# Circles

Circles are simple shapes of Euclidean geometry consisting of those points in a plane which are equidistant from a given point, the centre. They can be described as closed curves which divide the plane into two regions: an interior and an exterior. In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure, or to the whole figure including its interior; in strict technical usage, the circle is the former and the latter is called a disk.

Birds make their nest in circles, for theirs is the same religion as ours. The sun comes forth and goes down again in a circle. The moon does the same and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were.

* Never, never rest contented with any circle of ideas, but always be certain that a wider one is still possible.
** Richard Jefferies, Story of My Heart : My Autobiography (1901).
* Circularity is a powerful concept, the idea of a closed loop even more so. In circular motion there is magic, just as there is in electro-magnetism. But it only manifests itself when it is, like (shall we say for the moment, rather than a 'reflection' of) its 'neighboring head', truly three-dimensional. ...We can induce current into the one [coil] from the other by means totally unintelligible to us, but to which we give the name 'electromagnetic induction'. But if I place one coil with its axis at right-angles to that of the other, there is no induced voltage. It is as if the two circuits lived in different worlds... What is the meaning of perspective in a four-dimensional space?
** Eric Laithwaite, Engineer Through the Looking-Glass (1980) Ch. 4, The Jabberwock, pp. 41-42.

* There must be a positive and negative in everything in the universe in order to complete a circuit or circle, without which there would be no activity, no motion.

* And the seasons they go round and round, And the painted ponies go up and down, We're all captive on the carousel of time We can't return we can only look behind From where we came And go 'round and 'round and 'round In the circle game.
** Joni Mitchell, "The Circle Game," from Ladies of the Canyon (1970).
* No one ever squared the circle with so much genius, or, excepting his principal object, with so much success.
** Attributed to Jean-Étienne Montucla in Augustus De Morgan, A Budget of Paradoxes, (London, 1872): About Gregory St. Vincent, described by De Morgan as "the greatest of circle-squarers, and his investigations led him into many truths: he found the property of the arc of the hyperbola which led to Napier's logarithms being called hyperbolic."
* Mathematics would certainly have not come into existence if one had known from the beginning that there was in nature no exactly straight line, no actual circle, no absolute magnitude.

** Alexander Pope, Temple of Fame, line 436. Reported in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 119.

* The universe was made on purpose, the circle said. In whatever galaxy you happen to find yourself, you take the circumference of a circle, divide it by its diameter, measure closely enough, and uncover a miracle — another circle, drawn kilometers downstream of the decimal point. There would be richer messages farther in. It doesn't matter what you look like, or what you're made of, or where you come from. As long as you live in this universe, and have a modest talent for mathematics, sooner or later you'll find it. It's already here. It's inside everything. You don't have to leave your planet to find it. In the fabric of space and in the nature of matter, as in a great work of art, there is, written small, the artist’s signature. Standing over humans, gods, and demons, subsuming Caretakers and Tunnel builders, there is an intelligence that antedates the universe.
