Full Idea
The word 'field' is simply a shorthand way of saying that a physical property is assigned to the points of space and time in a region.
Gist of Idea
A 'field' is just a region to which points can be assigned in space and time

A Reaction
This is disappointing because I had begun to think that fields were foundational for modern ontology. Turns out they are operational abstractions (according to Martin). Note that a field extends over time.
