The basic thing nobody asks is why do people take drugs of any sort? Why do we have these accessories to normal living to live? I mean is there something wrong with society that's making us so pressurized that we cannot live without guarding ourselves against it?

The finest clothing made is a person's own skin but of course society demands something more than this.

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.

I just smile. And they - my opponents don't like it when I smile at them. They think I'm playing or something. But - like I smile throughout the whole fight. Sometimes I'll be throwing combinations and I just smile and stick my tongue out at them.

I wake up each and every day with a smile on my face knowing I get to do something musically.

While you're improvising you may come up with something which will break him up. As soon as that smile comes out you know that hey we're having fun.

When you see that many people with a smile on their face then you must be doing something right.

I feel like a little kid who just walked into a candy store. I think that's something to smile about.

The coolest part about seeing a girl wear something comfortable is the smile that you can just feel coming through from inside her.

The problem with allowing God a role in the history of life is not that science would cease but rather that scientists would have to acknowledge the existence of something important which is outside the boundaries of natural science.

If you publish a scientific paper it is very hard to start a nationwide debate about something. If you do this in a movie you can start a debate. We like to create a bridge between those two worlds - film and science.

I believe that science fiction is as profound as you want it to be or it can be very simple entertainment and I'm all for very simple entertainment. Every now and then we all need to come home veg-out watch something and not think too deeply about it. It's what you want it to be. We tend to steer clear of being pedantic it's entertainment first otherwise we'd be on a lecture circuit.

I'd always wanted the show to be more reality based science fiction something along the lines of The Day the Earth Stood Still which I consider to be the classic science fiction film.

However I wasn't very good at the sciences or didn't have a lot of help in the sciences or something but certainly didn't set science for my A level. And when I came to take my A levels I didn't get a good enough result to go to University.

Science is not about control. It is about cultivating a perpetual condition of wonder in the face of something that forever grows one step richer and subtler than our latest theory about it. It is about reverence not mastery.

Science is defined in various ways but today it is generally restricted to something which is experimental which is repeatable which can be predicted and which is falsifiable.

One of the problems we've had is that the ICT curriculum in the past has been written for a subject that is changing all the time. I think that what we should have is computer science in the future - and how it fits in to the curriculum is something we need to be talking to scientists to experts in coding and to young people about.
