Pi is everywhere in physics. Why is that.
Pi occurs naturally in the mathematics of cyclic or oscillatory behavior.
π is only one of several fundamental constants that turn up in Science. e is a constant that is involved in the description of non-cyclic changes - growth and decay. But those two constants have an odd relationship with each other and other mathematical constants
It also happens that
eπi = -1
That's something 'inside Maths' which everyone finds exciting and, to my mind, it's at least as interesting as E=mc2. When we were told that for the first time, the whole class were shuffling in their seats with amazement.
