This man generalized Cayley's formula into a theorem giving the number of spanning trees in a graph; that is his matrix tree theorem.
This man generalized Cayley's formula into a theorem giving the number of spanning trees in a graph; that is his matrix tree theorem. A set of laws named for him includes the statement that a gas at a high temperature and low pressure will emit an emission-line spectrum, and with Piola, he names a stress tensor. With a colleague, this man discovered (*) cesium and rubidium; that colleague was Robert Bunsen. One of this man's rules states that the potential differences across all elements around any closed circuit loop must be zero. For 10 points, identify this German physicist who coined the term "black body radiation" and names two circuit rules.
