Physics Theme Crossword Puzzle
May 30, 2021

For twenty years now, I have been creating weekly crossword puzzles for the education and enjoyment of the technically minded visitor like you. This Physics Theme Crossword Puzzle for May 30th has many words and clues related to RF, microwave, and mm-wave engineering, optics, mathematics, chemistry, physics, and other technical subjects. As always, this crossword 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!
