Here's a heartwarming mini-doc to get you in a thankful mood before the holiday insanity sets in. Kelvin Doe, a 15-year-old engineering prodigy from Sierra Leone who builds functional generators and radios out of discarded materials in his spare time, received an invitation to do a three-week residency at MIT this year. Follow the music-loving, casava leaf-craving teenage genius as he leaves his home country for the first time, visits New York, shares a lab with pasty, bespectacled MIT students and even meets the president of Harvard. When we were 15, we just wanted to meet Lizzie Barnes behind the bleachers.
