A coloring book for kids from kindergarten to college. This book exposes younger students to concepts they normally wouldn't see until higher grades. And it can give advanced students some new views of concepts they're already familiar with.
Johannes Kepler had discovered planets move about the sun in elliptical orbits with the sun occupying a focus of the ellipse. We now know the paths of orbiting bodies are conic sections (the ellipse, parabola, and hyperbola). This coloring book takes a look at conic sections as well as orbits in outer space.
