The theory of relativity represents one of the pillars of modern theoretical
physics. As the theory of relativity deals with the properties of space
and time, it represents the framework for any other theory, especially the quantum
mechanics. In the series of articles, we explain the role of the theory of
relativity in theoretical physics. The postulates of classical physics are mentioned
for didactical purposes, and Einstein’s postulates of the special theory of
relativity are introduced. Then, we examine the consequences of the postulates
and we translate them into the geometrical language of Minkowski spacetime.
It is demonstrated how geometry can help us to understand the relativistic
effects (time dilatation) and causal relations between events. Finally, we present
the geometrical explanation of the twin paradox. In the following parts
of the series, we focus on the general theory of relativity and the relationship
between special relativity and quantum mechanics.
