I am a theoretical physicist with specialization in de Broglie Bohm interpretation of the quantum theory. I received my Ph.D. in quantum physics from Portsmouth University, England in 1998, under the supervision of Chris Dewdney and now I work as a teacher for maths and physics. I focus my efforts on creating wolfram demonstrations to visualize the trajectory approach to wave mechanics. I’ve used frequently Mathematica since version 2.2. I would like to invite everybody, who are interested in causal interpretation of quantum mechanics to join the “trajectory project”, which consists only of one member -me.
