Dear Measurerers,

Measurement is where the ideal world of math comes into contact with the real, physical world. And in the real physical world we can never be perfectly exact. Everything is an approximation–close, an estimate, good enough. 

Of course we strive to be as precise as we can, but like every other human endeavor, measurement is about finding a shared meaning that we can agree on. And when we do that, we can build things together.

Sincerely,

Mr. Heimbuck
