 ## The CAP theorem
 
-The CAP theorem was initially a conjecture made by computer scientist Eric Brewer. It's a popular and fairly useful way to think about tradeoffs in the guarantees that a system design makes. It even has a [formal proof](https://www.google.com/search?q=Brewer's+conjecture+and+the+feasibility+of+consistent%2C+available%2C+partition-tolerant+web+services) by [Gilbert](http://www.comp.nus.edu.sg/~gilbert/biblio.html) and [Lynch](http://en.wikipedia.org/wiki/Nancy_Lynch) and no, [Nathan Marz](http://nathanmarz.com/) didn't debunk it, in spite of what [a particular discussion site](http://news.ycombinator.com/) thinks.
