If your only value in the classroom is knowing more than the students, you don’t understand pedagogy

Our new dehumidifier has a setting to use grains (of water) per pound (of dry air) instead of % relative humidity. Had to look it up. 7000 grains in a pound.

It is impossible for an AI to complete the problems when it doesn't have enough context, and this does not depend on the type of AI. The context was given in the lectures, demonstrations, and homework. You can see the results clearly: 2025 no AI, clean distribution 2026 AI used, split distribution

Georgia Power is announcing a rate decrease this summer. They must really be worried about losing the third seat on the Public Service Commission in November.

The Soviet Union did that, and it worked out badly.

I collect pearls of wisdom from teachers and at lunch today thought it'd be fun to get them edited down to a little book of wisdom style with a prompt for reflection. This is for my own use really, to try and stop me from going stale but it's here: www.jrowing.com/resources/pe... #ITeachPhysics

I’ve said it before and will say it a few more times. When Trump 2.0 came for accreditation I knew we had crossed into a different era of white reclamation. Precise, focused, stealth. Anyway, you probably don’t want these reforms.

So I get to work a real probability problem. If the continuous glucose sensor fails 1/4 of the time, how many do I need to ensure, to some degree of certainty, that I have enough? Say, supposed to last 15 days, want to be reasonably sure I have enough on hand for a month.

Jupiter wants in on the fun.

Playing with new phone.

Slow motion shot of when baseballs collide during warmup (via r/baseball)

Our governor (GA) is joining in, calling a special session for redistricting. Would not be in effect for 2026. This after deciding that Dem counties must have nonpartisan elections (except sheriff and coroner). The steal is on.

What does it take to make #PhET's interactive sims accessible? There's no text alternative that replicates the experience of discovering Ohm's Law by building a circuit. Learn more about our accessibility work:

Ran into something called tychos.org which in some ways is similar to #vpython but only in 2d. Anyone familiar with it?

Cool analysis of falling birds.

Raise your hand if you used Science Citation Index. Talked to a young colleague who never heard of it.

Good day for this to come by. Reposting as required.

Two photos. Same room. Same flags. Same astronauts. In one, the President stands with them, smiling, centered, human. In the other, the President sits scowling, rambling, diminished. Four astronauts. Two presidents. And the faces tell you everything.

Delayed on the way into the Science Center. First saw the 22 degree halo (just above the tree at the bottom), took lots of pictures. Looked straight up and there was the circumzenithal arc (towards the top). Gotta love those ice crystals. This was shortly after a heavy band of rain came through.

A broken bone heals faster when subject to ~50 Hz vibrations. You know who vibrates at 50 Hz? 1/7 ⚛️🧪

I wonder if Hegseth believes in latrines. They seem a bit woke and unmanly to me.

I hope he wins and helps carry other state-wide candidates.

Not backing down in his campaign.

I'm telling you, the solution to many problems in education is to hire school librarians (at a liveable wage, with administrative support, and adequate resources). Your students don't need an LLM, they need a librarian.

Ho hum, the session on "academic integrity and ai" was not about that, but rather a push to let students use ai in certain ways. no sense that struggle is part of learning, that making your own study guide is part of organizing the material in your mind, that brainstorming topics important.

The Republicans will not do a thing. They are okay with having an insane king. Useless losers.

A bill passed the Georgia senate to put us on Atlantic time (not Eastern) and stay on standard time all year. Makes for interesting time differences with our neighbors.

Is anyone else having trouble buying LabVIEW these days? It's been a nightmare.

What happens if an anti-proton meets a neutron? Is there any barrier (QCD is foreign to me)?

Drat, I missed the spring equilux. #iTeachPhysics #refraction #optics

Ban daylight saving time.

Clouds. Of course.

Our students came up with a creative solution to measure a force with a smartphone and phyphox.

that they have kept their relationship intensely private to the point that this is how we find out is probably the best sign they might actually make it anyway, rules are rules, here is the exact moment she fell in love

A couple of students used the No unit for momentum on the exam! #iTeachPhysics #Noether #momentumUnits

Halo there.

There is no sense in which a chatbot can "help" with your schoolwork by making it easier; if it is easier, it is less useful for actual learning (effortful practice is HOW WE LEARN) and therefore the chatbot has not helped, but has only hindered.

Got another exercise set published in #PICUP. The students run through various scenarios to save the Earth from an asteroid, using glowscript coding. Includes momentum, constant force, and energy in the different scenarios. www.compadre.org/PICUP/exerci... #iTeachPhysics #glowscript #vpython

Yes, you can buy fancy apparatus, but I prefer this way. Good discussion-starter for the first day of Physics I. youtu.be/TMTKjIDCvOs Alt-text: Person tosses a ball straight up and catches it, then does the same arm motion while walking and still catches the ball. Done again while running.

New momentum transfer video just dropped 😊 #iTeachPhysics #Science 🧪

What can happen when you don't cave in.

When the higher education sector is organized, we have the power to stop the Trump administration's campaigns against American universities We are proud of our members and allies at UCLA who successfully blocked Trump from extracting $1.2 billion from UCLA over alleged civil rights violations.

Okay, so yesterday I saw a video in which some A"I" was having trouble counting. I just realized that in assigning homework for an intro lab, I skipped "3". No wonder I'm confused about what I've graded. #iTeach

Turns out those tire pressure lights also turn on when the pressure is too high. Which is why it kept turning on after driving for a while. #iTeachPhysics

Ghislaine Maxwell, a convicted child sex trafficker, gets gardening time, sports, therapy dogs, and spa products in prison. Migrant children in custody are sleeping on concrete floors without enough food or clean water. Our priorities are so fucked.

We have a super easy letter campaign to save NCAR. Takes 30 seconds to yell at your Congress Critters and you’ll can do it every day! @standupforscience.bsky.social fight2win.standupforscience.net/campaign/152...

Strange, FAA seems to have lifted the 10-day restriction on El Paso air space, supposedly put in place because of Mexican drones (for 10 days???). www.newsweek.com/texas-el-pas...

All these cutesy names CBP/ICE come up with for their smash-and-grabs, you know there is something wrong with what they are doing.

Looking at my trinket download, lots of files with names starting with "copy of copy of" or with similar names that will be hard to untangle. I suppose I should work on some vague resemblance of version control.
