This custom made Science & Scientists theme crossword puzzle for February
20th is provided compliments of RF Cafe. All RF Cafe crossword puzzles
are custom made by me, Kirt Blattenberger, and have only words and clues related
to RF, microwave, and mm−wave engineering, optics, mathematics, chemistry, physics,
and other technical subjects. As always, this crossword puzzle contains no names
of politicians, mountain ranges, exotic foods or plants, movie stars, or anything
of the sort unless it/he/she is related to this puzzle's technology theme (e.g.,
Reginald Denny or the
Tunguska
event in Siberia). The technically inclined cruciverbalists amongst us will appreciate
the effort. Enjoy!
