How to begin - Science simulator

First I have to say I have no previous knowldge of OGL whatsoever.
I program in C++ and wxWidgets for a while now. I want to learn OGL so as to make simulator for science software (those ugly benzene structure, Newton laws et al). I need your direction on learning and first tutorial I should begin with (Among those many of course)

Many thanks, and pse welcome a new bee in OGL community!

Try this tutorial for OpenGL 3

Thanks a lot. Let me try it out and see :wink:
