The idiomatic expression "Squaring the Circle", a term used as a metaphor for trying to do the impossible, is a mathematical problem proposed by ancient geometers. /G\
It is the challenge of constructing a square with the same area as a given circle by using only a finite number of steps with the aid of the compasses and the straightedge or a square.
In 1882, the task was proven impossible, as a consequence of the Lindemann-Weierstrass theorem which proves that pi is a transcendental number.
As result, the expression "Squaring the Circle" is now used as a metaphor for trying to do the impossible.
According to ancient belief, man arose from the coming together of a soul and a body. The Circle (formed with the aid of the Compasses) is a symbol of the sun or that which is Above (the heavens, the unseen, the spirit, the soul); while the Square represents that which is Below (the body, the building block, the material). As Above, So Below.
Now that we have this picture, we can arrive at the conclusion that man himself, therefore, is the key to this seemingly impossible problem. The Square and Compasses is the symbol of the unified man.
Our beloved Masonic emblem shows that great impossible things can be made possible by those who remain true to the ideals of the Gentle Craft. -
The S&C is a visual reminder that our potential is limited only by the bounds of our creativity and imagination. Impossible is merely a state of mind.
