I am a physicist from origin, so I haven't had a lot of specialized classes. I always used imperative languages. In physics c++ and c are leading. Two years ago I found Haskell. It was difficult to learn, until I realized in Haskell you are just doing mathematics. In functional languages a function is a mathematical function. You can actually reason about code and even prove your code. This is extremely cool (from my point of view). I purchased some books on lambda calculus, logic, category theory and did the SICP thing. Now functional programming feels more natural to me. I used it as day to day tool.
