This was impressive! I thought the fill was solid, actually, and my solving experience was smooth and fun. Loved that you went straight there with 12A.
One question and one error:
Q: Loved the straight definition of 25A; can you help me parse the “and” version? (Maybe I am misunderstanding the “each” part?)
E: A POINT is 0-dimensional (one needs 0 coordinates to locate one’s position within it) while a line (or ray, or segment) is 1-dimensional.
Thank you! I guess the wording of "each" isn't totally correct, so that's actually two errors I suppose lol -- I'm pretty sure you're understanding it correctly
