Use this information to start off defining concepts: Concept data.
These are concepts that are much bigger than everyday experience. We don't have to have direct everyday experience of the phenomena in order to develop these theories, but measurements made in a variety of ways that support existing ideas allow us to have high confidence in our knowledge of these concepts.
These are concepts that are to do with the things we see around us everyday. Some of these concepts seem logical and obvious, others often confuse us as when we look in detail at the concept we realise they don't follow common sense. These concepts are all measurable and accessible to us in our everyday lives.
