This book solves the long-standing mystery of a Christian monastery near Samarkand, seen and described by two Arab travellers in the tenth century. Despite several attempts made since the 1890s, its precise location had never been established. The first part covers the quest, the find, and the archaeological excavations’ results. Then the author proceeds to search for a mediaeval Christian enclave near modern Tashkent, which appears to have been washed away by a river that changed its course over centuries. Apart from the Christians, the book also touches upon the Manichaeans, Buddhists,...

This is a monograph on the fluctuational theory of superconductivity. The theory was originally developed by M. A. Savchenko in 1964 in response to the work of B. T. Matthias, the discoverer of superconductive compounds. Further development of the theory led to the prediction of the existence of high-temperature superconductors among magnetic and nonmagnetic compounds of rare-earth metals, ceramics, and polymers. In 1987 this prediction was experimentally verified by the discovery of high-Tc superconducting rare-earth metal oxides by I. Bednorz and K. Muller. To date, this is the only account...
