“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."”

“Writer: I don’t know whether you've ever looked into a miner's eyes – for any length of time, that is. Because it is the loveliest blue you've ever seen. I think perhaps that's why I live in Ibiza, because the blue of the Mediterranean, you see, reminds me of the blue of the eyes of those Doncaster miners.”

“We have seven colours — violet, indigo, blue, green, yellow, orange and red (Roy G. Biv). Our atmosphere has a number of particles and when light falls on them, it gets scattered. With blue colour having less wavelength and more scattering qualities, it scatters and makes the sky blue. While red colour has opposite qualities than blue so traffic lights are of this colour.”

Jayant Narlikar (1938) Indian physicist

His observations on the "strange events in our solar system" and as to why the sky looked blue and red colour was used in traffic lights to signal to vehicles to stop.

“If you ask anyone why they are driven, it’s not just money, it’s not just a need to prove themselves, it’s a combination of things, and for us if we can get women to look at themselves in terms of shape, not size, if Suze and I achieve that as our little gravestone thing, then that would be a fucking big achievement.”

“I never saw a man who looked
With such a wistful eye
Upon that little tent of blue
Which prisoners call the sky.”

“…we see a number of sophisticated, yet uneducated, theoreticians who are conversant in the LSZ formalism of the Heisenberg field operators, but do not know why an excited atom radiates, or are ignorant of the quantum theoretic deerivation of Rayleigh's law that accounts for the blueness of the sky.”

“I think the most important thing for young people is that they're not trapped in the past. And human progress is driven by looking at a problem with fresh eyes, with new eyes. […] And that's the power of young people, is asking why.  Little kids, they naturally do that, right? When you talk to a four-year-old or a five-year-old, six-year-old, you tell them to do something -- "Why?" "Why?" And sometimes, as parents, we try to say, "because I told you so." And we don't want to talk about it, right? But that impulse to ask why is actually what drives human progress. […] Vision is important, but then you also have to have the persistence to keep working to make progress. And I always tell young people to have big dreams, but then also be willing to work for those dreams. It's not going to come right away.”

“The new discovery that I have made in painting is the following. There are chords of colors, let's say a certain red and green, which move, shimmer when you look at them. Now if you're looking at a tree in a landscape, you can either look at the tree, or at the landscape, but not both, because of the stereoscopic effect. Now, when you are painting something three-dimensional, the chromatic sound which shimmers is the three-dimensional effect of colour, and when you paint a landscape, and the green foliage shimmers a little with the blue sky showing through it, that happens because the green is on a different plane from the sky in nature too. Finding the space-shaping energies of colour, instead of contenting ourselves with a dead chiaroascuro, is our finest task.”

“And our little girl — Tricia, the 6-year old — named it Checkers. And you know, the kids, like all kids, love the dog and I just want to say this right now, that regardless of what they say about it, we're gonna keep it.”

Richard Nixon (1913–1994) 37th President of the United States of America

1950s, Checkers speech (1952)
Context: p>That's what we have and that's what we owe. It isn't very much but Pat and I have the satisfaction that every dime that we've got is honestly ours. I should say this — that Pat doesn't have a mink coat. But she does have a respectable Republican cloth coat. And I always tell her that she'd look good in anything.One other thing I probably should tell you because if we don't they'll probably be saying this about me too, we did get something — a gift — after the election. A man down in Texas heard Pat on the radio mention the fact that our two youngsters would like to have a dog. And, believe it or not, the day before we left on this campaign trip we got a message from Union Station in Baltimore saying they had a package for us. We went down to get it. You know what it was. It was a little cocker spaniel dog in a crate that he'd sent all the way from Texas. Black and white spotted. And our little girl — Tricia, the 6-year old — named it Checkers. And you know, the kids, like all kids, love the dog and I just want to say this right now, that regardless of what they say about it, we're gonna keep it.</p

“Joanna (Lady of Wales): Mama… why do I not look like you? Why do I have hair black like a crow?
Clemence: Because you take after him. That was all I asked of God, that I need not see him each time I looked into your face. Little enough to ask, I should think. But we do pay and pay for our sins, it seems, and you grow more like him with each day that passes.”
