We are interested in physics and chemistry , the brain which is not stuck in the swamp of uncertainty created by theoretical physics today. We are interested in the real financial structures , and scientists - physicists, chemists, technicians and technologists broad-minded , and not in the narrow , dogmatic one specialized research topics.
