This is the astonishing moment a youngster from Gloucestershire broke his own world record for the reciting pi - live on national television.
Just a few days ago Charley Thomas, 10, left jaws on the floor when he remembered the infinitely-long number to a massive 220 decimal places.
But then this morning he went not one, but 38 better live on Good Morning Britain in front of hosts Piers Morgan and Susanna Reid. He told Susanna beforehand that he one day hopes to recite the number to 10,000 decimal places.
Charley, a Year 5 pupil at Stonehouse's Wycliffe Preparatory School has now gone viral twice as videos of both his successful record attempts have been widely shared.
You can see his effort in ITV's video below:
“I’m not very good at at standing up and doing something in front of people so I was a bit nervous at assembly,” said Charley of his first attempt. “I had rehearsed at home and knew I could get to 220 places. I really like maths.”
Piers nicknamed him 'Little Einstein' on this morning's show after his remarkable feat.
Pi is used in engineering, physics, supercomputing and space exploration - because its value can be used in calculations for waves, circles and cylinders.
“This is an incredible achievement and one that no Wycliffe pupil has done before,” said Headmaster Adrian Palmer.
“It is fitting that on the same day Emma Haruka Iwao, a Google employee from Japan, calculated the value of the number pi to a new world record length of 31 trillion digits, far past the previous record of 22 trillion.
“Charley received a standing ovation for his efforts in assembly and it was so richly deserved.”
A range of pi activities and challenges were organised for pupils to mark Pi Day (14 March - "3.14" in American date notation). These included creating Pi art, writing nonsense verse in “PiLish” and finding evidence of circular buildings.
