Let's begin with a confession: I read New Scientist (whispers). All right, I'll say it out loud: I read New Scientist. At first, I bought it for my kids, on the advice of a kindly high school Physics teacher, unwrapped it each week and gave them first option, only retrieving it if, after five days, it remained untouched and in pristine condition. I moved rapidly on to leaving it on the kitchen table overnight, awaiting takers. But within a few weeks, I had moved to waiting by the door for its delivery, devouring the articles which interested me and leaving it crumpled in a heap by my bedside.
