Ice ageAn ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the ice age called Quaternary glaciation. Individual pulses of cold climate within an ice age are termed glacial periods (or, alternatively, glacials, glaciations, glacial stages, stadials, stades, or colloquially, ice ages), and intermittent warm periods within an ice age are called interglacials or interstadials.
Generation ZGeneration Z (often shortened to Gen Z), colloquially known as zoomers, is the demographic cohort succeeding Millennials and preceding Generation Alpha. Researchers and popular media use the mid-to-late 1990s as starting birth years and the early 2010s as ending birth years. Most members of Generation Z are children of Generation X or younger Baby Boomers. The older members may be the parents of the younger members of Generation Alpha.
Silent GenerationThe Silent Generation, also known as the Traditionalist Generation, is the Western demographic cohort following the Greatest Generation and preceding the baby boomers. The generation is generally defined as people born from 1928 to 1945. By this definition and U.S. Census data, there were 23 million Silents in the United States as of 2019. In the United States, the Great Depression of the 1930s and World War II in the early-to-mid 1940s caused people to have fewer children and as a result, the generation is comparatively small.
Michael Smith (newspaper reporter)Michael Smith (born 1952) is a British author who specializes in spies and espionage. He is also a former member of the board of the Bletchley Park Trust. Smith is a former soldier and journalist best known for obtaining and publishing the documents collectively known as The Downing Street Memos. The Downing Street memo itself was an official record of a meeting of the British war cabinet held in July 2002. It revealed the disclosure by Sir Richard Dearlove, then the head of the British Secret Intelligence Service (MI6), that the intelligence to justify an invasion was being "fixed around the policy".
Post-processual archaeologyPost-processual archaeology, which is sometimes alternately referred to as the interpretative archaeologies by its adherents, is a movement in archaeological theory that emphasizes the subjectivity of archaeological interpretations. Despite having a vague series of similarities, post-processualism consists of "very diverse strands of thought coalesced into a loose cluster of traditions". Within the post-processualist movement, a wide variety of theoretical viewpoints have been embraced, including structuralism and Neo-Marxism, as have a variety of different archaeological techniques, such as phenomenology.
The Affair at the Semiramis HotelThe Affair at the Semiramis Hotel is a 1917 detective novella by the British writer A. E. W. Mason featuring his character Inspector Hanaud. Mason had originally written many of the plot elements for an abortive silent film, to be called The Carnival Ball. The novella appeared between Mason's first full-length Hanaud novel, At the Villa Rose (1910), and his second, The House of the Arrow (1934). The story is set in London, after the events described in At the Villa Rose.

Peter ChurchillPeter Morland Churchill, (14 January 1909 – 1 May 1972) was a British Special Operations Executive (SOE) officer in France during the Second World War. His wartime operations, which resulted in his capture and imprisonment in German concentration camps, and his subsequent marriage to fellow SOE officer, Odette Sansom, received considerable attention during the war and after, including a 1950 film. Churchill's father was William Algernon Churchill (1865–1947), a British Consul who served in Mozambique, Amsterdam, Pará in Brazil, Stockholm, Milan, Palermo, and Algiers.
Little Ice AgeThe Little Ice Age (LIA) was a period of regional cooling, particularly pronounced in the North Atlantic region. It was not a true ice age of global extent. The term was introduced into scientific literature by François E. Matthes in 1939. The period has been conventionally defined as extending from the 16th to the 19th centuries, but some experts prefer an alternative timespan from about 1300 to about 1850. The NASA Earth Observatory notes three particularly cold intervals.
Generation XGeneration X (often shortened to Gen X) is the demographic cohort following the baby boomers and preceding the millennials. Researchers and popular media use the mid-to-late 1960s as starting birth years and the late 1970s to early 1980s as ending birth years, with the generation being generally defined as people born from 1965 to 1980. By this definition and U.S. Census data, there are 65.2 million Gen Xers in the United States as of 2019.
Generation AlphaGeneration Alpha (Gen Alpha for short) is the demographic cohort succeeding Generation Z. Scientists and popular media use the early 2010s as starting birth years and the early-to-mid 2020s as ending birth years . Named after alpha, the first letter in the Greek alphabet, Generation Alpha is the first to be born entirely in the 21st century and the third millennium. Members of Generation Alpha are mostly children of Millennials, and older Generation Z.
Direct currentDirect current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current.
