This technically themed crossword puzzle for November 14th contains only clues and words
are directly to RF, microwave, and mm-wave engineering, optics, mathematics, chemistry,
physics, and other science 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!
