As Joanna Lumley notes in her preface, Bruce Denness has always trod a precarious path between serious science and philosophical frivolity. The science reached its peak at the British Geological Survey and Newcastle University in the 1970s but even then - and certainly since - he always looked for the funny side of whatever he was involved in, which may explain why his research has seldom been taken seriously. Bruce was born in 1942 on a farm in the Isle of Wight, where he grew up. His career then took him to the mainland (or England, as it is known on the Isle of Wight) and several countries in the Caribbean, South America and the Far East before he settled back on the Island again in 1984. Experiences gained during those years have contributed to the many letters that Bruce has since had published, mainly in The Telegraph and New Scientist. Admittedly, some of them may also have been influenced by regular visits to The White Horse Inn at Whitwell, Isle of Wight for invigorating Shiraz treatment.
