Tell me how much you know about first order differential equations because the issue is illustrated with a simple math problem, the same math that keeps reactors safe and makes nuclear bombs explode.
Wow, you’re really good at missing the point. And I’m not impressed by your reference to “first order differential equations”. I took three semesters of calculus in college, but it isn’t relevant to a discussion over whether face diapers are or are not effective or necessary.
