ref. 1061Braunschweig: Druck und Vieweg. 1st Edition. FIRST EDITION FULL VOLUME OF THE PAPER IN WHICH EINSTEIN PROVIDES THE FIRST DESCRIPTION OF THE NATURE OF THE REFRACTIVE INDEX FOR X-RAYS here clearly demonstrating that phase contrast effects are significant. "Inspired by the presence of fringes at the edges of objects in early X-ray images and by considerations of optical dispersion theory Einstein suggested in 1918 that the real part of the index of refraction for X-rays in matter is slightly less than unity. This was confirmed in 1924 by Larsson et al. in measurements of wavelength-dependent refraction of X-rays by a prism" Hornberger Quantitative Amplitude 1. "A century later most x-ray microscopy and nearly all medical imaging remains based on absorption contrast even though phase contrast offers orders of magnitude improvements in contrast and reduced radiation exposure at multi-keV x-ray energies"ResearchGate November 2015.

The whole issue present= Bd. 38 Heft 2 pp.249-472. Both papers in first edition and they are considered as the first appearance of a Nonlinear Field Equation for Gravitation. - "Einstein published two remarkable memoirs in 1912 which were efforts to construct a complete theory of gravitation incorporating the equivalence principle. In these memoirs Einstein supposed that the gravitational field can be characterized completely by one function the local speed of light analogous to the Newtonian description where only the gravitational potential appears. By an extraordinary argument he extended the potential equation of Newton.In his second Memoir in 1912 he used the equivalence principle to show the influence of a static gravitational field on electromagnetic and thermal processes."

1954ref. 195551954. in German black ink. Signed “A. Einstein”. A poem written by Einstein to his colleague and collaborator Ernst Straus and his son Daniel. “Dear Strausse both! My best wishes and greetings in poetic form. It brings even more happiness If it has been anticipated for so long also in one’s circle of friends the event is doubly appreciated. This is what I wish: Let Daniel be like his father thoroughly intelligent and not less joyous so few humans are like that. Many - alas - are born few are chosen to bring light and joy. Let such gift be his drive. Yours A. Einstein” In German “Strauss” means bunch bouquet etc. or ostrich and “Strausse” is plural. Ernst G. Straus 1922-1983 was a mathematician who helped found the theories of Euclidean Ramsey theory and of the arithmetic properties of analytic functions. He was Einstein’s assistant and collaborator both at Princeton and afterwards when he moved to become a professor of mathematics at UCLA. His son Daniel is a professor of chemistry at Cal State San Jose. unknown
