The U.S. population has reached a nerdy and delightful milestone.
Shortly after 2:29 p.m. on Tuesday, August 14, 2012, the U.S. population was exactly 314,159,265, or pi (π) times 100 million, the U.S. Census Bureau reports. The U.S. Census Bureau's Population Clock projects the real-time size of the U.S. population based on monthly population estimates.
Pi (π) is a unique number in multiple ways. For one, it is the ratio of a circle's circumference to its diameter. It is also an irrational number, meaning it goes on forever without ever repeating itself. Are you remembering how much you loved geometry class? You can check out pi to one million places here.
