### Truly Beautiful. If you can’t see the elegance of this, I only wish you could. It ties together the imaginary number, the exponential, pi, 1 and 0. The imaginary number is derived out of necessity in algebra. The exponential number was invented for calculus for logarithmic and exponential functions, pi is essential in tying together geometry, and 1 and 0 are……well, everything. This equation ties together algebra, calculus, geometry, and basic numerology.
