Probably no symbol in mathematics has evoked as much mystery, romanticism, misconception and human interest as the number Pi ( ) This was proved by Lambert in 1761. In 1882, Lindemann proved that Pi was more than irrational --- it was also transcendental --- that is, it is not the solution of any polynomial equation...

German mathematician who proved \pi (pi ) to be an irrational number and introduced hyperbolic functions. He devised techniques for measuring light intensity accurately. He also wrote influential books on geometry, the theory of cartography, and perspective in art. Additional biographies: MacTutor (St. Branch of Science...

For many centuries prior to the actual proof, mathematicians had thought that pi was an irrational number. The first attempt at a proof was by Johaan Heinrich Lambert in 1761. Through a complex method he proved that if x is rational, tan(x) must be irrational.

Since both (10^(N+1)) and (M*10+A) for A between -5 and 5 are integers, the (N+1)-digit approximation of pi is also rational. One can also see that adding one digit to the decimal representation of a rational number, without loss of generality, does not make an irrational number.

In 1767 a mathematician named Johann Heinrich Lambert proved that pi was an irrational number. Irrational numbers are numbers that do not terminate or repeat when written out as a decimal. Does it ever turn into a pattern of zeros and ones?
