why is the sky blue?

Sometimes you won't ask so much about it
when the thing is to be in such a way
since you are exposed to it for the very first time
but have you really ever wondered why the sky is blue?

Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Closer to the horizon, the sky fades to a lighter blue or white. The sunlight reaching us from low in the sky has passed through even more air than the sunlight reaching us from overhead. As the sunlight has passed through all this air, the air molecules have scattered and rescattered the blue light many times in many directions. Also, the surface of Earth has reflected and scattered the light. All this scattering mixes the colors together again so we see more white and less blue.

I'm not sure if I did well,
at least I think I had a great conversation with them,
using my broken English and inaccurate accent,
trying my best to answer all questions which they had raised.
Okay, I admit I'm kinda boring and lame. I'm sorry :D

Good Luck, Edison.
Exams are on Thursday and Friday.
It's game time after that.
"I was much inspired by the HK drama."
"Stop watching drama, Edison :P"
"Do you have a girlfriend, Edison?"
"No. I don't have a girlfriend."
"That's why. You should get a contact lens then they will come to you :P"
They are great people, GREAT if I could work together with them.

I don't deserve the word,
it makes me feel guilty.
