Why can't I use eyepieces of increasingly higher magnification to achieve higher total magnification?

To maintain useful magnification with satisfactory clarity and resolution, you must avoid empty magnification or making the specimen appear bigger but not clearer. In general, total magnification should not exceed 750X-1000X the N.A. of the objective. For example, with a 40X, N.A. 0.65 objective, the total magnification should be between 480X and 650X.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
