Learning the skills to solve physics problems, solving physics problems, and presenting the solutions to physics problems are not the same mental activity.
We focus too much on the last point thinking the first two will arrive naturally.

If you want to know why some people find it easier to learn cooking, carpentry, auto mechanics, music, or sports than learning physics…
Look no further than how we teach physics differently than how we teach cooking, carpentry, auto mechanics, music, or sports.

U.K. might lose a prime minister because a guy who worked for him knew another guy who hung out with Epstein. Meanwhile the U.S. opposition party is telling our President, who was Epstein's best friend, that his secret police should get better training so their public street murders look less messy.

Absolutely. You can’t begin to solve a physics problem without a literacy that is both common and domain specific. Fluency is too often ignored. #edusky

There is humility in using a checklist, especially when learning. An admission that memory and skills are fallible, and excellence is not about brilliance in the moment, but about showing up prepared every time. #EduSky

Canadian Prime Minister Mark Carney's speech at Davos is quite brilliant. Without vitriol or exaggeration, he outlines the harsh new world that Trump is leading us all toward. Here's the full text; much recommended: globalnews.ca/news/1162087...

Yes. The first thing I did upon retiring from teaching was to buy a new stereo. The sound of music has returned triumphantly to our home.
"I used to listen to music all the time," @chatterton.bsky.social laments. "Now I fill every available moment with the sound of people talking." Compulsively listening to podcasts shows "just how limiting too much information can be," Williams argues:
The Podcast ‘Productivity’ Trap
Maybe don’t fill every available silence with the sound of people talking.

Not that anybody asked, but If you accumulated all the flora, fauna, and metal that your True Love gives you each day in the “Twelve Days of Christmas” song, you would own 12 Trees, 40 Gold Rings, 140 Humans, and 185 Birds of 6 different species.
