary Physics and the Limits of Knowledge is guaranteed to enlighten and delight nonscience majors. Morton Tavel contends that every one of the six topics that he explores--symmetry, special and general relativity, statistical physics, quantum mechanics, and chaos--has played a role in telling us what we are unable to know about the physical world. He explains what each of the topics reveals about our attempts to pinpoint reality, and how each scientific revelation forces us to acknowledge a narrowing rather than a broadening of our knowledge. Chaos theory, for example, reveals a way to understand the randomness that seems so prevalent in natural phenomena such as weather. This development unifies our understanding of many phenomena that had been previously thought unrelated. Yet, chaos represents a significant diminution in what we can hope to predict about the course of natural events. It has increased our knowledge or understanding of a phenomena, but has seriously eroded our long-held, Newtonian vision of prediction and control. Tavel emphasizes the features of physics that make it a very human endeavor and serve to build bridges to all other intellectual disciplicnes.

Walter Thirring is an internationally renowned scientist who took part in and worked among those involved in many of the scientific developments of the twentieth century. His book, about the knowledge of the world as illuminated by twentieth century science, was originally published in German. This is the first English translation and is a book that is easily accessible to readers of popular science books and magazines.

Professor Thirring starts with cosmology as he examines scientific questions and theories concerning the intricacy of nature and the universe. He branches into an exposition of chaos and its connection to the macroscopic world, as well as to life sciences, touching on such diverse related subjects as the structure of the water molecule. He speaks of advances with which he was personally involved, and offers priceless vignettes of great scientists with whom he exchanged discussions, including Albert Einstein, Werner Heisenberg, Erwin Schrödinger, and Wolfgang Pauli.

His study of scientific theory and the intricacy of nature and the universe illuminates his argument for the role of a Creator. "Reflections on the creation of the universe lead to reflections about the creator," he writes. And arguing against atheism, he points out:

Furthermore, in making humankind special in his creation, the Creator gave us the responsibility of seeking an understanding of creation and protecting it.

Tackling complex issues in science and religion, Professor Thirring presents a compelling argument for their synthesis. His tenure and influence in the scientific field make this argument even more compelling.

For millennia humans have studied the skies to help them grow crops, navigate the seas, and earn favor from their gods. We still look to the stars today for answers to fundamental questions: How did the universe begin? Will it end, and if so, how? What is our place within it? John North has been examining such questions for decades. In Cosmos, he offers a sweeping historical survey of the two sciences that help define our place in the universe: astronomy and cosmology.
            Organizing his history chronologically, North begins by examining Paleolithic cave drawings that clearly chart the phases of the moon. He then investigates scientific practices in the early civilizations of Egypt, Greece, China, and the Americas (among others), whose inhabitants developed sophisticated methods to record the movements of the planets and stars. Trade routes and religious movements, North notes, brought these ancient styles of scientific thinking to the attention of later astronomers, whose own theories—such as Copernicus’ planetary theory—led to the Scientific Revolution.
            The work of master astronomers, including Ptolemy, Galileo, Kepler, and Newton, is described in detail, as are modern-day developments in astrophysics, such as the advent of radio astronomy, the brilliant innovations of Einstein, and the many recent discoveries brought about with the help of the Hubble telescope. This new edition brings North’s seminal book right up to the present day, as North takes a closer look at last year’s reclassification of Pluto as a “dwarf” planet and gives a thorough overview of current research.
            With more than two hundred illustrations and a comprehensive bibliography, Cosmos is the definitive history of astronomy and cosmology. It is sure to find an eager audience among historians of science and astronomers alike.

Albert Einstein’s theory of general relativity describes the effect of gravitation on the shape of space and the flow of time. But for more than four decades after its publication, the theory remained largely a curiosity for scientists; however accurate it seemed, Einstein’s mathematical code—represented by six interlocking equations—was one of the most difficult to crack in all of science. That is, until a twenty-nine-year-old Cambridge graduate solved the great riddle in 1963. Roy Kerr’s solution emerged coincidentally with the discovery of black holes that same year and provided fertile testing ground—at long last—for general relativity. Today, scientists routinely cite the Kerr solution, but even among specialists, few know the story of how Kerr cracked Einstein’s code.

Fulvio Melia here offers an eyewitness account of the events leading up to Kerr’s great discovery. Cracking the Einstein Code vividly describes how luminaries such as Karl Schwarzschild, David Hilbert, and Emmy Noether set the stage for the Kerr solution; how Kerr came to make his breakthrough; and how scientists such as Roger Penrose, Kip Thorne, and Stephen Hawking used the accomplishment to refine and expand modern astronomy and physics. Today more than 300 million supermassive black holes are suspected of anchoring their host galaxies across the cosmos, and the Kerr solution is what astronomers and astrophysicists use to describe much of their behavior.

By unmasking the history behind the search for a real world solution to Einstein’s field equations, Melia offers a first-hand account of an important but untold story. Sometimes dramatic, often exhilarating, but always attuned to the human element, Cracking the Einstein Code is ultimately a showcase of how important science gets done.
