BTW, I have a more or less academic presence at @heafnerj@scholar.social but that instance is heavily moderated so you may not be able to find me there. Feel free to talk physics, mathematics, physics teaching, and such with me here. My geekiness is independent of my location. #ITeachPhysics #ITeachAstronomy #Physics #Relativity #CommunityCollege #AAPT #NCSAAPT
