Philosophy of science is a branch of philosophy that explores the fundamental questions about the nature of scientific knowledge, the methods by which it is acquired, and the assumptions underlying scientific practices. It examines issues such as how scientific theories are developed, tested, and justified, the nature of scientific explanation, the relationship between science and other forms of knowledge, and the ethical implications of scientific research. Philosophers of science seek to illuminate the underlying principles and assumptions that guide scientific inquiry and to evaluate the validity and reliability of scientific claims. This field of study bridges the gap between philosophy and the natural sciences, offering critical reflection on the nature and significance of scientific knowledge.
