If you are using online whiteboards (like Slides or a paid app) and want a way to view all of them at once (to monitor each group's progress in real time), this video shows how: youtu.be/Rn7zmK24v8I (I promise that the video is very boring, but maybe useful.) #iteachphysics

Version 4.30 of nPlot is live. Adds power law and exponential fits. noragulfa.com/nPlot/nPlot.ht… #iteachphysics

Teaching electricity? Actively explore capacitors and dipoles. Visualize field lines and equipotentials. Follow test charge trajectories. noragulfa.com/efield/efield.… #iteachphysics

The acceleration lab in a hybrid classroom: kids in the classroom with actual spinners, kids online with spinner videos from Aaron Debbink We're all learning! #iteachphysics

#iteachphysics @gatkri Hybrid since Sept. 1... Have in-school kids join the Zoom. Use breakout groups a lot, with a mix of in-school and at-home, to keep the at-homers engaged. Call on the at-homers to answer 80% or so of the socratic questions you pose.

I have a new goal. I want to teach every class with the same enthusiasm Nandi Bushell brings to her drum kit. youtube.com/watch?v=Mlm0qw… #iteachphysics #smilesinapandemic

nPlot has been updated. Large and small numbers are now automatically plotted using scientific notation. Useful for plotting the PhET gravity simulation?

#iteachphysics @fnochese nPlot (noragulfa.com/nPlot/nPlot.ht…) the free graphing and fitting program for students and teachers has two new fits: to a square root function and to "no relation". New features continue to be Frank's fault.

#iteachphysics Version 2.0 of E-Field Explorer noragulfa.com/efield/efield.… introduces Sandbox mode. Lets students explore arbitrary charge configurations. Free to all, without ads, cookies, tracking, etc. (There may be tiny amounts of snark.)

Friday was parent/teacher conferences. But it was a half day, so...new feature in nPlot: subscripts! #iteachphysics

New features in #nPlot. You can position the fitting results and other text on the graph. There's spiffy arrows too! The Tangent Finder can be restricted to only where you have data points. And the exponential fit finally has a baseline. noragulfa.com #iteachphysics

Teaching momentum again, and still bothered by no named unit. There are 19 SI units named for men, none for women. It is time for the noether! Equal to 1 kg m/s and named in honor of Emy Noether and her theorem. Hey #iteachphysics, how do we make this happen?

In class today: Me: "1 noether = 1 kg m/s" Student: "If I use noethers in college, will they think I am crazy?" Me: "Yes." Student: "Good." #iteachphysics #noethers

Teaching about oscillators and suddenly need my students to plot five force vs. distance graphs at once. So nPlot now supports 5 curves instead of 3. Free and available to all! noragulfa.com #iteachphysics #nPlot

V5.7 of nPlot is out. Basics are the same, but now you can edit annotations, and saving a graph saves all curves plus annotation as a single file. Plus, it almost has a user manual. noragulfa.com (open to all, no ads, no tracking!) #iteachphysics
