I read it first as a contemporary list. :(
Thanks, John! It was a fun presentation to give, too
Unfortunately
My pedagogy matured during the golden age of blogging. I'm incredibly thankful to @rhettallain.bsky.social for being central to that work. Congratulations on your Richtmyer Memorial Lecture Award! #AAPTWM26

Same! Though privacy and feedback were my main motivators, grades online only is also more convenient. I use a spreadsheet to sum assessment scores then import the results into the LMS.
Jim says awwww, you’re a good person. I agree!
Two first-time physics teaching conference presenters. Jim Perry on left and Megan Hayes-Golding on right. The slide behind them reads "Live Action Problems".
Jim Perry and I just finished presenting “Live Action Problems” at #AAPTWM26. We both very much appreciate the community for being incredibly welcoming to us as first time presenters. #ITeachPhysics

What a view!
I’ll be at AAPT after lunch. Looking forward to meeting you in person!
We just did a bunch like this in my A2 classes!
Here’s the list of MA towns with flu on their hands: youtu.be/FhC76xAq7oE?...
Lots sick over here, too, a few towns over. So many students and faculty sick.
Screenshot from Gemini. The prompt, visible at the top, reads "Generate a word problem that involves finding the vertex of the graph of a quadratic equation. The context should be related to areas and perimeters." The response is a drawing of a shed with a fenced yard adjacent. The text on the image reads "She have bat fot asible sidl sine garden x 20 + y = 120 m" then "A=xy" then "Express A = as a function of x maximum possible area of"
Say what, Gemini?
Wait, that's so cool! Am I seeing correctly that the lever uses mechanical advantage to amplify what's likely a pretty small force sensor reading?

Happy Hanukkah from our family to yours!
Photo of two force sensors interacting with a cardboard box. The computer next to this setup displays the live force sensors readings.
Graphical Analysis has a "meters" display mode where a live sensor value is displayed. Is this what you're looking for?
Thank you for this, I just looked them up and realized how inexpensive they are. Got one on order for next year!
Hard agree.
I forgot to get the second in my shingles series, I recently got my 2nd first shingles shot -- and would do it again to avoid the illness!
A glass apparatus filled with blue fluid. On the left appears to be a test tube, next to it a thin spiral, then a vertical tube with two wide spots shaped like spheres, and finally an angled thin tube. All four are connected by a common tube across the bottom.
Man, I love teaching fluids. #ITeachPhysics
This pic led to a great discussion that included "why does this problem seem to be trying to get you to draw the wrong conclusion?"

It’s so cold today that there are teenagers wearing coats.
Photo of a hand drawn symbol in red. Text beneath it says “this sine meens no.”
Here’s the first page.
I feel bait and switched. #ITeachMath ♾️

Vertical photo of a canal in Utrecht, Netherlands. In the foreground is a planter full of red and white flowers, and in the background is a canal lined with traditional Dutch three and four story buildings.
The struggle is real! 4/€1,00 grocery store croissants in Netherlands this summer confused me for a solid minute.
I think that’s the right answer!
I think all three of us are annoyed with ourselves for not remembering that the . vs , convention is different in other parts of the world.
Aha, this feels like the correct answer! Unambiguous…thank you
What’s funny is the three of us recently chuckled over potential confusion when writing dates.
Next time, I think I’ll put a note below the table to say I’m using the US convention.
Do authors of STEM papers say which decimal/thousands separator convention they’re using? Or is the reader supposed to pick it up from context?
You got it! That’s exactly what happened! Lookup table I provided on the test listed the density of water as 1.000 g/cm^3. Two stus read it as one thousand but I meant one.
We all had an “of course!” moment because we all know this int’l diff and yet made the mistake.
