August 6, 1915 — The Battle of Lone Pine begins

The Battle of Lone Pine – or, if you’re Turkish, the Battle of Kanli Sirt – was a five day long engagement between the ANZAC forces and the Turkish defenders during the Gallipoli campaign of 1915. Part of a larger Allied Assault called the August Offensive, it was about the only successful one, where Australian forces captured their objectives, reinforced them and held them against the Turkish counter-attack. Unfortunately, after August 10, 1915, conditions returned to the stalemate that had previously obtained on the Dardanelles front, and the assault would be abandoned entirely in December of that year.

But in August, 2200 Australians and 5000-6000 Turks were killed or wounded in action, and all for a few square miles of mud that had little impact on the wider conduct of the war. Seven Australians were awarded the Victoria Cross for their actions in the battle, for what it’s worth. Today, Lone Pine military cemetery is the site of commemorative services every ANZAC Day.

November 25, 1915 — Einstein’s General Theory of Relativity is published

One of the most revolutionary theories of physics of all time, Albert Einstein’s General Theory of Relativity turned the celestial mechanics of Isaac Newton on its head, and set the stage for the quantum mechanical revolution in physics that characterised the Twentieth Century. Along with Heisenberg, Bohr, Schrodinger, Feynmann and others, Einstein’s work changed the way we understand our world, but even in that august company, Einstein is a titan among giants, a man whose name has become a byword for genius.

The General Theory of Relativity resists easy summation. It was created to reconcile various anomalies in Newton’s theory of Universal Gravitation, as well as between Newton and Einstein’s earlier Special Theory of Relativity, and forms an important part of our current understanding of physics, gravitation and cosmology – the Big Bang Theory draws upon it, for example.
