Title: "Extra Dimensions"
Abstract: There are several theoretical hints, from high energy particle
physics and (quantum) gravity, that our world contains extra space
dimensions that are somehow invisible and have escaped detection so far.
Their size can be arbitrary. From the smallest possible one, ~10^{-33}
cm, up to infinite extent, various possibilities are suggested with
different theoretical motivations. An overview of the most popular and
better motivated scenarios is given.
