Fields: In physics, a field is a physical quantity that has a value at every point in space and time. Fields can be classified as scalar, vector, or tensor fields, depending on whether the physical quantity they represent is a scalar, vector, or tensor, respectively.

Hennig Genz on Fields - Dictionary of Arguments

II 105
Field/Genz: Field has replaced the ether. It is something that assigns numbers to every place and time, for example, temperature distribution. The field is the assignment itself. Here you need a number per location
For example, wind distribution: here you need two numbers per location: one for strength and one for direction.
Field/Abstraction/Genz: as an abstraction the field is no problem.
Problem: that there are fields that represent the last reality. There is no material substrate here.
Reality/Genz: the term is thus forced to change.
Field/immaterial: light, for example, can simply be abstract field sizes that oscillate when light propagates, which cannot be traced back to any material reality.
II 106/107
Fields: e.g. the speed of a river from shore to shore, e.g. angle of inclination of grasses of a meadow, e.g. the speed of the clouds, e.g. the ups and downs of points of a violin string, e.g. the bow wave of a ship (a moving deformation) e.g. alignment of iron chips by a magnet.
Reality/Genz: we attribute them to fields when they obey equations that describe them.
>Equations
, >Reality.
Maxwell's equations/Genz: (for electric and magnetic fields): Maxwell's equations only differ from the equations describing water currents in their mathematical details.
Mathematical substrate/Fields/Genz: mathematical substrate could not be found. Thus the fields became more and more the last reality.
Field: creates its particles! And they always have to.
>Substrate.
II 108
Therefore, there is no empty space without fields.
Fields: are not a substrate of vibrations, but the vibrations themselves. This is also the reason why elementary particles of the same type are always absolutely identical.
Field/Newton: his theory did not use any fields, but instead had to assume instantaneous propagation, i. e. long-distance effect.
>Isaac Newton.
Transmission/gravity/Field/Genz: the body that exerts an effect usually has already left the place when the force begins to act. For example, the sun is standing in a place 8 minutes away from where it was standing when the effect was exerted by it.
Field: one has tried to eliminate fields by assuming the effect of particles on particles. This turned out to be extremely complicated, especially since one had to explain time delay.
II 109
Gravitation/Field/Genz: gravity can transfer energy (impulse and angular momentum). Therefore, a theory that would only know cause and effect instead of fields would have to override conservation laws during transmission (?).
Fields/Genz: the same applies to all fields.
>Gravitation.
Existence/Field/Genz: whether they exist is a pointless question outside the theories which accept them. The status of the fields can only be described by if-then sentences.
II 115
Field/Genz: Fields can never be completely absent. They have to fluctuate by zero. In their basic state they disappear net but not gross.
Material property/object/thing/Genz: that fields must always be present may appear to some as a possible property of a material thing, but not to others.
Material/matter/Genz: when something is material, it forms a medium in relation to which an observer is always in a measurable speed.
Field/Genz: for fields in the ground state, however, the theory implies that this is impossible, since an observer determines his speed in relation to it.
>Matter, >Observation.
