# Computer science eponyms

Computer science needs more eponyms, in the vein of Mordenkainen. Collect them all, and impress your friends! I might make a project one day of summarizing these entries.

Explicitly *not included* in this list are: general logic (Peano and Presburger arithmetic, Herbrandization), mathematical entities not primarily associated with computer science (Markov's inequality, Chapman-Kolmogorov equation, Young tableaux), physical theories to which computer science is merely applied (Navier-Stokes equations, Taylor-Couette flow), nor statistical entities not primarily associated with computer science (Ziph's Law, Pareto efficiency). Explicitly *included* are: terms from computer engineering (Mead-Conway rules, Ling adders).

**UPDATE** the threshold for inclusion is now: **De Morgan's Laws**. If you're not at least as computer sciency as **De Morgan's Laws**, you ain't gettin' in. Dank 12:25, 3 October 2011 (CDT)
