| | So I've written an article about the above questionfor PBS's website---a sort of tl;dr version of my 2005 survey paperNP-Complete Problems and Physical Reality, butupdated with new material about the simulation of quantum field theories and about AdS/CFT. Go over there, read the article (it's free), then come back here to talk about it if...

| Clojure is a dynamically, strongly typed programming language. It's a dialect of _Lisp_ running on the Java Virtual Machine. Lisp is 6 decades old and has a really weird syntax. That weird syntax is called _Polish prefix notation_. Basically, in every other language you've used math operators like plus or minus are infix. It means they are placed between operands. For example, `1 + 2`. In Clojure, you always put the operator (or any other function for that matter) in front. So simple addition becomes... `+ 1 2`.
