1949ref. 148432Evanston: The Library of Living Philosophers Inc. 1949. First edition of Einstein's singular autobiography. Octavo original cloth with gilt titles to the spine top edge gilt frontispiece of Einstein by Yousuf Karsh. Edited by Paul Arthur Schilpp. In near fine condition. Written by the man considered the "Person of the Century" by Time magazine this is not a glimpse into Einstein's personal life but an extension and elaboration into his thinking on science. Two of the great theories of the physical world were created in the early 20th century: the theory of relativity and quantum mechanics. Einstein created the theory of relativity and was also one of the founders of quantum theory. Here Einstein describes the failure of classical mechanics and the rise of the electromagnetic field the theory of relativity and of the quanta. "The greatest physicist of the 20th century" PMM 408.

Slight nick at bottom edge of lower wrap else better than very good. Includes the retort by Einstein and Rosen originators of speculation on the existence of "worm-holes" in spacetime to objections made to the general theory of relativity. According to Galina Weinstein: "Between 1935 and 1936 Einstein was occupied with the Schwarzschild solution and the singularity within it while working in Princeton on the unified field theory and with his assistant Nathan Rosen on the theory of the Einstein-Rosen bridges. He was also occupied with quantum theory. He believed that quantum theory was an incomplete representation of real things. Together with Rosen and Boris Podolsky he invented the EPR paradox. I demonstrate that the two-body problem in general relativity was a heuristic guide in Einstein's and collaborators' 1935 work on the Einstein-Rosen bridge and EPR paradox."

1906ref. 292Leipzig: Barth 1906. 1st Edition. FIRST EDITION FIRST ISSUE of two important 1906 Einstein papers. Einstein wrote two papers on the photoelectric effect his revolutionary 1905 paper and "Zur Theorie der Lichterzeugung und Lichtabsorption" his continuation of it. In them Einstein employed Planck's theory that luminous energy can be absorbed or emitted only in discrete amounts called quanta and proposed a theory of light quanta involving particles with no mass photons whose energy depended on frequency. All of Einstein's experimental results confirmed that light actually consisted of discrete energy packets. "Based on this theory Einstein wrote an equation describing how the photoelectric effect works. The energy of individual electrons emitted by a photocell is a function of the frequency of the light hitting the photocell and the rate of electron emission is a function of the light source's intensity number of photons with sufficient energy being emitted. This is contrary to what is predicted by classical physics" History of Physics: The Wenner Collection. In this Einstein's second paper on photoelectrics he revisited Planck's theory and from it developed his ideas to show that an electromagnetic wave such as light could be described as a particle photon with discrete quanta of energy that was dependent on its frequency. In the long history of quantum mechanics this would lead to a theory of unity between subatomic particles and electromagnetic waves called wave-particle duality in which particles and waves were neither one nor the other but had certain properties of both. At first Einstein believed that light-quantum hypothesis was merely 'heuristic': that it behaved only as if it consisted of discontinuous quanta. But in this paper and others to follow Einstein used his statistical mechanics to demonstrate that when light interacts with matter Planck's entire formula can arise only from the existence of light quanta -- not from waves. In other words in explaining the photoelectric effect by extending Planck's concept of quantum of energy had Einstein "demonstrated that his own 'light-quantum hypothesis' was implicit in Planck's earlier work" Honner The Description of Nature 31. ALSO included in this volume is "Daz Prinzip von der Erhaltung." The Principle of Conservation of Motion of the Center of Gravity and the Inertia of Energy. In this "ingenious thought experiment involving energy transport in a hollow cylinder Einstein returned to the relationship between inertial mass and energy giving more general arguments for their complete equivalence" Calaprice The Einstein Almanac 18. This was the first statement that the conservation of mass is a special case of the conservation of energy. CONDITION & DETAILS: Leipzig: Barth 1906. Octavo. 8.75 x 6 inches; 222 x 152mm.

Zur affinen Feldtheorie. Offprint from Sitzungsberichten der Preussischen Akademie der Wissenschaften 1923. XVIII. 8vo.4 137-140 First edition. Orange wrappers. A fine fresh copy in the rare off-print form marked with an asterisk by Weil denoting a major paper "Sonderabdruck" & deemed of sufficient interest that a translation was published in Nature Magazine. "Einstein's attempts to formulate a unified field theory the theoretical framework to account for the fundamental forces of nature. stemmed from his dissatisfaction with the general relativity theory which did not adequately incorporate the electromagnetic field into the geometry of space-time". Einstein's first investigation of Weyl's ideas published in the present paper which Weyl had begun working on in 1918. Weyl was investigating the possibility of constructing a unified field theory preserving the dimensionality of space-time while formally altering its geometry making it a special case of the class known as affine geometries. However Einstein later rejected Weyl's theory. "Weil No. 132; Schilpp--Shields No. 171; Alicke No.113; Norman Library 698; Boni 141. Affine Geometry is not concerned with the notions of circle angle and distance. It's a known dictum that in Affine Geometry all triangles are the same. In this context the word affine was first used by Euler affinis. In modern parlance Affine Geometry is a study of properties of geometric objects that remain invariant under affine transformations mappings. Affine transformations preserve collinearity of points: if three points belong to the same straight line their images under affine transformations also belong to the same line and in addition the middle point remains between the other two points." The early Offprints from "Sitzungsberichten." are called "Sonderabdruck" up to Weil No.165 including this. From Weil 166 they are called "Sonderausgabe.". - Before 161 up to 160 the Offprints do not have separate title and pagination the pagination follows the numbering in the periodical. From 166 the Offprint has both separate printed title and pagination. - So Weil Nos 161-165 is still "Abdruck" but with separate title and pagination.

Einstein discusses the concept of the aether in relation to his theory of relativity. This lecture examines the historical role of the aether in physics and its transformation under relativity. His conclusion is that relativity does not bring back the classical aether but introduces a new understanding of space as an active structured entity. The text of this speech delivered at Leiden University was also translated into French in 1921. The English translation appeared in Einstein's "Sidelights of Relativity" published at London in 1922. Einstein's manuscript is now kept in the Bibliotheca Bodmeriana Geneva. - Weil 111; Boni Russ and Laurence 115; Roller/Goodman I 354; Seelig 131; Schilpp-Shields 131. SCIENCE: PHYSICS ; Berlin, (E.

The paper "represents the basis of the one written by the same author in collaboration with Wolfgang Pauli in 1943 in which by following analogous lines the proof of the non-existence of regular particle-type solutions was generalized to the case of cilyndrical geometries in Kaluza-Klein theory Einstein & Pauli 1943. Besides other generalizations were subsequently presented. The non-existence of such solutions in classical unified field theory was undoubtedly an important criterion leading Einstein's investigations."Galvagno and Giribet."In his search for a unified field theory that could undercut quantum mechanics Einstein considered five-dimensional classical Kaluza-Klein theory. He studied this theory most intensively during the years 1938-1943. One of his primary objectives was finding a non-singular particle solution. In the full theory this search got frustrated and in the x5-independent theory Einstein together with Pauli argued it would be impossible to find these structures."
