The advent of the computer has calculated the value of Pi up to a trillion digits.
National Pi Day
Larry Shaw a physicist at the Exploratorium in San Francisco created the Pi Day in 1988 as a commemoration of the mathematical constant and its ability to enthrall mathematicians down the ages. Pi day is celebrated on March 14 or 3/14 as 3, 1, and 4 are the first three digits of Pi. In 2009 the House of Representatives of the United States approved of the Pi day.
