82. July 5 - Today In Science History applied to the particle rather than the quantity of charge. OskarBolza. Died 5 Jul 1942 (born 12 May 1857) German mathematician http://www.todayinsci.com/7/7_05.htm

JULY 5 - BIRTHS Ernst Mayr (source) Born 5 Jul 1904. German-born American biologist known for his work in avian taxonomy, population genetics, and evolution. In 1928, he led the first of three expeditions to New Guinea and the Solomon Islands where he studied the effects of geographic distribution among various animal species. He led development of the modern synthetic theory of evolution (the interplay of gene mutation and recombination, changes in structure and function of chromosomes, reproductive isolation and natural selection). In 1940, he proposed a definition of species that became accepted in scientific circles. He began bird watching as a young boy, and by the age of ten, he could recognize all of the local bird species by call as well as sight. John Howard Northrop (source) Born 5 Jul 1891; died 27 May 1987. American biochemist who received (with James B. Sumner and Wendell M. Stanley) the Nobel Prize for Chemistry in 1946 for successfully purifying and crystallizing certain enzymes, thus enabling him to determine their chemical nature. During WW I, he conducted research on fermentation processes suitable for the industrial production of acetone and ethyl alcohol. This work led to a study of enzymes essential for digestion, respiration, and general life processes. He crystallized pepsin (1930), a digestive enzyme present in gastric juice, and found that it is a protein, thus resolving the dispute over the nature of enzymes. Using the same chemical methods, he isolated the first bacterial virus (bacteriophage), and found it is a nucleoprotein (1938).

Among other topics, the author describes the landmark results of Weierstrass on sufficient conditions for the extremum of a functional in terms of the second variation. Also discussed are Kneser's sufficient conditions, Weierstrass's theory of the isoperimetric problem, and Hilbert's theorem on the existence of an extremum of an integral. Although the original book was written nearly 100 years ago, it remains very useful in learning about classical calculus of variations.

Papers of Professor William Henry Young, and Grace Chisholm Young Biographical notes Arrangement of the archive Summary guide to the archive Related collections held by the University ... Bibliography Biographical notes William Henry Young Publications: Fundamental Theorems of the Differential Calculus , 1910; nearly 200 mathematical papers, as well as articles on educational and academic topics; jointly with his wife, Theory of Sets of Points First Book of Geometry , 1905 (translated into German as Der Kleine Geometer , 1908, also Italian, Swedish (1920), and Magyar (1925). Grace Chisholm Young Born 1868, married 1896. Educated at Girton College, Cambridge, also Oxford (1892); Doctorate from Gottingen 1895 (first woman allowed a degree in Prussia). Studied medicine at Gottingen and Geneva. Publications: for joint books with her husband see above; articles in Nature ; poems; mathematical and astronomical papers. Arrangement of the archive The Young papers have been listed in the categories into which they had been sorted before their deposit in the University Archives in 1976. This organisation was preserved as adding a valuable extra dimension to the archive since it was the work of successive persons with detailed knowledge of the family and mathematical background. One of these organisers of the archive was the eldest daughter, Dr Cecily Tanner, who wrote a note explaining the background thus: "Both William Henry and Grace Chisholm Young had as their first love an interest in history and this included family history. William Henry Young particularly hoped that as it did for him, their own life and the upbringing of their children, as far as preserved letters might show, would give the next generation a conscious sense of their background in their own careers. Other papers were systematically destroyed because each successive home was to be a temporary one, and last no more than seven years at the outside, until in the later 1920s the idea of a return to England for permanent family residence was abandoned.
