How does math/science make the world a better place?

What a very philosophical question. One reason that maths makes the world better is that it is widely regarded that maths is universal. Universal means that our maths here on earth would be the same anywhere else in the universe obviously we will use different symbols but the fundamental ideas will be the same this allows us to contact any intelligent life in the universe. In regards to science the idea is that we look to science and scientists to tell us the answers of the universe. Known as a naturalist view this is a very widely accepted idea that science gives us a greater understanding of the world around us. Science looks at the world in a very structured way using the laws of nature, physical constants and proofs just to name a few. This allows us to view the world differently to have religion views it for example. Whether you are or aren't religious it is hard to argue that science doesn't offer a great alternative view of the world. Everyday when you drive a car or your heart pumps blood we want to understand why this works in such a way. Science can give us these answers and as time goes by we review these theories and we make them better as we know more about the world. Hope this helps but is only a drop in the water on what is a fantastic philosophical debate.
