Pixie Puzzles

When running the Scottish Physics Teachers Resource website ( I occasionally published some cryptic crosswords for the members to try. They included a lot of physics and astronomy terms and facts, and not a few in-jokes. Only two people to my knowledge ever completed the puzzles, although there may have been more. One is the very clever and erudite John Lovell, for whom I promised to try to make some more: Pixie Puzzle No. 12 was published in May 2018 in response.

The Cryptic puzzles: No. 1 No. 3 No. 4 No. 5 No. 6 No. 7 No. 8 No. 9 No. 10 No. 11 No. 12

The solutions can be found at Number 2 was a word search, specifically for Sean Duffy.
