In THE BOOK OF NUMBERS, two famous mathematicians fascinated by beautiful and intriguing number patterns share their insights and discoveries with each other and with readers. John Conway is the showman, master of mathematical games and flamboyant presentations; Richard Guy is the encyclopedist, always on top of problems waiting to be solved. Together they show us why patterns and properties of numbers have captivated mathematicians and non-mathematicians alike for centuries. THE BOOK OF NUMBERS features Conway and Guy's favorite stories about all the kinds of numbers any of us is likely to encounter, and many others besides. "Our aim," the authors write, "is to bring to the inquisitive reader. . .an explanation of the many ways the word 'number' is used." They explore patterns that emerge in arithmetic, algebra, and geometry, describe these pattern' relevance both inside and outside mathematics, and introduce the strange worlds of complex, transcendental, and surreal numbers. This unique book brings together facts, pictures and stories about numbers in a way that no one but an extraordinarily talented pair of mathematician/writers could do.Binding Type: Hardcover

Not indestructible, but well worth it
Color: GT-2P, Color: GT-2P
First things first…it’s solid, literally. Very hard and if you have tile or wood floors, it’s ridiculously loins when it hits the floor. With that said, we’ve had our dogs chewing on these for about a month now. All 3 are aggressive chewers. As you can see in my pic, there are signs of chewing on the ends of the bone. I’ve noticed they all seem to gravitate towards them assuming they think they can chew through it. Not the case. The material itself made of is hard but I almost think they enjoy the feeling of the bone against their teeth and gums. I regularly watch our biggest chewer lay on the couch for what seems like hours just biting on it. The bone itself has held up extremely well and haven’t shown any signs of splintering, breaking, or falling apart. This making us feel the bone is safe considering how much they love to chew and how well it’s held up. It looks like a bone. This seems to be a factor in them wanting and/or seeking it out when they want to chew on something. Great to keep close in the living room and gets almost immediate engagement from all of them when I pull it out. Well worth it if you have problem dogs that chew everything and anything. Great as a distraction and from what we’ve seen, great for hours of engagement. Highly recommend for sure.

Excellent toy for aggressive chewer dogs!!!
Color: GT-2P, Color: GT-2P
These treats are super heavy duty! My German shepherd is a good eater. This includes chewing on many things that are not make to be dog toys. I need to keep her occupied and chewing toys that are made specifically for aggressive chewers. She’s quite wily and can usually take apart those supposed aggressive chewers toys very fast. That’s why I love these toys. They actually are for aggressive chewers and keep my best friend busy chewing for days! I love that you can add soft treats or doggy toothpaste to the grooves in these. The raised bumps on the toy are also supposed to help clean teeth. A dog toy that helps with bad breath? I will take two please! Plus, love that these can be cleaned easily, even in the dish washer, and have long lasting bacon scents that my girl loves.
In all seriousness, these are strange looking but very functional chew toys. They do not make a mess (other than my dog drooling all over - haha). You can even add doggy peanut butter! Perfect for big dogs and aggressive chewers. I would caution against using for any elderly dog and or dog that doesn’t have strong teeth.
Good value for the price (a little over $5 each on sale) considering how long these toys last. Also a good gift.

Dog approved!
My dogs love this. This is the 3rd time I have bought them. They are entertained for hours and keeping their teeth strong.
They pay me no attention when they have this toy. 😂

Our Dog Loves This One
We got our dog two nylabones and this benebone and he really prefers this one. Like the nylabones he barely even looked at, but he loves this one so much it's starting to splinter off a little. Apparently it can just be sanded down again but I'll probably end up getting more of these so that we can switch them out. I noticed that the shape also helps him be able to handle it with his paws.
