TITLE: What is lambda calculus related to?
QUESTION [15 upvotes]: So I'm not much of a math guy but I've really enjoyed programming in Lisp and have become interested in the ideas of lambda calculus which it is based.
I was wondering if anyone had a suggestion where I should go from here if I'm interested in learning about similar fields. If would be nice if I could relate it back to programming, but not necessarily a prerequisite.
Thanks.

REPLY [3 votes]: I suggest learning Coq.  It's pretty much the most powerful type system with a complete implementation right now.
