Intelligence is the ability to take in information from the world and to find patterns in that information that allow you to organize your perceptions and understand the external world.

The bottom line is that time travel is allowed by the laws of physics.

My mom says: 'Why aren't you a doctor?' and I'm like, 'I am a doctor!' and she's all, 'No, I mean a real doctor.' She reads my books, but she says they give her a headache.

In the far, far future, essentially all matter will have returned to energy. But because of the enormous expansion of space, this energy will be spread so thinly that it will hardly ever convert back to even the lightest particles of matter. Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.

Relativity challenges your basic intuitions that you've built up from everyday experience. It says your experience of time is not what you think it is, that time is malleable. Your experience of space is not what you think it is; it can stretch and shrink.

Every moment is as real as every other. Every 'now,' when you say, 'This is the real moment,' is as real as every other 'now' - and therefore all the moments are just out there. Just as every location in space is out there, I think every moment in time is out there, too.

When you buy a jacket, you pick the size to ensure it fits. Similarly, we live in a universe in which the amount of dark energy fits our biological make-up. If the amount of dark energy were substantially different from what we've measured, the environmental conditions would be inhospitable to our form of life.

Nature's patterns sometimes reflect two intertwined features: fundamental physical laws and environmental influences. It's nature's version of nature versus nurture.

My dad was a composer and a musician, but he never finished high school. His formal education was rather minimal from the standards of today's college graduates and Ph.D.'s, but he had a deep interest in questions of science and questions of the universe.

I drive around on my scooter in Milan alone - we don't have bodyguards or anything like that. I am a fashion designer, not a celebrity, and although I get stopped for autographs and the like, I don't think I am famous.

To me, flowers are happiness.

Dreams can still come true; you need a great deal of energy and determination, and a little bit of luck.

Fashion takes its inspiration from society and everyday life, which is the same for everyone, and this is perhaps the reason why certain elements recur.

We don't think only men can be powerful and strong. Behind the heads of the Mafia, the leaders of culture, there are always very strong women. European culture is a matriarchy, especially in the south. The women have a lot of power.

My motto is: feel the fear and do it anyway.

It's important for women to work. They need to keep their independence, to keep earning and being challenged.

My daughter is my passion and my life.

A live concert to me is exciting because of all the electricity that is generated in the crowd and on stage. It's my favorite part of the business, live concerts.

Until we meet again, may God bless you as he has blessed me.

Whatever I will become will be what God has chosen for me.

Truth is like the sun. You can shut it out for a time, but it ain't goin' away.

When I get married, it'll be no secret.

Rock and roll music, if you like it, if you feel it, you can't help but move to it. That's what happens to me. I can't help it.'

I don't know anything about music. In my line you don't have to.

It's human nature to gripe, but I'm going ahead and doing the best I can.

The army teaches boys to think like men.

I sure lost my musical direction in Hollywood. My songs were the same conveyer belt mass production, just like most of my movies were.

The next thing I knew, I was out of the service and making movies again. My first picture was called, GI Blues. I thought I was still in the army.

Later on they send me to Hollywood. To make movies. It was all new to me. I was only 21 years old.

Those movies sure got me into a rut.

Too much TV hurts movies.

I hope I didn't bore you too much with my life story.

Just because I managed to do a little something, I don't want anyone back home to think I got the big head.

More than anything else, I want the folks back at home to think right of me.

Being a famous actress may give you a sense of being important, but believe me, it's just an illusion.

It's never been my purpose to become an American icon, or more famous or richer.

What I love most about this crazy life is the adventure of it.

For me, habit is just a synonym for death.

I've never thought of my characters as being sad. On the contrary, they are full of life. They didn't choose tragedy. Tragedy chose them.

For me, acting goes to a special place; it's almost mystical. You have to let go of what you think is good; it's a jump into trust, and trying to reach without wanting too much.

My ambition is to have beautiful encounters, not to make money.

I was used to theatre classes. I studied with my mother; she was a theatre teacher and directed, too, so it was very family-like. Then I studied with a great teacher in Paris, and she was wonderful; she pushed me, but she was a warm soul.

It's not a struggle to be on a diet. You feel lighter, and your spirit is lighter, too. But I love chocolate, and I allow myself to have chocolate. That doesn't go against a diet for me.

Life is filled with tragedy, with long patches of struggle and with, I think, beautiful bursts of joy and accomplishment. Blessed with those moments, you just try to relax as much as possible and focus on the little things, like the joy of changing your baby's diaper.

What about the rat race in the first place? Is it worthwhile? Or are you just buying into someone else's definition of success? Only you can decide that, and you'll have to decide it over and over and over. But if you think it's a rat race, before you drop out, take a deep breath. Maybe you picked the wrong job. Try again. And then try again.

I'm not pretending I can give advice to every single person or every single couple for every situation; I'm making the point that we are not going to get to equality in the workforce before we get to equality in the home. Not going to happen.

It is the ultimate luxury to combine passion and contribution. It's also a very clear path to happiness.

It turns out that a husband who does the laundry, it's very romantic when you're older. And it's hard to believe when you're younger. But it's absolutely true.

Writing about joyful experiences for just three days can improve people's moods and decrease their visits to health centers a full three months later.

Our discomfort with female leadership runs deep. We call little girls bossy. We never really call little boys bossy, because a boy is expected to lead, so it doesn't surprise or offend.
