Firstly, I am new to this forum and this is my first post, so if I've posted to the wrong place or somehow violated a forum rule, I apologize in advance. This is the most polite forum I have ever found, and I stand in awe of all of you ladies and gentlemen. Will one of you--or all of you--please point out the error of my thinking? This has been on my mind for at least a year, and still I cannot find an answer. I've tried to summarize the problem in the attached PDF.
