Did you know ? When the idea of computers arose, mathematicians introduced several important theoretical concepts that led to the emergence of fields such as computability theory, computational complexity theory, information theory, and algorithmic information theory. Today, these fields are part of theoretical informatics. Discrete mathematics is a collective name for branches of mathematics particularly useful in computer science.

Did you know ? The oldest signs of geometry can be traced back to ancient Egypt. The Rind Papyrus describes a strikingly accurate method of calculating an approximation of Ludolf's number, with an error of less than one hundredth. The Rind papyrus also describes one of the first attempts at squaring the circle, as well as a certain cotangent analogy.
