Jean graduated from the French Air Force Academy as an engineer in 1975. After flying school, he joined the French Military Airlift Command where he qualified as a captain and was promoted to Flight Safety Officer. In 1987, in charge of prospects in the French Air Force after a graduate course at the “Ecole Militaire” (Paris), he was also involved in R&D management, advanced studies, innovation policies, patents, and has carried on within NATO “Research and Technology Agency” and the French MOD “Direction de la Recherche et de la Technologie”, to reach ten years of experience in futurology. Captivated by neural networks, at first the artificial ones, and the tricks to make them learn, he then left the Air Force (1998), diverted to cognitive and neuro-sciences and the human brain’s “simplexity” in order to experience and study, for another ten years, the difficulty of implementing logical processing in pupils’ minds. He is working now on a non-logical way of thinking, so called “magic thinking” in recent literature dedicated to gifted children.
