In reference to version 224734d7be7ff0c4a8adb3a206356ea122112f33 i am just enjoying reading the chapters and this line quote grabbed my attention - and wanted to convey my thoughts!

Our geometric objects will be something like 13-dimensional planes in R 27 , etc. It is amazing that we can say anything substantive about objects that we cannot directly visualize.

Very well written!

thanks!
