Gauge redundancy arises in physical theories when certain configurations are physically equivalent. Symmetry, on the other hand, refers to invariance of a physical system under a transformation. In gauge theories, the gauge redundancy leads to local symmetries that leave physical observables unchanged.

What are the key principles and concepts of gauge physics?
Gauge physics is a branch of theoretical physics that deals with the fundamental forces of nature. The key principles and concepts of gauge physics include gauge symmetry, gauge fields, and gauge invariance. Gauge symmetry refers to the idea that the laws of physics should remain unchanged under certain transformations. Gauge fields are mathematical constructs that describe the interactions between particles, such as the electromagnetic field. Gauge invariance is the idea that the choice of gauge, or mathematical framework, should not affect the physical predictions of a theory. These principles are essential for understanding the behavior of particles and the fundamental forces that govern the universe.
What is the difference between absolute and gauge pressure?
Absolute pressure is measured relative to a perfect vacuum, while gauge pressure is measured relative to atmospheric pressure.
What is the net force on the force gauge?
If the force gauge isn't moving, the the net force must needs be zero.
What are the fundamental principles and applications of gauge theory in theoretical physics?
Gauge theory is a framework in theoretical physics that describes the interactions between fundamental particles. It is based on the idea of symmetries and how they affect the behavior of particles. The fundamental principles of gauge theory include the concept of gauge symmetry and the gauge field, which mediates interactions between particles. Applications of gauge theory in theoretical physics include the Standard Model of particle physics, which describes the electromagnetic, weak, and strong nuclear forces, as well as theories of gravity such as general relativity.
What is the difference between absolute and gauge pressure measurements?
Absolute pressure measurements include atmospheric pressure as a reference point, while gauge pressure measurements do not account for atmospheric pressure.
