Writing that as a β€œpractice problem” might be a little out there, but I think your idea of leaving it as an exploration at the end of the chapter is a good one. It would be fun!

I also like the todonotes packages for this purpose, but that’s not as efficient as your solution.

The obvious solution is to wait nonlinearly.

If only we could put these on our CVs.

I love giving this as a homework problem. It’s a nice derivation.

I got a chuckle out of Figure 5!

It sounds like a bug!

Replacing the real numbers sounds like an Archimedean task.

Sorry…

The humanities, like the sciences, provide valuable tools for engaging and analyzing the world in which we live. To call for their separation is a disservice to our students and is yet another capitulation that will only invite further demands from this administration.

I went through that airport so often in grad school yet never took advantage of this. Unfortunate.

Sadly, it’s never worked this way for the Mariners.

Absolutely!

Either Euclid is still alive or he was born, wrote the Elements, and died in a single year. Either way, impressive!

Doing these conversions was a fun way to pass the time whenever I drove the Alcan.

Oh, for sure! I just spend a little too much time there occasionally.

Goal: increase productivity.
Action: include new productivity tools into workflow.
Result: decreased productivity.

I will never learn.

That’s usually what I did. LaTeXiT also has support for macOS services, so you could type LaTeX code in your email, right-click it and then transform it into an appropriate rendered version. At least I think that was what was supposed to happen, as I don’t remember getting that to work on my Mac.

I’ve had limited success on a Mac with LaTeXiT. Sometimes the rendered math doesn’t display where I expect it to however.

I very recently started using Emacs, mu4e and org-msg for exactly this purpose with good results but the setup was by no means easy (at least for me!).

I finally got #emacs set up with mu4e and org-msg. Hopefully this will make answering questions about math homework by email a lot more manageable this fall. #MathSky

I read it as β€œKongtent” and got really hopeful you were talking about Donkey Kong Country for a bit.

That sounds like what happens to work I’m too demoralized to do/grade so it goes to the bottom of the pile. β€œI’m sorry, I haven’t graded your test yet. I disappoofed it.”

The global agenda/capture bindings are a great idea!

This sounds reasonable to me. If it was someone else’s work they didn’t cite and not yours, would your feedback be any different?

I’ve been using github.com/bbatsov/prel... for about a year now, and I’ve found it to be a sensible starting point for getting back into Emacs. Before this I was primarily using Sublime Text.

I’ve only used subcaption for this purpose. It’s alright, but I don’t do anything too fancy with it either.

We could try using the binomial series for a similar approach. Assuming I can do math today, I get
sqrt(221)-14=1-2/15-…
sqrt(3)/2=1-2/16-…
