Yeah, unpredictably my fav classes were Physics, Chemistry, and Genetics - all because of the profs.
My physics teacher was awesome, he was young, had long black hair past his scapulas, 6 piercings in both ears, wore all black, was the dept head and said that one of the reasons physics is cool because is because it explains the math involved in throwing stuff at people lol. He explained things in a way I could understand. I took that guy for both physics, and trig and calculus. He also wrote my LOR, and I'm inviting him to my wedding this summer 🙂
My Genetics prof told stories alllll the time and he told us that the guy who named the F-factor was a total lech and sleeze, and that F-factor itself stood for "F_ck- factor." From then on, I could always remember what exactly the F-factor did!
My Chemistry prof told stories every class about him playing chemistry pranks, like one time dropping 10 lbs of sodium off one of the Ohio State campus bridges into the river and immediately observing a whoosh of 30 ft flames into the air, then running from the campus police. It helped me to understand that Na is strongly cationic and loves to react!
