Computers are getting faster with exponential speed. Today’s computers are doing such big calculations which seemed nearly impossible at once. Google Cloud Employee, Emma Haruka Iwao breaks her previous record that she made by calculating the 31.4 Trillionth digit 3 years ago in 2019. Now, using the same y-cruncher program, Emma calculated 100 trillion digits of Pi, and the 100 Trillionth digit was known to be zero.
For computers, it took around 157 days to calculate the 100 Trillionth digit of Pi. Calculations started in mid-October, 2021 and finished in March 2022. It was going more than twice as fast. Emma Haruka Iwao told in detail in the blog that she used the same techniques, and tools for the calculations but it was Google Cloud’s improved, fast, and secure hardware that made it possible.
You may be shocked to know, how much data was processed in the calculations?
Data processed in record breaking calculation
19,000 TB of data was processed during the first record-breaking calculation of 2019, and this time, in the calculations of 100 Trillion digits of Pi, about 82,000 TB of data was processed.
How big is one hundred trillion?
To estimate such a big number of 100 Trillion, you may imagine the height of a stack of 100,000,000,000,000 (one hundred trillion) one-dollar bills that measure 6,786,616 miles. This would reach from the earth to the moon and back 14 times as told in this blog about grasping large numbers.
What is Pi?
If you don’t know what Pi is? Then we must tell you that Pi is the value of the ratio of the circumference of any circle to the diameter of that circle. It is an irrational number which means you can’t express it as the ratio of the two numbers.
According to Wikipedia, Around 250 BC, the Greek mathematician Archimedes created an algorithm to approximate π with arbitrary accuracy. Many people and sources say he was the first person to do this. It is a very important number in mathematics that a day from the year is dedicated to pie. This day is 14 March. Starting three numbers of the Pi resembles this date i.e. 3.14 resembles 14 March(3rd month of the year).
Pi day was founded in 1988 by Larry Shaw, an employee of the Exploratorium. In schools, colleges, engineering, or mathematics Institutions, People celebrate this day by eating pie, organizing competitions related to Pi such as calculating or memorizing the value of Pi to as many numbers as possible etc.
