SAN FRANCISCO, March 14 (UPI) -- U.S. celebrations for the math holiday Pi Day -- March 14, or 3/14 -- include a San Francisco "pi procession" where humans line up as the irrational number.

Pi Day, which celebrates the circumference of a circle divided by its diameter, is celebrated March 14 in honor of the number, which has an infinite number of digits but begins with 3.14, CNN reported Friday.

The San Francisco Exploratorium, where Pi Day was founded in 1988 by Larry Shaw, is holding a "pi procession" with each participant being assigned a number and lining up in order of pi's digits for a parade ending at the museum's "pi shrine," a pi sculpture with digits spiraling around it.

The city of Princeton, N.J., which is the hometown of Albert Einstein, whose birthday falls on Pi Day, is holding events including a walking tour of the late physicist's neighborhood, a pizza pie making contest, an Einstein lookalike competition and a contest to see who has correctly memorized the most digits of pi.

Meanwhile, in Chicago, the Illinois Science Council and Fleet Feet Sports is sponsoring a 3.14-mile walk/run Friday night with special Einstein-related discounts for anyone named Albert, Alberta or Albertina.

Officials with Boston's Museum of Science and the Seattle Children's Museum said they will also be offering Pi Day events for visitors.
