Mathematical and Computing Sciences Question #12

Ken Cooke, a 53 year old male from the Internet asks on May 14, 1999,

I read somewhere there are a total of 9 dimensions. Can you elaborate on what these dimensions are? There is length, width, height and the fourth is time. What are the others?

In fact there are an infinite number of dimensions after the fourth dimension of time. (Space is defined by the first 3 dimensions.) It does not stop at nine. The higher dimensions can represent many possible things. For instance I have seen them used to represent possible connections in a complex telephone network. They can be used to understand the many phases of modern radio signals. Or how about the unusual nature of time and space inside a black hole? Higher dimensions have countless applications in physics, math, and engineering to name just a few.
