Classroom-tested and much-cited, this concise text offers a valuable and instructive introduction for undergraduates to the basic concepts of topology. It takes an intuitive rather than an axiomatic viewpoint, and can serve as a supplement as well as a primary text.A few selected topics allow students to acquire a feeling for the types of results and the methods of proof in mathematics, including mathematical induction. Subsequent problems deal with networks and maps, provide practice in recognizing topological equivalence of figures, examine a proof of the Jordan curve theorem for the special case of a polygon, and introduce set theory. The concluding chapters examine transformations, connectedness, compactness, and completeness. The text is well illustrated with figures and diagrams.

The brackets were exactly what I had in mind, and at a much more affordable price than Home Depot. They are sturdy and look amazing!

Nice brackets
Size: 11.25 Inch, Number of Items: 8, Size: 11.25 Inch, Number of Items: 8
The brackets look great and fit a 1x12 board perfectly. They've been installed for a few days and seem to be sturdy.
So far, the only negative is the hardware, as other reviewers have mentioned. Initially, I had some trouble locating the stud and decided to use the drywall anchors. I got one bracket installed and the anchor was already pulling out of the wall.
Overall, I think the brackets are great, but just use your own screws and drywall anchors (if needed).

I bought these for an alcove. The brackets came in great condition. I didnt notice any scratched.
Mounting… the brackets are not centered on the wall, but are centered on the studs. I cant do anything about the stud placement.
I bought a 2x8x10 board and cut it into 40 in sections. After placing the brackets on the wall the boards fit beautifully in place. (I used the long stud screws that came with the brackets)
I havent screwed the boards to the wall (those screws also included) and may not. I like being able to pull a board out and run cables behind, if needed. I think the boards are sturdy enough that I wont have an issue with tipping, since the right most stud is at the corner of the wall.
