Pi can be calculated using a random sample of darts thrown at a square and circle target.

The area of a circle is pi times the radius squared. This is half of a circle with a radius of 1 (no units) such that it would have an area of pi/2.

On this day of numerical glory, get to know pi in an unusual way: using the elastic collision of two different masses and a wall.

Using that short version of pi is easy and works fine for simple problems. If you’ve ever used the pi button on a calculator, that probably uses pi rounded to ten decimal places.

Swiss researchers said on Monday they had calculated the mathematical constant pi to a new world-record level of exactitude.

Who was the first person to calculate pi? The first person to realise that, hang on, when you divide the circumference of a circle by its diameter, you always seem to get the same number, namely ...

Running on a real 4004 with peripheral hardware simulated inside an STM32, it spent 3 hours, 31 minutes and 13 seconds calculating 255 digits of pi, and correctly, too.

This Pi Day, try calculating everyone’s favourite mathematical constant using balls and a cardboard tube, thanks to a mathematical trick involving the balls’ masses ...

Talk about perfect timing — a Google engineer revealed she broke the world record for calculating pi on National Pi Day.

Google Cloud Developer Advocate Emma Haruka Iwao has set a new world record for calculating the most digits of pi ever, demonstrating the capabilities of Google Cloud infrastructure.

Google engineer Emma Haruka Iwao has calculated pi to 31 trillion digits, breaking the world record.

Iwao and a Google team computed Pi to 31.4 trillion decimal places or Pi multiplied by 10 to the 13th power, ousting the previous record set in 2016 of 22.4 trillion digits.
