There isn't really a single "two meanings" of science. It's more accurate to say that the word "science" has different aspects or scopes depending on the context. Here are two common perspectives:

1. Science as a process: This refers to the systematic and empirical methods used to acquire knowledge about the natural world. It involves observation, experimentation, hypothesis testing, and the development of theories based on evidence. This is the core of what scientists do.

2. Science as a body of knowledge: This refers to the accumulated knowledge gained through scientific inquiry. It includes facts, theories, laws, and principles that have been established through rigorous scientific investigation. This is the "product" of the scientific process.

So, while these two aspects are distinct, they are ultimately intertwined. The process of science leads to the accumulation of knowledge, and that knowledge informs and guides further scientific investigation.

Here's an analogy: Imagine a house. The process of building the house involves gathering materials, using tools, and following blueprints. The body of knowledge is the house itself, a finished structure built with specific materials and a specific design.
