Indeed. The need for rigor often means certain parts of an argument get emphazised when they distract from the intuitive explanation. Also, when things get mathematically people have an urge to show how it connects to other mathematical results. Those connections are interesting in their own right, but they might not be related to the engineering problem at hand. The result is that understanding the literature can involve a long hard slog through other literature, just to discover that most of what you read was irrelevant. This is what it is often easier to discover things in the lab than in the library.
