Pi (Greek: π) – the legendary mathematical constant which allows us to calculate all kinds of measurements of circles – is probably known to most people as just 3.14. However, it is actually an irrational number with an infinite number of decimals.

While trillions of decimals have been discovered by scientists, our humble Pi study mug offers you the first 1500. Each row has 75 decimals, and maybe over time you'll at least be able to memorize the first row!

Not your thing? Perhaps you know somebody who is into math and science – this could be the perfect gift for them!
