Query: For Petroski Fans Only

This is a collection of articles written for Petrowski's monthly column in American Scientist magazine. Many are brief biographies of 19th-century engineers; a (very) few look (very) briefly at particular pieces of historical engineering (an article on the Ferris wheel is probably the best); others are ruminations on such hazards of the engineering practice as the stress that keeps them up at night and their failure to be awarded Nobel prizes. These seem quite satisfactory articles for a magazine column but they are slender stuff for a book. And Petroski's tendency to return to the same subjects, pardonable in a monthly column, becomes repetitive when the columns are collected. All but die-hard Petroski fans can skip this one
