For the sake of avid cruciverbalists amongst us, each week I create a new crossword puzzle that has a theme related
to engineering, mathematics, chemistry, physics, and other technical words. You will never be asked the name of a
movie star unless he/she was involved in a technical endeavor
(e.g., Hedy Lamarr). Enjoy!
Reproduction of this puzzle without the express permission of RF Cafe is prohibited. acr. =
acronym, abbr. = abbreviation, pl. = plural, wds. = words
Note: A standard for crossword puzzles is when all words in a clue are capitalized, the solution is the abbreviation
or acronym for that clue; e.g., Alternating Current = AC.
