Sixteen of today's greatest unsolved mathematical puzzles in a story-driven, illustrated volume that invites readers to peek over the edge of the unknown.

Most people think of mathematics as a set of useful tools designed to answer analytical questions, beginning with simple arithmetic and ending with advanced calculus. But, as Mage Merlin's Unsolved Mathematical Mysteries shows, mathematics is filled with intriguing mysteries that take us to the edge of the unknown. This richly illustrated, story-driven volume presents sixteen of today's greatest unsolved mathematical puzzles, all understandable by anyone with elementary math skills. These intriguing mysteries are presented to readers as puzzles that have time-traveled from Camelot, preserved in the notebook of Merlin, the wise magician in King Arthur's court.

Our guide is Mage Maryam (named in honor of the brilliant young mathematician, the late Maryam Mirzakhani), a distant descendant of Merlin. Maryam introduces the mysteries--each of which is presented across two beautifully illustrated pages--and provides mathematical and historical context afterward. We find Merlin confronting mathematical puzzles involving tinker toys (a present for Camelot's princesses from the sorceress Morgana), cake-slicing at a festival, Lancelot's labyrinth, a vault for the Holy Grail, and more. Each mystery is a sword awaiting removal from its stone, capturing the beauty and power of mathematics.

does the job!
I bought the DXXULL 4-in-1 Cigar Tube as a gift for my husband, and overall, it’s been a solid choice. He travels often and enjoys cigars, so this compact, all-in-one tube really suits his lifestyle. The aluminum alloy feels sturdy and well-made, and the built-in cigar punch, hygrometer, and holder add a nice touch of convenience. It’s sleek and functional—he’s used it several times already without any issues. While I do think it’s a bit overpriced for its size, the quality and thoughtful design make up for it. If you’re looking for a practical, stylish gift for a cigar lover, this tube does the job well.

won't fit Churchill length or 60-ring diameter cigars
Color: Gold, Color: Gold
This is a good-looking device, solidly built, with a handy twist-out punch in the top and a humidity gauge in the bottom. The hygrometer is pointless, because there is no way to add anything to actually maintain the humidity, and since I would only use it to bring a cigar to a gathering, it really does not need to maintain that humidity for the 20-minute drive. What really bugs me about this is the actual useable size. I primarily smoke 2 types of cigars, 54-ring Churchills (which are 7") and 60-ring Gorditos (which are 6"). Although the overall length of this is 8 1/4", the listing never mentions the interior space, which seems to be just under 6 1/2" when closed. My Montecristo sticks out about 1/4" when I insert it, and that does not take into account the 1/4" that the top pushes into when closed (that silver-colored area is solid), thus less than 6 1/2" useable length. Even out of the wrapper, my 60-ring Gorditos sticks when I try to push it in, so I'd have to take off the band(s) to force it in, and it would not slide out very easily, so I would mangle the cigar trying to get it out. So, this can hold a cigar that is 6" or less and maybe 54-ring without the wrapper. Anything else, and you would have to force it in and force it out. So, this unit, while very good looking and well built, does not work for my cigar needs.

What an incredible value and amazing quality!
When this came up, I had to get it! I have several differrent cigar cutters, punches, and other accessories, but none compare to this one! It feels like a high quality knife, but is a cigar tool that does it all. I thought it was weighted, but was only the quality steel and components I was feeling in my hand. I took it to the cigar store I go to and asked if they had seen anything like this. They said yes, but are usually $75+ when you find them. It opens in your palm with a simple squeeze between the fingers and palm. The steel feels like quality in your hand, and when you open it and see both a V and standard cutter as the main parts, it seems like that's all it does. Nope.....it also has a poker on one side and a circle punch that folds out on one end. It is so easy to use and is something you will want to show your cigar smoking friends, as well as sharing it with them. It works extremely well and is an incredible value at this price. Highly recommended for any cigar smoker!
