Archimedes accurately estimated the value of pi. He was also the Greek inventor that created the compound pulley and first device used for extracting water from below the surface of the earth as well.
Archimedes estimated the correct value of pi
Consider a distribution with an unknown parameter pi. If the true value of pi is not known but has been estimated, then the estimated value is usually denoted by pi-hat. This is to distinguish between a known parameter and an estimated one.
