Everyday and Scientific Language

Unlike everyday language, mathematical, scientific and, above all, computer language uses terms that, by convention, have one and only one meaning.

In mathematics, “straight line” refers to something that does not even exist in reality. In everyday language, however, it can mean an infinite variety of things. “The straight path” may simply mean a road without bends, but it can also refer to what is good or right, which in turn can mean an infinite variety of things.
