Boo! Just checking in.

Just heard third party clients are now banned on Twitter. When the one Iโm using stops working, and since I donโt permit ads on my devices, I wonโt be posting here any more. Iโm on Mastodon as @heafnerj@scholar.social and @heafnerj@mstdn.social. Hit me up!

I truly understand the need for stability, but I really Really REALLY wish @overleaf had an OPTION for using an up-to-date TeX Live distribution with all package updates. It would help with package development A LOT. Future option perhaps?

Remember to delete your account from that shady ID.me โserviceโ or whatever it may be. Fortunately I read the TOS and refused to give them anything other than my email address.

So #AAPTWM23 didnโt really end when I left the hotel because Renee Lathrop and I shared an Uber to the airport and we ran into both @ThePhysicsShow and @sterlace and kept the groove going.

Chapter 3 of David Oliverโs The Shaggy Steed of Physics (Springer, 1994), esp pp. 24-26, is breathtakingly enlightening. #ITeachPhysics

Was at @Powells earlier today and saw a lone hardback copy of Arnold Aronsโ blue book, Teaching Introductory Physics. Someone at #AAPTWM23 had better give it a home! #ITeachPhysics

Iโm happy to share that, as of Tuesday, Iโm starting my term as Vice President at American Association of Physics Teachers - AAPT (while continuing in my other roles). Happy to chat with you, anytime! #ITeachPhysics

To follow up, the situation has been resolved. Thank you!

Honestly, Iโm not at all comfortable with all these third party apps and services AAPT is using. Creating new accounts with entities Iโm not familiar with makes me uneasy. Is our data safe? I donโt like this.

I got these SI challenge coins from Peter Mohr at an AAPT meeting in, I think, Atlanta.
ALT These are two challenge coins, each between the size of an American quarter and fifty cent coin. One side has โSIโ at the center, surrounded by seven congruent segments. Each segment is labeled with one of the seven base SI units with both its symbol and the typographic symbol of the fundamental physical quantity from which that unit is derived (for example, the meter has symbol m and is derived from the speed of light c). The coinโs other side has PML at the center, with Physical Measurement Laboratory and National Institute of Standards and and Technology around the perimeter.

Haven't used my backpack since December of 2021 so cleaned it out and restocked it in prep for my first in-person conference in three years.

This post has been getting some hits. Nine years ago I posted my transcripts. I wanted to show students that we're not defined by letters on paper (except by gatekeepers perhaps). #ITeachPhysics #Ungrading

I have my GRE scores right here and will add them to that post very soon.

scholar blocks certain other servers (namely qoto.org and c.im) so fellow physics types please feel free to follow me at mstdn.social. I will echo my physics stuff there. 1/2

When I signed onto scholar.social in April of 2021, I wasn't aware of the fact that some instances are blocked by certain instances for various reasons. scholar.social is heavily moderated, mstdn.social not so much. I like having multiple feeds. 2/2

Instead of textbook problems, the students were challenged to predict the mass of a shiny metal sphere using what they learned in the SHO lab. The images show the progress of the activity.
