Math rockMath rock is a style of alternative and indie rock with roots in bands such as King Crimson and Rush. It is characterized by complex, atypical rhythmic structures (including irregular stopping and starting), counterpoint, odd time signatures, and extended chords. It bears similarities to post-rock. Math rock is typified by its rhythmic complexity, seen as mathematical in character by listeners and critics. While most rock music uses a meter (however accented or syncopated), math rock makes use of more non-standard, frequently changing time signatures such as , , , or .
Id Softwareid Software LLC (ɪd) is an American video game developer based in Richardson, Texas. It was founded on February 1, 1991, by four members of the computer company Softdisk: programmers John Carmack and John Romero, game designer Tom Hall, and artist Adrian Carmack. id Software made important technological developments in video game technologies for the PC (running MS-DOS and Windows), including work done for the Wolfenstein, Doom, and Quake franchises at the time.
MATH-MATICMATH-MATIC is the marketing name for the AT-3 (Algebraic Translator 3) compiler, an early programming language for the UNIVAC I and UNIVAC II. MATH-MATIC was written beginning around 1955 by a team led by Charles Katz under the direction of Grace Hopper. A preliminary manual was produced in 1957 and a final manual the following year. Syntactically, MATH-MATIC was similar to Univac's contemporaneous business-oriented language, FLOW-MATIC, differing in providing algebraic-style expressions and floating-point arithmetic, and arrays rather than record structures.
Heinkel He 219The Heinkel He 219 Uhu ("Eagle-Owl") is a night fighter that served with the German Luftwaffe in the later stages of World War II. A relatively sophisticated design, the He 219 possessed a variety of innovations, including Lichtenstein SN-2 advanced VHF-band intercept radar, also used on the Ju 88G and Bf 110G night fighters. It was also the first operational military aircraft to be equipped with ejection seats and the first operational German World War II-era aircraft with tricycle landing gear.
Rational pointIn number theory and algebraic geometry, a rational point of an algebraic variety is a point whose coordinates belong to a given field. If the field is not mentioned, the field of rational numbers is generally understood. If the field is the field of real numbers, a rational point is more commonly called a real point. Understanding rational points is a central goal of number theory and Diophantine geometry. For example, Fermat's Last Theorem may be restated as: for n > 2, the Fermat curve of equation has no other rational points than (1, 0), (0, 1), and, if n is even, (–1, 0) and (0, –1).
Math warsMath wars is the debate over modern mathematics education, textbooks and curricula in the United States that was triggered by the publication in 1989 of the Curriculum and Evaluation Standards for School Mathematics by the National Council of Teachers of Mathematics (NCTM) and subsequent development and widespread adoption of a new generation of mathematics curricula inspired by these standards. While the discussion about math skills has persisted for many decades, the term "math wars" was coined by commentators such as John A.

RAF GrangemouthRoyal Air Force Grangemouth or more simply RAF Grangemouth is a former Royal Air Force station located north east of Falkirk, Stirlingshire, Scotland. It was opened as the Central Scotland Airport in May 1939 and operated as a Civilian Air Navigation School (CANS) until early September 1939. After the war it was used as Gliding School until 1946. It was then used by RAF Maintenance Command until its closure in June 1955.
2021 Virginia gubernatorial electionThe 2021 Virginia gubernatorial election was held on November 2, 2021, to elect the next governor of Virginia. The election was concurrent with other elections for Virginia state offices. Incumbent Democratic Governor Ralph Northam was ineligible to run for re-election, as the Constitution of Virginia prohibits governors from serving consecutive terms. Businessman Glenn Youngkin won the Republican nomination at the party's May 8 convention, which was held in 37 polling locations across the state, and was officially declared the nominee on May 10.
New MathNew Mathematics or New Math was a dramatic but temporary change in the way mathematics was taught in American grade schools, and to a lesser extent in European countries and elsewhere, during the 1950s1970s. Curriculum topics and teaching practices were changed in the U.S. shortly after the Sputnik crisis. The goal was to boost students' science education and mathematical skills to compete with Soviet engineers, reputedly highly skilled mathematicians. After the Sputnik launch in 1957, the U.S.
