Why is the color of the sky blue?

Hello World!

Ha!
I choosed that title because it's the name of the first program whenever you begin learning a particular computer language. And I guess its as good as any. As a first post that is.
So why mundane physics?
Well, first off, to warn would be readers (if there would be any), im not an expert in physics. Hell, i've been trying to finish my graduate studies for several years now. Hopefully this would be my last year as a masters student so that i can go and maybe take up my doctorate or maybe make more money...
So what can you expect from this blog? Random thoughts about physics. Maybe, ill talk about quantum mechanics, relativity and classical physics.
So there.
Hi to all of you!
