Over Christmas they've been running a special season of University Challenge in which the mentors of the nation- writers, professors, broadcasters- get to show that outside their particular spheres of expertise they're as ignorant as the rest of us. It's oddly reassuring to find, for exampe, that Professor Susan Blackmore- the celebrity parapsychologist- doesn't know her McGonagall from her Burns and that not a single egghead in a box of eight can place Leonardo's Last Supper in Milan.
My ex-partner has a PhD in Astronomy, but works as a seismologist. She was always totally amazed when I would do something like fix the toilet or change a door nob. I always felt like she appreciated my very practical skills.
