Emma Haruka Iwao (born April 21, 1984) is a Japanese computer scientist and cloud developer advocate at Google.[5][6] In 2019 Haruka Iwao calculated the then world record for most accurate value of pi (π); which included 31.4 trillion digits, exceeding the previous record of 22 trillion.[7][8][9][10][11] This record was surpassed in 2020 by Timothy Mullican who calculated 50 trillion digits,[12][13] but she reclaimed the record in 2022 with 100 trillion digits.[14] The record was surpassed by a computer storage company in 2024, reaching roughly 105 trillion digits.[15] She identifies as queer.[16]

Early life and education

[edit]

As a child, Iwao became interested in pi.[7] She was inspired by Japanese mathematicians, including Yasumasa Kanada.[17] She studied computer science at the University of Tsukuba, where she was taught by Daisuke Takahashi.[6][5] She was awarded the Dean's Award for Excellence in 2008, before starting graduate studies in computing. Her master's thesis considered high performance computer systems.[6] After graduating, Iwao took on several software engineering positions, working on site reliability for Panasonic, GREE and Red Hat.[5]

Career

[edit]

Iwao joined Google as a Cloud Developer Advocate in 2015.[7] She originally worked for Google in Tokyo, before moving to Seattle in 2019.[2] Iwao offers training in the use of the Google Cloud Platform (GCP), as well as supporting application developers.[18][19][20] She works to make cloud computing accessible for everyone, creating online demos and teaching materials.[21]

In March 2019 Iwao calculated the value of pi to 31,415,926,535,897 digits (Equal to ⌊π × 1013⌋), using 170 terabytes (TB) of data.[7][17][22][1][23] The calculation used a multithreaded program called y-cruncher using over 25 machines for 121 days.[7][24][21]

In March 2022 she extended the world record to 100 trillion digits of pi.[25]
