Emma Haruka Iwao (born April 21, 1984) is a Japanese computer scientist who works at Google. She is famous for calculating the most accurate value of pi (π). In 2019, she set a world record by finding 31.4 trillion digits of pi. Later, in 2022, she broke her own record by calculating 100 trillion digits! This amazing achievement shows her skill in using powerful computers.
Early Life and Learning
As a child, Emma Haruka Iwao became very interested in the number pi. She was inspired by other Japanese mathematicians. She decided to study computer science at the University of Tsukuba. Computer science is about how computers work and how to make them do amazing things.
In 2008, she received a special award for her excellent studies. After that, she continued her learning in computing. Her master's project focused on making computer systems work very fast. Before joining Google, Iwao worked as a software engineer for companies like Panasonic and Red Hat.
Her Work at Google
Emma Iwao joined Google in 2015. She works as a Cloud Developer Advocate. This means she helps people understand and use Google's cloud computing services. Cloud computing is like using powerful computers over the internet instead of owning them yourself.
She teaches others how to use the Google Cloud Platform (GCP). She also helps app developers. Her goal is to make cloud computing easy for everyone. She creates online lessons and helpful materials.
Calculating Pi's Digits
In March 2019, Emma Iwao made history. She calculated the value of pi to 31,415,926,535,897 digits. That's over 31 trillion digits! To do this, she used a huge amount of data, about 170 terabytes. A terabyte is a very large unit of computer data storage.
The calculation took 121 days. She used a special computer program called y-cruncher. It ran on more than 25 different computers at the same time. This process is called multithreading.
In March 2022, she broke her own world record. She extended the calculation of pi to an incredible 100 trillion digits! This shows how powerful modern computers are and how skilled Emma Iwao is.
