Well known through the work of Buckminster Fuller, models of spherical polyhedral excite the imaginations not only of mathematicians, architects and engineers but also of artists and designers. This book, concerned with polyhedrons, sphere tilings, and dome structures, offers a well-illustrated, practical approach to creating a host of beautiful and interesting models, including starfaced spherical forms that can serve as basic structures for geodesic domes.Employing only the most elementary mathematical principles, the text initially provides complete instructions for making spherical models from five regular solids, using only circular bands of paper, a ruler and a compass. Also discussed is tessellation, or tiling, on a sphere and how to make spherical models of all the semiregular solids. The volume concludes with a discussion of the relationship of polyhedral to geodesic domes and directions for building models of the domes.
Abundantly illustrated with photographs, drawings, and computer graphics of attractive geometrical models, this volume will appeal to a wide range of readers--from students and teachers of mathematics, art, design, architecture and engineering, to recreational mathematics enthusiasts and builders of geodesic domes.

Great, except for the edible one
Flavor Name: Chicken & Original, Size: X-Small
My elderly dog and my puppy both love these bones. They are 9lbs and 4.5lbs respectively and this is a good size for them. They also like the next size up and it is manageable for them as well.
The only gripe I have is the edible one, it comes apart in larger chunks (that are still very hard) and my dogs swallowed a few before I noticed how large the pieces were. I decided to throw that one away. Its been over a week and no negative side effects so maybe just me being overly cautious. For the price (gold box) just the other two bones were worth it. They last pretty much forever for my dogs, and I would say they are moderate chewers.
4 stars due to the issue with the edible bone.

My little dog loves these.
Flavor Name: Bacon & Peanut Butter, Size: X-Small, Flavor Name: Bacon & Peanut Butter, Size: X-Small
These are the perfect size, texture, and density for my 9 lb chihuahua (rescued, of course! :)) He has a tiny mouth with tiny teeth and very little bite force so he needs a chewybone with a lot of give. I've been impressed with how clean these help keep his teeth (it's the saliva flow during the chewing that breaks down any lingering debris and the action of the nubs against the teeth and gums helps to rub off tartar and plaque, if you care to know the *why* behind it.) These are ideal for dogs like mine, and since small dogs tend to have a lot of dental problems due to overcrowded mouths, I couldn't be more grateful that these exist. These would probably also be good for the many rescued puppy mill dogs, who are often small breeds, who have dental issues due to malnutrition and exacerbated by overbreeding, especially in females whose bodies often rob the jaw bones of calcium for the sake of the fetuses they carry, when the pregnant dogs aren't given an appropriately enriched gestational diet. That leads to the little bleppy tongues sticking out all over that we often see in the canine survivors of back yard breeding operations, puppy mills, and the like. There are a lot of these dogs being rescued and adopted in the U.S. right now and these would likely be ideal for them. (In case any adopters of these little survivors are reading this. :)) These are for gentle chewers only, and there are a lot of dogs who fall into that category. They aren't , however, for dogs with an average bite or higher, which is where some of the complaints you hear about these are coming from. Know your dog's chewing needs and buy the size that fits their mouth, tooth type, and bite strength. My dog barely puts a dent in these after a year or more of chewing (watch for any degradation of the plastic and replace as needed, of course.) For little dogs like mine, these are just fantastic and I hope Nylabone keeps making these type of chew toys to keep our dogs healthy. :)
