You've heard of shareware...

So why not try courseware? Some of the personal messages I recieve on forums/Youtube are vague, random scientific questions. An exchange between us without the other person willingly doing their own research always proves to be insignificant. I promise there are answers to your questions and a great place to find them is right in front of you.

Here's my favorite source for open courseware, MIT.
