NASA picture of the day today is a real 🏴󠁧󠁢󠁳󠁣󠁴󠁿beauty! This is a composite image of the ~5000yo Callanish Stones on the Isle of Lewis. The amazing Giuseppe Petricca has only gone and photographed the Sun at noon there, every few days, for a whole year. #Dedication 🔭🧪👌 ℹ️: science.nasa.gov/image-articl...
The imposing Callanish Stones stand talk with their shadows spanning out across the glass.  It's a super clear sky, but looks cold. Above the central stone is a strange figure-of-8 shape of dots.  This is the location of the Sun, at noon, on various different days across the year.

Almost 70% of national polls in 2024 were weighted on party affiliation or past vote. This kind of political weighting is controversial. But evidence shows it has made polls modestly more accurate. New report: how it works, how we do it and its limits: www.pewresearch.org/methods/2026...

This report explains how political weighting works, how Pew Research Center does it, and some of its limitations.

Most people will remember him for his movies, but my favorite Tim Curry performance might actually be the Abhorsen trilogy by @garthnix.bsky.social. His narration on the audiobooks elevated what was already an incredible series of books.

One of my important roles as a senior academic: telling/reminding super-smart junior people that (1) they may soon have the novel experience of not being the smartest one in the room; (2) when they *are* the smartest one in the room, they should still try not to be jerks

For the first time, a majority of adults under 30 say they’re more concerned than excited about #AI. Their concern is now on par with those in their 30s and 40s, and those 65 and up.

If you post survey data, news articles, etc. without a link back to the source whenever possible, you are weakening the informational chain of custody and making it harder for other people to confirm that they're seeing accurate information. This holds even if you're mad at whatever it is.
