Energy, light, information. Consider these terms as interchangeable. This is a good way to begin a study of the sun, that animates all forms of life.

Playing with toys can also be edifying. ‘Heliotropes’ (Greek helios=’sun’; trepein=’to turn’) are simple spinning devices that model the cycling of solar energy/light/information through a system. Each colored wheel, when set in motion, becomes like a tiny star — a fountain of life that sets the mind spinning!
