RF Cafe Engineering & Science Crossword Puzzle
November 5th, 2023
|
|
As with my hundreds of previous engineering and science-themed crossword puzzles,
this one for November 5th uses only clues and terms associated with engineering,
science, physical, astronomy, mathematics, chemistry, etc., which I have built up
over more than two decades. Many new words and company names have been added that
had not even been added to the world's technical lexicon when I started in the year
2002.
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. You might, however, encounter the name of a movie
star like Hedy Lamarr or a geographical location like
Tunguska, Russia, for reasons which, if you don't already know,
might surprise you. The technically inclined cruciverbalists
amongst us will appreciate the effort. A full list of all RF Cafe crosswords is
at the page bottom. Enjoy!
