Paul Althaus Smith
Paul Althaus Smith (May 18, 1900June 13, 1980) was an American mathematician. His name occurs in two significant conjectures in geometric topology: the Smith conjecture, which is now a theorem, and the Hilbert–Smith conjecture, which was proved in dimension 3 in 2013. ''Smith theory'' is a theory about homeomorphisms of finite order of manifolds, particularly spheres. Smith was a student of Solomon Lefschetz at the University of Kansas, moving to Princeton University with Lefschetz in the mid-1920s. He finished his doctorate at Princeton, in 1926. His Ph.D. thesis was published in the ''Annals of Mathematics'' that same year. He also worked with George David Birkhoff, with whom he wrote a 1928 paper in ergodic theory, entitled ''Structure analysis of surface transformations'', which appeared in the ''Journal des Mathématiques''. He subsequently became a professor at Columbia University and at Barnard College. His students at Columbia included Sherman K. Stein and Moses Ric ...

1980 Deaths
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 '' Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Suzanne Bloch
Suzanne Bloch (August 9, 1907 – January 29, 2002) was a Swiss-American musician and an influential pioneer of Early Music Revival during the 20th century. Biography Suzanne Bloch was born in Geneva in 1907 into the family of composer Ernest Bloch. The family moved to New York in 1916 when Ernst Bloch took on teaching and conducting responsibilities there. She went to Paris to study music with Nadia Boulanger in 1925, and decided to become a lute player after hearing an early-music concert. She went on to study music in Paris and Berlin, and she met Arnold Dolmetsch in England in 1933. Dolmetsch sold her a lute from 1600 that he had restored himself. In 1935 she performed at the Dolmetsch Early Music Festival in Haslemere, and soon afterward returned to New York, where she began her concert career. Her career as a lutenist was cut short in the 1950s by repetitive stress syndrome brought on by the modern heavily built Hermann Hauser lutes that she played, but her condition all ...

Early Music
Early music generally comprises Medieval music (500–1400) and Renaissance music (1400–1600), but can also include Baroque music (1600–1750). Originating in Europe, early music is a broad musical era for the beginning of Western classical music. Terminology Interpretations of historical scope of "early music" vary. The original Academy of Ancient Music formed in 1726 defined "Ancient" music as works written by composers who lived before the end of the 16th century. Johannes Brahms and his contemporaries would have understood Early music to range from the High Renaissance and Baroque, while some scholars consider that Early music should include the music of ancient Greece or Rome before 500 AD (a period that is generally covered by the term Ancient music). Music critic Michael Kennedy excludes Baroque, defining Early music as "musical compositions from heearliest times up to and including music of heRenaissance period". Musicologist Thomas Forrest Kelly considers that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Billera
Louis Joseph Billera is a Professor of Mathematics at Cornell University. Career Billera completed his B.S. at the Rensselaer Polytechnic Institute in 1964. He earned his Ph.D. from the City University of New York in 1968, under the joint supervision of Moses Richardson and Michel Balinski. Louis Billera served as the first Associate Director of the National Science Foundation Center for Discrete Mathematics and Theoretical Computer Science (DIMACS) at Rutgers University. In 2010 he gave the invited lecture, "''Flag enumeration in polytopes, Eulerian partially ordered sets and Coxeter groups''" at the International Congress of Mathematicians in Hyderabad. Contributions The common thread through much of his research is to study problems motivated by discrete and convex geometry. A sampling includes constructing polytopes to prove the sufficiency condition for the g-theorem (with Carl Lee), discovering fiber polytopes (with Bernd Sturmfels), and studying the space of phylogenetic ...

Moses Richardson
Moses hbo, מֹשֶׁה, Mōše; also known as Moshe or Moshe Rabbeinu ( Mishnaic Hebrew: מֹשֶׁה רַבֵּינוּ, ); syr, ܡܘܫܐ, Mūše; ar, موسى, Mūsā; grc, Mωϋσῆς, Mōÿsēs () is considered the most important prophet in Judaism and one of the most important prophets in Christianity, Islam, the Druze faith, the Baháʼí Faith and other Abrahamic religions. According to both the Bible and the Quran, Moses was the leader of the Israelites and lawgiver to whom the authorship, or "acquisition from heaven", of the Torah (the first five books of the Bible) is attributed. According to the Book of Exodus, Moses was born in a time when his people, the Israelites, an enslaved minority, were increasing in population and, as a result, the Egyptian Pharaoh worried that they might ally themselves with Egypt's enemies. Moses' Hebrew mother, Jochebed, secretly hid him when Pharaoh ordered all newborn Hebrew boys to be killed in order to reduce the population ...
