When a nation goes down or a society perishes one condition may always be found they forgot where they came from. They lost sight of what had brought them along.

A society made up of individuals who were all capable of original thought would probably be unendurable.

Perhaps in time the so-called Dark Ages will be thought of as including our own.

We ought to be beating our chests every day. We ought to look in the mirror stick out our chests suck in our bellies and say 'Damn we're Americans ' and smile.

The man who can smile when things go wrong has thought of someone else he can blame it on.

The virtues of science are skepticism and independence of thought.

As a kid I wanted to write science fiction and I was never without a book. Later I really got into being a scientist and never thought I'd be writing novels.

And I thought I would just share with you what science says today about silicone breast implants. If you have them you're healthier than if you don't. In fact there's no science that shows that silicone breast implants are detrimental and in fact they make you healthier.

Science already contained all that was necessary if you just brought it out.

I would be more frightened as a writer if people thought my movies were like science fiction.

He that desireth to acquire any art or science seeketh first those means by which that art or science is obtained. If we ought to do so in things natural and earthly how much more then in spiritual?

You know there was a time just before I started to study physical science when astronomers thought that systems such as we have here in the solar system required a rare triple collision of stars.

As a theoretical physicist I feel at once proud and humble at the thought of the illustrious figures that have preceded me here to receive the greatest of all honors in science the Nobel prize.

I told my father I had to try political science for a year. He thought I was throwing my life away.

I've started a company called Tall Girl Productions and we've got our first project that is purely producing not writing with a writer named Evan Daugherty. It's for NBC it's called 'Afterthought ' and it's science fiction-ish. That's fun.

I wanted to have a political career. I thought studying political science would be the best way to achieve it.

One of the nice things about science fiction is that it lets us carry out thought experiments.

Science will explain how but not why. It talks about what is not what ought to be. Science is descriptive not prescriptive it can tell us about causes but it cannot tell us about purposes. Indeed science disavows purposes.

Though many have tried no one has ever yet explained away the decisive fact that science which can do so much cannot decide what it ought to do.

Time travel used to be thought of as just science fiction but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.

Mainly I thought of Barney as a kid. You can always look into the faces of kids and see what they're thinking if they're happy or sad. That's what I tried to do with Barney.

I must have something to engross my thoughts some object in life which will fill this vacuum and prevent this sad wearing away of the heart.

I love the script and I just thought it was a great role. Like I say it's like this - the script is like this sad funny desperate love song to the lost American man.

I found out about reviews early on. They're mostly written by sad men on bad afternoons. That's probably why I'm less angry than some writers who are so narcissistic they consider every line of every review even a thoughtful one as major treason.
