I have always taken the expression "common sense" to mean things that are obvious to anyone except a fool. That is quite different from the expression referencing "conventional wisdom", or it's equvalent, "common thinking", which refelects the unverified assumptions that are usually based on sources less reliable than gossip. 

Common sense dictates that one would not stick a hand into the cutting area of a lawnmower, or stand on the very top of a folding ladder. Common sense is that wisdom that lawyers seem to dictate that it is not reasonable to expect their client to posess.

@Ann: The Italian writer Antonio Gramsci drew a distinction between common sense and good sense.

To Gramsci, "common sense" meant the ruling ideology of a society: the ideas that are generally accepted without much critical thought.  As such, "common sense" is not universal, but may be radically different in different times and places (according to Gramsci, mainly depending on who's in charge).

"Good sense," on the other hand, requires critical thought.

"Common sense" might contain some elements of "good sense," but they are very different things.

Dave's comment about "intuitively obvious" makes me think of how many times I've been told that a certain practice is "common sense." My response is always "common to which group?" The term implies shared values and meanings, and shared assumptions about how the world does and should work. But these are not so common In a modern complex society.

Another great article from Professor Craig.  The only part I take issue with is the claim that "the grey-box modelling approach is intuitive and obvious." First of all, our intuitions can often mislead us.  Read The Invisible Gorilla, by psychologists Chris Chabris and Dan Simons, for many instructive examples of everyday illusions.  Second, if these things were obvious, there would be no need for engineers... let along engineering professors!

On the subject of modelling the real world, take a look at Dan Meyer's blog.  Dan is a high school math teacher who gave a though-provoking TED Talk called Math Class Needs a Makeover.  Dan puts modelling at the center of his teaching.  It's an approach that can help prepare students to engage in engineering problem-solving.

FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
“How can European standards affect me, especially since I only use machines built in the US?” This is a common question, and one way to answer this is to look at how machine safety is enforced, where the information comes from, and how well you can prove you followed the regulations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
While people may talk about the procurement process, the procurement discipline actually encompasses a number of different processes. They include spend analysis, supplier relationship management, and contract management, just to name a few.
As the Industrial Internet of Things and machine-to-machine communications movements gain speed, some companies are asking themselves, “Wait. How much information do we really want to flow in and out of our premises? Aren’t we supposed to be doubling down on cyber security?”
