Click both images, it will make them clearer and easier to read. I wrote my master's thesis in part about the subject. If my final paper carries a couple typos I wish I had written it currently, rather than when I had no computer, (lost it due to fire) and more confidence in my words. But the information is such I do not feel it missing in areas of facts. The images are public domain images, and my words are not copyrighted other than to say these are my own words.
