response: I don't know the exact details. However, they are involved with different fields of research like biophysics and physics itself is not very concretely defined.
original_response: Physicists conduct experiments. It often intersects with many interdisciplinary  areas of research, such as biophysics and quantum chemistry
history: I have 3 physics classes this year and I know nothing about physics! Physics encompass a range of topics. There's studies about a variety of topics from matter to energy and force. I didn't even know that much lol I'm a total noob when it comes to physics. What else should I know? Well, the main goal of physics is to understand how the universe behaves. That sounds really complicated. How do physicists do that?
knowledge: Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined.
