Do Judge a Book by Its Cover - initial ideas

The book I've chosen is a study of ray guns and lasers in real life science and science fiction media, and while most of it is interesting, it is also full of heavy equations to do with things like light refraction that I will never understand. I've focused on imagery of science fiction for my initial ideas as that's the side of this book that interests me. I think that this is a good starting point for my roughs and I have a few ideas I'd like to move forward with, especially the thought of having a cover with ray guns from popular culture arranged around the title in a graphic design style. Id also like to further develop the idea of incorporating the mix of an equation and a laser gun into the design as it would represent the books grounding in both science and fiction.
