relation created by Mario Belloni

The Easy Java Simulations Modeling and Authoring Tool is needed to explore the computational model used in the EJS Gnomon Model.


Gnomon Model covers the same topic as Eratosthenes Model
relation created by Mario Belloni

The Eratosthenes model displays the shadows cast by two gnomons (sticks) at different locations on Earth. This simulation can be used to help illustrate how Eratosthenes was able to measure the diameter of Earth using the shadows cast by two gnomons.
