Mazur, a mathematician at Harvard, also received the science medal. According to The Boston Globe, his love of math blossomed from a childhood quest to “better understand the link between his radio station’s transmitter and the home radio receiver.” For the last 50 years, Mazur has used his problem-solving skills to explore number theory.
