Jean-Pierre Petit  Jean-Pierre Petit (born 5 April 1937, Choisy-le-Roi) is a French scientist. He retired as a senior researcher at National Center for Scientific Research (CNRS). In the early 1980s, Petit authored the science comic book series "The Adventures of Archibald Higgins". He explored ufology, 9/11 conspiracy theories; hypersonic military weapons like Aurora, Ayaks, Avangard. He engaged with French domestic policy issues, especially the yellow vests movement, which he publicly supported. Jean-Pierre Petit obtained his Engineer's degree in 1961 at French aeronautical engineering school ENSAE (Supaero). In the 1960s, he worked in a French rocket engine test facility as a test engineer in the development of the first Submarine-launched Ballistic Missiles. In 1965 he was hired by the "Marseille Institute of Fluid Mechanics" (IMFM). He worked as a research engineer conducting research in magnetohydrodynamics (MHD). Petit defended his doctoral thesis University of Provence in 1972. In 1974, he officially stopped experimental research in MHD and started working at the Marseille Observatory. He was co-director of the "Calculation Center" at the University of Provence from 1977 to 1983, where he developed CAD software in 1978. He retired from CNRS in April 2003. In 2007, he founded a non-profit organization called "UFO-Science." In 1983, he summarized his research about MHD propulsion and aerodynamic flow control in a scientific comic book titled "The Silence Barrier". In 2007 Petit created "UFO-Science", a non-profit organization devoted to scientific study of the UFO phenomenon. He studied electromagnetic plasma propulsion and supersonic flight without shock wave through flow control by MHD force field in a new laboratory running with private funds, called LAMBDA λ ("Laboratory for Applications of MHD in Bitemperature Discharges to Aerodynamics"). He created this concept of "Citizen Research" because he claims the Establishment represented by official scientific public administration, such as the CNRS and the CNES, failed to consider his ideas because of military strategic implications. This laboratory has published results since 2008 in the journal "Acta Physica Polonica", and in associated presentations at international MHD conferences. In topology, Petit worked with Bernard Morin on the torus and sphere eversion. In the 1980s, he taught sculpture at the art school of Aix-en-Provence, where he designed a 5-foot diameter model of Boy's surface that was exhibited in the π room of the Palais de la Découverte for 25 years.
