Discussion Overview

The discussion centers around the nature of fields, specifically electric fields, and whether they are composed of particles or waves. Participants explore concepts related to field interactions, the implications of these interactions on classical physics, and the definitions of fields in physics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions whether fields, particularly electric fields, are made up of particles or waves, and suggests that this could challenge the accuracy of Newtonian physics.
  • Another participant agrees that opposing fields create a force that moves them apart and references wave-particle duality as a relevant concept.
  • A different participant interprets the idea of particles colliding with equal momentum as a basis for cancellation of energies, linking it back to the discussion of fields.
  • One participant argues that fields do not cancel each other out but rather bend and deflect when interacting, emphasizing that fields are not matter but rather areas where forces are experienced.
  • This participant also describes fields metaphorically as spring-like entities that can be bent or pulled, suggesting they possess potential energy in interactions.

Areas of Agreement / Disagreement

Participants express differing views on the nature of fields and their interactions, with no consensus reached on whether fields are composed of particles or waves, or how they behave when interacting.

Contextual Notes

Some assumptions about the definitions of fields and the implications of Newtonian physics are not fully explored, and the discussion does not resolve the complexities of wave-particle duality or the nature of forces in field interactions.

Yesterday I was thinking about electric fields and how similar fields, when intersecting, push away and 'deflect' each other. If we were to take two fields of equal magnitude (and charge since I am using an electric field as an example) and have them make contact they should cancel each other out right? But that's according to Newtonian physics where p=mv. So my question is: are fields generally made up of particles or waves and if they are made of waves doesn't an observation like this prove that most of Newtonian physics is probably inaccurate?

As you stated initially, opposing fields will create a force, moving them apart. Also, why is p = mv relevant? A book on wave-particle duality may be what you're looking for in this case. Newtonian Theory is considered inaccurate at cosmological scales (where it is superseded by relativity) and in the atomic world, were Newton's laws also break down, and are replaced by quantum theory.

by P=mv i was thinking about the concept that if they are particles and they hit each other with equal momentum then they should 'cancel' each others energies out.
 
I believe that fields don't really "cancel" each other out. If you draw a typical diagram of an electric field of two charges approaching each other, u should end up with the fields being "bent" and deflected by the other field.

And, fields are not matter. All fields are by definition "an area in which a (whatever, be it magnet, charge, etc) experiences a (some kind of ) force".

To me, I think of fields as spring like thingies which get bent or pulled when affected by another field, which gives them "potential energy" to pull or push back and thus accounts for forces caused by interactions of fields. But, still, they are not matter.
