Book Review: Remaking the World (Petroski)

Petroski, Henry Remaking the World (1999) Jon gave me this book for Christmas. Petroski wrote historical essays for American Scientist, a magazine that appears to carry on the original intent of Scientific American, which was much more focussed on technology (and even DIY) than the current version. His essays are very much like Gould’s, but the style is somewhat more neutral and pedestrian. I get little sense of Petroski’s personality, which is a pity, since his choice of subjects indicates a lively mind and wide range of interest.

His emphasis on the non-technical aspects of engineering is important. Most people lack scientific and technical insight (we need a word like “illiteracy” for this), which means that the context of engineering works is often incomplete. The yearning for quick fixes prompts politicians and their constituents to trust the technocrats too much (see the “heightening” of “security measures” at airports recently). On the other hand, nimbyism and paranoid Ludditism result in know-nothing rejection of economically viable and ecologically effective solutions (see the resistance to H1N1 vaccination.)

All in all, a good book, with useful nuggets of information here and there. For example, “bug” as a glitch or unexpected flaw in design predates computers. Petroski quotes a note in Edison’s diary, in which Edison refers to “Bugs – as such little faults and difficulties are called –”. I’ve suspected that the “insect in the electronic works” was a story a little too pat to be true, and am happy to have my suspicion confirmed. ***
