Hi Ivars!

Do you really mean that Pi, i and e are just symbols an that 1/2 and 1/3 are true constants? How can we detect if a constant is ... true? If I say, for example, that the measure of an angle is alpha = Pi, shall we immediately understand that it is not true ? I think that I am missing something.

My old sarcastic reference to the SR was caused by the fact that I read a paper of very famous Soviet mathematician, former president of an important Academy, who said that a consistent mathematical theory of complex numbers is impossible, because they are just symbolical useless contradictory ... approximations. The example he gave was the fact that in the physical reality (SR...?) they only appear as complex conjugate entities. He also added that it was impossible to distinguish between +i and -i.

Well, ... I go and drink a cup of coffee. Then, ... we shall see.
