Non est possibile, nisi facultas immaterialis intercedit, phaenomenon mechanicae derivare e cuiusquam materiae parte quam frigescimus sub frigidissima tempuratura corporum circumpositorum.[3]
Suis cum Iacobo Ioule operis de caloris natura annos 1852-1856 theoriam cineticam caloris magnopere statuit.[4] Annos 1855-1856 Thomson quoque cum Petro Guthrie Tait collaboravit et scripsit suorum magnum "Detractatus de Philosophia Naturali" qui novam disciplinam physicae unificabat sub sententia energiae.[5]
