Dating back to the seventeenth century—when King Louis XIV established the first institute for scientific research named ‘Acádémie des Sciences’—technology and science in France have come a long way. The development of groundbreaking inventions like radioactivity, refrigerators, photography and parachutes, amongst others, have made French scientists famous all over the world. France lays claim to being a major exporter of nuclear technology, as well as the inventor of safe radioactive waste disposal methods. Many utilitarian innovations have been made by French scientists; these famous scientists have won the prestigious ‘Nobel Prize’ for their invaluable contribution to the advancement of human society. Science would not have been the same had it not been for scientists like Henri Becquerel, who discovered ‘Radioactivity’; Antoine Lavoisier, who proposed the ‘Conservation of Mass’ theory and Blaise Pascal, who came up with the ‘Probability Theory’. French scientists have always been leading contributors to the world’s scientific advancements, be it in the field of chemistry, or molecular biology or radiology or the physical sciences.
