... and for one very brief moment it made me think about the relationship between the metrics and the substance and/or between the tools and the material. Some time ago I thought that all diagnostic tests are a wash because they are always going to give you the same thing no matter what you apply them to. They measure what we want them to measure and not what maybe should be measured but we haven't think of it yet. Simply put, clocks are the reflection of our view of the world. Not of the world itself.
