Today, we still refer to our work as empirical science, even though, at this point, there is often quite a distance between human sense-based experience and how data is collected. In both astronomy and physics, data collection typically involves complex equipment that is connected to extensive computer-based algorithms that convert the signals in the equipment into data that humans then analyse. Even so, we still treat this as a sensory process, with a heavy emphasis on what we can “eyeball” on…
