Since Newton represents the mechanics and gravitational side of physics, Archimedes represents fluid dynamics (maybe

), Galileo represents astronomy, and Curie represents Nuclear Physics (to some degree), there needs to be a person from Electronics and Magnetism recognized. The robot building is half mechanics and half E&M so E&M should also be recognized.
Maybe Gauss, Ampere, or Faraday
of course, its time that a field gets named after either an American or an Asian.
