Engineering & Science Crossword Puzzle

Visit the Crossword Express website - RF CafeTake 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.

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. cruciverbalists are often responsible for designing 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.


Note: A standard for crossword puzzles is when all words in a clue are capitalized, the solution is the abbreviation or acronym for that clue; e.g., Alternating Current = AC.

About RF Cafe

Copyright: 1996 - 2024


    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
