xkcd #2898: Orbital Argument
(imgs.xkcd.com)
Alt text:
"Some people say light is waves, and some say it's particles, so I bet light is some in-between thing that's both wave and particle depending on how you look at it. Am I right?" "YES, BUT YOU SHOULDN'T BE!"
Remember when we had to list all of our assumptions before making an argument?
Those were good times. (I don't remember when, maybe in Linear Algebra or an engineer or philosophy course.)
