What do physicists mean when they talk about higher dimensional spaces, or space-times? How could we possibly not have noticed if space was not three-dimensional? In this first part, we will talk about the history of spaces with extra dimensions and how they became connected to dreams of unified theories, especially Kaluza-Klein theory, its achievements and its problems. Next week, we continue with the modern theories of additional dimensions of space.
