Andy Bramante left his successful career as a corporate scientist to teach public high school --- and now helms one of the most remarkable classrooms in America. Bramante’s unconventional class at Connecticut’s prestigious yet diverse Greenwich High School has no curriculum, tests, textbooks or lectures, and is equal parts elite research lab, student counseling office and teenage hangout spot. United by a passion to learn, Mr. B.’s band of whiz kids set out every year to conquer the brutally competitive science fair circuit. They have won the top prize at the Google Science Fair, made discoveries that eluded scientists three times their age, and been invited to the Nobel Prize ceremony in Stockholm.
