Earth – Darryl E Berry Jr

This article is a continuation of my Earth Measurement 1, where I used the method of Eratosthenes, as taught in my introductory astronomy class, to measure the circumference of the Earth.

We can calculate both the height of the Sun and the angular height of the Sun for a flat Earth, given the information from Earth Measurement 1. Simply, sunsets demonstrate that the Earth is a globe.
