RF Cafe Crossword Puzzle w/Weekly Headlines February 5, 2017
For the sake of avid cruciverbalists amongst us, each week I create a new crossword puzzle that has
a theme related to engineering, mathematics, chemistry, physics, and other technical words. You will
never be asked the name of a movie star unless he/she was involved in a technical endeavor(e.g., Hedy Lamarr). Clues in this week's puzzle
with an asterisk (*) are pulled from this past week's (1/30 - 2/5)
"High Tech News" column on the RF Cafe homepage.
Enjoy!

2017 Crosswords Archive
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.
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 typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
