Precisely

The definition of stupidity is doing the same thing over and over again and expecting different results. Albert Einstein

You've heard this definition of stupidity, right? But what we should say, in most cases, is that it is doing the same thing over and over and expecting the same the results. For us engineers, we know that no matter how hard we try, if we make one thing and then another of the same thing, the two will be different. Make a third, fourth, and so on and these will be different as well. If all of the things we make are "close" to the same, then we are, at least, precise. If they are "close" to what we want them to be, then we are accurate. Accurate is getting it right. Precision is being consistent.

"Why did this subject even come up?," you ask as you move closer to the edge of your seat to hear the answer. Well, it all comes from the situation pictured below. This is a NOTPHOTOSHOPPED snapshot taken in the cafeteria where I work. So, just where do you think this project stands in terms of accuracy and precision?

Several hundred engineers work in this building. Did they think we would not notice?
