A Pi Symbol ( )
Enclosed In A Circle
Pi is a fundamental ratio in mathematics and geometry, and it is
relevant to all engineering design. You can see the symbol in all
our company logos.
These are formulae we are all familiar with and use everyday,
sometimes without realising it. However the actual value and meaning
of pi has been of major interest to mathematicians for centuries.
This is because the number (3.1415926535897932384626433832795...)
appears to have no ending and also no pattern to its sequence of
digits.
Pi as such has of course always existed, but early references to it
go back over 4000 years with one of the earliest estimates of its
value coming from and Egyptian scroll (the Rhind Scroll 1650 BC) For
1000 years pi remained a rough aid in calculating plots of land and
by 200 BC after Archimedes examined Pi, a more exact figure was
arrived at.
In 1748 a Swiss mathematician, Euler, gave the ratio the name "Pi"
and the Greek Symbol
In Dutch mathematician, Ludolph Van Ceulen, later calculated pi to
35 decimal places, in 1873 an English mathematician, William Shanks
spent 20 years calculating by hand to get a value of pi to 707
decimal places, however in 1945 his figure was discovered t o be
wrong due to an error in the 528th place.
Now with computers further studies have gone to 6 billion places and
still falied to come to an end or establish a pattern.
