Theorems about circles | Geometry of numbers
In the geometry of numbers, Schinzel's theorem is the following statement: Schinzel's theorem — For any given positive integer , there exists a circle in the Euclidean plane that passes through exactly integer points. It was originally proved by and named after Andrzej Schinzel. (Wikipedia).
Irreducibility and the Schoenemann-Eisenstein criterion | Famous Math Probs 20b | N J Wildberger
In the context of defining and computing the cyclotomic polynumbers (or polynomials), we consider irreducibility. Gauss's lemma connects irreducibility over the integers to irreducibility over the rational numbers. Then we describe T. Schoenemann's irreducibility criterion, which uses some

The Schrodinger Equation is (Almost) Impossible to Solve.
Sure, the equation is easily solvable for perfect / idealized systems, but almost impossible for any real systems. The Schrodinger equation is the governing equation of quantum mechanics, and determines the relationship between a system, its surroundings, and a system's wave function. Th
