<div>The Eratosthenes Experiment</div><div><br></div><div>Eratosthenes was born in the country we now call Lybia, but in those days was called Cyrene.</div><div>Eratosthenes will always be remembered for the calculation of the Earth's circumference circa 240 BC, using trigonometry and knowledge of the angle of elevation of the Sun at noon in Alexandria and Syene (now Aswan, Egypt). The calculation is based on the assumption that the Earth is spherical and that the Sun is so far away that its rays can be taken as parallel.</div><div>Eratosthenes' experiment was one of the most important experiments in antiquity and his estimate of the earth’s size was accepted for hundreds of years afterwards. It was, in fact, the most accurate estimate until Man was able to go to Space.</div><div><br></div>
