“A circle is a round straight line with a hole in the middle.”
"Geometry is just plane fun."
"The only angle from which to approach a problem is the TRY-Angle"
"The shortest distance between two points is under construction." -- Bill Sanderson
"Geometry is the science of correct reasoning on incorrect figures." - George Polya
"Without geometry life is pointless."
“I heard that parallel lines actually do meet, but they are very discrete.”
"Geometry is the foundation of all painting." -- Albrecht Durer
"My geometry teacher was sometimes acute, and sometimes obtuse, but always, he was right. "
"I am persuaded that this method [for calculating the volume of a sphere] will be of no little service to mathematics. For I foresee that once it is understood and established, it will be used to discover other theorems which have not yet occurred to me, by other mathematicians, now living or yet unborn." -- Archimedes
Expression and shape are almost more to me than knowledge itself. My work has always tried to unite the true with the beautiful, and when I have had to choose one or the other, I usually chose the beautiful -- H. Weyl
"Everything tries to be round." -- Black Elk
[A mathematician is a] scientist who can figure out anything except such simple things as squaring the circle and trisecting an angle. -- Evan Esar, Esar's Comic Dictionary
"Where there is matter, there is geometry." -- Johannes Kepler
"We cannot ... prove geometrical truths by arithmetic." -- Aristotle
"Mighty is geometry; joined with art, resistless." -- Euripides
"I am ever more convinced that the necessity of our geometry cannot be proved -- at least not by human reason for human reason." -- Carl Friedrich Gauss
"Geometry is one and eternal shining in the mind of God. That share in it accorded to men is one of the reasons that Man is the image of God." -- Johannes Kepler
"As long as algebra and geometry have been separated, their progress have been slow and their uses limited; but when these two sciences have been united, they have lent each mutual forces, and have marched together towards perfection." -- Joseph Louis Lagrange
"It is the glory of geometry that from so few principles, fetched from without, it is able to accomplish so much." -- Sir Isaac Newton
"The description of right lines and circles, upon which geometry is founded, belongs to mechanics. Geometry does not teach us to draw these lines, but requires them to be drawn." -- Sir Isaac Newton
"Let no one ignorant of geometry enter here." -- Plato
"The knowledge of which geometry aims is the knowledge of the eternal." -- Plato
“A circle has no end.” -- Isaac Asimov
"One geometry cannot be more true than another; it can only be more convenient."-- Henri Poincare
A youth who had begun to read geometry with Euclid, when he had learnt the first proposition, inquired, "What do I get by learning these things?" So Euclid called a slave and said "Give him threepence, since he must make a gain out of what he learns. -- Euclid of Alexandria
"Once upon a time there was a sensible straight line who was hopelessly in love with a dot. 'You're the beginning and the end, the hub, the core and the quintessence,' he told her tenderly, but the frivolous dot wasn't a bit interested, for she only had eyes for a wild and unkempt squiggle who never seemed to have anything on his mind at all. All of the line's romantic dreams were in vain, until he discovered . . . angles! Now, with newfound self-expression, he can be anything he wants to be--a square, a triangle, a parallelogram. . . . And that's just the beginning!" -- Juster Norton
Geometry is a skill of the eyes and the hands as well as of the mind. -- Pedersen, Jean.
Mankind is not a circle with a single center but an ellipse with two focal points of which facts are one and ideas the other. -- Victor Hugo
