They say you don't regret what you tried, you only regret what you wanted to but never tried. From his perspective, he obviously seems attracted to you - otherwise he wouldn't have tried to get your attention on him by asking you to help him with a physics problem. There's more than one way to skin a cat (or approach a girl), and rather than try to get you to be impressed with him, he instead tried to show how impressed he was with you. That takes daring. People like to say "Oh, just ask her, what's the worst that can happen?" but for lots of men fear of rejection can be a real showstopper. You probably understood how nervous he must have felt, gathering up his courage for a good 10-15 minutes before putting his dignity on the line and offering you his contact information.
Now, what we didn't get out of this story was your reaction. Did you smile at him? (Guys notice when a girl smiles at them. Really.) Did you give him the awkward deer-in-the-headlights look? (Also a natural reaction.) Did you thank him for the information, or was it a blank stare that followed? You can be sure that he'll be mulling over all your little facial expressions, actions, or inactions for some time, every bit as much as you are thinking about him and over his actions. Your post has the tone of "well, the attraction's there, but I'm not too sure ..." and I'll flag the telltale sign: you think he's nice and respectable and all that, but you aren't too thrilled of the idea just yet because you've read his body language. Attraction builds on positive feedback. If you smile at him, nod at his statements, keep your eyes "sticky" on his, your body language is conveying the mood of "I like you and am interested in what you have to say." If you can't meet his eyes or show little reaction, then your body language conveys the "you're boring me, can we stop?" mood. In the same way, you've noticed his body language - he obviously feels attracted to you, but you picked up that he's nervous, jittery, may not even have asked out this strange, mystical creature called "girl" before, and is afraid of rejection.
What I suggest is getting to know him a bit better before making your decision. There's no need to rush into things. Don't use Facebook or e-mail - voices convey your intent much better than text does. Call him up and ask him out for coffee or to study together, but when you do, you need to sound interested and receptive. Rehearse your tone and voice beforehand if necessary. He'll be nervous, and so will you, so it is important that you school yourself to be relaxed but confident. Confidence and interest in you will breed confidence and interest in him; if your body language, expression, and tone of voice tell him that he can relax, be himself, and open up, he will (and you want this). Conversely, if your body language, expression, and tone of voice tell him that you're cool to the idea, evaluating him, and scrutinizing his actions, he may be on his best behavior but you'll find it stiff, wooden, and nervous.
If you feel that it won't work, let him know. Guys take rejection badly, but most will settle for being "just friends". What you should not do is remain indecisive after a long time; if you feel the answer is "yes", say yes. If you feel the answer is "no," or even "maybe", then say no. Firmness stops a lot of potential problems down the line.
Just my thoughts. Hope this helps.
