There's a little bit of a misunderstanding in the question. "Physics principle" refers to a fundamental concept in physics, not a person.

Here's the breakdown:

* Physics: The scientific study of the fundamental constituents of the universe and the laws that govern their behavior.

* Principle: A fundamental truth or law that serves as a basis for reasoning or action.

So, a physics principle is a fundamental law or rule that describes how something in the universe works.

Examples of physics principles:

* Newton's Laws of Motion: These laws describe how objects move and interact with each other.

* The Law of Conservation of Energy: Energy cannot be created or destroyed, only transformed from one form to another.

* The Principle of Relativity: The laws of physics are the same for all observers in uniform motion.

* The Law of Universal Gravitation: Every particle in the universe attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Let me know if you'd like to know more about a specific physics principle!
