2010 Engineering & Science Crossword Puzzles
 Take a well-deserved break and try your hand at some of these goodies.
Every word in the RF Cafe crossword puzzles is specifically related to engineering,
mathematics, and science. There are no generic backfill words like many other puzzles
give you, so you'll never see a clue asking for the name of a movie star or a mountain
on the Russia-China border.
All of these crossword puzzles were created using the fabulous
Crossword Express (now called "Magnum Opus") software.

Cruciverbalist:
A cruciverbalist is a person who is skilled at creating or solving crossword
puzzles. The term is a combination of "cruci-" from "crucifix," meaning cross, and
"verbalist" from "verbal," indicating a person who deals with words.

crossword puzzles, and they possess a deep knowledge of wordplay, vocabulary, and
the techniques used in constructing and solving crosswords. They aim to make puzzles
that are both challenging and enjoyable for crossword enthusiasts.
