Hello --

No new math today, but some updates:

- I'd initially planned to run this blog from June through August. I did it, and it was fun. I took two weeks out to travel and think about what's next and I've decided to do it again. Here comes EarthCalculus Fall Semester edition!
- I'm almost done with a decent draft of an e-book, Conceptual Climate Modeling for All. It cleans up and expands the notes I took at the MAA-NCS Summer Course on conceptual climate modeling. If you'd like to get a free copy in exchange for giving feedback, sign up for the email list on the right-hand side of the page. The email list is updated each night, rather than instantaneously, so you should get email the next day.
- Speaking of the e-book, would you rather have a pdf file, an iBook, a Kindle version...? Why? Feel free to email me or leave a comment.
- Since it's the beginning of the semester, I'll be putting up a more elementary worksheet on inverse functions in the next day or two. We'll go from there.
