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 (11/20 - 11/24) "Tech Industry Headlines" column on the RF Cafe homepage (see the Headline Archives page for help). Enjoy!
