Small-Scale Question Sunday for May 24, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Yeah, and furthermore for calculus we all still pay the price because limits are honestly only taught as a holdover from that attempt to prove to other math people calculus was legit.

I'm going to defer to the mathematicians on what it is "for", but analysis is one of the major fields of modern mathematics - you need limits to do almost anything rigorous with general real numbers. I agree the only thing you explicitly use limits for in high school maths is making calculus look rigorous, but other very obvious applications in "maths for physicists" are summing infinite series and explaining what it means for numerical algorithms to converge. But limits come up everywhere - in frequentist statistics probability is a limit.
