## “General” Interest Articles^{†}

Weinstein article: (1996) *Groupoids: unifying internal and external symmetry*.

In this short tour, mathematician Alan Weinstein discusses groupoids in terms of the tiling pattern on a bathroom floor.

Gromov article: (2012) *In a search for a structure, Part 1: On Entropy*.

Category theory is the appropriate language for describing entropy. (Also available on Gromov’s website.)

Baez, Stay: (2009) *Physics, topology, logic, and computation: a rosetta stone*.

The authors use monoidal categories to discuss important phenomena in each of these four fields, such as Feynman diagrams, cobordisms, and the lambda calculus.
