I'd love to hear more about your story!

This is my perspective as well. I'm not confident I could use math to make myself a lot of money, more that I can use the style of thinking to pin down how my experiences and actions effect my habits for example.

Alienating students is a real problem. I think supplemental math training can help, e.g. recitations on real analysis alongside a probability course.

Good point. Was it mostly just theory? Or did you get a chance to implement anything in code or an actual machine?

I'm a big fan of the Soviet-era books, though they often require a degree of independence to fully appreciate. Perhaps schools should focus more on developing students' ability to self-teach.

Thank you for a great response! I agree with you on communication-styles. Math education could definitely use some more clarity in exposition of procedures and notation. With regards to reason 3, this is true for me at least! Much of my lea

Thank you for this much needed perspective. I do agree that tools shouldn't take precedence over the problems they're used to solve (like you say, unless you're a mathematician). If you're willing to spare more time, whi

Definitely agree! When reviewing papers I've come across bad (incorrect) mathematics and unnecessary posturing. I guess I'm seeing controls for what it is at it's best. Any thoughts on geometric control theory (in the vein of

Great point! I'm thinking of analysis courses that begin with measure theory, also differential geometry and calculus on manifolds (though those definitely can be undergraduate). Some graduate level math-in-engineering topics are thing

How come you think discrete math is too hard to teach? Calculus has definitely been useful to me for understanding how rates and totals relate to eachother, which shows up everywhere -- and also understanding volumes and shapes! It's a

Thanks for your response! I do actually suffer from ADHD, though I'm (and was) intentionally unmedicated. Really had to develop my discipline and internal motivation before I could give a good try to math, so I definitely get what you
