For 10 points, name the Scottish physicist whose equations unified electricity and magnetism.
His 1861 paper On Physical Lines of Force set forth a "spinning cell" model of electromagnetic induction, and that same year he accidentally showed the world's first color photograph at a Royal Institution lecture. Other accomplishments include producing a standard for electrical resistance and deducing the particulate nature of Saturn's rings. His demon tried to violate the second law of thermodynamics, his distribution is central to statistical mechanics, and his relations equate the second derivatives of thermodynamic potentials.
