        GEOMETRY, CHARACTER AND THE NUMBER OF THE DIMENSIONS OF THE

Absztrakt:
No phenomenon of natural sciences seems  to be better grounded in our 
everyday 
experience  than  the fact that the world of  macroscopic physical reality 
has 
three dimensions we call spatial and one dimension of a different character 
we 
call time.  Although a tremendous amount of effort has been put so far 
towards 
achieving a plausible quantitative elucidation of and deep qualitative 
insight 
into the origin of these two puzzling numbers, the subject still  remains  one
of the  toughest  and most challenging problems faced by contemporary  physics
(and by other related fields of human inquiry as well). 

The aim of the  talk  is to address this issue employing the simplest possible
geometrical  model  based on the concept of the projective plane. I will start
with  a very illustrative  represenation of the projective plane. Next, I will
introduce  the  geometrical definitions of both the time and space dimensions.
Based  on  the  latter,  I  will  try  to demostrate why our Universe has 
four 
dimensions,  why  three  of  them are of a different nature than the remaining
one,  and  why our perception of them is different from what physics tells us.
