Physics & Engineering Crossword Puzzle w/Headlines
March 13, 2016

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 directly from this week's "High Tech News" column on the RF Cafe homepage. Enjoy!
