I'm not super active on LinkedIn, but I'd be interested. I just searched the group over there and requested to join!

The longer I teach physics, the less interested I become in teaching about energy. It seems like every time we use the idea of energy to try and explain something, we're actually hiding the underlying mechanism which causes that thing to happen. #iteachphysics 🎢

Today was Day 1 for us, and let me tell you, it felt good to be in the classroom. Teaching rocks 🎢

That agreement between measured height and reported height is nice. There must be something to this physics thing, huh?

graph of position vs time, time form 0 to 70s, showing steady upward slope, graph of velocity showing increase from 0 to a steady level of 2.6 m/s, followed by a drop to zero. then acceleration graph with a short part at 0.5 followed by a long period of zero, then short part of -0.5.

Did I collect accelerometer data using @phyphox.org riding the Washington Monument elevator today? Of course! The velocity (2.6 m/s) is a little faster than most elevators. Acceleration is lower than most. Max position of 153 m compares well with 500 ft height of observation level. #ITeachPhysics

For you we'll say it was on Mars, g ≈ 3.7 N/kg

It's summer. That amount of effort is reserved for the school year

Post from "The Rundown" July 18 at 5:30 PM · DuckDuckGo has introduced a new feature allowing users to filter out AI-generated images from search results, addressing growing concerns over synthetic content overwhelming authentic visuals online. The filter can be activated through a dropdown in the Images tab, search settings, or by using a dedicated AI-free domain: noai.duckduckgo.com. The system relies on curated blocklists, including uBlockOrigin’s Huge AI Blocklist, to detect and suppress AI-generated imagery. While not perfect, it significantly reduces synthetic content visibility. This move sets DuckDuckGo apart from competitors like Google and Bing by giving users direct control over their exposure to AI-generated material. Source: TechCrunch

DuckDuckGo has added a feature to filter out AI images from search results.

I'm surprised the velocity and position curves are so smooth, considering how noisy the acceleration graph is. I wonder if they do some smoothing when integrating?

If I'm computing with measurements, calculations from measurements, or numbers from problems that stand in for one of these, then I use = with sig fig rules. This truly is equality, as best we can measure it.

I use ≈ if I'm doing a back of the envelope calculation where I'm estimating input values.

How did you measure acceleration? Did you swing around an accelerometer?

The other benefit to these is that they work with both wired and wireless force probes

I don't know of one. I'm guessing they're expensive, in part, because they don't have other commercial applications

I just want to know what @pascoscientific.bsky.social was thinking when they named this product. The word "oscillator" is right there #iteachphysics 🎢

I'd consider it! Recently, though, I don't find myself reaching to Desmos as a tool. I think my post-pandemic teaching preferences are leaning more and more analog. Sometimes I wonder about teaching an old-school physics class with no screens all year.

And here's the link to Part 2, where we made a few animations. At the time, Desmos did not have the ability to do iterative loops like While Loops, but it does now. So the methods in this video still work, but more sophisticated methods are now possible.

Thank you for turning me on to the air capacitor! Here's the one my colleague built: youtu.be/kwXCZE0ccgg

At my first school, I taught three (but all physics preps). Now it's two.

While I like the driving philosophy of collaboration and data sharing, three to four preps and multiple PLCs sounds like a recipe for overwork and burnout.

Parallel circuits should be called current adders instead of current dividers #iteachphysics

Lots of great AMTA curricular resources on their website for pretty much all physics topics. I'd build from the ones you aren't using now.
