In his book Hyperspace
physics professor Michio Kaku
introduces readers to phenomena that occur in ten or twenty-six dimensions.
To prepare for this leap into higher space, he invites his audience to
imagine the plight of a two-dimensional creature trying to understand the
third dimension. The Flatland analogy still works!
Prof. Kaku is the author of many works on physics and its relationship to
other sciences, including ecology, as described on the WBAI web page for
his weekly national
science radio show. The
Frequently Asked
Questions list from that page answers a number of common questions
about physics and higher dimensions.
Numerous other writers have provided ways of looking at the structure of
the universe from the point of view of mathematical physics.
