WebWhat is reaction-diffusion? Reaction-diffusion is a mathematical model describing how two chemicals might react to each other as they diffuse through a medium together. It was proposed by Alan Turing in 1952 as a possible explanation for how the interesting patterns of stripes and spots that are seen on the skin/fur of animals like giraffes and leopards form. WebReaction-diffusion equations describe the behaviour of a large range of chemical systems where diffusion of material competes with the production of that material by some form of chemical reaction. Many other kinds of systems are described by the same type of relation. Thus systems where heat (or fluid) is produced and diffuses away from the heat (or fluid) … list properties of matter
