I've been a student of Philosophy since childhood. The convergence of Science, Industry, and Math is of exceptional curiosity to me. Here is a video explaining the concept of measurement as a metaphor. Hope you like it. Measurement technologies reflect and extend what is known. Some people, like Rene Descartes and Sir Isaac Newton, believed that only those things that can be measured can be considered real. In their world if it cannot be measured, it doesn't exist. Measurement technologies are how we relate the unknown to the known. The 4 different kinds of measurement technologies reflect different kinds of understanding of the world or worldviews, not reality. To be technologically sane would be to incorporate these different world views. To be technologically insane would be to identify nature as data.
