New American Oxford Dictionary

Euler, Leonhard

Eu ler, Leonhard |ˈoilər ˈɔɪlər | (1707 –83 ), Swiss mathematician. He attempted to elucidate the nature of functions, and his study of infinite series led his successors, notably Neils Abel and Augustin Cauchy, to introduce ideas of convergence and rigorous argument into mathematics.

 

Euler, Ulf von

Eu ler, Ulf von |ˈɔɪlər ˈoilər | (1905 –83 ), Swedish physiologist; full name Ulf Svante von Euler; son of Hans Euler-Chelpin. He was the first to discover a prostaglandin, which he isolated from semen. Euler also identified norepinephrine as the principal chemical neurotransmitter of the sympathetic nervous system. He shared the 1970 Nobel Prize for Physiology or Medicine with Bernard Katz (1911 –2003 ) and Julius Axelrod (1912 –2004 ).

 

Euler-Chelpin, Hans von

Eu ler-Chel pin, Hans von |ˌoilər ˈkelpin ˌɔɪlər ˈkɛlpɪn | (1873 –1964 ), Swedish biochemist; born in Germany; full name Hans Karl August Simon von Euler-Chelpin. He worked mainly on enzymes and vitamins and explained the role of enzymes in the alcoholic fermentation of sugar. He shared the 1929 Nobel Prize for Chemistry with Arthur Harden (1865 –1940 ).

 

Euler's constant

Eu ler's con stant Mathematics a constant used in numerical analysis, approximately equal to 0.577216. It represents the limit of the series 1 + 1 /2 + 1 /3 + 1 /4 + …1 / n − (natural logarithm of n ), as n tends to infinity. It is not known whether this is a rational number or not. ORIGIN mid 19th cent.: named after L. Euler (see Euler, Leonhard ).

 

Euler's formula

Eu ler's for mu la the geometric formula V − E + F = 2, where V, E, and F are the numbers of vertices, edges, and faces of any simple convex polyhedron or of an equivalent topological graph.
