      The key to understanding and usage of Formal Methods is to realize that it is a way of thinking at many different levels. You can choose whatever level seems intuitive and accessible to you.

      Carroll Morgan's classic (In-)Formal Methods: The Lost Art --- A Users’ Manual and his recent book on the same are also relevant here - https://news.ycombinator.com/item?id=45490017
