**Physics, Astronomy & Cosmology / Can we say a bit about fields in physics?**

« **on:**26/11/2018 22:56:26 »

I understand that a field can be defined as a series of measurements over an area,the type of measurements involved determining the nature of the field .

So how many types of field are there ? Is he number of them simply limited by our imagination or rather are there just a few corresponding to fundamental physical properties such as gravity , electro-magnetism ,temperature etc?

Could we imagine a density field for example ? An age field?

Are there circumstances where 2 kinds of field "overlap" or even interact?

And is it true to say that ,even though a field can be seen as a mathematical model that this does not mean that it does not stand as a representation of a physical object ?(so that ,for example ,the gravity field can be seen to represent a physical object)
