Equations that Rule the world

A great video about some of the equations that rule the world whole universe! You may not understand some of them and are surely not able to solve them (at least if you are one of my pupils at IES Santa Rosa). But you can start to get a grasp of it and understand why it is that we invest so much time in learning how to solve equations, how to translate word problems into algebraic language, etc.. Enjoy it!
