Task: Text Categorization
Input (English): This man introduced equations characterizing the stability of governors in an early paper on control theory. He showed that only particulate composition can confer stability to Saturn's rings, and he also names a gap in the outer C-ring of Saturn. Experimentally verifiable thermodynamic quantities are used to relate hard-to-measure thermodynamic functions according to a set of relations named for this man. He introduced the displacement current term in another equation, which, along with the Faraday's law and the two Gauss laws were discussed in this man's paper "On the Physical Lines of Force." For 10 points, identify this thinker who grouped a set of four equations from electrodynamics.
Output (English): Science
