Eternal E

Eternal E, often called "E," is a mathematical constant approximately equal to 2.71828. It is the base of natural logarithms and plays a crucial role in fields like calculus, complex analysis, and probability theory. E appears naturally in growth processes, such as population increase, radioactive decay, and continuously compounded interest, where quantities grow exponentially. It also has unique properties, such as its derivative being equal to itself, which makes it fundamental in differential equations. In essence, Eternal E is a foundational number that describes continuous, exponential change across various scientific and mathematical contexts.
