You take your pencil, and improvise, searching for inspiration... Suddenly you find it, and it opens the doors to a brand new artistic world to explore (it does this for me when I compose in the music studio).

Well, here it is the same thing. Questions leads to research, that lead to answers. And each new answer opens a new world to explore, which provokes an avalanche of new questions!

Like in art, in science, the important is not the destination, but the journey ;-)!
