In 1914, Indian mathematician Srinivasa Ramanujan published a short paper detailing several unusual formulas for calculating ...

A new study finds that a century-old infinite series for calculating π discovered by Indian mathematician Srinivasa Ramanujan can be applied in other corners of physics. The study explained that ...

"It took 108 days to calculate with the Chudnovsky algorithm, and another 14 hours to verify the last 32 digits with the BBP algorithm. The Pi calculation program, y-cruncher, requires you to decide ...

March 14, 15:09:02. This date and time correspond to the first six decimal places of pi (π), the infinitely long number that begins ‘3.141592…’. It was created to commemorate ‘Pi Day (π-day)’. Pi ...

This pi day, we can write down more digits of the famous irrational number than ever before. An extra 9 trillion digits after the decimal point have been discovered, smashing the previous world record ...

It was in the year 1914 that Indian mathematician Srinivasa Ramanujan came to Cambridge with a notebook filled with 17 extraordinary infinite series for 1/π. They were not only efficient but also gave ...

Most of us first hear about the irrational number π (pi) – rounded off as 3.14, with an infinite number of decimal digits – in school, where we learn about its use in the context of a circle. More ...
