Sorry to hear that Professor Mischke has passed. I just found out because i ordered a copy of one of his books for my daughter. (I am keeping mine forever.) I hope that I can impress upon her the importance of this book.
I had him for only one class (mechanisms, ME 310), and was never so happy to receive a C- in a class before. He was tough, but VERY knowledgeable.
He was a terrific author, and his book " Mathematical Model Building: An Introduction to Engineering by Charles R. Mischke" is a genuinely brilliant introduction to engineering. He was teaching us optimization, but at the time, I was too stupid to know it.
The day before our final exam, Prof. Mischke said that the test was at noon. He asked the class, "is noon AM or PM?" The class stayed silent, until Prof. Mischke said, "Neither. It's M. Meridian" A classmate behind me whispered, "then, what's midnight?" I thought it was a good question, so I raised my hand, and asked, "What's midnight?"
He thought for a minute, and then shook his head, and shrugged his shoulders. I think that might have been the only time he didn't have an answer. I am sure that if he didn't know, he was going to find out.
The engineering world lost a legend. Condolences to the family.
