Секоја рамноденица ни е предвидена за Ератостенов експеримент. ERATOSTHENES' EXPERIMENT ERATOSTHENES FROM SKOPJE FROM PS “DIMITAR MILADINOV” We conducted our experiment when the Sun was at the zenith over the equator, exactly at noon local time, meaning when the Sun’s rays were falling vertically on locations around the equator. Beforehand, we determined the distance from our school to the equator. We measured the shadow of a vertical stick 100 cm long. During the spring and autumn equinoxes, the Sun’s rays fall vertically on the equator, so a vertically placed stick at the equator casts no shadow. That is our “Aswan (Syene),” and Skopje, in this case, represents Alexandria. We determined solar noon using the Local to Solar Time Converter . To calculate it, it’s enough to input the geogr...
