I research differential geometry-informed optimal experimental design

I forget where I originally saw this, but it's one of my absolute favorite memes. #MathSky #iTeachMath #MathMemes #ScienceMemes

This meme probably best describes my research life for the past three months. #MathSky #Science #MATLAB

I know @miniminuteman.bsky.social does a lot of conspiracy theory debunking, but I've got one that's irrefutable. Milo is actually the fictional character Casey Jones played by Elias Koteas brought to reality by ancient alien-druid magic. #conspiracytheory

People of #sciart I am desperately trying to find the original artist who made this masterpiece, but I find my forensic art skills are lacking a bit. Can anyone track down who the original artist of this is?

I really want to start an archive of all the times Google's AI overview missed the context entirely, maybe get something going like #GoogleMissedTheContext. To those curious, I was wondering how to do pencil smudging on the reMarkable drawing tablet. You missed the mark, Google 🤦. #sciart #art #ai

I took this a while ago at the Hirshfeld-Dowd Observatory at UMass Dartmouth with my daughter. I wanted to post this tonight because of something about wrapping presents for her and Santa flying through the sky and the stars being visible and… and… whatever here's the moon 😝

Here's some art I made for my website. It's my first time really being expressive, using math or otherwise, so please let me know what you all think! I wrote a short, qualitative description of the underlying mathematics; you can read more about it here: wp.me/PgcDuC-2O

Give me a single screenshot from a video game that immediately makes you hear the soundtrack in your head.

Hot Take: I can't say how much I really dislike AI art (or at least how it pervasively permeates the Internet). I was Googling something related to Isaac Newton and one of the featured images was this. Granted I can't be 100% in saying it's AI, but it reeks of that "AI-style", has no… (1/5)

I would have never in a million years anticipated this to be the first/best comment to this #Reddit post concerning a random #ecology question that I also had. 🫤

If anyone in the fields of #ecology, #zoology, #MarineEcology wants to chime in about a better answer 😅, I'd greatly appreciate it! 🌍 🧪 🌳

I was watching a Neil Degrasse Tyson video that referenced the Dunning-Kruger and showed this graph on the screen. It was about four years ago when I learned that the Dunning-Kruger effect is way different and way more technical that what we colloquially identify it as. (See comment ref) #Science
