The Tsallis distribution was introduced in 1988 by Constantino Tsallis as a generalization of the Boltzmann-Gibbs distribution and has been used in many fields of physics.
In high energy physics it has been used by several large experimental collaborations (PHENIX, STAR, ALICE, ATLAS, CMS, …) and describes astonishingly well transverse momentum distributions in proton-proton collisions.
by Jean Cleymans
Image caption: For high energy physics a consistent form of Tsallis statistics for the particle number, energy density and pressure is given by these three equations where T and μ are the temperature and the chemical potential, V is the volume and g is the degeneracy factor. The Tsallis distribution introduces a new parameter q which for transverse momentum spectra is always close to 1.

Alan Turing is famous for cracking the Enigma code during the second World War, but he was a polymath, and worked on many other problems. In 1952, Turing published a paper, The Chemical Basis of Morphogenesis , presenting a mechanism of pattern formation. He developed a theory of how the chemistry in the cell influences factors such as hair colour.
Turing’s model included two chemical processes: reaction, in which chemicals interact to produce different substances; and diffusion, in which local concentrations spread out over time.
