Robert McNeesThe students in my upper-level electrodynamics course are taking their final exam right now, which always reminds me of the time I told my students they could bring a formula sheet to the final exam as long as it was on one side of a piece of paper.
Rachel Poretsky@mcnees I'd give them extra points for this!
@microbe I did exactly that. And now I always specify that the formula sheet has to be orientable.
