What exactly is ∏? I've never quite understood why it is apparent in so many different equations and formulas. Why is it there? Why is it apparent in nature so much? And ∏ it's just a infinite set of numbers why is it any more relevant than any other set of infinite numbers. Why is 3.14.... so important to the fundamental properties of this universe. The same goes with e and ψ and Ω and every other set of numbers. Are all constants just sets of infinitely repeating numbers that are set into different sequences? I am in need of some demystification. Thank you!
