A Quote by Margaret Wertheim

One way to think about a pure hyperbolic surface is that it's the geometric opposite of a sphere. If you look at a sphere, the curvature is the same everywhere, as opposed to, say, an egg, which clearly does not curve the same everywhere. This is what makes spheres geometrically important. Mathematically speaking, a sphere has positive curvature and a hyperbolic surface has negative curvature, but both have constant curvature everywhere.

You encountered a misery near the end of the day and it took a while to gauge its full extent. Some miseries had sharp curvature and could be negotiated readily. Others had almost no curvature and you knew you'd be spending hours turning the corner. Great whopping-big planet-sized miseries.

Jonathan Franzen

It's a brilliant surface in that sunlight. The horizon seems quite close to you because the curvature is so much more pronounced than here on earth. It's an interesting place to be. I recommend it.

Neil Armstrong

Sometimes, properties of a fixed hyperbolic surface can be better understood by studying the moduli space that parameterises all hyperbolic structures on a given topological surface.

Maryam Mirzakhani

God is an intelligible sphere-a sphere known to mind, not to the senses-whose center is everywhere and whose circumference nowhere.

Joseph Campbell

All motion is curved and all curvature is spiral.

Walter Russell

We often say that the earth is a sphere, but to be precise, the term sphere refers only to the surface. The correct mathematical term for the solid earth is a ball.

Leonard Susskind

The course is so long, I had to take the curvature of the Earth into consideration.

David Feherty

Nature is an infinite sphere of which the center is everywhere and the circumference nowhere.

Blaise Pascal

I say people who feel they must have a faith or religion in order to face life are showing a kind of cowardice, which in any other sphere would be considered contemptible. But when it is in the religious sphere it is thought admirable, and I cannot admire cowardice whatever sphere it is in.

Bertrand Russell

There is no such thing as a sphere for sex. Every man has a different sphere, in which he may or may not shine, and it is the same with every woman, and the same woman may have a different sphere at different times.

Elizabeth Cady Stanton

Indeed, linear extrapolations make no large-scale sense in a universe that has spatial and temporal curvature.

Peter J. Carroll

If today there is a proper American "sphere of influence" it is this fragile sphere called earth upon which all men live and share a common fate--a sphere where our influence must be for peace and justice.

Hubert H. Humphrey

There's no proof of the Earth's curvature and this fake space agency Nasa use CGI images and every one is different.

Carl Froch

I was lucky enough to fly in Concorde, and you get up to 65,000 feet, and I could see the curvature of the Earth.

Phillip Schofield

We continually forget that the sphere of morals is the sphere of action, that speculation in regard to morality is but observation and must remain in the sphere of intellectual comment, that a situation does not really become moral until we are confronted with the question of what shall be done in a concrete case, and are obliged to act upon our theory.
