The Heian period (, Heian jidai?) is the last division of classical Japanese history, running from 794 to 1185. The period is named after the capital city of Heian-kyo, or modern Kyoto. It is the period in Japanese history when Buddhism, Taoism and other Chinese influences were at their height. The Heian period is also considered the peak of the Japanese imperial court and noted for its art, especially poetry and literature. Although the Imperial House of Japan had power on the surface, the real power was in the hands of the Fujiwara clan, a powerful aristocratic family who had intermarried with the imperial family. Many emperors actually had mothers from the Fujiwara family. Heian (?) means "peace" in Japanese.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does heian mean in Japanese?
Ah, so.. peace

In 1872, Russian Alexander Lodygin invented an incandescent light bulb and obtained a Russian patent in 1874. He used as a burner two carbon rods of diminished section in a glass receiver, hermetically sealed, and filled with nitrogen, electrically arranged so that the current could be passed to the second carbon when the first had been consumed. Later he lived in the USA, changed his name to Alexander de Lodyguine and applied and obtained patents for incandescent lamps having chromium, iridium, rhodium, ruthenium, osmium, molybdenum and tungsten filaments, and a bulb using a molybdenum filament was demonstrated at the world fair of 1900 in Paris.

Ah, so.. two carbon rods

The Region of Ile de France, including Paris and its surrounding communities, is governed by the Regional Council, which has its headquarters in the 7th arrondissement of Paris. It is composed of 209 members representing the different communes within the region. On December 15, 2015, a list of candidates of the Union of the Right, a coalition of centrist and right-wing parties, led by Valerie Pecresse, narrowly won the regional election, defeating a coalition of Socialists and ecologists. The Socialists had governed the region for seventeen years. In 2016, the new regional council will have 121 members from the Union of the Right, 66 from the Union of the Left and 22 from the extreme right National Front.
