The signs, + , and,  - , are used throughout mathematics and physics in a number of ways,and with several meanings which are often not carefully checked. The plus or positive sign has its initial use in addition in the sense of increasing a pile, of no particular dimensions, by a certain amount described by [...]

In working with numbers one often works with fractional exponents, “roots.”  This works well when one is working with “absolute values, ” unsigned numbers; however, it runs into complications as soon as one starts to operate with “signed” numbers.  The problem probably arises from the inherent fact that absolute number values do not have [...]

Why Einstein was right, when he was, in his “Relativity” theorizing, was often because hidden facets of mathematics and of the definitions used in physics allowed the ideas to be usable, even if his reasoning were fallacious. In other words, often, he was lucky.

Einstein’s Special Relativity, which title for it, I am told, he disliked, [...]
