Some notable accomplishment and achievements in the 3rd Century BC are listed below:
invented the science of mechanics and hydrostatics discovered the laws of levers and pulleys, which allows us to move heavy objects using small forces invented one of the most fundamental concepts of physics ( the center of gravity ) calculated Pi to the most precise value known. His upper limit for Pi was the fraction 22/7. This value was still in use in the late 20th century, until electronic calculators finally laid it to rest discovered and mathematically proved the formulas for the volume and surface area of a sphere showed how exponents could
