M. Typography is the art and techniques of type design, modifying type glyphs, and arranging type.

Steve Jobs who I really respect said about connecting dots in his address.
He dropped out from his college and he took a course of typography that looked interesting. None of that had even a hope of any practical application in his life. But ten years later, when he was designing first Macintosh computer, it all came back to him. Of course it was impossible to connect the dots looking forward when he was in college. But it was very very clear looking backwards ten years later.
