How can I get to know this guy who is a loner?

[Sam]

This guy is a freshman in college and he is normally by himself, he doesn't smile often and when others laugh loudly he just barely cracks a sly smile. He doesn't say much, but what he does say is extremely well thought out, he sounds like he is a very educated and wise man. However any social interaction or attempts to prod into his world is met with an elusive sly escape. (socially, he spins the conversation) I have never witnessed him being rude, but he is always polite, humble, and clean. I know he is super smart, for I have seen some of his work he has been doing when I attempt to interact with him.

How can I get to know a guy like this? Is it even worth the effort?
He usually wears sweaters, polos, or sweater vests.
