tale of two nozzles

I remember my undergrad class about gasdynamics. My professor is Dr. Ramohalli. I'm not sure what he is talking about and and couldn't decipher his words but all I can get is through reading and his drawing on the blackboard. One thing i remember is he always like to link our course to the old stories from Charles Dickens, one of them is the Tale of the two Cities and he changed it to nozzle. The converging and diverging nozzle. His exams are relatively easy and when people asked about some clarification during the test, he will, accidentally, tell the answer. Some of them try to sit at the front for next test to hear some QAs.

Well, but I do not like that course very much because I do not want to get an A in my test but fail to understand what it is all about. That's why I had to sell the book and I felt regret now that I need it most.
