Question

Initially mentioned in a 1906 trade magazine, later described in Dorothy Levitt's book "The Woman and the Car", then used in Ray Harroun's racing car, what did Elmer Brigg call it after he patented it in 1911?

Answer 1

Recognise the Ukrainian Orthodox Church as independent of the Russian Orthodox Church
The Ukrainian Orthodox Church had been linked with, and under the jurisdiction of, the Russian Orthodox Church and had resisted for more than 300 years. A formal split between the Orthodox churches in the two countries, seen as part of a wider history of political tensions between Russia’s geopolitical ambitions in the region and Ukraine’s resistance to them, came to a head in 2018. The tomos was signed in the Ecumenical Patriarchate of Constantinople which heads the Eastern Orthodox Church for Christianity. The change in classification for the Hagia Sophia happened in 2020.
