Work is of two kinds: first, altering the position of matter at or near the earth's surface relative to other matter; second, telling other people to do so.

The subject matter of the stories on the surface... there seem to be a number of stories about travel.

The only technology that can 'see' beneath the ground is radar imagery. But satellite imagery also allows scientists to map short- and long-term changes to the Earth's surface. Buried archaeological remains affect the overlying vegetation, soils and even water in different ways, depending on the landscapes you're examining.

It's not very interesting to establish sympathy for people who, on the surface, are instantly sympathetic. I guess I'm always attracted to people who, if their lives were headlines in a newspaper, you might not be very sympathetic about them.

Confession of errors is like a broom which sweeps away the dirt and leaves the surface brighter and clearer. I feel stronger for confession.

I've got a beautiful kitchen, which looks like a '60s version of space, with silver chrome, orange glass work surfaces, and brown leather, and it's entirely visual and has little function. I've hardly got any knives, and there's only one wooden spoon and one saucepan. But I think I've got a cheese grater, so that's good.

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.

We want to make sure we get living astronauts to the surface of Mars.

There is good evidence that Venus once had liquid water and a much thinner atmosphere, similar to Earth billions of years ago. But today the surface of Venus is dry as a bone, hot enough to melt lead, there are clouds of sulfuric acid that reach a hundred miles high and the air is so thick it's like being 900 meters deep in the ocean.

There is no society ever discovered in the remotest corner of the world that has not had something that we would consider the arts. Visual arts - decoration of surfaces and bodies - appears to be a human universal.

Generally speaking, talk to any stand-up comedian, the people in this world who are the brightest and have the biggest smile often are struggling with a lot of things under the surface.

In science there are no 'depths'; there is surface everywhere.

When my dad passed, there's a lot of sadness right below the surface, and I think there will be until the day I die. So, writing sad songs helps it. And when I sing them, it's pure therapy for me.

I finally did work out a very good relationship with my father, but it was rough growing up. We had a lot of conflict, and I think it surfaced in many of my works.

I don't think you get to good writing unless you expose yourself and your feelings. Deep songs don't come from the surface; they come from the deep down. The poetry and the songs that you are suppose to write, I believe are in your heart.

It may be said that poems are in one way like icebergs: only about a third of their bulk appears above the surface of the page.

Bats drink on the wing, like swallows, by sipping the surface, as they play over pools and streams.

If the whole of mankind is to be united into one brotherhood, all obstacles must be removed so that men, all over the surface of the globe, should be as children playing in a garden.

God grant that not only the love of liberty but a thorough knowledge of the rights of man may pervade all the nations of the earth, so that a philosopher may set his foot anywhere on its surface and say: 'This is my country.'

The essence of religion is the knowledge of God which is eternal life. That and nothing less than that is religion. Everything else is on the surface, is superfluous save for the needs of men.

The fact that television and tourism have made the whole world accessible has created the illusion that we enjoy intimate knowledge of other places, when we barely scratch their surface. For the vast majority, the knowledge of Thailand or Sri Lanka acquired through tourism consists of little more than the whereabouts of the beach.

When people rely on surface appearances and false racial stereotypes, rather than in-depth knowledge of others at the level of the heart, mind and spirit, their ability to assess and understand people accurately is compromised.

It becomes a giant's task to compute the result when the effect of cross seas, wind at all angles and ever varying force, arched surfaces, head resistance, ratio of weight to area, and the intelligence of the guiding power crop up.

Having read the histories of other countries, I saw that expansion was everything, and that the world's surface being limited, the great object of present humanity should be to take as much of the world as it possibly could.
