History of the SATThe SAT is a standardized test commonly used for the purpose of admission to colleges and universities in the United States. The test, owned by the College Board and originally developed by Carl Brigham, was first administered on June 23, 1926, to about 8,000 students. The test was introduced as a supplement to the College Board essay exams already in use for college admissions, but ease of administration of the SAT and other factors led to the discontinuation of the essay exams during World War II.
Logan-Rogersville High SchoolLogan-Rogersville High School (LRHS) is a public high school for grades 9–12 located in Rogersville, Missouri as part of the Logan-Rogersville R-VIII School District. The National Center for Education Statistics classifies LRHS as a "rural fringe" locale, which is defined as a rural area that is less than or equal to 5 miles from an urban area. The mascot of LRHS is the wildcat with the colors of maroon and white. LRHS was the site for the Guinness World Records largest game of duck, duck, goose with 2,135 participants on October 7, 2011.
Fermat's Last TheoremIn number theory, Fermat's Last Theorem (sometimes called Fermat's conjecture, especially in older texts) states that no three positive integers a, b, and c satisfy the equation an + bn = cn for any integer value of n greater than 2. The cases n = 1 and n = 2 have been known since antiquity to have infinitely many solutions. The proposition was first stated as a theorem by Pierre de Fermat around 1637 in the margin of a copy of Arithmetica. Fermat added that he had a proof that was too large to fit in the margin.
Root of unityIn mathematics, a root of unity, occasionally called a de Moivre number, is any complex number that yields 1 when raised to some positive integer power n. Roots of unity are used in many branches of mathematics, and are especially important in number theory, the theory of group characters, and the discrete Fourier transform. Roots of unity can be defined in any field. If the characteristic of the field is zero, the roots are complex numbers that are also algebraic integers.
Fermat numberIn mathematics, a Fermat number, named after Pierre de Fermat, the first known to have studied them, is a positive integer of the form where n is a non-negative integer. The first few Fermat numbers are: 3, 5, 17, 257, 65537, 4294967297, 18446744073709551617, ... . If 2k + 1 is prime and k > 0, then k itself must be a power of 2, so 2k + 1 is a Fermat number; such primes are called Fermat primes. , the only known Fermat primes are F0 = 3, F1 = 5, F2 = 17, F3 = 257, and F4 = 65537 ; heuristics suggest that there are no more.
