By the way if you are wondering, why this is considered by many the most beautiful equation, here is the small explanation:

"Euler's equation, ( e^{i\pi} + 1 = 0 ), is often considered beautiful because it elegantly ties together five fundamental mathematical constants: ( e ) (the base of natural logarithms), ( i ) (the imaginary unit), ( \pi ) (pi), ( 1 ) (the multiplicative identity), and ( 0 ) (the additive identity). It combines elements from various branches of mathematics (exponentiation, trigonometry, algebra) into a concise and profound statement.

Additionally, it's fundamental in complex analysis and has implications across mathematics and physics, showcasing the interconnectedness of different mathematical concepts."
