For example, there are a great many books explaining quantum mechanics to non-physicists, but without the math one simply cannot understand QM. Most fields are like that. One needs the background and tools to grasp them, and simplified explanations are necessarily imperfect compromises. But they should be as accurate as possible without overly complicated matters to the degree that non-professionals cannot grasp them.
