American Pi Find, find the value of pi. Starts 3 point 1 4 1 5 9. Good ol’ boys gave it a try, But the decimal never dies, The decimal never dies.....

American Pi In the Hebrew Bible we do see The circle ratio appears as three, And the Rhind Papyrus does report four- thirds to the fourth, And 22 sevenths Archimedes found with polygons was a good upper bound. The Chinese got it really keen: Three-five-five over one thirteen!

More joined the action with arctan series and continued fractions. In the seventeen-hundreds, my oh my, The English coined the symbol Pi Then Lambert showed it was a lie To look for rational pi He started singing....

10
Now in these computer times, We test the best machines to find to a billion places That so far lack pattern’s traces. It’s great when we can truly see Math as human history –

11
That adds curiosity... Easy as ! Let’s all try singing...
