“The world and the universe is an extremely beautiful place, and the more we understand about it the more beautiful does it appear. It is an immensely exciting experience to be born in the world, born in the universe, and look around you and realise that before you die you have the opportunity of understanding an immense amount about that world and about that universe and about life and about why we're here. We have the opportunity of understanding far, far more than any of our predecessors ever. That is such an exciting possibility, it would be such a shame to blow it and end your life not having understood what there is to understand.”
