(Mystery Equation) T-Shirt

I am not permitted to tell you about this equation! Sorry, but the manufacturer has deemed that information a menace to disabled people and abhorrently politically incorrect physics! I will say only that it relates to propagation delays in electromagnetic waves, according to Maxwell's Equations. One would not have supposed that to be so terribly harmful ... but then one isn't in charge around here, is one? I'll bet there are Republicans (excuse my use of the "R" word) involved in this somehow; they are, after all, notoriously hostile to science — and indeed to Enlightenment values generally. __________
