“It seems to be a law of design that for every advantage introduced through redesign, there is an accompanying unintended disadvantage.”
Henry Petroski“As engineers, we were going to be in a position to change the world - not just study it.”
Henry Petroski“Too much redesign has to do more with fad and fashion than with fitness and function. It is change for the sake of change. Such redesign is not only unnecessary, it is all too often also retrogressive, leading to things that work less effectively than those they were designed to replace.”
Henry Petroski“Failures are much more dramatic than successes, and people like drama. I think this is why automobile races draw such crowds. People expect spectacular crashes, which we tend to find more interesting than cars just racing around the track. The same is true of bridges, buildings, or any structure or machine.”
Henry Petroski“It seems to be a law of design that for every advantage introduced through redesign, there is an accompanying unintended disadvantage.”
Henry Petroski“We call the fates of the Titanic and the Concordia - as well as those of the space shuttles Challenger and Columbia - 'accidents.' Foreseeing such undesirable events is what engineers are expected to do. However, design trade-offs leave technological systems open to failings once predicted, but later forgotten.”
Henry Petroski“I have always been fascinated by the way things work and how they came to take the form that they did. Writing about these things satisfies my curiosity about the made world while at the same time giving me an opportunity to design a new explanation for the processes that shape it.”
Henry Petroski“Because every design must satisfy competing objectives, there necessarily has to be compromise among, if not the complete exclusion of, some of those objectives, in order to meet what are considered the more important of them.”
Henry Petroski“All conventional wisdom has an element of truth to it, but good design requires more than an element of truth - it requires an ensemble of correct assumptions and valid calculations.”
Henry Petroski“No design, no matter how common or seemingly insignificant, is without its adamant critics as well as its ardent admirers.”
