1968réf. 235551968. U.S. Navy women's service press photograph archive released by the U.S. Naval Historical Center in 1968 documenting how the Navy represented women's military labor across World War I World War II and later twentieth century service. The group links the Yeomen F of 1918 the first women formally enlisted in the U.S. Navy to the WAVES established during World War II and still present in postwar naval administration inspection training and ceremony. The photographs show women's military participation as clerical work uniformed discipline barracks life recruitment public parade and institutional remembrance. Photo archive of 11 Large silver gelatin press photographs most measuring 8" x 10" released by the U.S. Naval Historical Center Al images produced in 1968 with images subjects from 1918 to the 1960s. The photos show a Navy Department office in Washington D.C. in 1918 with uniformed and civilian personnel at desks; a woman identified in the caption as "Counselor Eastwood in the office"; a group of WAVES passing in review on an airfield; women marching in formation in New York City during a wartime bond drive; women seated in an auditorium; uniformed officers posed outside a building marked "Uniforms"; a woman in Navy dress working beside a bunk; and a line of women in white shirts and dark skirts marching in formation. Earlier Navy memory appears through portraits of Julia Washington Allen Yeoman F First Class shown with her cap turned to reveal "U.S.N." and "Yeoman F" lettering and Elsie M. Long Yeoman Second Class identified as serving on active duty from October 7 1918 to June 4 1919. A recruiting poster reads "Women awake! Your country needs you. Learn to be of national service. Join the Navy League. Help the Navy local headquarters." Women entered the Navy in large numbers during World War I because clerical expansion created a labor need that could be filled under existing enlistment language; Yeomen F worked as stenographers clerks translators messengers radio operators and office personnel while remaining segregated by gendered expectations of acceptable service. During World War II the WAVES brought women into the Naval Reserve under a formal wartime structure expanding their work into administration communications aviation support supply intelligence training and stateside naval operations. These 1968 release photographs show how the Navy later organized that history for public use: women appear as disciplined personnel administrative workers patriotic recruits and predecessors in a service tradition that the institution could claim as part of its own record. Light surface and corner wear verso captions stamps and release labels. Overall very good condition. An official record of how the U.S. Navy preserved and circulated the history of women's military service from the Yeomen F to the WAVES and their postwar successors. unknown

1926réf. 50187Paris Gauthier-Villars et Cie 1926. 8vo. Bound with orig. printed wrappers in contemp. hcloth. Spine gilt with gilt lettering. A small part of lower spine with a bit of discolouring after a papelabel. A punched stamp on top of title-page. Light wear along edges of boards.VI1331 pp. and 2 pp. of announcements. Textfigs. Internally clean. First edition. In this work De Broglie set forth the idea that electrons as was previously regarded as particles also have wave-quaracters as well as light has. The idea was tested and confirmed by Davisson and Germer the year after in 1927. Also Schrödinger took up the idea and formulated his wave-equation explaning the stationary states of the electron of Niels Bohr by applying De Broglie's concept of electrons as waves to the hydrogen atom. "Thus the duality of both light and matter had been established and physicists had to come to terms with fundamental particles which defied simple theories and demanded two sets of 'complementary' descriptions each applicable under certain circumstances but imcompatible with one another."
