After half a dozen newspaper crosswords over the holiday I realized that I don't really care to know the names of famous opera singers or athletes. From a brief Google search, I didn't have much luck finding a challenging physics crossword, so I decided to make one myself (hopefully I'm not the first). A link to the crossword is below, but I'm not sure how long it will stay active. If it goes inactive and you are interested in the crossword, let me know and I will reupload it.
A LinkEDIT:
Some corrections:
1. "Quark of inflation" should be "Quirk of inflation".
2. In the clue containing "volumeaction", everything after volume should be ignored.
Every day I am thankful that I was introduced to psychedelic drugs.
