This is spot on. The year after I stopped playing Little League, my former team won the US championship. The parents were nuts, and I’m so glad I got out when I did. Every parent was convinced their kid would go pro. One played played for the Yakima Bears for one year.

NSF has reduced the research budget for all atmospheric, ocean, and earth sciences by ~80%. 80%! A lot of us will not be conducting new research or training new students for the foreseeable future.

In my radiative transfer class in grad school, there were a handful times when I remember thinking “that’s just goofy. Nope, not learning it” Teaching one of those tomorrow.

this. do you know how embarassing it was to watch a sporting event on tv in a room where you're the only trans person? and that "kamala is for they them ad" comes on and everyone knows it's about you? and they all just kinda laugh nervously or look uncomfortable? because it wears on us.

I don't think people really understand the psychic impact of knowing that multiple times a day every day your friends, family, coworkers, neighbors, and everyone who could ever have any power over you is being flooded with agitprop designed to make them hate you

One of the more insidious phrasings I've seen with the Dems/trans rights discourse lately is the idea that trans people are being greedy and demanding a "maximalist" approach to trans rights. No, you cannot call the state of rights American trans people had as recently as 2023 "maximalist," sorry.

it's so exhausting to have nobody talking about in the media or otherwise about how much harder it has gotten to exist in society as a trans person. i gotta worry about peeing at the airport. i know people who won't go get their drivers license updated and you're joking about pronouns

I don’t care what side you are on… if you see a random person on the internet post a political position you disagree with and then decide to take the time to look up and publicly post information on their home, it’s time to stop, touch grass, and find a more productive outlet for your frustration.

Deadly fact: The smaller the particle, the easier it is to get across cellular barriers and do damage. PM2.5 (particulate matter < 2.5 micron) is fhe most hazardous. ISM dust is ~< 0.1 micron, and not something I would like to breathe in in real life.

Where are my live Swift updates?!?!? No, not Taylor! (Also, this mission patch is quite something) science.nasa.gov/blogs/swift/...
Swift reboost mission path. The image has a black circle outline with a blur interior. A drawing of the Swift telescope and spacecraft is drawn in white and blue in the top left with a swift bird drawn on the open mirror cover. A large Pegasus is drawn from the bottom with head near the spacecraft and wings extending beyond the black patch border. The Pegasus is white and blue with red eyes and blue hoofs. A cowpoke with a white shirt, blue pants, blue boots, and a white hat is riding the Pegasus and lassoing the spacecraft.
