In this monograph, the author presents a new approach to non-relativistic quantum mechanics. The monograph has four parts. In Part One the basic results of the theory of probability and of quantum mechanics are established. In Part Two the monadic properties of individual systems are derived from stationary state functions. In Part Three, the collectivistic properties of statistical assemblies are derived from superposed state functions. In Part Four, the experimental methods for determining various physical quantities are mentioned.

Nobel Laureate discusses quantum theory, uncertainty, wave mechanics, work of Dirac, Schroedinger, Compton, Einstein, others. "An authoritative statement of Heisenberg's views on this aspect of the quantum theory." — Nature.

Albert Einstein was one of the principal founders of the quantum and relativity theories. Until 1925, when Bose-Einstein statistics was discovered, he made great contributions to the foundations of quantum theory. However, after the discovery of quantum mechanics by Heisenberg and wave mechanics by Schrodinger, with the consequent development of the principles of uncertainty and complementarity, it would seem that Einstein's views completely changed. In his theory of the Brownian motion, Einstein had invoked the theory of probability to establish the reality of atoms and molecules; but, in 1916-17, when he wished to predict the exact instant when an atom would radiate -- and developed his theory of the A and B coefficients -- "a statistical residue remained," which he did not quite have the courage of his convictions to accept, as he told his friend Max Born. However, he wrote later to Born that quantum mechanics "is certainly imposing," but "an inner voice tells me that it is not the real thing ... It does,not bring us closer to the secret of the 'Old One'. I, at any rate, am convinced that He is not playing at dice." At the 1927 and 1930 Solvay Conferences on Physics in Brussels, Einstein engaged in profound discussions with Niels Bohr and others about his conviction regarding classical determinism versus the statistical causality of quantum mechanics. To the end of his life he retained his belief in a deterministic philosophy. This highly interesting book explores Einstein's views on the nature and structure of physics and reality.

The untold story of Albert Einstein's role as the father of quantum theory Einstein and the Quantum reveals for the first time the full significance of Albert Einstein's contributions to quantum theory. Einstein famously rejected quantum mechanics, observing that God does not play dice. But, in fact, he thought more about the nature of atoms, molecules, and the emission and absorption of light—the core of what we now know as quantum theory—than he did about relativity. A compelling blend of physics, biography, and the history of science, Einstein and the Quantum shares the untold story of how Einstein—not Max Planck or Niels Bohr—was the driving force behind early quantum theory. It paints a vivid portrait of the iconic physicist as he grappled with the apparently contradictory nature of the atomic world, in which its invisible constituents defy the categories of classical physics, behaving simultaneously as both particle and wave. And it demonstrates how Einstein's later work on the emission and absorption of light, and on atomic gases, led directly to Erwin Schrödinger's breakthrough to the modern form of quantum mechanics. The book sheds light on why Einstein ultimately renounced his own brilliant work on quantum theory, due to his deep belief in science as something objective and eternal.

This is a fascinating account of two great scientists of the 20th century: Einstein and Heisenberg, discoverers, respectively, of the theory of relativity and quantum mechanics. It connects the history of modern physics to the life stories of these two extraordinary physicists.These discoveries laid the foundation of modern physics, without which our digitized world of computers, satellites, and innovative materials would not be possible. This book also describes in comprehensible terms the complicated science underlying the two discoveries.The twin biography highlights the parallels and differences of these two luminaries, showing how their work shaped the 20th century into the century of physics.

Einstein's View on Theoretical Physics! This short booklet is based on the address (or, its transcript) delivered before the Prussian Academy of Science by Einstein, in 1914, right after he was elected to a member of the Academy. Whether you agree with his opinion or not, Einstein was a deep thinker, and he always had unique views on the topics that were of general interest to people who cared about science (and, humanity). This article, in particular, provided his insight on the role of "principles" in the development of fundamental theories in physics. A must-read for Einstein enthusiasts, or any serious students of physics! This short article/transcript (roughly ~7 minutes) was originally published in German, and it is now in the public domain. This booklet attempts at a new translation to give a somewhat clearer account of what Einstein wanted to convey in his original address. A completely new English translation - 2024!
