A Quote by 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.
It's those difficult times that inform the next wonderful time, and it's a series of trade-offs, of events, of wins and losses.
I've always believed happiness is overrated, you know? It’s those difficult times that inform the next wonderful time, and it’s a series of trade-offs, of events, of wins and losses.
I think of events like the Challenger and 9/11 - events that move us so much that we never quite get over them. So it's important to go back and relive those feelings in order to remember how important those events were to us.
But technology is the real skin of our species. Humanity, correctly seen in the context of the last five hundred years, is an extruder of technological material. We take in matter that has a low degree of organization; we put it through mental filters, and we extrude jewelry, gospels, space shuttles. This is what we do. We are like coral animals embedded in a technological reef of extruded psychic objects. All our tool making implies our belief in an ultimate tool. That tool is the flying saucer, or the soul, exteriorized in three-dimensional space.
Our nation is indeed fortunate that we can still draw on an immense reservoir of courage, character, and fortitude, that we are still blessed with heroes like those of the Space Shuttle Challenger. Man will continue his conquest of space. To reach out for new goals and ever-greater achievements, that is the way we shall commemorate our seven Challenger heroes.
In the judgment of design engineers, the ordinary means of communicating with a computer are entirely inadequate. [...] Graphical communication in some form or other is of vital importance in engineering as that subject is now conducted; we must either provide the capability in our computer systems, or take on the impossible task of training up a future race of engineers conditioned to think in a different way.
Don't bring on the design engineers too soon. One of the worst things you can do in the early phases of a project is to bring on a bunch of detailed design engineers and then not give them clear direction and close supervision.
A common misconception about how things such as space shuttles come to be is that engineers simply apply the theories and equations of science. But this cannot be done until the new thing-to-be is conceived in the engineer's mind's eye. Rather than following from science, engineered things lead it.
We believe that climate change must be viewed not only as a danger to natural systems, but also as a direct threat to human survival and well-being. We are convinced that this negotiation process must not be viewed as a traditional series of governmental trade-offs, but as an urgent international effort to safeguard human lives, homes, rights and livelihoods.
Ironically, it is only when disaster strikes that the shuttle makes the headlines. Its routine flights attracted less media interest than unmanned probes to the planets or the images from the Hubble Telescope. The fate of Columbia (like that of Challenger in 1986) reminded us that space is still a hazardous environment.
Economics is a choice between alternatives all the time. Those are the trade-offs.
Especially once those poetry events began, because, yeah, the stuff was still on the page, but the page was starting to spill into real space, spill into air, once you could hear it, once there was a typewriter, once there was a body of a typist, it was getting rid of the confines of the page.
In order to survive, all systems must evolve by providing greater and greater access to the currents that flow through them. This applies to all physical, biological and social systems that survive and thrive.... But let’s take that one step forward... the systems just described are ... constantly evolving. This suggests another design principle: ... design for evolution rather than creating a static design optimizing for the present.
Our ancient yogis and sages were not just medical healers, but systems scientists and systems engineers, who saw the body and the universe as an interconnected engineering system, a system of systems that are governed by fundamental engineering systems principles.
I'm urging NASA to foster the development of what I call 'runway landers.' No, that's not the name of a high stakes gambler from Vegas. It's a type of spacecraft that flies to orbit like the retiring Shuttles but then glides to a landing like an airplane on a runway. Just like the Shuttles do.
You can't exceed the system with language. You can only exceed the system with events; recommended procedures that are better. You can't exceed the system by telling people to be good, be kind, be considerate... You have to take away the conditions that makes it necessary for you to be kind. And to be kind, you design highways that aren't slippery; where no accidents, or less accidents, occur. In the future, everybody becomes an innovator - a creator.
