As an architect, astronomer, medical imaging specialist, or pilot, you will likely use orbits and conic sections to make calculations. Early astronomers believed that Earth revolved around the sun in a circular orbit, but Johannes Kepler discovered it actually revolved in an elliptical orbit.

If you would like to borrow an example, you might consider projections of the Earth onto a flat surface and the conic sections involved
