RF Cafe Engineering & Science Crossword Puzzle
December 30, 2018

Each week, for the sake of all avid cruciverbalists amongst us, I create a new technology-themed crossword puzzle using only words from my custom-created lexicon related to engineering, science, mathematics, chemistry, physics, astronomy, etc. 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 who or that is directly related to this puzzle's theme, such as Hedy Lamarr 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
