They also had invented decimal notations ages before Europe. The simple reason for this was the fact that they had invented the concept of zero well ahead of their European counterparts. Long before the Europeans hit on the concept of Pi, the Chinese were already well aware of it. The Chinese were well ahead of Europe with regards to Pi Of course, they could be evil Pi-hating maniacs. Tau divided by 4 also represents the angle of a quarter of a circle very effectively. This is because you can, for example, multiply tau with the radius of a circle to calculate its circumference more intuitively. Some Pi-heathens believe that tau (2 π) might actually be better suited for circle calculations. Despite being loved by many math enthusiasts, and us at IE, love might indeed be blind. The very fundamental practical use of Pi has been in debate for quite some time. Pi might not be that useful Source: Rex Sorgatz/Flickr ' The vertical height of the pyramids have the same relationship with the perimeter of their base as the relationship between a circle’s radius and its circumference.'. In fact, it is still believed today that the pyramids of Giza were built on the very principles of Pi. The size of the circle was not important, but they always appeared to get the same answer - roughly 3.14.īecause of this, it became part of Egyptian mythology. Like today, the ancients had discovered a magical ratio between the circumference of a circle and its diameter to be equal. The first recorded evidence of its existence was around 4,000 years ago in Ancient Egypt and Babylonia. Pi is not a new concept - not by a long shot!

In order to preserve his concentration, Mr. The legend, Rajveer Meena of VIT University, Vellore, India, took no less than 10-hours to achieve the feat. Rajveer wore a blindfold throughout the entire recall, which took nearly 10 hours #PiDay /mHf3OJRcXCīack in 2015, one chap actually managed to remember and recite Pi to 70,000 decimal places.

Here's just a few pages from Rajveer Meena's evidence of his attempt for the most decimal places of Pi memorised - 70,000. Some chap recited Pi to an incredible 70,000 decimal places Mike Keith, a devote Pilish-lover, even wrote an entire book in Pilish called ' Not a Wake.' 5. There is actually a language based on Piĭid you know there is actually an entire language based entirely on Pi? Called Pilish, the numbers of letters in successive words match the digits in Pi. The bill was duly debated, but most of the delegates believed that using the law to change a mathematical concept was inappropriate, to say the least. Edwin Goodwin proposed a bill to the state legislature and also copyrighted the idea in hopes of claiming royalties if he was successful. He argued that this would solve all the problems of its irrational nature and simplify future calculations that depended on the value of Pi.ĭr.

One Indiana doctor attempted to make it law to round Pi from 3.14 etc.

Have you heard the story of the time that it was attempted to round up Pi using the full force of the law? Well, it actually happened back in 1897. It was once attempted to round up Pi using the force of the law Source: Woody Hibbard/Flickr In fact, to date, Pi has been calculated to over 22 Trillion digits.īecause of this, it follows that we could never truly calculate the circumference or area of a circle. It can't be expressed as a proper fraction that has a definitive end.įor this reason, it just keeps going and going forever. This means that the number of decimal places for Pi is, in fact, never-ending. This is because Pi is what is called an irrational number. The exact value for Pi can, famously, never actually be calculated in full. We will never be able to accurately calculate the area or circumference of a circleĪs useful as Pi is as a mathematical concept, it is not perfect. The symbol has now been in use for well over 250 years but was actually popularised by another mathematician, Leonhard Euler. It turns out that the very symbol for Pi was first introduced by a Welsh mathematician called William Jones in 1706. Great singers, great sportsmen, cawl, welsh cakes, a flag with an actual dragon, legendary archers, a beautiful countryside, and a rich history.īut there is one lesser-known piece of Welsh history that needs to be celebrated a lot more.
