I am interested in the input from the physics community on quantum field theory. If each particle has an associated field of which they are manisfestations what causes a particle to arise from a field?

This isn't the physics community.

Jeeze... come on guys. This is a serious question. I, for one, would like to know the answer. Can we dispense with the personal battles?

I have this book. What I am tired of getting is people telling me to read books. That is because you have no ability to think yourself. I have many books I could recommend to you that would allow you to really begin to think but I don't. I rely on my own ability to reason. I don't care what some guy wrote in a book. He could be completely wrong. The problem is that you people and the physics world in general have no understanding of reason and what criteria are needed to establish something as existing.

Could you mention any further reading on this.

so why do you say things like:

Somehow particles arise from this field perhaps by converting some of the field energy into mass which are related by E=mc^2 or something similar.

...do [virtual particles] violate conservation of energy?

Is your explanation of how a "particle" arises from a field considered to be generally accepted and definitive(minus detailed equations) within the mainstream physics community?

Has stability of virtual particles been experimentally achieved through the application of external force fields or other mechanisms, or is this still speculative?
The ontological status of fields in QFT refers to the philosophical debate surrounding the nature of these fields. Some argue that they are real, physical entities that exist in space and time, while others argue that they are mathematical constructs used to describe the behavior of particles.
In QFT, fields interact through the exchange of virtual particles. These virtual particles are constantly being created and destroyed, mediating the interaction between particles and causing the fields to change and evolve over time.
Fields themselves cannot be directly observed in QFT, as they are mathematical constructs. However, their effects can be observed through the behavior of particles, which are influenced by the fields they interact with.
In quantum mechanics, fields are used to describe the behavior of particles and their interactions. They are essential in understanding the fundamental nature of matter and energy at the subatomic level.
In classical physics, fields are treated as continuous and smooth, while in QFT they are described as discrete and quantized. Additionally, classical fields are deterministic, while in QFT there is an inherent randomness due to the uncertainty principle.
