The heliocentric, or Sun-centered model, one of the most important revolutions in scientific thinking, allowed Nicholas Copernicus to calculate the periods, relative distances, and approximate orbital shapes of all the known planets, thereby paving the way for Kepler's laws and Newton's formation of gravitation. Recreating Copernicus's calculations could be an excellent topic for high school mathematics as the derivations use basic algebra, geometry, and trigonometry in a creative problem-solving setting.
