Scientific knowledge refers to the information, facts, theories, and principles that have been gathered through systematic experimentation, observation, and research in various fields of science. This knowledge is supported by evidence, reproducible results, and logical reasoning, and it is constantly evolving as new discoveries are made and existing theories are refined or disproved. Scientific knowledge is organized into different disciplines such as biology, chemistry, physics, and astronomy, and it forms the foundation for technological advancements, medical breakthroughs, and our understanding of the world around us. Scientists use this knowledge to develop hypotheses, conduct experiments, and make predictions about the natural world.
