Laplace

I love to wake up to the Laplacian for the prolate spheroid in the morning.

Nobody ever told me this definition of a scalar: A scalar is a one-component quantity that is invariant under rotations of the coordinate system.  And for the record, I never knew the significance of invariance until a self discovery a few months ago while walking the trail.

I can't believe I just read this: Tensors are generalizations of scalars.
