A Nobel prize winner, a great man and a great scientist, Erwin
Schroedinger has made his mark in physics, but his eye scans a far
wider horizon: here are two stimulating and discursive essays which
summarize his philosophical views on the nature of the world.
Schroedinger's world view, derived from the Indian writings of the
Vedanta, is that there is only a single consciousness of which we
are all different aspects. He admits that this view is mystical and
metaphysical and incapable of logical deduction. But he also
insists that this is true of the belief in an external world
capable of influencing the mind and of being influenced by it.
Schroedinger's world view leads naturally to a philosophy of
reverence for life.
Reprint of a classical book first published in 1950. This lucid and profound exposition of Einstein's 1915 theory of gravitation is essential reading.
Nobel laureate Erwin Schroedinger was one of the most distinguished
scientists of the twentieth century; his lectures on the history
and philosophy of science are legendary. 'Nature and the Greeks'
and 'Science and Humanism' makes available for the first time in
many years the texts of two of Schroedinger's most famous lecture
series. 'Nature and the Greeks' offers a comprehensive historical
account of the twentieth-century scientific world picture, tracing
modern science back to the earliest stages of Western philosophic
thought. 'Science and Humanism' addresses some of the most
fundamental questions of the century: what is the value of
scientific research? And how do the achievements of modern science
affect the relationship between material and spiritual matters? A
foreword by Roger Penrose sets the lectures in a contemporary
context, and affirms they are as relevant today as when they were
first published.
Quantum Theory, together with the principles of special and general relativity, constitute a scientific revolution that has profoundly influenced the way in which we think about the universe and the fundamental forces that govern it. The Historical Development of Quantum Theory is a definitive historical study of that scientific work and the human struggles that accompanied it from the beginning. Drawing upon such materials as the resources of the Archives for the History of Quantum Physics, the Niels Bohr Archives, and the archives and scientific correspondence of the principal quantum physicists, as well as Jagdish Mehra's personal discussions over many years with most of the architects of quantum theory, the authors have written a rigorous scientific history of quantum theory in a deeply human context. This multivolume work presents a rich account of an intellectual triumph: a unique analysis of the creative scientific process. The Historical Development of Quantum Theory is science, history, and biography, all wrapped in the story of a great human enterprise. Its lessons will be an aid to those working in the sciences and humanities alike.
Wir werden spater, aus guten Grunden, der einen den Vorzug geben,
im Augenblick mussen wir uns mit beiden auseinander- etzen. Die
altere und naivere Anwendung bezieht sich auf N wirklich
existierende physikalische Systeme, die in wirklicher
physikalischer Wechselwirkung miteinander stehen, also z. B.
Gasmolekule oder Elektronen oder Plancksche Oszillatoren oder
Freiheitsgrade (AtherosziIlatoren) eines "Hohlraumes". Aile N
zusammen stellen das betrachtete wirkliche physikalische System
dar. Dieser ursprungliche Gesichtspunkt ist an die Namen von
MAXWELL, BOLTZMANN und anderen geknupft. Er genugt aber nur zur
Behandlung einer sehr beschriinkten Klasse von physikalischen
Systemen - in der Tat nur der Gase. Er ist nicht auf ein System
anwendbar, das nicht aus einer groBen Anzahl identischer
Bestandteile mit "privaten" Ener- gien zusammengesetzt ist. In
einem festen Korper ist die Wech- selwirkung zwischen Nachbaratomen
so stark, daB man auch nicht gedanklich seine Gesamtenergie in die
Privatenergien seiner Atome aufteilen kann, ja schon ein "Hohlraum"
(ein "Atherblock" als Sitz der Vorgange im elektromagnetischen
Felde) laBt sich nur in OsziIlatoren von vielen - unendlich vie-
len - verschiedenen Arten auflosen, so daB es mindestens not- wen
dig ware, mit einer Gesamtheit von unendlich vielen ver- schiedenen
(weil aus verschiedenen Bestandteilen bestehenden) Gesamtheiten zu
arbeiten.
