Differential Equations: Summer school (compressed schedule). The professor had a method for going from an equation directly to the 3rd order partial derivative in one step which he would use in class. He would not disclose the method because he was afraid somebody would publish it. He would not publish it himself because he was afraid somebody would find a fault in it.
Organic Chemistry (7:20AM): The instructor was fresh out of industry (oil fields in ND) and not an academic. 1 weekly quiz that I can still recite decades later:
"Given a barrel of crude oil, make a ____ (blank). Use all needed reagents and reactants". He would write on the board what was in the blank... examples where a sandwich baggie, a comb, etc. Destroyed a lot of GPAs.
Lines, Antennas, and Wave Guides: Given a X millawatt transmitter of frequency Y on the moon, design an antenna with Zdb gain... The professor was absolutely brilliant, legally blind, and fiercely independent. He had a multi-lens jewelers magnifier attached to his glasses for when he was out of his office away from his desk magnifier. The equations in this class were extremely long with lots of primes and double prime annotations. The torture came when he went to erase the chalkboard to create more space to write... he would naturally miss portions of letters/variables leaving little marks all over the chalkboard. Then when he reused the space with the new equations we couldn't tell what what a new tick for a prime (ex. alpha' or alpha'') and what was an un-erased artifact of the last set of equations.
And those where the good ol' days.
