RF Cafe Crossword Puzzle w/Weekly Headlines
January 29, 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). Clues in this week's puzzle with an asterisk (*) are pulled from this past week's (1/23 - 1/27) "High Tech News" column on the RF Cafe homepage (see the Headline Archives page if necessary). Enjoy!

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