Gavin Pretor-Pinney is a giggler inveterate, with the smooth, rubicund features of a British banker and a crushed lisp, exuberant in his passions and determined to heal the damage wreaked by geography masters the world over.
'It's amazing how in the wrong hands, a subject can be mangled,' he says from a farmhouse near Beziers in southern France, where he is on holiday with his wife, Liz, and their two daughters, Flora Cirrus and Verity Iris. His first book, The Cloudspotter's Guide, sold more than 250,000 copies in 17 translations and is now regarded as the bible of a new religion. His second, The Wave Watcher's Companion, released in June, is up for the same destiny.
