I've always asked myself why do we see the world we're living in the way we see it. Very intriguing question that's why I made some researche about light in general and found out a catching topic which is that light behaves as a wave. I mean it's really hard to imagine how can light travel following a very weird pattern which we dot not see when we perceive things right? And that's how i chose to talk about it. Sometimes obvious topics should be covered to have a stong and reliable knowledge about them rather than have assumptions.
