Humble pi: when math goes wrong in the real world

Losing track of time

Engineering mistakes

Little data

Out of shape

You can't count on it

Does not compute

Probably wrong

Put your money where your mistakes are

A roundabout way

Too small to notice

Units, conventions, and why can't we all just get along?

Stats the way I like it

Titloay Rodanm

Does not compute

So, what have we learned from out mistakes?
