  1. 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 . . . . .

  2. 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!

  3. 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 . . . .

  4. 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 . . . . .

  5. Late eighteen-hundreds, Lindemann shared why a circle can’t be squared • But there’s no tellin’ some people— • Can’t pop their bubble with Buffon’s needle, • Like the country doctor who sought renown • From a new “truth” he thought he found.

  6. The Indiana Senate floor • Read his bill that made p Four. • That bill got through the House • With a vote unanimous! • But in the end the statesmen sighed, • “It’s not for us to decide,” • So the bill was left to die

  7. Like the quest for rational pi. • They started singing . . . .

  8. 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 . . . . .

  9. The doctor’s p in the sky dreams • May not look so extreme • If you take a look back: • Math’maticians long thought that • Deductive systems could be complete • And there was one true geometry.

  10. Now in these computer times, • We test the best machines to find p 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 p! • Let’s all try singing . . .

  12. 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 . . . . .
