 One of his most famous formulas is an infinite series for \( \frac{1}{\pi} \):
 
-$\frac{1}{\pi} = \frac{2\sqrt{2}}{9801} \sum_{n=0}^{\infty} \frac{(4n)!(1103 + 26390n)}{(n!)^4 396^{4n}}$

 This series converges extraordinarily rapidly, making it highly efficient for calculating \( \pi \) to many decimal places. In 1985, William Gosper used this formula to compute \( \pi \) to 17 million digits.
