Pluto has a heart, maybe the other big TNOs all have features too? Like this [thing]'s face. Maybe Haumea has one huge bicep.

Planetary scientists - we have a continual lament that goes like, waaah we have too many meetings how can we work and put in so many abstracts! Here's a solution! Choose a different meeting!

Dr. Adeene Denton @spacewhalerider.com · 18h

It's really disheartening to try to talk to colleagues about boycotting a conference that removed all its records of abstracts pertaining to DEI, only for the response to largely be "I don't want to go, but..." But what??? Each of us has agency! You can choose not to go!

reading "the nemesis affair" by the first author of this paper david raup at a key stage in graduate school was really impactful on the way that I think about how science works -- plus it's just a great book

giving my students a fun lecture on what did in the dinosaurs tomorrow which means it's time to refresh myself on all the fun ideas which were super super wrong

really want to hear the PA GOP explain how this problem could be fixed with additional efficiency measures, futzing around with management, and austerity

got to see DEVO & the B-52s a couple nights ago as a belated birthday present from my fiancée -- really, really great.

do you think the secretary of defense has to go to the liquor store at 11:48 AM himself during shutdowns? or is that particular aid deemed critical?

I am indeed picking our extra credit movies this semester to span a range of answers to the two classic film criticism questions: "is this movie secretly about Gender?" and "how often is there a claymation gory jumpscare?"

kind of shocking how this movie looks good both as a 4K restoration at a theater and also as seen on literal old tape

I'm giving out an extra credit assignment this week for my gen-ed "Life in the Universe" class to watch "The Thing". the exciting thing about the thing is that the thing is available (the whole thing) on the internet archive as a scanned-in VHS, scan-lines and screwy audio and all -- it's amazing.

the fact that so many people frame autism as “a problem that needs to be solved” is a constant reminder that being “not normal” isn’t acceptable to a large amount of the world. it’s the same reason there’s a trans panic right now too. they think people are defective

so my spouse is part of a weirdly intense but mostly benign men's workout group that meets at like, 5:30am outside every day, even in winter. they do a lot of burpees and lugging cinder blocks up hills and stuff.
they take turns leading the workouts and tomorrow is his turn. I asked what he was planning. he handed me a sheet of William Carlos William poems from a large stack he'd printed.
I said "what" and he explained, helpfully, "it's a William Carlos William themed workout." I asked what inspired it and he said "l've been planning this for months."

it was a smash hit.
a dozen guys showed up (more than usual). spouse brought a red wheelbarrow and they took turns bringing cinder blocks up the hill with it. then they broke up in teams and did a relay with an "icebox" (cooler filled with 40lbs of ice). at the end he opened the cooler to reveal it was full of beach plum lacroix and all the guys cheered. they drank sparkling water as he read 'approach of winter' out loud.
he was home by 6:30am.

getting back into just a little bit of research after a month of teaching: what a treat. there's a kind of strange and pleasant dissonance from telling your students "this is what the solar system is like and how it works" and getting back to your office and thinking "yeah but was any of that true?"

Hayabusa2’s final target is really, really small. And really, really fast. That presents both a challenge for a touchdown attempt and an opportunity for asteroid researchers.

Hayabusa2’s Final Target is 3 Times Smaller Than We Thought - Eos

It also spins twice as fast as previous estimates suggested. A spacecraft touchdown will be challenging, but not impossible.
