Just would like to pitch in what I can...I have a degree in Physics, a minor in Mathematics and I did a lot of work in Nuclear Science. So if you have any questions along those lines don't hesitate to post.
In physics, I can help in the areas of Newtonian Mechanics, Electricity & Magnetism, Modern Physics, Condensed Matter Physics, Quantum Mechanics, Physics of Electronic Devices (a bit rusty on that one) and a spattering of Astrophysics. In math, I can help with most Calculus, Differential Equations and Matrix Theory. I can also provide introductory informaion in Thermal Engineering and Nuclear Science. Hope I can help someone!
P.S.: Though I doubt anyone would need the help but I have a good beginner's knowledge of the Quantum Criticallity of solids (which involves many topics).
