An Introduction to the Geometry of N DimensionsFor many years, this was the only English language book devoted to the subject of higher dimensional geometry. While that is no longer the case, it remains a significant contribution to the literature, exploring topics of perennial interest to geometers. In the first four chapters, author D. M. Y. Sommerville explains the fundamental ideas of incidence, parallelism, perpendicularity, and angles between linear spaces. Chapter V presents analytical
For many years, this was the only English-language book devoted to the subject of higher-dimensional geometry. While that is no longer the case, it remains a significant contribution to the literature, exploring topics of perennial interest to geometers.In the first four chapters, author D. M. Y. Sommerville explains the fundamental ideas of incidence, parallelism, perpendicularity, and angles between linear spaces. Chapter V presents analytical geometry from the projective point of view, exploring some of the simplest ideas relating to algebraic varieties and offering a more detailed account of quadratics. Chapter VI examines analytic geometry of n dimensions from the metric point of view. The remaining four chapters deal with polytopes and address some of the elementary ideas in analysis situs. Chapter VIII treats the content of hyper-special figures, and the final chapter establishes the regular polytope.

Cute - change footbed please
Size: 8.5, Color: Dense Smoke
These are so comfy and fit my usually 8.5 foot great. It's the footbed of UGGs that I keep hoping they'll change. It's like our memory foam mattress - cushy and great UNTIL THE HEAT comes! Then it's a no for this hot 65 yo G'ma!

Super fun!
Size: 8.5, Color: Red Pepper
These are so fantastic! The color is amazing! It is a bit on the tomato-red side of the color-wheel. The fit is great. They are comfortable from the 1st step. Easy to walk in.

Nice so far.
Size: 6.5, Color: Molasses
Comfy. They were tight the first day across the toes but as I've worn them a couple times they are loosening up. The sole is forming to my foot. These are very much like Doc Martin's from the early 2000s. Not sure about quality since I haven't had them for very long.
