@n3tcat I think you can also use it to determine the chemical composition of distant stars -- and also their relative velocities, by looking at the gender-shift.
@rachel@n3tcat i think the analogy works pretty well, if you consider the slits to be the binary genders and the screen behind the actual spectrum of genders
@n3tcat What do you mean, my gender keeps fluctuating and you can't keep track? It hasn't changed for years. Oh, you mean in the time domain ... well, if you insist on looking at it that way...
