Mathematical and Logical Issues in the development of Einstein's time

The Special Theory of Relativity, which was developed by Albert Einstein, provided the unique concept that ¿Every reference-body (co-ordinate system) has its own particular time¿ as his own words. This concept is widely accepted, not only among scientists, but also the general public, with a popular interpretation of this theory being that the ticking pace of a clock in a moving system is slower than that of the one in a reference stationary system. However, on thorough consideration, we can find several issues related to the development of Einstein¿s concept of time, which implies that the above-mentioned interpretation cannot hold true. This book presents a detailed explanation of the issues using mathematical knowledge provided in junior high school or the upper grade of elementary school, as well as using formal logic applied sometimes by kindergarten children. Therefore, even the common men will understand the issues in the development of Einstein¿s concept of time if the readers forgo the preconception that Einstein is irrefutably right.
