Mj's math challenge

Very true, but what good would this one specific type of math ever affect my life? It probably won't, therefourth I don't care.

It affects every aspect of your life. The car your drive. The clothes you wear. Even the coke you drink. That bottle's volume, surface area, thickness and more were meticulously calculated to maximize utility and minimize cost. Notice that some plastic bottles are getting thinner? That's calculus.
