Today, the world is at a level very high of his history. In fact, today, we have the better technology that there was in the past. this evolution is the frut of some genuises who searched to know, to understand and to ask themselves how to make the life more easy for the men. We have some genuises in math and in physics, such as Isaac Newton; Albert Einstein; Gauss; René Descartes and so on, who marked the history by their discoveries. It's why, we decided to create this blog to congratulate those persons who permit the evolution or have to say the REVOLUTION.
