Why does mathematics deal with the world of perfect spheres, triangles and squares. I understand how this can be applied to architecture and engineering. But this seems counter-intuitive to 'nature' that surrounds us which is objects that are not perfect in shape. The earth for instance isn't a perfect sphere it budges out at the equator. So why is mathematics always prone to using perfect angles and objects to be measured when nature isn't that way at all.(adsbygoogle = window.adsbygoogle || []).push({});
