Maths notation can be wonderfully concise and precise, so it worth thinking about following it closely when programming. One of my favorite examples of this is the numpy `einsum` call [1]. It implements Einstein summation convention [2] - thereby making working with the many dimensions of high-rank tensors feasible. E.g. this (Latex): $C_{ml} = A_{ijkl} B_{ijkm}$ becomes (in Python): C = einsum('ijkl,ijkm->ml', A, B) [1] https://docs.scipy.org/doc/numpy/reference/generated/numpy.einsum.html https://docs.scipy.org/doc/numpy/reference/generated/numpy.e...
