Assistant Professor @HarveyMudd studying how planetary systems form and evolve. Past-Chair of the AAS Division on Dynamical Astronomy (he/him).
Joined October 2012
So excited to share that I'm joining the physics dept at Harvey Mudd College. Really feels like a dream job along every axis. I feel so fortunate to be joining such an amazing group of students, in a department with such brilliant, passionate, and downright kind colleagues.

My favorite textbook period. Read it for fun in grad school b/c it was so clear, fascinating and playful, not realizing that Steve was in the engineering dept at Cornell. Got to take the class with him afterward and it remains one of my favorite courses I've taken in any field ❤️.
The third edition of my textbook, Nonlinear Dynamics and Chaos, was published today. You can preview the first 68 pages on Google Books, or take a look at the preface below to see what's new. The main new thing is a chapter on the Kuramoto model! Hope you enjoy it.

🚨Join @hannorein & the rest of us for the first (not 24th!) 2-day virtual REBOUND meeting, aimed to bring REBOUND developers and users together. 1 day of science talks, 1 day of technical/hands-on talks, discussions on REBOUND's future + social events!.

We also renamed the master branch 'main'. If you run into any problems running the code, the easiest fix is just to pip uninstall rebound and reboundx, and pip install them again. Open an issue on github if you run any issues!. 6/6.

If you cloned the repo and have a local REBOUNDx folder, you will no longer be able to merge new changes to REBOUNDx, and won't be able to contribute code to the repo. Just rename your reboundx dir (as a backup for files you've edited) and git clone again. 5/6.

Over time, REBOUNDx accumulated several large unused files in its git history, which made the repo over 100 MB. I have now removed them, making it 13MB, and hope to avoid further large files. If you just ran pip install reboundx to use the package, no action is needed. 4/6.

Many effects you might want to use for planetary dynamics are already implemented: tides, GR, migration, radiation pressure, J2 etc. A full list can be found here:. REBOUNDx also makes it easy to attach parameters to particles in your integrations. 3/6.

REBOUND is an N-body package w/ great integrators for point-source gravity. Rather than add effects like tides etc directly to REBOUND, Hanno & I decided to write a separate library REBOUNDx to hold implementations of common effects & make it easy for others to contribute. 2/6.

🚨 REBOUNDx users:. TLDR: If you used pip install reboundx, everything still works. If you cloned the reboundx repo, you need to delete and clone it again. If you use REBOUND for N-body but wished you could add tides, post-Newtonian corrections etc, this 🧵 is also for you. 1/6.

Thank you ECRs for having the courage to stand up at significant professional cost. That burden should not have fallen on you.
From Guest: When harassers coauthor papers, the community suffers, but nobody is more affected than the Early Career Researchers within those groups. This is how we, the ECRs within the California Planet Search, have tackled the recent authorship debacle.
