In my heart, I'm just a kid from the council houses. I can remember the old cottage and my dad coming round with the tin bath. I'm not a rich man.

I think when people mean that Discworld books have become darker they really mean the series is growing up. In 'The Colour of Magic' most of the city is set alight. It's a joke, in much the same way that the Earth is destroyed almost at the start of Douglas Adams's 'The Hitchhikers Guide to the Galaxy.'

I grow as many of our vegetables as I can, because my granddad was a professional gardener, and it's in the blood.

Science is a principle and a process of seeking truth. Truth cannot be purchased, and thus, truth cannot be altered by money.

I want e by Jose Andres to be a discovery, to be a journey. I want people to find it and be astonished.

In a world where discovery is more important than delivery, it's the people who find, remix and direct attention to old stuff that should be rewarded, not the people who deliver it or sit on it waiting for someone to show up.
