Today I Learned that the people who whine pedantically that the "observer effect" and the "Heisenberg uncertainty principle" are not the same thing, are really just calling out two different aspects of the same phenomenon.
Today I Learned that it was in fact Heisenberg himself who first postulated the existence of the observer effect.

And so, observing someone who makes too much noise about "TEH HEISENBERG UNCERTAINTY PRINCIPLE IS NOT TEH 0BSERVER EFFECT!!!111" makes them look even stupidererer.
