While small, the Church of the Holy Mother of God is notable for its unusual architectural style, in particular for its high narthex flanked by two sharp-pointed towers. These features, which hint at Hungarian or Transylvanian influences, are highly atypical for medieval Bulgarian church architecture. The church is richly decorated on the inside, with as many as eleven frescoes of historical figures. One of these portraits, captioned as a despot, is variously identified as an eponymous son of Bulgarian tsarMichael Shishman or as an undocumented son of co-tsar Michael Asen IV; earlier speculation that the image depicted Serbian noble Mihailo Anđelović or Michael Shishman himself have since fallen out of favor with art historians. In addition to these early portraits, the interior walls of the church were painted with canonical murals, which can stylistically be assigned to the 14th–15th century. The church was reconstructed in 1958 and has been under Serbian state protection since 1982. (Full article...)
Born and raised in the Austrian Empire, Tesla first studied engineering and physics in the 1870s without receiving a degree. He then gained practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry. In 1884 he immigrated to the United States, where he became a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His AC induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company eventually marketed.
