As an example of my activity in this field, I show here the
abstract of a lecture given at NORDPLUS student workshop
in Oslo, October 1994


Multiple Measurements and Many Worlds

Ladislav Kocbach
Department of Physics
Allegaten 55, N-5007 Bergen, Norway


I was asked to prepare a lecture which would discuss fundamental problems of Quantum Mechanics, and combine it with my work on the visualization of physical processes using computer and video.

I have chosen to present the so called Zeno Paradox of Quantum Mechanics ( ref. 1. and ref.2.), and confront it with the Many world interpretation of Quantum Mechanics ( ref. 3.).

Further, these problems can be illustrated through our visualization of Fermi Golden Rule, running on personal computers or workstations. The programs are available in various forms (ref. 4.).

In the lecture I have given a short introduction to the physics of the Itano et al. paper and also discussed some topics from Time Dependent Quantum Mechanics. The problems of repeated measurement and the complexity explosion have also been discussed. In the second half of the lecture I have shown a videorecording of computer-based lecture, prepared as a combination of prepared 'slides' and runs with our Golden Rule Simulator.

The main point of the Golden Rule Simulator program is that many of the aspects of Quantum Mechanics, which are discussed with difficulties, can be visualized by simple animations.

The "Many World Interpretation" is a special name, given to a much less mystical formal theory, published by H. Everett III as Relative state formulation of quantum mechanics. This can be found in (ref. 3.) or in a much broader perspective in ( ref.5.)
