Do students not learn analogies in grade school anymore? The number of first-year college students that ask me what “analogous” means is concerning.

Forced to look for a new apartment right now and the AI “staged” images are killing. They all look alike but nothing like the actual space.

So I’ve been dealing with a foot injury for the past month. Today, I wore a regular shoe for the first time since. Please clap 👏🏻

Hey folks, this hasn’t gotten much attention, but remember those proposed OMB rule changes we all commented on recently? There’s a new attempt to sneak them just for NSF. We have three days to comment. Please don’t sleep on this!

I’ve been dealing with a foot injury so I’ve watched more tv than I’d usually. Last night I caught West Side Story so I thought I’d watch the ‘90s Romeo and Juliet tonight. It was just as devastating as when I saw it as a kid. My god we should be making literature this accessible always

I injured my foot so I’m staying off of it to give it time to heal but wow, am I bad at sitting still.

Well thankfully I grew up on Philly sports and am well accustomed to a team that is built up just to predictably lose

One of my favorite things about science is that it has allowed me to get to know, work with, learn from and teach people from all around the world. When a World Cup comes around, it’s always so fun to cheer along with everyone. 1/2

Look, I grew up on Philly sports. There are deep seated, generational team alliances. But since we’ve moved to NYC, we’ve been trying to figure out a team to emotionally invest in. The Knicks have me sucked in. Plus the Villanova connection? Hate all you want, I’m falling hard

My dog has been interacting more with tv lately, mostly barking at dogs and other animals on screen. It’s an annoying behavior I need to work with him on. Last night, I found Return of the Jedi on and he was locked in. No noise, just observing the Ewoks and light sabers. He seemed really invested.

My focus is shot today. I’ve already called my reps to leave yet another rant on voicemails I’m sure thy don’t listen to. I’ve asked my family in another state to do the same for their useless reps.

My partner is from Iran. This day is something else. What’s striking to me is the dearth of Iranian voices in the coverage today. The diaspora is large - surely the media could find an actual Iranian to talk to

The end of my workday was so jarring. Walked out from giving a talk about my teaching to an active shooting investigation a few blocks off of campus to doomscrolling on the subway to watching someone next to meet annotate a book a poetry

I didn’t have to teach today, so I just went in to do some stuff in the lab. And I got to leave early and take a nap with my dog. I love these liminal days around the holidays

Hey folks, as news of Watson's demise spreads, please don't set aside his weighty legacy of misogyny and racism. He was truly among the worst of us. www.vox.com/2019/1/15/18...
vox.com
DNA scientist James Watson has a remarkably long history of sexist, racist public comments
“People say it would be terrible if we made all girls pretty,” he said in 2003. “I think it would be great.”

I had a migraine start in the middle of teaching yesterday. It’s been years since I had one and it stopped me in my tracks. Timely, I guess, for #MigraineAwarenessWeek

Another much larger dog went after mine at the dog run today. Pinned him a couple times up against the fence I couldn’t see what was happening/get to him. Then the other owner gave me attitude because “oh mine won’t bite”. How the fuck am I supposed to know that? I hate people sometimes 🤬
