What is the world record of memorizing pi?
In 1981, an Indian man named Rajan Mahadevan accurately recited 31,811 digits of pi from memory. In 1989, Japan's Hideaki Tomoyori recited 40,000 digits. The current Guinness World Record is held by Lu Chao of China, who, in 2005, recited 67,890 digits of pi.
Who memorized 70000 digits of pi?
While there are students who struggle to learn basic mathematics formulae, Rajveer Meena from the Mohocha village in Rajasthan holds the Guinness World Record for memorising 70,000 post-decimal digits of Pi. Rajveer achieved the feat back in 2015 when he was just 21 years old.
Is pi an infinite?
Pi is a number that relates a circle's circumference to its diameter. Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That's because pi is what mathematicians call an "infinite decimal" — after the decimal point, the digits go on forever and ever.
How long did it take Lu Chao to recite 67890 digits of pi?
Earlier, the record was held by Lu Chao. He had recited post decimal Pi values up to 67,890 digits in 24 hours and 7 minutes in 2005.

How many digits of pi can the average person remember?
Thursday marks Pi Day, otherwise known as 3.14, which marks the ratio of a circle's circumference to its diameter. While the average citizen can easily remember the 3.14 ratio, the exact ratio practically has an infinite amount of numbers.
Can the exact number of pi ever be calculated?
π is an irrational number, meaning that it cannot be written as the ratio of two integers. Fractions such as 22/7 and 355/113 are commonly used to approximate π, but no common fraction (ratio of whole numbers) can be its exact value.
Who invented zero?
About 773 AD the mathematician Mohammed ibn-Musa al-Khowarizmi was the first to work on equations that were equal to zero (now known as algebra), though he called it 'sifr'. By the ninth century the zero was part of the Arabic numeral system in a similar shape to the present day oval we now use.
What is the 62.8 trillion digits of pi?
In a brand new mathematical record, the value of pi has been calculated to 62.8 trillion digits. This feat was achieved by swiss researchers who made a computer work for 108 days to get to this value. Their approximation beat the previous world record of 50tn decimal places, and was calculated 3.5 times as quickly.
What is the 50 trillion digits of pi?

How was pi discovered?
In 1665, English mathematician and physicist Isaac Newton used infinite series to compute pi to 15 digits using calculus he and German mathematician Gottfried Wilhelm Leibniz discovered. After that, the record kept being broken.
When was pi first used?
Mathematicians began using the Greek letter π in the 1700s. Introduced by William Jones in 1706, use of the symbol was popularized by Leonhard Euler, who adopted it in 1737. An eighteenth-century French mathematician named Georges Buffon devised a way to calculate π based on probability.
How long did it take Lu Chao to recite pi?

Do numbers repeat in pi?
“We love pi because it's an irrational number, and its trailing digits don't repeat.” Pi is an irrational number, sure, because it can't be expressed as a fraction or ratio. 22/7 will get you close to pi, but not quite there. When written as a decimal number, pi's digits wander off without repeating.
Who memorized 42195 digits of pi?
Hiroyuki Gotō (後藤 裕之, Gotō Hiroyuki, born in Tokyo, Japan) recited pi from memory to 42,195 decimal places at NHK Broadcasting Centre, Tokyo on 18 February 1995. This set the world record at the time, which was held for more than a decade until Lu Chao beat it in 2005.

Albert Einstein's birthday is on March 14 — 3/14 — which is celebrated as Pi Day.
Why is 3.14 called pi?
It was first called "pi" in 1706 by [the Welsh mathematician] William Jones, because pi is the first letter in the Greek word perimitros, which means "perimeter."
Who invented Pi Day?
March 14 marks Pi Day, an annual celebration of the mathematical sign pi. Founded in 1988 by physicist Larry Shaw, March 14 was selected because the numerical date (3.14) represents the first three digits of pi, and it also happens to be Albert Einstein's birthday.
