I think the biggest innovations of the twenty-first century will be the intersection of biology and technology. A new era is beginning, just like the digital one was when I was his age.

Leonardo da Vinci had such a playful curiosity. If you read his notebooks, you'll see he's curious about what the tongue of a woodpecker looks like, but also why the sky is blue, or how an emotion forms on somebody's lips. He understood the beauty of everything. I've admired Leonardo my whole life, both as a kid who loved engineering - he was one of the coolest engineers in history - and then as a college student, when I travelled to see his notebooks and paintings.

Leonardo da Vinci did not take received wisdom - whether from ancient classical thinkers or medieval scholars or from the Bible - without questioning it. And this was the beginning of the scientific method. This is another lesson for our time: that when we have evidence that contradicts a certain belief, we should be willing to change it. I think this made Leonardo, in some ways, a person who better understood the beauty of God's creation than a person who just takes all received wisdom from the Bible on faith.

I've asked Jobs why he didn't get an operation then and he said, 'I didn't want my body to be opened... I didn't want to be violated in that way.'

Physics should represent a reality in time and space, free from spooky action at a distance.
