Science & Engineering Crossword Puzzle
March 27, 2016

This week's crossword puzzle has a special message included that has to do with why you might be off work on Monday for a holiday. Oh, and it also happens to be the world's most revered religious time of commemoration, which to the delight of some and to the sorrow of others, is rapidly fading into the shadows of time. The colorful 'no-letter' squares were inspired by the type of candy I am eating as I make the puzzle. As always all the other words are from a hand assembled file of thousands of terms from science, engineering, mathematics, chemistry, astronomy, etc. 7 Across + 15 Across to all!

Reproduction of this puzzle without the express permission of RF Cafe is prohibited.
acr. = acronym, abbr. = abbreviation, pl. = plural, wds. = words

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.
