William Jones and his Circle: The Man who invented Pi. In 1706 a little-known mathematics teacher named William Jones first used a symbol to represent the platonic concept of pi, an ideal that in numerical terms can be approached, but never reached.
But since then computers have calculated more digits of pi than could ever even be recited in a lifetime, let alone memorised, and now pi memorisation is only for the truly dedicated. The world champion is Akira Haraguchi, who in 2006 recited 100,000 digits of pi from memory at a public event near Tokyo. It took him 16hrs 30mins. This feat makes him the master pi-man, even though the Guinness Book of records has not validated his record. (The Pi World Records website has Chao Lu from China as number one, with a mere 67, 890 digits). Pi memorisation is difficult - and this is why people do it - since there is no pattern in the digits.
