1st Edition. FIRST EDITION, FIRST PRESENTATION of 'Brewster's Angle, "one of Brewster's most important contributions to the science of physics" (Molecular Expressions Website). David Brewster's work on polarization of light by reflection and biaxial crystals "is important for several reasons" (Young, Optics and Lasers, 241). "First, many lasers use Brewster..... More

London: Macmillan, 1932. 1st Edition. FULL VOLUME 1st EDITION of James Chadwick’s initial speculation about the "possible" existence of the neutron, a subatomic particle with no electrical charge and a mass slightly larger than that of a proton. When, three months later, Chadwick affirmed his discovery, his assertion rewrote then..... More

London: Royal Society, 1823. 1st Edition. FIRST EDITION EXTRACT of one in a series of papers on electromagnetism published by the British chemist Humphry Davy between 1821 and 1826.

Lancaster: American Physical Society, 1959. 1st Edition. FIRST EDITION IN ORIGINAL WRAPS. In this paper, Dirac began to apply his methods to the gravitational field. “As a result of simplifications which he introduced [here], it became easy to show that the fourth dynamical constraint is consistent with the others, and.....
