To see people doing computer science you need to go to a university and watch professors doing research.

Also you can go to computer science conferences such as ACM conferences.

I once picked up a theoretical math book about category theory. It's a lot of the mathematical basis behind data structures; and where terms like "class" come from.

Unfortunately, when I was in undergrad, my school and other schools didn't understand that most incoming students needed "software engineering" instead of "computer science." Although there is a lot of overlap; misunderstanding the intention and purpose of students made it very hard to learn the skills we were there to learn.

I've seen plenty of co.puter magic though.
