Math is great for dealing with certainties…
In mathematics there is a unifying language that links past discoveries and current theories. We can take a complete block of previous scholarship, plug it into a block of new scholarship, and they will fit perfectly and exactly with one another.
The beauty of mathematics as a system of knowledge is that it allows us to deal with complex problems by building on past knowledge. Once someone formalizes their findings in a proven mathematical model, the whole scientific community can seamlessly integrate it into their research and reach a better understanding of the world we live in.
For example, once Pythagoras proved that a2 + b2 = c2, other mathematicians could use that formula whenever they encountered a right triangle, without having to prove it again each time.
