When the Air Force Technical Applications Center celebrated National Pi Day on March 14, Tech. Sgt. BreAnne Groth’s section was amazed when the noncommissioned officer in charge picked up a dry-erase marker and began writing out Pi in decimal form from memory. With ease, she surpassed 100 decimal points and stopped only because she ran out of room on the white board and had to get back to work. (U.S. Air Force Photo by Susan A. Romano)
