(A sermon based on Colossians 1:15-20 for the 2nd Sunday of Easter 2014) Last October, Amanda Fiegl of National Geographic asked National Oceanic and Atmospheric Administration (NOAA) meteorologist Stephen Corfidi why some sunsets are so spectacularly colorful . Here is his explanation: When a beam of sunlight strikes a molecule in the atmosphere, what's called "scattering" occurs, sending some of the light's wavelengths off in different directions. This happens millions of times before that beam gets to your eyeball at sunset. The two main molecules in air, oxygen and nitrogen, are very small compared to the wavelengths of the incoming sunlight—about a thousand times smaller. That means that they preferentially scatter the shortest wavelengths, which are the blues and purples. Basically, that's why the daytime sky is blue. The daytime sky would actually look purple to humans were it not for the fact that the sensitivity of our eyes peaks in the middle [gre...
