Zero Gravity (and Levity)
On that final note, I think it’s time to bring this blog to a close.
Now that I’ve moved on from graduate student to post-doc, my priorities have shifted, and you may have noticed that I haven’t been posting enough to keep this blog respectable. This seems like more of a permanent change in my work habits than a temporary increase in busyness, so I think that now is the right time to close down Gravity and Levity.
It’s been a tremendous amount of fun, and along the way I somehow attracted a sort of dazzlingly intelligent set of readers leaving intelligent comments. So thank you.
I leave unfilled a fairly significant list of half-started blog posts and half-developed ideas for future posts. So if anyone ever wants to invite me to write a guest blog post, I will likely be highly tempted to do so. If for whatever reason you would like to make such an invitation, feel free to say so in the comments and I will respond by email.
Since this post will sit at the top of Gravity and Levity for the forseeable future, I’ll close with a list of my 16 personal favorite blog posts. Thanks again, everyone.
