We may have a tacit understanding of how our solar system works, but watching the sun disappear behind the moon reminds us of the vastness of space and the enduring mysteries of the universe we inhabit.

The rhythm of relations of color and size makes the absolute appear in the relativity of time and space.

The stars look the same from night to night. Nebulae and galaxies are dully immutable, maintaining the same overall appearance for thousands or millions of years. Indeed, only the sun, moon and planets - together with the occasional comet, asteroid or meteor - seem dynamic.

According to String Theory, what appears to be empty space is actually a tumultuous ocean of strings vibrating at the precise frequencies that create the 4 dimensions you and I call height, width, depth and time.

Women have face-lifts in a society in which women without them appear to vanish from sight.

So much of the language that surrounds us - from things like economics, management theory, and the algorithms built into computer systems - appears to be objective and neutral. But in fact, it is loaded with powerful, and very debatable, political assumptions about how society should work and what human beings are really like.

Having soon discovered to be great, I must appear so, and therefore studiously avoided mixing in society, and wrapped myself in mystery, devoting my time to fasting and prayer.

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.

The world is governed more by appearance than realities so that it is fully as necessary to seem to know something as to know it.

Since my dimples only appear whenever I smile, facing everything in life with that smile is a wonderful feeling. Eyes are also the window to one's self. Just a look can reflect your identity and experiences.

No connection to the average voter - Clinton has an air of superiority. Despite her wide smile and pleasant appearance, she is envisioned as someone who is trying to hide something all the time.

If you can't relax during your interview, then nothing you do to prepare will matter. Being yourself is essential to the selection process, and interviewers will feel it if you're too nervous. Showing fear or anxiety appears weak compared to a relaxed smile and genuine confidence.

Scarlett Johansson has a smile she tries to suppress in every movie she makes. She's been trying to keep a straight face since she appeared with Bill Murray 11 years ago in her breakthrough, 'Lost in Translation.'

Someone asked me the other day what it feels like to see all my 'old stuff' reappearing, at long last, in digital. And I had to smile because to me it doesn't feel like 'old stuff.'

I suffered from post-natal depression after Rowan was born. I had a healthy, beautiful baby girl and I couldn't look at her. I couldn't hold her, smile at her. All I wanted was to disappear and die.

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.

The Connecticut Center for Science and Exploration will be a building that will connect the excitement of science to the surrounding streets, river and highway. These forms are ambitious and dynamic. They appear to reach out beyond their physical limits.

In order for the United States to do the right things for the long term, it appears to be helpful for us to have the prospect of humiliation. Sputnik helped us fund good science - really good science: the semiconductor came out of it.

If anyone offers conjectures about the truth of things from the mere possibility of hypotheses, I do not see by what stipulation anything certain can be determined in any science, since one or another set of hypotheses may always be devised which will appear to supply new difficulties.

Fashion is the science of appearance, and it inspires one with the desire to seem rather than to be.

The work of science is to substitute facts for appearances, and demonstrations for impressions.

For an object under the eye will appear very different from the same object placed above it; in an inclosed space, very different from the same in an open space.

When DVDs finally disappear, I'm going to be sad. I'll miss the commentaries.

I'm a person who likes these sort of movies... sad but moving 'art movies' that normally are at a festival and then they go to a small art house theater and disappear.
