Using highway signs to calculate pi to the 50th digit

On March 14, also known as Pi Day by the number lovers and math wizards in our lives, we're calculating pi to the 50th digit using numbered highway signs from across Arizona. 

For some of us, this video is the closest we get to using pi in our daily lives. For others, like ADOT engineers, pi is more than a mathematical constant, it's also regularly used when designing and building highway structures.
