A Quote by Phil Plait

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.'
My wife could turn to me and she may say, 'Why do you love me?' And I can with all honesty look her in the eye and say, 'Because our pheromones matched our olfactory receptors.'
The fundamental importance of the subject of molecular diffraction came first to be recognized through the theoretical work of the late Lord Rayleigh on the blue light of the sky, which he showed to be the result of the scattering of sunlight by the gases of the atmosphere.
Bean finds the best apple in our tree and hands it up to me. "You know what this tastes like when you first bite into it?" she asks. "No, what?" "Blue sky." "You're zoomed." "You ever eat blue sky?" "No," I admit. "Try it sometime," she says. "It's apple-flavored.
The water is this marvellous blue. It’s so blue that once you see it you realise you’ve never seen blue before. That other thing you were calling blue is some other colour, it’s not blue. This, this is blue. It’s a blue that comes down from the sky into the water so that when you look in the sea you think sky and when you look at the sky you think sea.
I let my head fall back, and I gazed into the Eternal Blue Sky. It was morning. Some of the sky was yellow, some the softest blue. One small cloud scuttled along. Strange how everything below can be such death and chaos and pain while above the sky is peace, sweet blue gentleness. I heard a shaman say once, the Ancestors want our souls to be like the blue sky.
I'm not falling anymore. That's what L says, and she's right. I guess you could say I'm flying. We both are. And I'm pretty sure somewhere up there in the real blue sky and carpenter bee greatness, Amma's flying, too. We all are, depending on how you look at it. Flying or falling, it's up to us. Because the sky isn't really made of blue paint, and there aren't just two kinds of people in this world, the stupid and the stuck. We only think there are. Don't waste your time with either-with anything. It's not worth it.
When somebody asks for a favor involving information, if you don't know him or can't verify his identity, just say no.
It is to be emphasized that no matter how many [amplitude] arrows we draw, add, or multiply, our objective is to calculate a single final arrow for the event . Mistakes are often made by physics students at first because they do not keep this important point in mind. They work for so long analyzing events involving a single photon that they begin to think that the arrow is somehow associated with the photon [rather than with the event].
I don't know that it's a lack of creativity so much as it is , a lack of resources. And maybe a little bit of a lack of will but when you look at what fills every hour, let's just take CNN as an example, not because I think they're particularly egregious, but, they're sort of the ongoing hour, hour, hour. Why do they give us bulletins every single day on the latest poll? Very easy to cover a poll, right?
Once in a blue moon, everything will be right with the man in the sky, and when I start singing 'I Love a Rainy Night,' from out of nowhere, there will be lightning and thunder. I just say, 'Folks, we've got the best special effects guy in the world, so let's get wet together.'
If you look at photographers who say, "I hate digital photography," they all use Photoshop, even if it's to make the sky just a little more blue than it was. Manipulation is very discrete and because it's so discrete nobody cares about it anymore. People accept manipulated photographs, I think.
So, having found a lady, could you not have come to her aid, or left her alone? Why drag her into your foolishness?' 'Love,' he explained. She looked at him with eyes the blue of the sky. 'I hope you choke on it,' she said, flatly.
Typically in science, individual scientists make up their minds about scientific fact or theory one at a time. We don't take votes. We just don't vote on quantum mechanics, the theory of relativity, why the sky is blue, or anything else.
I don't want to wrong anybody, so I won't go so far as to say that she actually wrote poetry, but her conversation, to my mind, was of a nature calculated to excite the liveliest of suspicions. Well, I mean to say, when a girl suddenly asks you out of a blue sky if you don't sometimes feel that the stars are God's daisy-chain, you begin to think a bit.
...There are also those who inadvertently grant power to another man's words by continuously trying to spite him. If a man gets to the point where he can simply say, 'The sky is blue,' and people indignantly rush up trying to refute him saying, 'No, the sky is light blue,' then, whether they realize it or not, he has become an authority figure even to such adversaries.
When a photon comes down, it interacts with electrons throughout the glass, not just on the surface. The photon and electrons do some kind of dance, the net result of which is the same as if the photon hit only on the surface.
