Science is a methodical and evidence-based approach to understanding the natural world. It involves making observations, conducting experiments, and formulating hypotheses that can be tested through empirical data. By analysing this data, scientists can develop theories and models that explain various phenomena and help us make predictions about the world around us. The scientific method is used across a wide range of fields, including physics, chemistry, biology, and astronomy, to name a few. Through scientific inquiry, we can deepen our understanding of the universe and develop technologies that benefit society.


Empirical data is information that is collected through observation or experience rather than through assumptions or beliefs. It’s based on evidence that can be measured or documented, which is important in science because it allows scientists to test their ideas and theories. Empirical data is essential for scientific research because it helps to provide objective evidence that can be used to validate or invalidate hypotheses. Scientists use a variety of methods to collect empirical data, such as experiments, surveys, and observations, to learn more about the natural world.

Science is an incredibly vast and complex field of study that covers a wide range of topics, but they all share a common goal of seeking knowledge and understanding about our world. Although the list of domains presented here is limited, it offers a glimpse into the immense diversity of scientific fields that exist.
