Even if physics was never the center of my interest, I was always eager to understand “why” and “how” the world works as we know it does.
Over time I understand more and more what is the value of a good teacher. I was in the school, of course, I got my education, but somehow it seems that the teachers that I had were never able to explain in easy words either “why” or “how”.
These days I got the answer that I was looking for, maybe only partially, and it turns out that Einstein‘s equation E=mc2 represents the answer for the “why”- question.
The people from the SBS have made a wonderful documentary called “Einstein’s big idea”. It takes you from the beginning, when Émilie du Châtelet has discovered that the Leibnitz calculations about the kinetic energy were correct and not the Newton ones, that is E=0.5*mv2, or later, when Lavoisier have been determined that nature is a closed system, when he have demonstrated with an experiment that in any transformation, no amount of matter(mass) is ever lost and non is gained. From general theory of relativity we know that mass(matter) and energy is equivalent. The movie goes even further, when Faraday define what we know as electromagnetic induction.
All these contributions to physics and chemistry had led Einstein in 1905 to that equation what we know today as E=mc2.
So here is the movie:

Thank you Einstein for unveiling the world so as we can see it as it really is.
