In cosmology and astronomy the phenomena of stars, nova, supernova, quasars and gamma-ray bursts are the universe's highest-output energy transformations of matter. All stellar phenomena (including solar activity) are driven by various kinds of energy transformations. Energy in such transformations is either from gravitational collapse of matter (usually molecular hydrogen) into various classes of astronomical objects (stars, black holes, etc.), or from nuclear fusion (of lighter elements, primarily hydrogen). The nuclear fusion of hydrogen in the Sun also releases another store of potential energy which was created at the time of the Big Bang. At that time, according to theory, space expanded and the universe cooled too rapidly for hydrogen to completely fuse into heavier elements. This meant that hydrogen represents a store of potential energy that can be released by fusion. Such a fusion process is triggered by heat and pressure generated from gravitational collapse of hydrogen clouds when they produce stars, and some of the fusion energy is then transformed into sunlight.
What is driven by various kinds of energy transformations?
stellar phenomena

Most of the Korean Presbyterian denominations share the same name in Korean, 대한예수교장로회 (literally means the Presbyterian Church of Korea or PCK), tracing its roots to the United Presbyterian Assembly before its long history of disputes and schisms. The Presbyterian schism began with the controversy in relation to the Japanese shrine worship enforced during the Japanese colonial period and the establishment of a minor division (Koryu-pa, 고려파, later The Koshin Presbyterian Church in Korea, Koshin 고신) in 1952. And in 1953 the second schism happened when the theological orientation of the Chosun Seminary (later Hanshin University) founded in 1947 could not be tolerated in the PCK and another minor group (The Presbyterian Church in the Republic of Korea, Kijang, 기장) was separated. The last major schism had to do with the issue of whether the PCK should join the WCC. The controversy divided the PCK into two denominations, The Presbyterian Church of Korea (Tonghap, 통합) and The General Assembly of Presbyterian Church in Korea (Hapdong, 합동) in 1959. All major seminaries associated with each denomination claim heritage from the Pyung Yang Theological Seminary, therefore, not only Presbyterian University and Theological Seminary and Chongsin University which are related to PCK but also Hanshin University of PROK all celebrated the 100th class in 2007, 100 years from the first graduates of Pyung Yang Theological Seminary.
In what year did the Korean church celebrate the 100th class?
2007

The climate of Cork, like the rest of Ireland, is mild and changeable with abundant rainfall and a lack of temperature extremes. Cork lies in plant Hardiness zone 9b. Met Éireann maintains a climatological weather station at Cork Airport, a few kilometres south of the city. It should be noted that the airport is at an altitude of 151 metres (495 ft) and temperatures can often differ by a few degrees between the airport and the city itself. There are also smaller synoptic weather stations at UCC and Clover Hill.
