Skeptical Quote of the Week (1:25:09)

If a little kid ever asks you just why the sky is blue, you look him or her right in the eye and say, "It's because of quantum effects involving Rayleigh scattering combined with a lack of violet photon receptors in our retinae."  – Phil Plait (1964-present), "the Bad Astronomer"  Phil discusses this quote in the article Meme, Myself, and Eyes: How to explain why the sky is blue

(Transcriptionist's note: Steve's comments line up well with scaffolding and Lev Vygotsky's zone of proximal development.)
