Relativistic Complex Analysis

If we follow an ancient Greek philosopher saying "there is no perfect
circle in our world", every physical value must be rational number.
However I thought the light speed only is irrational, and our
(classical) world is composed of Q(c) (i.e. rational number field Q
adding the light speed c). And I found Minkowski metric was very
naturally induced on Q(c). For details, visit;
