Here's why:
* It's a method: Science is a process, not a tangible thing. It's a set of guidelines for how we investigate the world around us.
* It's about concepts: Scientific knowledge is built on abstract concepts like gravity, energy, evolution, etc. These concepts are not directly observable, but we can use them to explain and predict phenomena.
* It's a body of knowledge: While science relies on concrete data, the overarching principles and theories are abstract constructs that help us understand the data.
However, science also deals with concrete things:
* Data: Scientific research is based on concrete data collected through experiments and observations.
* Materials: Scientists work with real materials, equipment, and specimens.
* Applications: The results of scientific research have concrete applications in technology, medicine, engineering, and other fields.
In short, science is both abstract and concrete. It's a system of abstract concepts and methods that we use to understand the concrete world around us.
