Guilielmus Thomson, Primus Baro Kelvinis, physicus mathematicus et ingeniarius, hodie praeclarrisumus est non solum quia gradus temperaturae absolutae invenit [1] sed etiam quia analysim mathematicam scientarum electromagneticae et thermodynamicae saeculi 19 maxime ingreditur.

Anno 1851 unam formam secundae legis thermodynamicae statuit cum scripsit:

Non est possibile, nisi facultas immaterialis intercedit, phaenomenon mechanicae derivare ex cuiusquam materiae parte quam frigescimus sub frigidissima tempuratura corporium circumspositorum.[2]

Suis cum Iacobo Ioule operis de caloris natura annos 1852-1856 theoriam kineticam caloris magnopere statuit. [3] 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.
