My father attended Engineering School in the late 1960s and has a story of a "scene" during a Calculus II lecture...
A young co-ed (major unknown) had interrupted the lecturer asking, in a snotty way, "Why do we need to learn this?".
The professor paused, and took the time to explain how there are certain engineering problems that require the techniques he was lecturing on.
The young girl then, arrogantly, came back saying "...but why do we have to learn this?!?"
The Prof, remained calm and then detailed out on the blackboard an example problem that directly related between engineering problem-solving, and the particular theory he was trying to lecture on. He finished his problem and the whole lecture hall sat there silent... most students grasped the approach that was used... but the young co-ed still was unsatisfied and blurted out "that still doesn't explain why we need to know this".
The lecturer facing the class, turned and put down the chalk at the bottom of the board, then turned around to face the entire lecture hall and simply says, "It would be wise to point out that not everyone in this class will be graduating with an Engineering Degree... in fact, it is my advice that some of you would be better off MARRYING an Engineer, rather than attending school to attempt to BE and Engineer".
The little twat got all indignant, gathered up her books and stormed out of the lecture hall.
Ah... could you possibly imagine what would happen if some professor said such a truism today?
Ha, Ha, that’s a good one. Yeah, if he said it today it’d be off to the re-education camp.
Apparently she was ahead of her time and would have been better off studying womyn’s math.
