My uninformed guess is that it followed the form of β€œPOTUSβ€œ (President of the …) which sounds sexier than β€œPUS”.

Psychology says people who don’t maintain many close friends often learned independence too early I remember being twelve and standing on a chair in our kitchen, trying to reach the top shelf. There was a step stool somewhere, but it felt faster not to look for it. Faster to climb. Faster to stret...

How do the scientists who use these videos account for scale? I assume familiarity with the equipment and critters themselves are probably sufficient most of the time, but I would have expected to see at least a zoom factor captured in the video. Am I missing it? (And thanks for doing this!)

Found an additional graphic that gets even more of these quotes together.

I've kept "I hate myself, I hate clover, and I hate bees" pinned above my desk since I first started studying evolutionary biology as an undergraduate. So relatable to get extremely frustrated with your study system.

Do you find the liminal/crystalline axis useful in approaching the work of, say, e. e. cummings? Or Mez Breeze?

That URL didn’t get embedded as an HTML link, which might have been deliberate. Easy enough to get there via the link in your (the?) bio.

John Varley’s Titan/Wizard/Demon trilogy, if you’re up for your lesbians imagined by a dude in Haight-Ashbury in the 1970s. Loved it when I was 12 years old in West Virginia and didn’t know any lesbians. Tried rereading it recently and… oh dear. But strictly speaking…

a picture of the gorgeous TOYO ST-350 cantilever toolbox in burnt orange - a classic steel toolbox with 1969 pedigree, there's something comforting and friendly in the shade of orange and the cantilever top design, you really feel like it would safely hold any number of tools or art supplies

Never heard of him, not the kind of music I usually listen to, but I'm slowly making my way through what he has on Apple Music and enjoying it quite a bit.

Thanks for the recommendations, and please keep them coming.

If we forbade men from posting without a chaperone, do you think their posts would get better?
