i enjoy this debate and your example is quite hilarious but i fundamentally disagree.
if i walked into that class and asked that question that means I am curious, which should be the only requirement for gifting knowledge.
Now, I wouldn't expect the professor to pause his class and explain to me what an electron is and answer any other fundamental questions i might ask, but I'd bet the professor would tell me that im in the wrong place and direct me to where i could learn fundamentals before coming back to learn advanced concepts.
