Lorenz's Work in the Chaos Field and Basic Chaos Edward Lorenz was a mathematical meteorologist during the 1960s. In 1961, an experiment with a primitive weather predicting program lead to the discovery of the theory of chaos. Lorenz defined chaos as "a system that has two states that look the same on separate occasions, but can develop into states that are noticeably different.” He started exploring further into the chaos field and performing experiments that lead to his discovery of the Lorenz equations in 1963. In 1961, Lorenz developed a weather model consisting of twelve non- linear equations. This model included barometric pressure, wind velocity, temp
