Analogies

This is about a professor I TA for. He is Swiss, and teaches in a very interesting way. He jumps about the class, and explains everything with lots of actions, but that won't probably be effective in words, you have to see it...

His analogies are out of the world too. And I being the TA, can actually take notes on anything I want.. So here, I present his brilliant masterpieces almost verbatim.

Topic: Stress, Strain and Elastic Limit

Prof: "I am sitting on this table and the leg of the table is getting pushed down."(He swings his legs wildly, sitting on the table)"Now, if I eat a lot and weigh twice as much what happens?? "(This while making actions of stuffing food in his mouth with both hands)

A student says: " The table leg gets squishes more".

Prof: "Yes, this squishing is called Strain. "

"Now if I eat too much, and get too fat, I won't remain in the elastic limit. If I am still eating a lot, a lot of chips and cheese and icecream, and become an elephant, the table wobbles, and the leg breaks and the elephant is scared and runs around the room."( And he actually ran around the room with scared expressions!!!!) " This is called fracture, not of the elephant's leg because of the running, but of the leg of table."

Topic: Ferroelectric Domains and Curie Temperature

Prof: " We are all holding hands and looking at the sun, since it is a bright sunny day. As it gets warmer, we get restless, and our palms get sweaty. So we let go off hands and start moving about, talking to our friends in the chains. "

"This is exactly what domains in iron do, when they are heated up, they loose their orientation."

Topic: Bending of light, Refraction

"Suppose you want to shoot the sun, you pick up a rifle, and aim at it through the closed classroom window. Since the light bends due to refraction in the window glass, your aim would be off. But the sun is so big, that you might hit it anyway, so the sun is a fantastic shooting target."

This guy's awesome, if you get so entertained in a Physics class, you are unlikely to ever forget the concept.
