This custom RF Cafe engineering & science themed crossword puzzle for February
11th contains only clues and terms associated with engineering, science, physical,
astronomy, mathematics, chemistry, etc., which I have built up over more than two
decades. Being the 11th day, words containing the letter "K" are marked with an
asterisk (*). 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!
