pi

pi
is three point one four
and the standard number to apply
when hunting the secrets behind circle’s door
that well-known number holds the only way to measure
the ratio of circle’s circumference to its diameter, a constant
discovered by the ancients, Ahmes and Archimedes, who conjured
from circle’s empty heart, equations, figures, and diagrams to enchant
three point one four from its deep slumber, but it was Leonhard Euler,
who, in seventeen thirty six, scanned the Greek alphabet and found
the dash running on two legs was how he would always refer
to three point one four, so the little letter was crowned
and from mathematics to engineering it has
a steady job, for these studies rely
on the letter known as
pi
