The second volume of Frontiers in European Radiology covers two very promising techniques in diagnostic radiology, namely digital radiography and nuclear mag netic resonance imaging. Leading experts in both fields from Europe and the Unit ed States were invited to give a critical overview; digital fluoroscopy is reported on mainly by American scientists since this technique has been developed primarily in the United States, while the results of nuclear magnetic resonance imaging are pre se...

At the annual meeting of the American Association for the Advancement of Science in Washington, D.C., 27 December 1966, a symposium was held to commemorate the 50th anniversary of the death of Ernst Mach, the physicist who was vitally concerned about philosophical foundations. It was arranged by Section B on Physics, and co-sponsored by Section L on the History and Philosophy of Science, as well as by the History of Science Society. Dr. Allen W. Astin, Vice-President of the Association and...

A hopeful and controversial view of the universe and ourselves based on the principles of quantum physics, offering a way of making our lives and the world better, with a foreword by Deepak ChopraIn Infinite Potential, physical chemist Lothar Schäfer presents a stunning view of the universe as interconnected, nonmaterial, composed of a field of infinite potential, and conscious. With his own research as well as that of some of the most distinguished scient...

The Authorized Albert Einstein Archives Edition: An homage to the men and women of science, and an exposition of Einstein's place in scientific history.In this fascinating collection of articles and speeches, Albert Einstein reflects not only on the scientific method at work in his own theoretical discoveries, but also eloquently expresses a great appreciation for his scientific contemporaries and forefathers, including Johannes Kepler, Isaac Newton, James Clerk Max...

"The history is fascinating, as are the insights into the personalities of these great thinkers." —New ScientistIs there a number at the root of the universe? A primal number that everything in the world hinges on? This question exercised many great minds of the twentieth century, among them the groundbreaking physicist Wolfgang Pauli and the famous psychoanalyst Carl Jung. Their obsession with the power of certain numbers—including 137, which describes th...

It is a widely known but little considered fact that Albert Einstein and Kurt Godel were best friends for the last decade and a half of Einstein's life. The two walked home together from Princeton's Institute for Advanced Study every day; they shared ideas about physics, philosophy, politics, and the lost world of German science in which they had grown up. By 1949, Godel had produced a remarkable proof: In any universe described by the Theory of Relativity, time cannot exist . Ein...

The point, line, plane and solid objects represent the first three dimensions, but a kind of reversal of space is involved in the ascent to a fourth dimension. Steiner leads us to the brink of this new perspectiveas nearly as it can be done with words, diagrams, analogies, and examples of many kinds. In doing so, he continues his lifelong project of demonstrating that our objective, everyday thinking is the lowest rung of a ladder that reaches up to literally infinite heights. The talks in t...

The interest earned on a bank account, the arrangement of seeds in a sunflower, and the shape of the Gateway Arch in St. Louis are all intimately connected with the mysterious number e. In this informal and engaging history, Eli Maor portrays the curious characters and the elegant mathematics that lie behind the number. Designed for a reader with only a modest mathematical background, this biography brings out the central importance of e to mathematics and illuminates a g...

In considering the history of modern mathematics two questions at once arise:(1) What limitations shall be placed upon the term Mathematics?(2) What force shall be assigned to the word Modern? In other words, how shall Modern Mathematics be defined?In these pages the term Mathematics will be limited to the domain of pure science. Questions of the applications of the various branches will be considered only incidentally. Such great contributions as those of Newton in t...

At the age of eight, Karl Popper was puzzling over the idea of infinity and by fifteen was beginning to take a keen interest in his father's well-stocked library of books. Unended Quest recounts these moments and many others in the life of one of the most influential thinkers of the twentieth century, providing an indispensable account of the ideas that influenced him most. As an introduction to Popper's philosophy, Unended Quest also shines. Popper lucidly explains the c...

The philosophy of religion and the quest for spiritual truth preoccupied Albert Einstein--so much that it has been said "one might suspect he was a disguised theologian." Nevertheless, the literature on the life and work of Einstein, extensive as it is, does not provide an adequate account of his religious conception and sentiments. Only fragmentarily known, Einstein's ideas about religion have been often distorted both by atheists and by religious groups eager to claim him as one of their...

Hermann Weyl (1885-1955) was one of the twentieth century's most important mathematicians, as well as a seminal figure in the development of quantum physics and general relativity. He was also an eloquent writer with a lifelong interest in the philosophical implications of the startling new scientific developments with which he was so involved. Mind and Nature is a collection of Weyl's most important general writings on philosophy, mathematics, and physics, including pieces that h...
