Casual Pi Day in United States 2023: Date, History, Facts, Activities

The planet commemorates Pi Approximation Day annually on July 22. This day is celebrated on July 22 because the fraction 22/7 is a close approximation of the value of Pi. In this instance, the numerator 22 indicates the date, whereas the numerator 7 indicates the month.

Pi is defined as the ratio of the circumference to the diameter of a circle and is approximately equal to 3.14159. Inputting the numbers into a calculator reveals that 22 divided by 7 yields an infinite number of answers. The numbers persist forever. As a result, Pi is considered an approximation, which is the rationale for today.

The background of Casual Pi Day

Since approximately 4,000 years ago, pi has been known in some form. It was used by the ancient Babylonians to calculate the diameters of circles, approximately 3.125. In approximately 250 B.C., one of the greatest ancient mathematicians, Archimedes of Syracuse, calculated pi for the first time. He found that pi fell between 3.1/7 and 3.10/71.

In the middle of the fifth century, another gifted mathematician, Zu Chongzhi, used arduous computations to recalculate pi. Chongzhi invented his method for calculating pi because the works of Archimedes had been seized and were unavailable in China at the time. Chongzhi and Archimedes were the first scientists to truly discover pi.

Utilising circumscribed and inscribed polygons, later mathematicians sought to enhance the precision of pi. This is how Archimedes first calculated pi, and it remained the most popular algorithm for pi computation for the next thousand years. Christoph Grienberger, an Austrian astronomer, performed the most precise calculation of pi using this method in 1630, arriving at 38 exact digits.

According to urban legend, Pi Day and Pi Approximation Day are inextricably linked, and Pi Day is celebrated annually on March 14 around the world. Since the value of Pi is 3.14, physicist Larry Shaw instituted Pi Day in 1988 at the “Exploratorium.” According to the “San Francisco Science Museum,” the date for Pi Day is March 14, which is 3.14, the value of Pi. The “United States House of Representatives” also supported Pi Day in 2009. In contrast, Pi Approximation Day is celebrated annually on July 22.

PI DAY RECESSIVE ACTIVITIES

Have many pies.

Remember that a pie is essentially a circle, so not only are you learning mathematics, but you’re also having fun while eating! Go on, delve in!

Participate in a contest

It has also been observed that many institutions and education classes hold competitions to determine which student can recall Pi to the most decimal places. Whoever knows the most digits of the given number wins a pie.

Do some entertaining challenge

The challenge of memorising as many digits of a number as possible is enjoyed by both students and mathematicians. Today, challenge a friend or relative to surpass your pi knowledge.
