These are the essential papers conceiving the new science of X–ray crystallography. It studies the structure of solids, particularly crystals, with X–ray as the primary tool, and their discoveries won the Braggs (father, W. H. and son, W. L.) a 1915 Nobel Prize in physics (“for their services in the analysis of crystal structure by means of X–rays”). Along the way they formulated Bragg’s law of diffraction (n =2d sin ) and they invented the X–ray spectrometer, and their physics leaked into chemistry through Moseley’s nearly simultaneous reconstruction of The Periodic Table, and then later, Perutz’s contributions to the recognition of life’s chemical basis (DNA). But wait, there’s less. William Henry served as President of The Royal Society from 1935 to 1940. “It was Einstein who made the real trouble. He announced in 1905 that there was no such thing as absolute rest. After that there never was.”–Stephen Leacock, 1947.
