As a math professor, I'm amazed that our students learn to answer exam questions about damped, driven systems without internalizing anything about the idea. Now, our pandemic is a damped, driven system and no one gets it.
I love multiple choice. I aced Regents exams in high school by borrowing old study guides to memorize the missing half of the corpus. I recently had a great time taking the Triplebyte quiz inebriated. So I was gearing up to trying to keep up with this guy.
Question 1, bam! B. Needs infinite memory, regularity is a finiteness condition. I read it first because it was shortest, didn't even look at the other choices. Show me question 2! What? He's still talking?
I understand the pumping lemma, but here it's a technical way to solve the problem under general anesthesia. I guess math isn't alone at failing to teach what things really mean.
I never got to question 2, I got bored.

- areyousure 6y agoRegarding question 1: what if L is a very simple regular language? For example, if L is the empty language (which is regular), then option B is again the empty language (and thus regular). While B is the best choice among those provided, the question is poorly written.
