Boy's SurfaceGeometryPaul NylanderBoy's Surface was discovered in 1901 by German mathematician Werner Boy when he was asked by his advisor, David Hilbert, to prove that an immersion of the projective plane in 3-space was impossible. Today, a large model of Boy's Surface is displayed outside of the Mathematical Research Institute of Oberwolfach in Oberwolfach, Germany. The model was constructed as well as donated by Mercedes-Benz.
Boy's Surface VocabularyGeometryPaul NylanderWhile trying to prove that an immersion (a special representation) of the projective plane did not exist, German mathematician Werner Boy discovered Boy’s Surface in 1901. Boy’s Surface is an immersion of the projective plane in three-dimensional space. This object is a single-sided surface with no edges.

Pascal's triangleDepicted on the right are the first 11 rows of Pascal's triangle, one of the best-known integer patterns in the history of mathematics. Each entry in the triangle is the sum of the two numbers above it. Pascal's triangle is named after the French mathematician and philosopher Blaise Pascal (1623-1662), who was the first to write an organized work about the properties and applications of the triangle in his treatise, Traité du triangle arithmétique (Treatise on Arithmetical Triangle) in 1653.<ref name = "wiki:Pascal's triangle">Wikipedia (Pascal's Triangle).

Pascal's triangle plays important roles in probability theory, in algebra, in combinatorics, and in number theory.
Pigeonhole PrincipleA pigeon is looking for a spot in the grid, but each box or pigeonhole is occupied. Where should the poor pigeon on the outside go? No matter which box he chooses, he must share with another pigeon. Therefore, if we want all of the pigeons to fit into the grid, there is definitely a pigeonhole that contains more than one pigeon. This concept is commonly known as the pigeonhole principle. The pigeonhole principle itself may seem simple but it is a powerful tool in mathematics.
