Mathematics is learning of rest. Because, when we count a number, if number move around, we can’t count number. We can only count by number stop moving. But, actuality is all of thing move around. We always walking, bird always flying, time is passing, an electron moving around. Our world is composed of motion and movement. Mathematics don’t refer to moving world. Mathematics usually deal with only world of rest. So, theory of mathematics can’t make clear construction of real world completely.
