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). Enjoy!
