I am impatient, to put it mildly.

You have given us a blizzard of questions over the past few weeks, many of which seem like paraphrases of one another. There is so much clutter that I cannot remember what you said about your background, if any, in basic math and physics. Many of your questions are about things that are at the Ph.D. level of study. My personal experience is that mathematics and physics courses are brutally unforgiving of missed prerequisites.
