I was interested in it. Science fascinates me and I've taken New Scientist for years. All of my books are preoccupied with time - it starts right back in Oranges in the Deuteronomy section. In Sexing the Cherry I use time vertically, not just horizontally, and in Gut Symmetries I wanted to explore the dimensionality of time. These are questions the book deals with, not because I hope to answer them, but as a way of adding to the puzzle.
Triangles are so much more fascinating than straight lines.
It's a geometry thing. The human heart is my territory. Gut Symmetries is about all kinds of relationships - between parents and children, children and grandparents, husbands and wives, friends, as well as sexual affairs whether heterosexual or queer. I write about love because it's the most important thing in the world. I write about sex because often it feels like the most important thing in the world.
