Physics & Engineering Crossword Puzzle - w/Friday's Headlines
May 21, 2017

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). This week's puzzle grid is in the shape of a circulator. Enjoy!

acr. = acronym, abbr. = abbreviation, pl. = plural, wds. = words
