I would like to find a free online course, not too hard. I have minors in math and physics, but have been away for awhile. Maybe something on youtube. If someone knows of a decent course that I could educate myself with I would appreciate any info on it. Thanks in advance, Malcolm.

You should go through both the courses and see which is suitable for you. I think the one by Prof. Harbola is good for beginners. Once you're done with that, go over to Prof. Balakrishnan's lectures.
In case you like to start directly with the rigors, but at a lesser math level, I've got a great book. If you want, I'll tell the name and how to buy it. But first check these courses.
