A thermal imager works by converting the radiation wavelengths (even smaller then visible light) into images in the camera, scope or computer. These images typically allow thing with more heat (higher radiation, and or higher wavelength) to show in brighter colors so that you can tell if things are hot by the color.
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.
