I understand (at least to a comfortable degree) dimensions which are less than or equal to 3. For the past several years, I have been hearing a lot about four dimensional space. I'm intrigued and would like to learn more but, I do not know where to start.
Any breadcrumbs would be appreciated.
Edit: What I mean by understanding 3-dimensional space is that I can comprehend concepts like l*w*h. I am not remotely in the ballpark of being a geometer (in fact I just learned the term) or topologist.
I've done coursework in statistics, pre-calculus, finite, and discrete; I imagine that stats and finite won't help me here. These courses were all several years ago. I'm not opposed to a long journey if that is necessary. I am just looking for a path to the material. I hope this makes sense. Please let me know if further clarification is needed; I'll try my best.
