@carrillophysics This year I'm trying @gregcjacobs suggestion (https://t.co/KmAPu1oKFA) which I learned about from @BelcherPhys

[Geoff Nunes @gnuphysics]

@msruggerio Well, not quite zero from PA, because I was there!

@joel120193 @ChatPhysics They should ask "Can it be one thing? Or does it need two?" Force always involves two objects: this pushes that. It can never just involve one thing. Energy can be just one thing: this object is hot/high up/moving.

@Prockwell4 Hmm... That circuit actually designed and built by my grad student, Denis Pelekhov, about 30 years ago. I don't think I ever knew the answer to your question. (That's the good thing about good grad students!)

@aronczyk Loved the show on the cheese racks, but surprised none of your experts mentioned demurrage charges... See e.g. the compressed gas business.

@nickbakerqes @kilroi22 Sorry. Written to work on a chromebook. I think that writing stuff like this to work on both a laptop and a phone would require an actual software engineer instead of a high school physics teacher.

[Geoff Nunes @gnuphysics]

@DoonesburyComic you forgot the blood.

[Geoff Nunes @gnuphysics]

Help your students understand that orbiting is falling with a Newton's Cannon simulator. https://t.co/wyj5AQYe5O #iteachphysics

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. https://t.co/XmNSqzkaih (open to all, no ads, no tracking!) #iteachphysics

[Geoff Nunes @gnuphysics]

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! https://t.co/XmNSqzjCsJ #iteachphysics #nPlot

@mrpauller Found notes for dropping a bare egg into a structure on the floor. If a first drop was successful, they try from the next height. Budget: it doesn't matter. Make sure they can "buy" enough to be successful if thoughtful. You are only trying to force them to make choices.

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."

@vincent_grgoire I'm leaning towards noe. We have a few other units with 3 letter symbols (think mol). Avoiding confusion with, say, newtons, seems worth the extra ink.

[Geoff Nunes @gnuphysics]

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?

[Geoff Nunes @gnuphysics]

@maalmeida85 Or maybe abbreviate as a noe. 3.6 noe is less of a mouthful, and at the same time offers the possibility of amusing confusion.
