It is said "Nothing is impossibe"..Today i was looking into it..I found two instances when the greatest minds in history spend centuries to perform something impossible without realizing.
First it was "Squaring the circle" in ancient Greece,when the greek mathematecians tried for many generations to find a circle and square of equal area which can be fit inside each other.
Then there were the Arab Alchemists who for generations tried to transform different metals into Gold by chemical reactions.
Today we know that both tasks were inpossible and against laws of nature.
Although both the Greeks and Arabs while trying to do the impossible discovered treasure troves of Mathematical and Chemistry knowledge.
But it proves the the term "nothing is impossible" is a generalized terminology.
There are impossible things.
