Title. observation that a Ramanujan series for 1=ˇN, if truncated after p 1 terms for a prime p, seems always to produce congruences to a higher power of p. The formulas below are taken from [22]: Xp 1 n=0 (1 4) n(1 2)3 n (3 4) n 24n (1)5 3 + 34 n+ 120 2 3p2( mod p5) (1.12) pX1 n=0 (1 4) n(1 2) 7 n(3 4) n 212n (1)9 21 + 466n+ 4340n2 + 20632n3 + 43680n4? 21p4( mod p9): (1.13) By Ramanujan's theory (explained in my blog post linked above) we can find infinitely many series of the form $$\frac{1}{\pi} = \sum_{n = 0}^{\infty}(a + bn)d_{n}c^{n}\tag{1}$$ where $a, b, c$ are certain specific algebraic numbers and $d_{n}$ is some sequence of rationals usually expressed in terms of factorials. 7 digits!!! In a famous paper of $1914$ Ramanujan gave a list of $17$ extraordinary formulas for the number $\pi$. In this note we explain a general method to prove them, based on an original idea of James Ramanujan pi formula.
