First input and introduction

This blog is a continuation of my first website entitled "A physical place" and created in 1996. At that time the site was dedicated to light as a physical phenomenon. It was a small project for my spare time and due to other occupations did not last, but achieved the objective of discovering the Internet, learn its operation and intuit their potential. At that time Internet was not popular at all. The purpose of this blog is to continue writing on this subject and also about the medium that makes it possible, that is the void. The light uses the vacuum as a medium of propagation. Therefore we need to know the structure of that medium. The aim is also to discuss news, books and articles related to this subject.
