Wigners symetries and reflections essay

He had an older sister, Bertha, known as Biri, and a younger sister Margit, known as Manci, [2] who later married British theoretical physicist Paul Dirac. During this period, Wigner developed an interest in mathematical problems. His parents sent him to live for six weeks in a sanatorium in the Austrian mountains, before the doctors concluded that the diagnosis was mistaken. Religious education was compulsory, and he attended classes in Judaism taught by a rabbi.

Wigner, Nobel laureate in physics in at an age of sixty-one and recipient of several other scientific awards, has not only written for the specialist, but expressed himself on matters of physics and issues of general concern to the non-specialist.

Twenty-four of his articles, addresses and lectures have, more recently, been reprinted in one volume: The rest require quite some knowledge of physics for a fuller appreciation.

The reprinted papers, with the exception of one which appeared inwere originally published during the period from to Half of them were published in or after The volume contains papers on the nature of physical symmetries, invariance and conservation principles; on the compound nucleus model and nuclear chain reactions; on the structure of, and the effects of radiation on, solids.

Several articles deal with the problem of measurement in quantum mechanics and other more philosophical issues raised by quantum mechanics. Some more general papers are on the prospects of nuclear energy, on the first man-made chain reaction, and on nuclear disarma- ment.

Also of a general nature are those on the growth and limits of science and the role of mathematics in the natural sciences. II Wigner, inwas the first to apply group theory to the then newly developed quantum mechanics in an explicit way, and he has made major contributions to that and cognate fields of physics ever since.

Although he received the Nobel prize intogether with M. Jensen, for his work in nuclear physics, it was widely felt by physicists that his introduction of group-theoretical methods into quantum physics had also found its due, if 1 Unless otherwise indicated all page references will be to the volume reviewed.

Printed in Great Britain. The conceptual means and mathematical techniques provided by group theory are most appropriate in dealing with symmetries and invariance pro- perties of physical systems and of space and time.

Symmetries, for instance those of the regular solids, have for a long time attracted the attention of inquiring men. The same is true of invariance properties, like the very intuitive ones of homogeneity and isotropy of space.

Attention was focused on the laws of nature; principles of invariance could, as a by-product, be obtained from the laws. Proceeding this way, H. He also recognized that these transformations formed a group which he named after H.

Einstein who, in his special theory of relativity, postulated their general validity. As Wigner also notes,4 conservation laws were intuitively recognized even before Galileo. The laws of conservation of energy and momentum became an integral part of classical physics.The ideas of Wigner are being actively pursued by today's scientists.
