This video follows the previous one by two days. My shoulder is almost normal, if stiff. That is impossible, from a conventional point of view. The video explains it from the point of view of a physicist, using Richard Feynman's history of states. My hope is that you can use the method also. The video explains how to do it. The video also explains situations when you cannot do it.
Interesting books in science. How to find cheap but, meaningful, enjoyable, even important books. Sorry, I meant to mention Martin Gardner, a great author of easy to read (for anybody interested in learning odd, interesting, even funny stuff about math). I called him Marvin Gardner.

Finally we found the law of nature which prevents time travel paradoxes, and thereby permits time travel. It simply turns out to be the same law that makes sure light travels in straight lines, and which underpins the most straightforward version of quantum theory, developed half a century ago by Richard Feynman.
