If I could do anything in my life and be remembered for anything, I would like to be remembered for helping the world see the value of physical engagement with ideas.

This is what I call the "cosmological problem" of science. Science has the instrumental function that has given us computers and so on, but its cosmological function is to give us a picture of the world we inhabit as human beings, and on that level it's failing a vast number of people.

All gradients of reality, all existential distinctions, have finally been annihilated.

Simple DNA gradually morphed and evolved, so that you had the coming into being of ever more complex and diverse creatures, until one day you wake up and find there are peacocks and giraffes. Nature is an open-ended experiment based on morphing a DNA code, and ours is an open-ended experiment based on morphing a crochet code.

Seeing and playing with physical objects can enable access to symbolic ideas. When I studied physics and math at university it was all done through equations and textbooks whereas artists go to art school and start making stuff; they fling paint at the walls, they dance and bash things together with giant bits of metal. Our society has come to think of science as being a very abstractified thing, and art as being a materialized thing.

Almost all major scientific projects today are huge collaborations, yet we still have this public obsession with the idea of the individual scientific genius. One of my goals as a science communicator is to celebrate the collaborative dimensions of science, which I think will be critical for facing the ecological and resource challenges ahead. In a sense, we are all corals now.
