Whenever I’m down I watch this video of Dolly Parton joining Kenny Rogers during their joint 1985 tour. The crowd pop when she comes onstage mid-song is unlike anything I’ve ever heard.

Only 1% of proton's mass is those 3 quarks. The binding energy creates a lavalamp of gluons and quark-antiquark pairs. See also Prof Aleksey Cherman's public lecture: Why Particles Don't Exist www.youtube.com/watch?v=SBAI...
In textbooks, protons and neutrons are bundles of three quarks. In the real world, it's turning out to be much more complicated than that.🧪⚛️ physicsworld.com/a/protons-an...
Gail - Are you suggesting that they can just put something in a movie that isn't true? If that's your attitude, then I must say - Good Day, Madam. I said Good Day!
Call me a cynic, but I’m not sure that Rodney Dangerfield actually performed the Triple Lindy high dive in that one movie with the kid from Christine.
There's also the earlier version: [Edward G. Robinson as Odysseus] Now listen you muggs, we're going rowing past the Sirens, see. But you all are putting this wax in your ears, see, so you can't hear nuttin'. I want you muggs to tie me up, so I can hear them, but don't screwy in the head, see!
[James Stewart as Odysseus] now listen here, Agamemnon, I'm going home, y'see. You keep your fancy armour, I'm getting off this crummy ol' beach. [Spotting the Cyclops] now here's a curious fella, he's only got one peeper
Saturday reflections. I'm often asked which superheroes are the most scientifically plausible. Here are my top five: www.youtube.com/watch?v=6inY...

This is what kills me over the current attacks on STEM funding for universities. The only way to train a research scientist is to have them do scientific research. You can read every book on basketball, but you won't be able to make a layup until you get on the court.
much of what i learned in college is now easily accessible online, but the essential critical thinking skills it taught me are not. you get those by doing the work, not having it done for you.
Blocking you would be too easy, Mr. Bluesky.
You people are maniacs. But I might have to frame this one

A black hole for Omega Centauri! Astronomers have finally found their first stellar mass black hole in the ridiculously spectacular star cluster… but there could be *ten thousand* more still waiting to be discovered. badastronomy.beehiiv.com/p/a-black-ho... 🔭 🧪

Just saw The Odyssey. Truly Epic. I have no words - they should have sent a poet. All seriousness aside, it was one of the most amazing films I've seen. There's an IMAX theater in MN, and this will definitely warrant the trip for a rewatch. I'd keep my eye on that Nolan kid - I think he's hot.
Agreed. I'd buy turning humans into animals, but the cyclops is just fantasy.

It's a tie between these two, but I think I give the edge to: Tom Sawyer, you tricked me. This is less fun than previously indicated. Let this corny slice of Americana be your tomb for all eternity.

2nd July 1863. Battle of Gettysburg. For perhaps the only time in the entire war the Confederates seem to be winning. Dan Sickles, commander III Corps, is ordered hold on Cemetery Ridge. For reasons unknown he advances. Broken, his men begin to flee. This is the moment on which the war depends /1

With Big Data comes big sorting problems. UMN Prof. Lucy Fortson and Oxford's Chris Linott founded the Zooniverse, where citizen scientists help identify images from astronomy to medicine to wildlife. Started 20 years ago, they have reached a milestone: twin-cities.umn.edu/news-events/...

It’s Roger Livesey’s birthday. The Life & Death of Col. Blimp is a favourite film & it’s largely due to the brilliant performances of Livesey and Anton Walbrook as lifelong friends from warring countries. This scene is sadly all too prescient about our current situation: youtu.be/vb2AlCaY_gk?...
