Vectors (and matrices) were ever-present in grad school and I never saw 'em shimmer

Oh I don't know. Trying to imagine the electric and magnetic field vectors in a propagating electromagnetic wave makes my brain shimmer. And shimmer isn't a bad description of what those vectors would look like if you could slow them down, but not too much.

It only takes a couple bourbons to get my brain shimmering but that's just me.

slow vectors down? Vectors are only a form of expression for multiple-dimensional forces and whatnot.
