This week's crossword puzzle, as is the case with all RF Cafe crossword
puzzles, has only words and clues related to science and engineering. Each week
for two decades I have created a new technology-themed crossword puzzle using
only words (1,000s of them) 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, find
someone or something in the otherwise excluded list directly related to this
puzzle's technology theme, such as Hedy Lamarr or the Bikini Atoll, respectively. Avid cruciverbalists amongst us: the gauntlet has been thrown down.
I will be glad to create a special edition crossword for your newspaper, newsletter,
etc.
