aif you invite me 如果您邀请我[translate] aIn tandem with this ''bottom-up'' aspect, I really hope to develop students' engagement with the interconnectedness of the sciences. It may not seem particularly exciting to solve some particular quadratic equation (though I think it is!), but when...
$\begingroup$ @abel It's a popular example because it is very easy to solve analytically but demonstrates some of the important theoretical issues with nonlinear ODE, such as blowup in finite time. So it doesn't surprise me that we both came up with it. $\endgroup$ –I...
A few days ago I solved a math problem posted by @Zelly, and that actually was the most fun I've had in quite a while. And I realized that it's also the only active learning I've done in a long time. So give me all your math problems. If you need help on
