Pierre-Louis LionsPierre-Louis Lions (ljɔ̃ːs; born 11 August 1956) is a French mathematician. He is known for a number of contributions to the fields of partial differential equations and the calculus of variations. He was a recipient of the 1994 Fields Medal and the 1991 Prize of the Philip Morris tobacco and cigarette company. Lions entered the École normale supérieure in 1975, and received his doctorate from the University of Pierre and Marie Curie in 1979.
2022 in scienceThe following scientific events occurred in 2022. January–March 2022 in science#January January–March 2022 in science#February January–March 2022 in science#March 1 April Biochemists report finishing the complete sequence of the human genome. A study shows that, contrary to widespread belief, body sizes of mammal extinction survivors of the dinosaur-times extinction event were the first to evolutionarily increase, with brain sizes increasing later in the Eocene.
Avizo (software)Avizo (pronounce: ‘a-VEE-zo’) is a general-purpose commercial software application for scientific and industrial data visualization and analysis. Avizo is developed by Thermo Fisher Scientific and was originally designed and developed by the Visualization and Data Analysis Group at Zuse Institute Berlin (ZIB) under the name Amira. Avizo was commercially released in November 2007. For the history of its development, see the Wikipedia article about Amira.
KetoneIn organic chemistry, a ketone ˈkiːtoʊn is a functional group with the structure , where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group (which contains a carbon-oxygen double bond C=O). The simplest ketone is acetone (where R and R' is methyl), with the formula . Many ketones are of great importance in biology and in industry. Examples include many sugars (ketoses), many steroids (e.g., testosterone), and the solvent acetone.
Ne WinNe Win (နေဝင်း nè wɪ́ɰ̃; 10 July 1910, or 14 or 24 May 1911 – 5 December 2002) was a Burmese politician and military commander who served as Prime Minister of Burma from 1958 to 1960 and 1962 to 1974, and also President of Burma from 1962 to 1981.

TI-BASICTI-BASIC is the official name of a BASIC-like language built into Texas Instruments (TI)'s graphing calculators. TI-BASIC is a language family of three different and incompatible versions, released on different products: TI-BASIC 83 (on Z80 processor) for TI-83 series, TI-84 Plus series TI-BASIC 89 (on 68k processor) for TI-89 series, TI-92 series, Voyage 200 TI-BASIC Nspire (on ARM processor) for TI-Nspire and TI-Nspire CAS TI rarely refers to the language by name, but the name TI-BASIC has been used in some developer documentation.
Organolithium reagentIn organometallic chemistry, organolithium reagents are chemical compounds that contain carbon–lithium (C–Li) bonds. These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation. Organolithium reagents are used in industry as an initiator for anionic polymerization, which leads to the production of various elastomers.
