Emma Haruka Iwao

Imagine trying to count to a super, super, SUPER big number! That's kind of what Emma Haruka Iwao does, but with numbers that make up pi (π). Pi is a special number used in circles, and Emma is amazing at figuring out its digits. She's like a detective for numbers, finding more and more of them!

Emma has set records for finding the most digits of pi. First, she found 31.4 trillion digits! That's more than all the grains of sand on all the beaches in the world! Then, she found 100 trillion digits. That's like having a library with 100 trillion books, all filled with numbers!

Pi helps us understand circles, which are everywhere! From wheels on a bike to the shape of the Earth, circles are important. The more digits of pi we know, the more precise we can be when building things or understanding how things work in space. Emma's work helps scientists make super accurate calculations.

Emma doesn't use a pencil and paper for her number quests. She uses powerful computers! She works at a company called Google, where she helps people use amazing computer technology. Her brain is like a supercomputer, solving huge number puzzles.
