A few weeks ago I wrote that ‘engineering is all about ingenuity‘ [post on September 14th, 2016] and pointed out that while some engineers are involved in designing, manufacturing and maintaining engines, most of us are not. So, besides being ingenious, what do the rest of us do? Well, most of us contribute in some way to the conception, building and sustaining of networks. Communication networks, food supply networks, power networks, transport networks, networks of coastal defences, networks of oil rigs, refineries and service stations, or networks of mines, smelting works and factories that make everything from bicycles to xylophones. The list is endless in our highly networked society. A network is a group of interconnected things or people. And, engineers are responsible for all of the nodes in our networks of things and for just about all the connections in our networks of both things and people.
Engineers have been constructing networks by building nodes and connecting them for thousands of years, for instance the ancient Mesopotamians were building aqueducts to connect their towns with distance water supplies more than four millenia ago.
Engineered networks are so ubiquitous that no one notices them until something goes wrong, which means engineers tend to get blamed more than praised. But apparently that is the fault of the ultimate network: the human brain. Recent research has shown that blame and praise are assigned by different mechanisms in the brain and that blame can be assigned by every location in the brain responsible for emotion whereas praise comes only from a single location responsible for logical thought. So, we blame more frequently than we praise and we tend to assume that bad things are deliberate while good things are happenstance. So reliable networks are happenstance rather than good engineering in the eyes of most people!
