"The Power of Nature's Governing Number"
Euler's Number or "e" is a mathematical constant found across fields from quantum mechanics to finance to zoology. Its presence is incredibly influential in growth, change, and decay. The number e is used as the base of the exponential function, and it is used to calculate the exponential decay of radioactive elements, the rate of heat loss, and the exponential growth of bacteria. It is also used to calculate the probability of losing 37 games of roulette in a row and the temperature of the whole universe based on the cosmic microwave background.
