A manifold is a concept from mathematics. Making a manifold is like making a flat map of a sphere (the Earth). The Earth is a sphere, a three dimensional object of geometry. Yet, maps (two-dimensional representations) can be made of the Earth. At the edges of a certain map, the map needs to be changed. That way it is possible to make a two dimensional image of the whole surface of the Earth. Each manifold has a dimension. This is the dimension of the maps, in the example above. It is the same for all maps. https://simple.wikipedia.org/wiki/Manifold
