Which mathematician is associated with the constant e, approximately equal to 2.718?

Fact

Did you know?

Leonhard Euler, one of the most prolific mathematicians in history, introduced and popularized several mathematical notations still in use today, such as the exponential function and the notion of a mathematical function. The number e, often called Euler's number, is the base of natural logarithms. It is unique because it is the only growth rate for which the exponential function e^x is its own derivative. Euler did not discover this number, but he studied it extensively, which contributed to his association with it. This number appears in many areas of science, including in the calculation of compound interest, the growth of populations, and even in the distribution of prime numbers, demonstrating the deep interconnection between mathematics and the natural world.
