The Tsallis Distribution via @ALICEexperiment
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.

How leopards get their spots, and other maths problems via @AlanTuringYear
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.

Richard Feynman: Ode to a flower
I have a friend who’s an artist and has sometimes taken a view which I don’t agree with very well. He’ll hold up a flower and say “look how beautiful it is,” and I’ll agree. Then he says “I as an artist can see how beautiful this is but you as a scientist take this all apart and it becomes a dull thing,” and I think that he’s kind of nutty. First of all, the beauty that he sees is available to other people and to me too, I believe…
I can appreciate the beauty of a flower. At the same time, I see much more about the flower than he sees. I could imagine the cells in there, the complicated actions inside, which also have a beauty. I mean it’s not just beauty at this dimension, at one centimeter; there’s also beauty at smaller dimensions, the inner structure, also the processes. The fact that the colors in the flower evolved in order to attract insects to pollinate it is interesting; it means that insects can see the color. It adds a question: does this aesthetic sense also exist in the lower forms? Why is it aesthetic? All kinds of interesting questions which the science knowledge only adds to the excitement, the mystery and the awe of a flower. It only adds. I don’t understand how it subtracts.
