Explanation:

It is a book written by Galileo Galilei comparing the Nicolaus Copernicus, published in 1632 aa his dialogue if the two chief world systems. As in the Copernican system of the universe the earth and the other planets orbit around the sun and while in the Ptolemaic system all orbited around the earth. Simplicio which is a dedicated follower of Ptolemy and Aristotle then presented his traditional simple views. Being a geocentric philosopher he opposed the heliocentric which proposed the sun in the center.

May consider a group  g=({0,1},+)g=({0,1},+)where  ++  will work as the xor operator like we work in boolean algebra. note here, that ‘00’ and ‘11’ are not the usual 0 and 1 that we work with everyday. the elements are  called  ‘00’ and ‘11’ and  may not mean  zero (nothing) and one (single). ‘00’ is the identity for the given binary operator +, meaning that any element operated with ‘00’ gets us that element itself.  for a set  ss  in  g′g′  having more elements than just  {0,1}{0,1}  the values for  a+b∈sa+b∈s, such that  a∈s,b∈sa∈s,b∈s, have to be first defined, only then can you determine the value of  1+11+1. the answer could possibly have been  22  if oanswer is25,000
