The pasteurization is a process attributed to Louis Pasteur who used it in 1865 to preserve wine thanks to the destruction of its germs. This process, which allows preservation without changing the composition, flavor or nutritional value of the liquid, was actually developed in 1795 by Nicolas Appert who already applied it to milk, wine and beer.
Magnetic Resonance Imaging, MRI, is based on a phenomenon observed in 1938 by a certain Isidor Isaac Rabi on molecular jets. It allows the exploration of the organs of the human body without requiring an operation thanks to the detection of the signals of Nuclear Magnetic Resonance (NMR) emitted by hydrogen atoms in tissue.
