Holland was educated at Hazelwick Comprehensive School in Crawley, West Sussex and at Imperial College.
[1] In 1993, Holland published his book “The Quantum Theory of Motion’’ in which he presented a comprehensive account of the causal interpretation of quantum mechanics initiated by Louis de Broglie and, in a more complete form, by David Bohm.
Drawing upon numerical trajectory-based methods for solving the Schrödinger equation, and upon methods of hydrodynamics, Holland showed in 2004 how the time evolution of the wavefunction could be derived exactly from the dynamical evolution of a congruence of spacetime trajectories.
This is a considerable conceptual advantage in understanding quantum motion and is potentially a computational benefit too.
Using Riemannian geometry Holland formulated this method in very general terms that include as special cases quantum many-particle systems and spin.
