Theorist inspires educational day.

Byline: GARETH WYN WILLIAMS Daily Post Reporter garethwyn.williams@trinitymirror.com

NORTH Wales pupils have been helping themselves to a giant slice of Pi in celebration of one of the world's most iconic maths theories and its unique connection to our nation.

Wales has a unique claim to the maths phenomenon that started in 1706, as William Jones from Llanfechell on Anglesey was the first person to use the Greek letter p or pi to represent the mathematical constant to calculate the ratio of the circumference of a circle to its diameter..

To mark this, Pi Day Cymru will be sweeping the nation today (Monday) and will see people of all ages involved in a range of activities aimed at inspiring them to embrace more uses of maths in everyday life.

meritus ity, he The day is the brainchild of Professor Gareth Fffowc Roberts, Emeritus Professor at Bangor University, who last year received the backing of the Welsh Government to establish the date as an official day of national celebration in Wales.

Pi, most commonly approximated as 3.14159, is an irrational number,and not even the most powerful computers WILLIAMS ot putplayed have managed to calculate its exact value.

But for years, people have had fun trying to memorise as many of its digits as they can.

The Americans have been celebrating National Pi Day since 1988 and other countries have followed suit since then, acknowledging the pivotal role pi has played in engineering and technology.

noloY Ys kbPw in ga use The Year 8 and 9 pupils at Ysgol Friars in Bangor kicked off the celebrations by hosting their very own Pi in the Sky session last week - which saw pupils involved in a one-off stargazing workshop looking at uses of pi in outer space. They were led by the school's Anglesey man Jones head of maths, Chris Parry, deputy head and physics teacher, David Healey, and experts from Techniquest Glyndwr in a special lesson on how the iconic maths theory has helped mankind discover the universe.

Mr Parry said: "Maths can sometimes be perceived as just a classroom subject but the truth is, when it comes to succeeding in all aspects of our everyday lives, it's impossible to live without it in the real world.

"The session has been brilliant in helping students to get enthused about the practical application of calculations like pi and encouraging them to really think about what life would be like without them - which in truth, is extremely difficult."
