What is the primary focus of science as a field of study?

The primary focus of science as a field of study is the exploration and understanding of nature. This encompasses a wide array of subjects, including but not limited to biology, chemistry, physics, and earth sciences. Through systematic observation, experimentation, and analysis, scientists aim to uncover the underlying principles and laws that govern the natural world. This foundational emphasis on empirical evidence and the scientific method is what differentiates science from other fields of knowledge, such as history, mathematics, or philosophy, which may not rely as heavily on direct observation of natural phenomena. By focusing on nature, science seeks to explain how things work, the relationships between different elements of the natural world, and to develop predictive models that can be tested through further investigation.
