I have desire to learn shade writing, how do i start?

Bosh

I am really curious about shade writing. I would like to learn this for production level, either for movie or games.So far, i have been modeling, hard surface and characters. I really want to do also, texturing and also creating shaders/materials. 

But, i am not sure how to even start. I never code in my life,i have no idea what engine should i use, what programming language to learn, and mostly, what theory or physics or whatever math it is involved in this. 

Give me some advice, suggestions, books etc, to start.

There are many resources once you know what to search


I liked the rendering tutorials of this one:

But it might be better to start off with 2d stuff:
