ST. LOUIS (KMOX) –  3.14159265…ad infinitum.

Pi — the wonder number derived from the ratio of any Euclidean circle’s curcumference to its diameter — will be celebrated all this weekend at the St. Louis Science Center.

“We have activities so visitors can calculate Pi themselves using the same kind of methods that we’ve all used to calculate Pi for a long time,” explains Sarah Schoenlaub, gallery leader of physical science for the Science Center.

Many of those activities are designed for children — for instance M&Ms will be handed out so visitors can lay out a certain number around a circle, and along a line cutting that circle in two representing the diameter.

Divide the number around the circumference by the number across the middle, and you ought to get a close estimation of 3.14.

“They usually come pretty close,” Schoenlaub says.

They’ll also learn which is the better deal, one medium pizza or two small pizzas offered for the same price, by using Pi.

Schoenlaub encourages everyone, especially those with large groups of children, to come out to the Science Center Friday, Saturday or Sunday.

The highlight will be something called the Amazing Science Demonstration.

“We’ll have something special at 1:45 pm each day called ‘Science Goes Splat’,” explains Schoenlaub, who’s not ready to release more details just yet. “I can’t reveal too much, but at 1:59 (each day) something might happen during the show, so you’ll have to be there to check it out.”

While Pi Day will be observed this Friday, Saturday and Sunday at the Science Center — the rest of the world will celebrate on Pi’s own designated day, March 14th.
