    The MaxEnt 2010 conference was held in Chamonix, France. One of the most breath-taking experiences was the excursion to the top of Aiguille du Midi in the French Alps. After a ride on the highest vertical ascent cable car in the world, you are presented with a panoramic view – Mont Blanc on one side and Chamonix far below on the other.
  • Symmetries and transformations are explored in the framework of entropic quantum dynamics. In particular, we apply this to the extended Galilean transformation, which admits features of both special and general relativity. An effective gravitational potential arises naturally through an equivalence of information.

My name is Dave Johnson. This website is a repository for my research, projects, demos, and random thoughts. Feel free to browse around.

Computational Projects
I've written programs in numerous languages over the years. Most of my private projects were developed for my own needs, but I have developed software some that may be useful to others.

My field of research in grad school was information physics. In particular, I worked on the development of entropic quantum dynamics, a formulation of quantum mechanics in terms of information.
