Unlike all of the other engineering and science-themed crossword puzzles I have
ever seen, every word and clue - without exception - in these RF Cafe puzzles has
been personally entered into a very large database of relevant terms. The list has
been built over nearly two decades of creating these crossword puzzles. Let me know
if you would like a custom crossword puzzle built for your company, school, club,
etc. (no charge). These custom-made engineering and science-themed crossword puzzles
are done weekly for the brain-exercising benefit and pleasure of RF Cafe visitors
who are fellow cruciverbalists. The jury is out on whether or not this type of mental
challenge helps keep your gray matter from
atrophying in old age, but it certainly helps maintain your
vocabulary and cognitive skills at all ages. A database of thousands of words has
been built up over the years and contains only clues and terms associated with engineering,
science, physical, astronomy, mathematics, chemistry, etc.
cruciverbalist: [noun] cruci- ("cross") + verbal ("words")
+ -ist ("agent, person") -- A person who constructs or works crosswords.
