<p>Hey G.P. you seem to have different references to go to that are very interesting. I went to the one from MIT that you mentioned which is very cool. I was curious if you are still in school, if not what type of work do you do? Also for this thread… I found a website that helps with refreshing math and science courses. Its not from a school but I found it very helpful [Khan</a> Academy](<a href=“http://www.khanacademy.org/]Khan”>http://www.khanacademy.org/) I wonder if anybody else has heard of it.</p>
