Human are used to living in 3D space, since our living environment (house, office, kindergarten, and more) is limited 3D space. This restricts our understanding to 3D space, not higher-order dimensional spaces. A direct understand of 4D space or higher is difficult. I am just wondering if it is possible to build a f-dimensional architecture in real world, with f being non-integer and over 3, e.g. f=3.2. If so, this could help the evolution of human.
