Mitchell’s most celebrated work was his discovery of the universality of the period-doubling transition to chaos and the associated Feigenbaum constant, δ = 4.6692016 …. His predictions were confirmed experimentally in Albert Libchaber’s convection experiments in 1979. For their work, the two men shared the 1986 Wolf Prize in Physics.p. 67en-USCopyright © 2019 American Institute of Physics.
