Pi Day

16 March 2015

Last Saturday, 3/14/15 (using the US date format), was a very special pi day! The date matches the first five digits of pi. To mark the day, Dr Tudur Davies, a Coleg Cymraeg funded Welsh medium lecturer at the Department of Mathematics contributed an article to the BBC “Cymru Fyw” website. In it he discussed the connection that pi has with Wales. Did you know that the first person to use the Greek letter π  to denote 3.14159... in print was Welsh mathematician William Jones?
