Euler’s identity, often written as e^(iπ) 1 = 0, is celebrated as one of the most beautiful equations in mathematics because it unites five of the most fundamental constants in a single, simple expression. The number e represents the base of natural logarithms and arises in continuous growth processes; i is the imaginary unit, satisfying i² = −1 and forming the foundation of complex numbers; π connects geometry through the ratio of a circle’s circumference to its diameter; and 1 and 0 symbolize
