    en.wikipedia.org/wiki/Piphilology

    In 2004, Andrew Huang wrote a song that was a mnemonic for the first fifty digits of pi, titled "I am the first 50 digits of pi". [14] [15] The first line is: Man, I can’t - I shan’t! - formulate an anthem where the words comprise mnemonics, dreaded mnemonics for pi. In 2013, Huang extended the song to include the first 100 digits of pi ...

    BBP and BBP-inspired algorithms have been used in projects such as PiHex [4] for calculating many digits of π using distributed computing. The existence of this formula came as a surprise. It had been widely believed that computing the nth digit of π is just as hard as computing the first n digits. [1] Since its discovery, formulas of the ...
