This guy revisits the ancient problem of squaring the circle and shows that it is possible to square the circle _exactly_ and not just approximately.
In the late 19th century pi was shown not to be an _algebraic_ number. He does not challenge that proof. What he has done is invalidate the assumption that the aforementioned proof demonstrates the impossibility of squaring the circle. His does this by showing that pi is a _composite_ and a _constructible_ number. Unlike the proof of Fermat's last theorem, this is a proof that can be followed without the need to know tons of "higher" math. Harry See: http://members.ispwest.com/r-logan/math.html quotes: "Many mathematicians believe that, because the number pi is transcendental and not algebraic, and cannot be expressed in any form other than that of an unending decimal or as the limit of an infinite sequence, it cannot be constructed as a line segment by any method whatsoever. The fact that a structure could exist, providing insight into this matter, is nowhere to be acknowledged." "We are taught in high school geometry class that if the altitude be drawn to the hypotenuse of a right triangle, each leg is the mean proportional between the whole hypotenuse and the adjacent segment. This then is the essence of what I call the pi/phi structure... "
