First 10,000 digits of Pi.
The perfect gift for the math geek, this nerdy design features the first 10,000 digits of the number and mathematical symbol, Pi. This number is a cornerstone in many branches of mathematics, and is formed by the division of the circumference of a circle by its diameter. This seemingly simple division yields a number that does not repeat itself, or an irrational number. It has been explored, up to billions of digits, and is a source of wonder for mathematicians. Show off your geekiness with the Pi design.
