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.

Nice grinder set
Size: 2.5" x 5.1"
These are a really pretty grinder set. They work well, but after a bit they don't grind as well, and the tops try to come off. They are also NOT dishwasher safe. They will literally melt, even on the top shelf.

Perfect Size & Price
Size: 2.5" x 5.1", Size: 2.5" x 5.1"
Perfect size! Easy to hold and turn the grinder. Grinds both S & P well. Easy to fill and comes with a top to cover grinder when not in use. Perfect look and style for a table or to store for easy reach beside your stove. It also come with 2 extra replacement grinders if needed. An excellent product at a reasonable price! See pic for a size comparison next to a solo cup.

These are great!
Size: 2.5" x 5.1"
I've had these for about a year year and a half and I really like them this morning the salt shaker broke, so I just ordered another set (they're not sold individually) to replace the one that broke. If you should happen to drop them on the floor the plastic top will crack!!

Great addition in my kitchen
Size: 1.7" x 5.1"
I really like these grinders. They are perfect size. I use them for other seasonings that I want to grind up for marinating or cooking. They are adjustable so if I want larger or smaller grinds, easily do-able. Great value for the price. They look nice and are easy to use. Also easy to clean.

Doesn't last
Size: 2.5" x 5.1", Size: 2.5" x 5.1"
This grinder appeared to work great and is one of the few ceramic options available. Unfortunately, the ceramic grinder has already broken inside, detaching from the bottle altogether. There are probably tiny plastic pieces in my leftover peppercorns. Don't buy it unless you want to purchase it every few months, which is unfortunate.
