Dear Ken & All, - When you talk about methods and methodology, do you talk about the basic character of the problem/s? - If you understand the character of the problem/s, do you feel of talking about 'class theoretical' and 'field theoretical'? - If classify the theoretical, do you determine what are the methods possible within that theoretical? - And then justify particularly which method will you adopt, and which you will not adopt with proper reason.........
