History & Mathematics. Entropy and Destabilization. Yearbook: Grinin, Коротаев, Harper

The present Yearbook is subtitled Entropy and Destabilization. It is the tenth in the series. The study of the forms and causes of destabilization is extremely important, because no regime, no society, no system is immune to destabilization. Destabilization, or at least the threat of it, is an inevitable stage in the historical development of any society. The question is to what extent a society is capable of resisting it, how institutionalized and adap­tive it is. The articles of this issue are devoted to the various manifestations of destabiliza­tion, its different forms, patterns and causes in the past and present.
The issue consists of four sections: (I) Historical Aspects', (II) Social and Cultural Aspects-, (III) Factors of Destabilization', (IV) Reviews and Notes.
We hope that this issue will be interesting and useful both for historians and mathe­maticians, as well as for all those dealing with various social and natural sciences.
