For the next hour I will be listening to Dr Karl on JJJ

Do it! Do it now! This bloke knows the answer to everything. It's science made accessible. He is my hero.

Update If you know why the sky is blue, go to http://www.abc.net.au/science/k2/stn/default.htm#questions and tell Dr Karl.

When he doesn't know the answer he says "F.I.I.K."

FIIK?

Um...the sky is blue because that's the part of light not absorbed by the air molecules. Then there's the relative angle of light to viewer POV to take into consideration, hence sky is darker blue right above and lighter blue at the horizon.

Also, a sunset appears red because red portion of white light has the longest wavelength, therefore it travels the furthest. This is also why a stop light is red, because you will see it before any other light.

A lot of people C&P'd text from How Stuff Works onto his guestbook, so that was sort of answered.

So, did you listen?

FIIK=Fucked If I Know.
