I love nature, math, and finding out how stuff works. I use math to understand how nature works, and sometimes find ways to make that understanding useful (I hope). A. Professor @ Johns Hopkins working on water and the critical zone

@hankgreen.bsky.social I'm a big fan, but you're not quite right in your latest short. You said a cloud is significantly heavier than the atmosphere. It's counter-intuitive, but this is not true.

My guess: we will end up padding budgets with more institution-required line items like “facility use fees” to cover the shortfall. The bigger problem might be the cut to overall NSF funding

Anyone want to get on zoom and be accountability buddies this afternoon? Tell me what you have been avoiding working on and I'll do the same and we can knock them out together!

Haven't posted on here much but just got a bunch of new followers. Hi! Also, is there a name for the feeling when a bunch of people in a room suddenly start looking in your direction and you wonder if you just sprouted an extra head?

Tragically, Hari Rajaram died last Thursday at his home in Baltimore. Hari was a well-known and beloved part of the earth science community, and he will be sorely missed

I just got asked to review a big, tough paper by someone I really respect. I plan on going deep and trying to really get to grips with the math and the ideas they represent. Here's my question: if I livestream myself doing that, would you watch and read along with me? 🤓 (there's a preprint)

This Turing-like pattern shows up in the grass at my in-laws place in North Carolina every Thanksgiving. What do you think causes it?

Hi, I am 43 and have advanced degrees and I simply cannot spell the word "privilege" correctly the first time. At this point I'm resigned to simply relying on a spell-checker for the rest of my life. God help me if I ever have to hand-write a DEI statement
