“I told a class ‘...you may think this is useless, but it is INCREDIBLY useless!’ I wanted to say ‘incredibly useful’.”
“In my computer lab, a student got up to try to put down a shade. The shade was a 30+-year-old, metal, 6-foot long monster. It fell off the wall while he was pulling on the cord and slammed down on top of 4 or 5 computers in a huge cloud of dust and debris. After a few seconds, the student, still holding the cord in his hand said sheepishly…’that would be my fault’."
“We had those sliding blackboards, and I pushed the front one up (I'm 6'3") and knocked it into the big wooden speaker on the wall, which fell onto my head. The nurse was right across the hall, and as I was leaving to go to the hospital to get 7 stitches, my Physics class showed me that while I was in the nurse's office they had approximated the mass of the speaker, and the distance it fell, and computed the amount of energy transferred from the speaker to my head.”
