Working Up

by Dwayne Phillips It is difficult to measure things from a distance. That distance can by in space and it can be in time. We often attempt to measure things from a distance. We take photos of the ground from 10,000 feet up in the air. We then run through geometric calculations to determine the […]

by Dwayne Phillips A change in the behavior of a system means that someone has changed something. We as people, often love to ignore this. Here is a situation I experienced a few years ago in a digital signal processing laboratory. One day, a piece of software didn’t work. A user ran the software, and […]

by Dwayne Phillips Any change to a situation will change the situation. It is often difficult to discern which came first. When a new person walks into an existing group of people, that group changes. There is no way around this—at least I know of no way around it. To have a new person without […]

by Dwayne Phillips Accepting something that is false leads us all into all sorts of trouble. There is a property in logic that states if you accept something that is false, you can prove anything. For example, if you accept that one equals zero, you can prove anything in math (try it). Recently, I stumbled […]

I tried in vain to convince people that was a misguided goal. […]

by Dwayne Phillips The napkin or envelope is still one of the best tools for the engineer or manager or fill-in-the-blank. I have a(n old-fashioned) laptop computer, a smartphone, and a tablet – and I still write notes on a napkin. Yes, I am old, that is part of the explanation. Yet, there is something […]

by Dwayne Phillips Why do we do that? I find two answers to that question. The world is not complicated – at least if viewed from certain perspectives. Why do we burn fossil fuels? Why do athletes use steroids? Simple answer: because they work. But we move on to observing people do things that don’t […]

by Dwayne Phillips I write an oft-repeated tale of factory with two occupants and one control mechanism. There are these urban myths. People tell a story over and over. It sounds pretty good, plausible, it could happen. Then I hear someone else in a completely different time and place tell the same story about a […]
