Having barely passed high school physics, I surprised myself some time ago when I took on the daunting, thankless task of teaching a lesson about light, prisms and rainbows for a Hanukkah program in our community religious school. Hanukkah is a great religious celebration of the Jewish people’s victory over its oppressors during the Maccabean War against the Syrian Greeks in 165 BCE. Modern Jews’ readings of the story through the lenses of minority and smaller-nation status emphasize timeless values such as maintaining one’s identity and political freedom. Yet Hanukkah’s religious fame is also founded upon its core legend, the miracle of the Menorah lamp that remained lit in the holy Jerusalem temple despite an insufficient amount of olive oil, after the Maccabean War ended. Because light is so prominent a Hanukkah theme, I reasoned that talking a little about the physics of light and optics with families would be a cool way of emphasizing its symbolism: white light and the spectrum as metaphors for unity and diversity, waves and particles as symbols for the spiritual and the physical, common features of science as a window on God’s miracles. What could be so hard about such a lesson, especially for an experienced, fun loving, boundary bending religion teacher like me? What fun we would all have shining lights through prisms in a dark room, watching in amazement all the pretty rainbow colors on the ceiling.
