My college professor teaching FLUID POWER tried to teach our whole class that air does not compress and liquids do.
When he started the lecture and I attempted to correct him in a very soft and kind way (thinking he obviously is mixing up words) he denied it and told me I was wrong.
I tried several times to correct him nicely (because there were people in the class that would have taken his word) and was met by more and more aggressive denial. I finally stood up in the middle of the class, threw my hands up and said "Well Fuck! I just wasted all this money on a new air compressor" and walked out.
Man, that's insane. It reminds me we had an electrical engineering teacher claim the human eye can't perceive screens refreshing more than 30 times per second (never mind all our computers use 60hz monitors...)
