The refraction of light agrees with the grand principle that Nature always uses the simplest means to accomplish its effects. From this principle, can be derived whenever light passes from one medium to another, the ratio of the sine of the angle of refraction to the sine of the angle of refraction equals the inverse ratio of the speeds at which light moves in each medium. But this "budget", this expense of action that Nature minimizes in the refraction of light, is it also minimized in the direct propagation and reflection of light? Yes, it always has the smallest possible value.

George Orwell once wrote: "And it's not a matter of whether the war is not real or if it is. Victory is not possible. The war is not meant to be won, it is meant to be continuous. Hierarchical society is only possible on the basis of poverty and ignorance. This new version is the past and no different past can ever have existed. In principle the war effort is always planned to keep society on the brink of starvation. The war is waged by the ruling group against its own subjects and its object is not the victory over either Eurasia or East Asia but to keep the very structure of society intact."
Michael Moore
By being a racing driver you are under risk all the time. By being a racing driver means you are racing with other people. And if you no longer go for a gap that exists, you are no longer a racing driver because we are competing, we are competing to win. And the main motivation to all of us is to compete for victory, it's not to come 3rd, 4th, 5th or 6th. I race to win as long as I feel it's possible. Sometimes you get it wrong? Sure, it's impossible to get it right all the time. But I race designed to win, as long as I feel I'm doing it right.

The empire of Saturnus is gone by;
Lord of the secret birth of things is he;
Within the lap of earth, and in the depths
Of the imagination dominates;
And his are all things that eschew the light.
The time is o'er of brooding and contrivance,
For Jupiter, the lustrous, lordeth now,
And the dark work, complete of preparation,
He draws by force into the realm of light.
Now must we hasten on to action, ere
The scheme, and most auspicious positure
Parts o'er my head, and takes once more its flight,
For the heavens journey still, and adjourn not.
Friedrich Schiller
If every day a man takes orders in silence from an incompetent superior, if every day he solemnly performs ritual acts which he privately finds ridiculous, if he unhesitatingly gives answers to questionnaires which are contrary to his real opinions and is prepared to deny his own self in public, if he sees no difficulty in feigning sympathy or even affection where, in fact, he feels only indifference or aversion, it still does not mean that he has entirely lost the use of one of the basic human senses, namely, the sense of humiliation.
Václav Havel
It is a fearful thing to hate whom God hath loved. To look upon another-his weaknesses, his sins, his faults, his defects is to look upon one who is suffering. He is suffering from negative passions, from the same sinful human corruption from which you yourself suffer. This is very important: do not look upon him with judgmental eyes of comparison, noting the sins you assume you'd never commit. Rather, see him as a fellow sufferer, a fellow human being who is in need of the very healing of which you are in need. Help him, love him, pray for him do unto him as you would have him do unto you.
