RF Cafe Engineering Crossword Puzzle w/Weekly Headlines
October 15, 2017

For the sake of avid cruciverbalists amongst us, each week I create a new technology-themed crossword puzzle using only words related to engineering, science, mathematics, chemistry, physics, astronomy, etc. At least 10 clues in this puzzle with an asterisk (*) are pulled from this past week's (10/9 - 10/13) "Tech Industry Headlines" column on the RF Cafe homepage (see the Headline Archives page for help). Enjoy!

cruciverbalist: [noun]  cruci- ("cross") +‎ verbal ("words") +‎ -ist ("agent, person") -- A person who constructs crosswords.
