Page from the Guest Book Register of the Hebrew College in Havana Cuba signed by Albert Einstein in 1930.

1930019304Havana Cuba: not published 1930. Book. Very good- condition. Unbound. Signed by Authors. First Edition. Folio - over 12 - 15" tall. A page from the guest book register of the Hebrew College in Havana Cuba signed by Albert Einstein. On his journey to America the scientist stopped in Havana for a little over a day. In addition to touring the island and meeting dignitaries Einstein first traveled to the Jewish community and specifically the "Colegio Hebrew del Centro Israelita de Cuba" during his 30 hour visit to Cuba which started on December 19 1930. The double-sided guest book page has 16 entries dating from September 12 1929 to March 9 1931. Some of the visitors who signed the guest book were from the island but several were from the USA. Most of the American visitors were fellow Zionists and/or helped to raise funds for various Jewish causes. The Director of the Hebrew College at that time as identified on the sheet is Dr. Juan del Valle. The page was folded and has numerous paper clip creases and rust stains a few small perforations from staples and has moderate soiling and wear. Included is also a small loose contemporary newsprint photograph of Einstein from a Spanish language newspaper. The entries in chronological order as best as could be transcribed are: 09/12/29 O. Lopez as Inspector Auxilier; 11/14/29 Oscar Lopez giving address as 177 Enrique Villuendas; lengthy handwritten comment in Spanish by O. Lopez; 12/12/29 Dr. Abraham Coralnik 1883-1937 of New York - lengthy handwritten comment in English by Coralnik who was Editor of "The Day" a Yiddish NY newspaper; No date n.d.

Spielen Gravitationsfelder im Aufbau der materiellen Elementarteilchen eine wesentliche Rolle Do Gravitational Fields Play an Essential Role in the Structure of the Elementary Particles of Matter

19191857Berlin: Königlich Akademie der Wissenschaften 1919. First Edition. Fine. FIRST EDITION IN ORIGINAL WRAPPERS of one of Einstein's major papers on the modification of general relativity and the beginning of his unified field theory. "As so often the case in relativity the story of quantum gravity begins with Einstein himself. Soon after the final formulation of general relativity he pointed out the need for a quantum modification of the theory. In "Do Gravitational Fields Play an Essential Role in the Structure of the Elementary Particles of Matter" he began to speculate whether gravitation plays a role in the atomistic structure of matter: There are reasons for thinking that the elementary formations which go to make up the atom are held together by gravitational forces. The above reflections show the possibility of a theoretical construction of matter out of the gravitational field and the electromagnetic field alone. "In order to construct such a model of an 'elementary particle' Einstein shows that it is necessary to modify the original gravitational field equations. The major interest of this paper is that his attention now shifted from possible quantum modifications of general relativity to the search for a unified theory of the electromagnetic and gravitational fields on the basis of which he hoped to explain the structure of matter. Quantum effects are to be derived from such a theory rather than postulated ad hoc. Einstein remained committed to this approach for the rest of his life: the search for a 'natural' mathematical extension of the general theory in the hope that such a theory would somehow explain the quantization of matter and energy" Iyer and Bhawal Black Holes Gravitational Radiation and the Universe.

Strahlungs-Emission und -Absorption nach der Quantentheorie Emission and Absorption of Radiation in Quantum Theory

19162364Braunschweig: Druck und Verlag von Friedr Vieweg and Son 1916. First edition. Original wrappers. Very Good. FIRST PRINTING IN ORIGINAL WRAPPERS OF ONE OF EINSTEIN'S MAJOR WORKS: HIS FIRST PAPER ON THE DERIVATION OF PLANK'S LAW AND PROVIDING THE THEORETICAL BASIS FOR THE LASER. "Einstein commended the 'unparalleled boldness' of Planck's derivation of 1900 meaning not only the problem itself but also the fact that it was based on assumptions that were not entirely free of contradictions. Einstein now succeeded in the first of two papers in eliminating that flaw. More interesting than the derivation itself was the general character of his methods. Einstein proceeded from Niels Bohr's basic--and by then well tested--assumption that the electrons within an atom occupy a number of discrete energy states and are able through emission or absorption of radiation to pass from one of those states to another. Added to this was an assumption of thermodynamic equilibrium between radiation field and atom as well as a consideration of the 'classical' limiting case at high temperatures--and there was Planck's formula. This brief argument. also covers emission stimulated by the radiation field; thus the formulas already by implication contain the theory of the laser though it was to take nearly half a century to be realized" Folsing Albert Einstein 389. Weil 85. The "implication" containing the theory of the laser was more fully developed in his companion paper "On the Quantum Theory of Radiation" published a few weeks later. In the first paper Einstein wrestled with the concept that the atomic emission of radiation could be a directed process; in the second paper he convincingly demonstrates that this is indeed the case.
