Donald M. Davis (mathematician)
Donald M. Davis (born 7 May 1945) is an American mathematician specializing in algebraic topology. Davis received a B.S. from MIT in 1967 and a PhD in mathematics at Stanford in 1972, directed by R. James Milgram. After postdoctoral positions at University of California, San Diego and Northwestern University, he began a 50-year career at Lehigh University in 1974. In 2012 he was named an inaugural Fellow of the American Mathematical Society. . Since 2002, he has been Executive Editor of ''Homology, Homotopy and Applications''. Research Davis has published in algebraic topology, differential topology, topological robotics, and combinatorial number theory. He is an expert on immersions of projective spaces, and maintains a website with all known results for real projective spaces. He computed the v_1-periodic homotopy groups of all compact simple Lie groups. Coaching In 1993 Davis started the Lehigh Valley Math Team. In 2005, 2009, 2010, 2011, and 2024, they were ...

Fort Knox
Fort Knox is a United States Army installation in Kentucky, south of Louisville and north of Elizabethtown. It is adjacent to the United States Bullion Depository, which is used to house a large portion of the United States' official gold reserves, and with which it is often conflated. The base covers parts of Bullitt, Hardin and Meade counties. It currently holds the Army Human Resources Center of Excellence, including the Army Human Resources Command. It is named in honor of Henry Knox, Chief of Artillery in the American Revolutionary War and the first United States Secretary of War. For 60 years, Fort Knox was the home of the U.S. Army Armor Center and the U.S. Army Armor School, and was used by both the Army and the Marine Corps to train crews on the American tanks of the day; the last was the M1 Abrams main battle tank. The history of the U.S. Army's Cavalry and Armored forces, and of General George S. Patton's career, is shown at the General George Patton Museum ...

Combinatorial Number Theory
Number theory (or arithmetic or higher arithmetic in older usage) is a branch of pure mathematics devoted primarily to the study of the integers and integer-valued functions. German mathematician Carl Friedrich Gauss (1777–1855) said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics."German original: "Die Mathematik ist die Königin der Wissenschaften, und die Arithmetik ist die Königin der Mathematik." Number theorists study prime numbers as well as the properties of mathematical objects made out of integers (for example, rational numbers) or defined as generalizations of the integers (for example, algebraic integers). Integers can be considered either in themselves or as solutions to equations (Diophantine geometry). Questions in number theory are often best understood through the study of analytical objects (for example, the Riemann zeta function) that encode properties of the integers, primes or other number-theoretic objects i ...

21st-century American Mathematicians
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius ( AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman empero ...

HMMT
HMMT is an annual high school math competition that started in 1998. The location of the tournament, in Cambridge, Massachusetts, alternates between Harvard University (November tournament) and MIT (February tournament). The contest is written and staffed almost entirely by Harvard and MIT students. Naming HMMT was initially started as the Harvard-MIT Mathematics Tournament in 1998, and is frequently still referred to as such by much of the math community. In 2019, HMMT rebranded as just HMMT to meet requirements set forth by Harvard and MIT, making it an orphan initialism. Tournament format HMMT February is attended by teams of eight students each. Teams can represent a single school, or a regional math team as large as a state. In recent years, teams have represented over 20 states, as well as Africa, Asia, Europe, and South America. HMMT February consists of three rounds: the Individual Round, the Team Round, and the Guts Round. No calculator or computational aids of any ...

Simple Lie Group
In mathematics, a simple Lie group is a connected non-abelian Lie group ''G'' which does not have nontrivial connected normal subgroups. The list of simple Lie groups can be used to read off the list of simple Lie algebras and Riemannian symmetric spaces. Together with the commutative Lie group of the real numbers, \mathbb, and that of the unit-magnitude complex numbers, U(1) (the unit circle), simple Lie groups give the atomic "blocks" that make up all (finite-dimensional) connected Lie groups via the operation of group extension. Many commonly encountered Lie groups are either simple or 'close' to being simple: for example, the so-called "special linear group" SL(''n'') of ''n'' by ''n'' matrices with determinant equal to 1 is simple for all ''n'' > 1. The first classification of simple Lie groups was by Wilhelm Killing, and this work was later perfected by Élie Cartan. The final classification is often referred to as Killing-Cartan classification.
