Winding or circling round a center or pole and gradually receding from it; as, the spiral curve of a watch spring.
Winding round a cylinder or imaginary axis, and at the same time rising or advancing forward; winding like the thread of a screw; helical.
Of or pertaining to a spiral; like a spiral.
A plane curve, not reentrant, described by a point, called the generatrix, moving along a straight line according to a mathematical law, while the line is revolving about a fixed point called the pole. Cf. Helix.
Anything which has a spiral form, as a spiral shell.
Looking up and out, how can we not respect this ever-vigilant cognizance that distinguishes us: the capability to envision, to dream, and to invent? the ability to ponder ourselves? and be aware of our existence on the outer arm of a spiral galaxy in an immeasurable ocean of stars? Cognizance is our crest. Vanna Bonta
Fear stifles our thinking and actions. It creates indecisiveness that results in stagnation. I have known talented people who procrastinate indefinitely rather than risk failure. Lost opportunities cause erosion of confidence, and the downward spiral begins. Charles Stanley
A circle is the reflection of eternity. It has no beginning and it has no end - and if you put several circles over each other, then you get a spiral. Maynard James Keenan
The spiral in a snail's shell is the same mathematically as the spiral in the Milky Way galaxy, and it's also the same mathematically as the spirals in our DNA. It's the same ratio that you'll find in very basic music that transcends cultures all over the world. Joseph Gordon-Levitt
Modern man must descend the spiral of his own absurdity to the lowest point; only then can he look beyond it. It is obviously impossible to get around it, jump over it, or simply avoid it. Vaclav Havel
