| Having read the previous paragraphs the student can appreciate that mathematics can be used to represent, or describe, any phenomena, or physical happening, that can occur. If a phenomenon cannot be related to mathematics, then mathematics cannot be utilized to predict that phenomena. After all, the things and phenomena were here all the time and the math was developed by people who started understanding that physical phenomena are related to physical causes. Mathematics has the practical purpose of relating different physical factors to each other. The great mathematician Felix Klein once said "Physics is geometry." By this he meant that because physics is concerned with developing an understanding of all physical things, then, geometry, which is mathematics, can be related to all physical things. In other words, mathematics is universal and can be applied to, and, apparently, be used to help students understand, or solve, any physical problem .
