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
Battle of Rorke's Drift a touring English Northern Union rugby league team defeated Australia 14–6 to win the Ashes in the final Test match. Depleted by injuries and fielding only ten men for much of the second half, the English outclassed and outfought the Australians in what quickly became known as the 'Rorke's Drift Test'. In 1914, the Edison Company made a two-reel silent film titled Rorke's Drift starring Richard Tucker. The 1964 film "Zulu" produced by Stanley Baker is a depiction of the Battle of Rorke's Drift. The film received generally positive reviews from the critics. Some details of the film's account are,
