We reviewed Jared's assignment for last weekend on FM vs AM radio, and I quizzed him (orally) on the differences between the two forms of radio transmission. The background for this exercise was to give a more in-depth appreciation of electromagnetic radiation in preparation for future lessons. We then proceeded to discuss the dawn of astronomy with the Babylonians and Egyptians, and the importance of following the same cycles over many generations. We worked our way up to Nicholas Copernicus and the shift from the geocentric to the heliocentric model of the Solar System (Universe, as it was then) and discussed the implications of Galileo Galilei's discovery of the moons of Jupiter. I was very impressed with Jared's curiosity on the topics we touched upon, and in fact welcomed his questions.
