### You Make the World Round

*Music and Lyrics by Melissa Wrolstad*

You Make the World Round — Listen

Let me tell you all a story of an endless relation,

It’s a tried and true constant used in every single nation,

In their algebra, trigonometry, cylindrical integration,

It’s a half-tau irrational mathematical sensation, it’s…

3.14159, you take me to a sphere or a circle from a line, you’re

3.14159, you take me to a sphere or a circle from a line, you’re

Pi…. pi…. pi…. pi… you make the world round.

It’s in the circle of my pupil and the sphere of my eyes,

In the sun and the moon and the stars in the sky,

Used by the Coulomb, Einstein and Heisenberg guys,

People ask me, what’s this magic? And I tell them, “It’s Pi!” Oh,

3.14159, you take me to a sphere or a circle from a line, you’re

3,14159, you take me to a sphere or a circle from a line, you’re

Pi…. pi…. pi…. pi… you make the world round.

The ratio of a circumference to radius is how you are defined,

Like the artist formerly known as Prince you’re represented by a sign,

You’ve been known for hundreds and thousands of years by mankind,

Despite this mystery still surrounds you, which just blows my mind.

You’re incredibly irregular, yet altogether stable,

Sharing a name with a dessert, yeah you got a quirky label,

And your symbol looks like, a super-funky table,

But I love you pi, so I learn as many digits, as I am able, as I am able.

3.14159, you take me to a sphere or a circle from a line, you’re

3,14159, you take me to a sphere or a circle from a line, you’re

Pi…. pi…. pi…. pi…

Pi…. pi…. pi…. pi… you make the world round.
