Now I have to define what I mean by "action". When a material body is transported from one point to another, it involves an action that depends on the speed of the body and on the distance it travels. However, the action is neither the speed nor the distance taken separately; rather, it is proportional to the sum of the distances travelled multiplied each by the speed at which they were travelled.

The immaterial Blue colour shown at Iris Clert's in April [1958, together with Jean Tinguely ] had in short made me inhuman, had excluded me from the world of tangible reality; I was an extreme element of society who lived in space and who had no means of coming back to earth. Jean Tinguely saw me in space and signaled to me in speed to show me the last machine to take to return to the ephemerality of material life.
Yves Klein
No mockery in this world ever sounds to me so hollow as that of being told to cultivate happiness. What does such advice mean? Happiness is not a potato, to be planted in mould, and tilled with manure. Happiness is a glory shining far down upon us out of Heaven. She is a divine dew which the soul, on certain of its summer mornings, feels dropping upon it from the amaranth bloom and golden fruitage of Paradise.
Charlotte Brontë
Now, since the time of Newton there had been a debate about whether light was a wave---that is, a traveling disturbance in some background medium---or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.

We catched fish, and talked, and we took a swim now and then to keep off sleepiness. It was kind of solemn, drifting down the big still river, laying on our backs looking up at the stars, and we didn't ever feel like talking loud, and it warn't often that we laughed, only a kind of low chuckle. We had mighty good weather, as a general thing, and nothing ever happened to us at all, that night, nor the next, nor the next.
Mark Twain
On some positions, cowardice asks the question, is it expedient? And then expedience comes along and asks the question, is it politic? Vanity asks the question, is it popular? Conscience asks the question, is it right? There comes a time when one must take the position that is neither safe nor politic nor popular, but he must do it because conscience tells him it is right.
