David Lloyd George leaving Downing Street
Lloyd George pictured leaving Downing Street after his resignation with his wife and daughter Megan. His resignation announcement featured in the Court circular of 19th October. Lloyd George was the president of the Board of Trade between 1905-1908 and became the Chancellor of the Exchequer in 1908. His most popular move was to pass the Old Age Pensions Act and the National Insurance Act. He superseded H. H Asquith as coalition Prime Minister, 1916-1922, successfully handling peace negotiations after the war. In 1921 he came upon his most controversial agreement with Sinn Fein for the independence of Southern Ireland. His popularity faded and his party was undecided about their support. In 1922 Lloyd George handed in his resignation.

Nuclear fission, artwork
Nuclear fission. Conceptual computer artwork of an atom being split through nuclear, or atomic, fission (splitting). Electrons (orange) can be seen orbiting the nucleus (centre), made up of protons (yellow) and neutrons (blue). Nuclear fission is a reaction in which the nucleus of an atom is split into smaller parts. This often causes free neutrons to be emitted (lower right, blue) and results in lighter nuclei. The splitting of the nucleus can produce a vast amount of energy, used for nuclear power and nuclear weapons.

Lava entering the sea at night
Lava entering the sea at night. Night-time glow and clouds of steam produced by lava entering the sea on the coast of a volcanic island. Lava is molten rock that rises from beneath the Earth's surface. It is hot enough to glow red and vaporise water, turning it instantly to steam. Eventually, the sea water will cool the lava, and new volcanic rock will form. If the rate of eruption of lava is greater than the rate of erosion by the sea, then the island will grow in size. This lava flow is from the Kilauea volcano on the Pacific island of Hawaii. The Hawaiian islands are volcanic in origin, composed of the rock produced by successive volcanic eruptions.
