A clear-headed command of logic can make the mind powerful enough to outmaneuver the devil himself, according to these intriguing stories. More than 200 puzzles, problems, and paradoxes await within these pages, woven together by a wizard's captivating narrative. The Sorcerer -- so skilled in the art of logic that his reasoning seems like magic -- takes a puzzle-based perspective on the principles underlying the works of mathematician Georg Cantor. His fascinating riddles involve probability, certainty, time, and infinity, and they unfold amid a landscape populated by honorable knights, lying knaves, quick-witted robots, and other fanciful characters.Amusing and enlightening, the Sorcerer's guided tour of infinity is geared toward the most dedicated puzzle-solvers. Although many of the solutions require only common sense, equations appear in several of the stories, and a familiarity with algebra is essential. The author of several imaginative books on recreational mathematics, Raymond Smullyan is a well-known mathematician and logician. He provides solutions within text, rather than at the end or in footnotes, offering readers a natural progression on a puzzle-filled path through the wonders of logic.

If the set screws were white the shelves would be perfect.
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 15.7inches
I'd give 4 1/2 if there was one. The shelves thwmself are nice I just don't like the visible little black set screws. The shelves themself look great and are not wobbly at all if you install correctly. I purposely installed the bracket upside down because of the little black setting screws; I didnt want them showing because the shelves are above eye level and the screws are black and I didn't want them showing. But that made the shelf lean amd wobbly so I turned them back over the way they are supposed to be and that made them level and sturdy. I guess I'll paint the little screws.

Did its job for moderate weight items.
Size: 40 Inch, Color: Black, Number of Items: 1
Easy install, a little expensive for its construction. Nice appearance however, flexes under moderate weight not for heavy items.

Great addition!
Size: 40 Inch, Color: Rustic Brown, Number of Items: 1
Floating shelf was super easy to install and is a great addition above my window in my office. I used it to put some display pieces my wife wouldn’t allow me to put over our mantle. Very sturdy and looks great!
