RF Cafe Engineering Crossword Puzzle w/Weekly Headlines
July 29, 2018

For the sake of all the avid cruciverbalists amongst us, each week I create a new technology-themed crossword puzzle using only words from my custom-created list related to engineering, science, mathematics, chemistry, physics, astronomy, etc. At least 10 clues with an asterisk (*) in this technology-themed crossword puzzle are pulled from the past week's (7/23 - 7/27) "Tech Industry Headlines" column on the RF Cafe homepage. You will never find among the words names of politicians, mountain ranges, exotic foods or plants, movie stars, or anything of the sort. You might, however, see someone or something in the exclusion list directly related to this puzzle's theme, such as Hedy Lamar or the Bikini Atoll, respectively. Enjoy!

cruciverbalist: [noun]  cruci- ("cross") +‎ verbal ("words") +‎ -ist ("agent, person") -- A person who constructs crosswords.

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