William Rowan HamiltonIn science, William Rowan Hamilton (1805-1865) was an Irish mathematical physicist whose 1834 two-part publication “On a General Method in Dynamics”, one of the founding papers in the science of dynamics, served as a mathematical basis of logic for German physicist Rudolf Clausius’ mathematical foundations, particularly on the calculation of work done or consumed in a system of particles acted on by forces, to his 1865 textbook Mechanical Theory of Heat. [1] In particular, according to Clausius, was Hamilton’s derivation of what he called the “force-function”, defined as: [2]

W = F(xyz) + const

in which the work W done by forces acting on a system of particles can be expressed as a function F(xyz) of rectangular coordinates. Hamilton was looped into the early thermodynamics network via his correspondence with Scottish mathematical physicist Peter Tait. [3]
