Continental drift plate tectonics theory. In particular, the English geologist Arthur Holmes proposed in 1920 that plate junctions might lie beneath the sea, and in 1928 that convection currents within the mantle might be the driving force. Holmes' views were particularly influential: in his bestselling textbook, "Principles of Physical Geology," he included a chapter on continental drift, proposing that Earth's mantle contained convection cells which dissipated radioactive heat and moved the crust at the surface. Holmes' proposal resolved the phase disequilibrium objection (the underlying fluid was kept from solidifying by radioactive heating from the core). However, scientific communication in the '30 and
Centre for the Study of World Christianity Centre for the Study of World Christianity The Centre for the Study of World Christianity (CSWC) is a research centre based in New College, the School of Divinity at the University of Edinburgh. It was founded in the University of Aberdeen by Andrew F. Walls as the Centre for the Study of Christianity in the Non-Western World in 1982, but later moved by Walls to the University of Edinburgh in 1986. Its current name was adopted in 2009. The Centre is currently directed by Brian Stanley. The Centre promotes historical, theological, and social scientific research in the field of World
