History and philosophy of science

History and philosophy of science is the study of how people have thought about and studied the natural world in the past. It is a way to look back at different ideas and theories that people had and how they affected the way we think and understand science today. It helps us understand how scientific theories have changed over time and why. It can also help us better understand why we do things the way we do today, and helps us see what questions we need to ask as scientists about our theories and research.
