The Number "e‪"‬

The Number e Certain numbers hold celebrity status in mathematics. One such number is p, the ratio of the circumference to the diameter in any circle. Like other celebrities, p has become a part of our popular culture. In cartoons, the symbol is often used to indicate the presence of 'smart' people, or even as an icon for 'mathematics' itself. Indeed, many people who know very little else about mathematics are able to recite, from memory, several of the digits of p's infinite, aperiodic, decimal expansion, Ancient and venerable, p has the aura of a very important number.
