Essays on Pigeonhole

Discovery

The pigeonhole principle is a simple but powerful concept that is used in tackling combinatorial mathematics problems in a systematic manner. In simple terms, the principle states that if some objects need to be placed in boxes that are lesser in number than the objects, then at least one box will have two objects. The concept was formulated in 1834 by a German mathematician named Peter Gustav Lejeune Dirichlet. In his original publication, Dirichlet used a German word that meant drawer in English (Brualdi, 2008). The word soon changed to pigeonhole that is an open space on a wall ...

It’s a principle that provides the basic and the essential part in the mathematics of sorting and even counting. This principle was introduced by Johann Peter Gustav Lejeune Dirichlet in 1834. He called it the shelf principle or drawer principle. However, many people appreciate his insight and call it the Dirichlet drawer principle. The name pigeonhole was introduced in 1940 by Raphael Robinson. In the literal sense, pigeonholes refer to shelves or holes used to place pigeons. Thus, the principle roughly states that if one has a given number of boxes and a given number of items to ...
