Much of what is built today will barely last a lifetime ...

Buildings, roads, bridges are repeatedly repaired, replaced, and demolished.  We seem to have the technology to make better materials; engineering sophistication to make things last; but not the foresight to put quality ahead of short-term cost considerations.  The TV breaks, it is cheaper to toss it out and buy a new one.  Plastic plumbing components are replacing copper products that are now so cheaply made that they have become undependable.  This says something about the current state of engineering AND our "civilization".

Lessons of failure

Professor Petroski's point about learning from failure is an important one. A recent book, "Creating Innovators: The Making of Ypung People Who Will Change the World," makes a similar point. In a Wall Street Journal op-ed, the author, Tony Wagner, writes, "In most high school and college classes, failure is penalized. But without trial and error, there is no innovation." Professor Petroski puts that lesson in historical context when he describes how ancient Egyptians, Romans and Greeks built a body of engineering knowledge by learning from failure.

Still readable

Henry, one comment you made really resonated with me.  You mention that Vitruvius's book is still eminently readable.  I find that all the time.  It is interesting to go back to read source material (as opposed to contemporary commentaries) on any subhject and to see how much like those authors we are.  Despite all the great innovations we have developed, we still think in similar ways.  In some ways that seems suprising.  I guess it should not. 

A wile back I was in Germany and our hosts were showing us a Roman aqueduct that was still in operation.  It is really a testament to their knowledge and skill.  We build on that foundation and reap the benefits.

Latest Analysis
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
