David Sayre
David Sayre (March 2, 1924 – February 23, 2012) was an American scientist, credited with the early development of direct methods for protein crystallography and of diffraction microscopy (also called coherent diffraction imaging). While working at IBM he was part of the initial team of ten programmers who created FORTRAN, and later suggested the use of electron beam lithography for the fabrication of X-ray Fresnel zone plates. The International Union of Crystallography awarded Sayre the Ewald Prize in 2008 for the "unique breadth of his contributions to crystallography, which range from seminal contributions to the solving of the phase problem to the complex physics of imaging generic objects by X-ray diffraction and microscopy(...)". Life and career Sayre was born in New York City. He completed his bachelor's degree in physics at Yale University at the age of 19. After working at the MIT Radiation Laboratory, he earned his MS degree at Auburn University in 1948. In 194 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Union Of Crystallography
The International Union of Crystallography (IUCr) is an organisation devoted to the international promotion and coordination of the science of crystallography. The IUCr is a member of the International Council for Science (ICSU). Objectives The objectives of the IUCr are to promote international cooperation in crystallography and to contribute to all aspects of crystallography, to promote international publication of crystallographic research, to facilitate standardization of methods, units, nomenclatures and symbols, and to form a focus for the relations of crystallography to other sciences. The IUCr fulfils these objectives by publishing in print and electronically primary scientific journals through the ''Acta Crystallographica'' journal series, as well as ''Journal of Applied Crystallography'', ''Journal of Synchrotron Radiation'', '' IUCrJ'', the series of reference volumes ''International Tables for Crystallography'', distributing the quarterly ''IUCr Newsletter'', mai ...

Physics Today
''Physics Today'' is the membership magazine of the American Institute of Physics. First published in May 1948, it is issued on a monthly schedule, and is provided to the members of ten physics societies, including the American Physical Society. It is also available to non-members as a paid annual subscription. The magazine informs readers about important developments in overview articles written by experts, shorter review articles written internally by staff, and also discusses issues and events of importance to the science community in politics, education, and other fields. The magazine provides a historical resource of events associated with physics. For example it discussed debunking the physics of the Star Wars program of the 1980s, and the state of physics in China and the Soviet Union during the 1950s and 1970s.

John Backus
John Warner Backus (December 3, 1924 – March 17, 2007) was an American computer scientist. He directed the team that invented and implemented FORTRAN, the first widely used high-level programming language, and was the inventor of the Backus–Naur form (BNF), a widely used notation to define formal language syntax. He later did research into the function-level programming paradigm, presenting his findings in his influential 1977 Turing Award lecture "Can Programming Be Liberated from the von Neumann Style?" The IEEE awarded Backus the W. W. McDowell Award in 1967 for the development of FORTRAN. He received the National Medal of Science in 1975 and the 1977 Turing Award" for profound, influential, and lasting contributions to the design of practical high-level programming systems, notably through his work on FORTRAN, and for publication of formal procedures for the specification of programming languages". He retired in 1991 and died at his home in Ashland, Oregon on March ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anne Sayre
Anne Sayre ( Colquhoun; April 10, 1923 – March 13, 1998) was an American writer well known for her biography of Rosalind Franklin, one of the discoverers of the structure of DNA. She was married to an American crystallographer David Sayre (1924–2012). Her literary contributions are in short stories, the earnings from which she supported her husband during his PhD course. She achieved her lifelong educational ambition of getting a law degree in her early 50s. She ultimately became justice of the local court in Head of the Harbor, New York. She was a lifelong friend of Franklin, who played a key role in the discovery of the chemical structure of DNA. A strong feminist, her 1975 book, ''Rosalind Franklin and DNA'', became an exposition of the account of sexism in the scientific community on one hand, and the true genius of the Rosalind Franklin in her contributions to molecular biology on the other hand.
