I was a terrible science student, and for a long time, I thought I just didn't understand science. It turned out that I didn't understand post-Newtonian science. I could actually understand how people thought scientifically about the world in the past.

I teach 18- to 21-year-olds - the 'Harry Potter' generation. They grew up as voracious readers, reading books in this exploding genre. But at some point, I would love for them to give Umberto Eco or A.S. Byatt a try. I hope 'A Discovery of Witches' will serve as a kind of stepping-stone.

I couldn't resist hiding some historical details and a few clues relevant to the plot and characters of 'A Discovery of Witches' throughout the pages of the novel.

I found a 'lost' manuscript called the Book of Soyga that had once belonged to Queen Elizabeth I's court astrologer, John Dee, in Oxford's Bodleian Library. Everybody thought it was the missing key to Dee's interest in magic. Of course, it wasn't really lost. It was there, in the catalog.

I've always had bronchitis. I've been administered the Sacrament of Death three times for it.

I work with the options I have in front of me and my reasons for choosing a job can vary enormously depending on the circumstances. Sometimes I take a job because it's a group of people I'm dying to work with, and sometimes it can be a desire to shake things up a bit and not to take myself too seriously.

I'm not going to be here forever. I don't plan on going anywhere, but I don't know anybody for whom death is an exception.

There are a lot of downsides to being male. We age faster and die younger. But give us this: we're lifetime baby-making machines. Women's reproductive abilities start to wane when they're as young as 35. Men? We're good to go pretty much till we're dead.
