Mathematics resources for children,parents and teachers to enrich learning. The 20th Century › In the 20th century, there have been two important developments: – the invention of electronic computers – the discovery of much more powerful formulas for pi › In 1910, the great Indian mathematician Ramanujan discovered the following formula for pi: 1 𝜋 = 2 2 9801 𝑛=0 ∞ 4𝑛 !. where and. In the case s = 2, the Hardy proof is no longer even formally correct. These formulas are interesting since the forms 1+i*sqrt(7))/2 and 1-i*sqrt(7))/2 figure prominently in the proof of the Ramanujan-Nagell Theorem (see below link, "The Ramanujan-Nagell Theorem: Understanding the Proof"). As a 10-year-old, he discovered his own formulas for the digits of Pi. On the other hand, among all the proofs of the irrationality of pi, Lambert's proof is probably the most "natural" one, the one that's easiest to motivate and explain, and one that's ideally suited for the sort of animations that I do. Hardy and Ramanujan came up with such a formula.
