I shall now recall to mind that the motion of the heavenly bodies is circular, since the motion appropriate to a sphere is rotation in a circle.
— Nicolaus Copernicus
Vibrant Circular Motion quotations
If... the motion of the earth were circular, it would be violent and contrary to nature, and could not be eternal, since ... nothing violent is eternal .... It follows, therefore, that the earth is not moved with a circular motion.
While most of those who hold that the whole heaven is finite say that the earth lies at the center, the philosophers of Italy, the so-called Pythagoreans, assert the contrary. They say that in the middle there is fire, and that the earth is one of the stars, and by its circular motion round the center produces night and day.
I see the experience of pictures as a kind of cycle, a kind of circular motion in which you're in the world, then you enter the picture and you're in a different world (it's not the same as the one you live in, but recognizable as one you might live in). And then you're returned to your world with an enlarged sense of its possibilities.
I made a circular motion with my finger around my temple to indicate I thought this guy was crazy, forgetting that there was no one in the room to see this circular motion except him. He saw it and frowned.
Men go abroad to wonder at the heights of mountains, at the huge waves of the sea, at the long courses of the rivers, at the vast compass of the ocean, at the circular motions of the stars, and they pass by themselves without wondering.
People travel to wonder at the height of the mountains, at the huge waves of the seas, at the long course of the rivers, at the vast compass of the ocean, at the circular motion of the stars, and yet they pass by themselves without wondering.
I proceeded to take that mitten full of the deadly yellow snow crystals and rub it all into his beady little eyes with a vigorous circular motion.
We see only the simple motion of descent, since that other circular one common to the Earth, the tower, and ourselves remains imperceptible. There remains perceptible to us only that of the stone, which is not shared by us; and, because of this, sense shows it as by a straight line, always parallel to the tower, which is built upright and perpendicular upon the terrestrial surface.
