PREAMBLE: I'm not asking you to do this for me, just point me to some CLEAR references.(adsbygoogle = window.adsbygoogle || []).push({});

THE PROBLEM: I am trying to understand the differences between Action-at-a-distance (AAAD) and Field theory. I am trying to better understand relativistic dynamics and the relativistic 2-body problem. I'd like to do 3 items:

1)A clear def'n of AAAD (that does not use the term "field"). Paraphrasing various definitions, I typically see that an example of AAAD relates to a "field", such as the gravitational "field" or the electrical "field".

2)A clear def'n of a field.

3)A table that contrasts AAAD and fields. For example:

ITEM, AAAD, Field

Dgrs of Freedm, 3N, Infinite,

Momentum, Mechanical, body to body, Field momentum

Mechanics,,, Hamiltonian, Lagrangian

Clearly, I am struggling to find the right words and phrases, and I understand there is some overlap in definitions and I understand that I have not clearly specified the items in the rows.

Thanks for any help or references you can give.
