and acknowledgments Self-organized criticality is a new way of viewing nature. The basic picture is one where nature is perpetually out of balance, but organized in a poised state-the critical state-where anything can happen within well-defined statistical laws. The aim of the science of self-organized criticality is to yield insight into the fundamental question of why nature is complex, not simple, as the laws of physics imply. Self-organized criticality explains some ubiquitous patterns existing in nature that we view as complex. Fractal structure and catastrophic events are among those regularities. Applications range from the study of pulsars and black holes to earthquakes and the evolution of life. One intriguing conse- quence of the theory is that catastrophes can occur for no reason whatsoever. Mass extinctions may take place without any external triggering mechanism such as a volcanic eruption or a meteorite hitting the earth (although the the- ory of course cannot rule out that this has in fact occurred). xu How Nature Works Since we first proposed the idea in 1987, more than 2, ooo papers have been written on self-organized criticality, making ours the most cited paper in physics during that period. How Nature Works is the first book to deal with the subject. The basic idea is simple, and most of the mathematical models that have been used in the implementation of the theory are not complicated.Binding Type: Hardcover

My yorkie destroyed
It says it’s very durable so that’s why I bought it although the body and ropes are good the ears on the horse came off in the first day with my small dog so be careful with the ears and other looser things on the animals. The rope untied many times as well not a big deal I just knotted it back but she still loves this toy so it’s okay I’m my book just watch for ripping of ears and other parts on the head of this toy

Head and body ripped after less than 5 min of tug
Color: Scrunch Bunch Bunny, Color: Scrunch Bunch Bunny
The seam beteeen the head and body failed after less than five minutes of supervised tug with a 35 pound dog. This is NOT a tough toy. No reinforced stitching.
Absolutely unsafe - a dog could easily rip open the neck and get at the squeakers, which are small enough to be swallowed and lodged in an intestine.

Good but not as tough as advertised
Color: Scrunch Bunch Duck
My dog absolutely loved this toy. He was obsessed immediately! It was his (and our) first crinkle toy. He loves the crinkle though it’s a bit distracting for me as it kind of sounds like he’s getting into something he shouldn’t. I love that there are two squeakers, one in the belly and one in one of the handles to squeak on during tug of war. Though he enjoys this toy, the head ripped off during a mild tug only about a few hrs after delivery. My dog is a medium sized 25 lb dog, he is not super strong or a super chewer by any means so I was surprised that it tore so easily. The fabric itself seems strong enough to withstand mild chewing but the seams aren’t as tough as they are advertised. If you don’t mind mending your dogs toys, it’s a very fun toy that’s easy to play with your dog as the handles work well for tug of war, just keep in mind that anything over a small sized dog will probably tear this toy apart during a play session.

dogs love this one
Pattern Name: Uni-Hippo
In a 4 dog household we go through a lot of toys. My dogs love the size and weight of this toy. Very well built, light, and durable. I like that there was no squeaker. Good price for a durable toy.
