We just finished up our unit on Quantum Mechanics in physics. I was going on and on about Bohr's Principle of Complementarity (Is it a wave or a particle?). I was getting all fired up and calling their attention to the fact that we are limited by our linguistic repetoire. I called our feeling that we must choose between describing fundamental particles "waves" OR "particles" a false dichotomy (we think we are so smart with our fancy words but nature doesn't care - waves and particles are just anthropocentric words; nature does what nature does). As I smugly stepped back to admire my sophisticated grasp of the problem, a couple of students spoke up. "You're beating a dead horse, Mr. Rideout - we get it, move on."
Of course, they are correct, everyone know language is fallible - Bohr himself said it himself long ago (1920):
"We must be clear that when it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections."
But, what I would like to leave my student with is this additional quote from Bohr:
"Anyone who is not shocked by quantum theory has not understood it"
This is the precise opposite of most of physics - usually once you understand some principle of physics you think, how could it be anything but this way?
