How old are you? Where are you now? To answer these question is undoubtedly not difficult. But which answers would we get addressing the same questions to the entire Humanity? At what stage do we find humanity? How long will we be able to live on our planet? Can we measure the speed by which our progress goes on? Centuries and millennium to proceed from the simple wheel to the car and few decades to arrive to robots and mobile phones! How so? Why? An "apprentice philosopher" tries to answer with the aid of Mathematics - History - Philosophy - Science-fiction. A theory which can be resumed, challenged, updated, computed again by everyone of you.
