One Elementary problem of Classical Math

[Sonnet Nguyen <Sonnet.Nguyen@fuw.edu.pl>]

Dear friends,
Too many discusion about tragedy of one "pseudo-Dr. Sc." of math.
The atmosphere of VNSA requires to be cleaned.   

-------------------------Begin-------------------------------
There is an elementary problem (which is known for at least 2000
years) which is known (for people) as the problem of SQUARE OF CIRCLE.

Problem: SQUARE OF CIRCLE
 
Is it possible (or not) to decompose a circle (|z|<1) into (many) finite
parts, which are able to compose into square?

Any Idea?
----------------------------------------------------------

Comment: Greece Phylosophers have known this problem B.C.
         The problem Square of Circle was (fully) solved in 1991(?). 
         The answer is positive.
enjoys,
SN
