This unending figure has always attracted philosphers, mathematicians, scientists, engineers and programmers ever since last 4 Millenia. A few intersting links of the efforts made by them are listed as below. Any addenda to the same are always welcome.

The numerical value of π truncated to 50 decimal places is:
3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510
Even long before computers have calculated π, memorizing a record number of digits became an obsession for some people. A Japanese man named Akira Haraguchi claims to have memorized 100,000 decimal places.
The Guinness-recognized record for remembered digits of pi is 67,890 digits, held by Lu Chao, a 24-year-old graduate student from China.
It took him 24 hours and 4 minutes to recite to the 67,890th decimal place of pi without an error
