BullsEye Any object projects a very different image on the retina when lit from two different angles or when presented either on the left or on the right of visual fixation. This variability poses a severe challenge to the neural circuits that construct the categories with which we recognize the world. When we need to identify … Read more
Writing—this ingenious art to paint words and speech for the eyes. GFORGES DE It RF BREUF (French poet, 1617-1661) When he paid a visit to Ambrose, then bishop of Milan, Augustine observed a phenomenon that he judged strange enough to be worth noting in his memoirs: When [Ambrose] read, his eyes scanned the page and … Read more
One may wonder why English sticks to such a complicated spelling system. Indeed, Italians do not meet with the same problems. Their spelling is transparent: every letter maps onto a single phoneme, with virtually no exceptions. As a result, it only takes a few months to learn to read. This gives Italians an enormous advantage: … Read more
The tale of reading begins when the retina receives photons reflected off the written page. But the retina is not a homogeneous sensor. Only its central part, called the fovea, is dense in high-resolution cells sensitive to incoming light, while the rest of the retina has a coarser resolution. The fovea, which occupies about 15 … Read more

He would climb up her trunk and swing from her branches and eat apples. And they would play hide-and-go-seek. And when … Read more
Pastor Roberts’s particular brand of nuttiness takes the form of what he calls Hell Houses. A Hell House is a place where children are brought, by their parents or their Christian schools, to be scared witless over what might happen to them after they die. Actors play out fearsome tableaux of particular ‘sins’ like abortion … Read more
On 19 November 2001 The New Yorker carried an interview by Nasra Hassan of another failed suicide bomber, a polite young Palestinian aged twenty-seven known as ‘S’. It is so poetically eloquent of the lure of paradise, as preached by moderate religious leaders and teachers, that I think it is worth giving at some length: … Read more
‘Irreducible complexity’ is not a new idea, but the phrase itself was invented by the creationist Michael Behe in 1996.62 He is credited (if credited is the word) with moving creationism into a new area of biology: biochemistry and cell biology, which he saw as perhaps a happier hunting ground for gaps than eyes or … Read more
