This is the homepage of Dr. Stephen J. Greenfield
I recently took multivariable calculus with Dr. Greenfield as well as taking a freshman level seminar with him in which he taught Maple(the mathematical modelling software). His website if full of amazingly entertaining (and informative of course) lecture notes, as well as a couple of hidden goodies. Definitely a great resource.

Dr. Z is one of Rutgers University's star players. A humble man with countless accomplishments. Every link on his website is extremely interesting and a great way to kill a few hours. I highly recommend his OPINIONS page. Every single opinion is insightful and makes math seem more human and friendly, just like Dr. Z!
Dr. Z's crystal clear calculus notes are just as helpful as Dr. Greenfield's assorted lecture notes.
This is the home page of Blase Ur.
I took Intro to Computers for Engineers with Blase.This class provides a very clear intro to MATLAB a mathematical modelling software. He is very helpful, with a large wealth of knowledge from computer science to very obscure music. He has been very kind and has posted his own MATLAB lecture notes on line. They are well thought out, and simple enough to follow. I highly recommend them if you seek MATLAB help
