Although not a mathematician myself, I find math endlessly fascinating about for the way one can take a seemingly impossible problem and translate it or express it in another context, and all of a sudden that hard problem can become easy. Of course, you have to make the right choice of a new context, a task which is itself not always easy or predictable. And "easy" may be relative. Still, when it works, the result is intriguing and inspiring.
