@danny.hellmo.space Congratulations! However, it looks like the word physics is misspelled in that picture (is that the cover?).

I checked with my son, who just did that AP test, and he had that question!

I’m not sure I know what is meant by level curves but PhET has a very nice Charges and Fields sim that does equipotentials.

Is there going to be a That Curling Show anytime soon, Devin?
