Here's why:

* Pure science focuses on understanding the fundamental laws of nature. It's driven by curiosity and a desire to expand our knowledge base, rather than immediate practical applications.

* It's about exploring new ideas, testing hypotheses, and generating new theories. This process of discovery leads to the accumulation of scientific knowledge.

* Examples of pure science:

* Studying the behavior of subatomic particles

* Investigating the origins of the universe

* Understanding the mechanisms of photosynthesis

In contrast, applied science aims to use that scientific knowledge to solve practical problems and develop new technologies.
