Weyl was a German American mathematician who, through his widely varied contributions in mathematics, served as a link between pure mathematics and theoretical physics, in particular adding enormously to quantum mechanics and the theory of relativity. Hermann Weyl (1885-1955) was perhaps the most important and, above all, the most multifaceted of David Hilbert's students. His life's work encompassed such varied disciplines as number theory,...

From the Preface: "The name of Hermann Weyl is enshrined in the history of mathematics. A thinker of exceptional depth, and a creator of ideas, Weyl possessed an intellect which ranged far and wide over the realm of mathematics, and beyond. His mind was sharp and quick, his vision clear and penetrating. Whatever he touched he adorned. His personality was suffused with humanity and compassion, and a keen aesthetic sensibility. Its fullness radiated charm. He was young at heart to the end. By precept and example, he inspired many mathematicians, and influenced their lives. The force of his...

"A classic of physics ... the first systematic presentation of Einstein's theory of relativity." -- "British Journal for Philosophy and Science. Long one of the standard texts in the field, this excellent introduction probes deeply into Euclidean space, Riemann's space, Einstein's general relativity, gravitational waves and energy, and laws of conservation.

2014 Reprint of 1934 Edition. Full facsimile of the original edition. Not reproduced with Optical Recognition Software. Hermann Weyl (1885-1955) was one of the twentieth centurys 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. The lectures printed in this volume were delivered in the autumn of 1933. In this book the author presents a veritable pageant...
