I want to share those videos because they explain in a very simple and clear way a Knowledge that is so important for me personally and generally for everybody else that like me want to keep clear in his mind that "The universe is a book written in mathematical language".
I like to keep this kind of Knowledge near to me, like a personal archive in order to consult/show it in an easy and fast way and steemit is a perfect tool to do this, if you love these videos like i do, please upvote and resteem.
