Chris Dewdney

The physicist Chris Dewdney's work has been integral to the development of the Causal Interpretation. Dr. Dewdney pioneered early numerical computations that stimulated renewed interest in the Causal Interpretation. His work was subsequently reproduced in Bohm and Hiley's book The Undivided Universe.

Dr. Dewdney's work includes papers on understanding of quantum interference, quantum tunnelling, measurement, EPR, nonlocal phenomena, quantum fields, field matter interactions, which way trajectories, and "surreal trajectories". These papers helped allow for the Causal Interpretation to develop to the point it has presently.

Dr. Dewdney is mentioned in Bohm's biography, the book the Quantum Dissidents, and in the book Mind, Matter, and the Implicate Order, among other places. He spent time at Birkbeck but is presently located at the University of Portsmouth where there is a page about him.
