You have to create two images. One for old resolution and one for retina display. If I remember, you have only to add @x2 on retina images.
For web you can still use the @2x naming convention. Declare the background image and set the size. In the retina display media query call the high-res image.
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.
