Reverse engineering is a term that is used for the process of taking apart something to figure out how to use it, basically. In many cases, something new and great has come about from it. In order to understand how it works or to recreate it, engineers will pull it apart and study it. Understanding how it works is one thing. But in order to recreate it, they will have to make it different somehow. This can be challenging but is often necessary. Reverse engineering is quite a fantastic way to learn new things.
