Diamond

In mineralogy, diamond (/ˈdaɪəmənd/ or /ˈdaɪmənd/; from the ancient Greek ἀδάμας – adámas "unbreakable") is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at standard conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells.

Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green (radiation exposure), purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors).

District

A district is a type of administrative division that, in some countries, is managed by local government. Across the world, areas known as "districts" vary greatly in size, spanning entire regions or counties, several municipalities, subdivisions of municipalities, school district, or political district.

By country

 Afghanistan

In Afghanistan, a district (Persian / Pashto: ولسوالۍ‎ Wuleswali) is a subdivision of a province. There are almost 400 districts in the country.

 Australia

Electoral districts are used in state elections. Districts were also used in several states as cadastral units for land titles. Some were used as squatting districts. New South Wales had several different types of districts used in the 21st century.

Austria

In Austria, a district (Bezirk) is an administrative division normally encompassing several municipalities, roughly equivalent to the Landkreis in Germany. The administrative office of a district, the Bezirkshauptmannschaft, is headed by a Bezirkshauptmann. It is in charge of the administration of all matters of federal and state administrative law and subject to orders from the higher instances, usually the Landeshauptmann (governor) in matters of federal law and the Landesregierung (state government) in state law. While there are matters of administrative law the municipalities themselves are in charge of, or where there are special bodies, the district is the basic unit of general administration in Austria. Officials on the district level are not elected, but appointed by the state government. There are also independent cities in Austria. They are called Statutarstadt in Austrian administrative law. These urban districts do have the same tasks as a normal district.

Lost Cause of the Confederacy

The Lost Cause is a set of beliefs common in the white American South in the late 19th and early 20th century. While it was not taught in the North it did win acceptance there and helped the process of reunifying American whites. The beliefs portray the Confederate cause as a heroic one against great odds despite its defeat. The beliefs endorse the virtues of the antebellum South, viewing the American Civil War as an honorable struggle for the Southern way of life, while overlooking or downplaying the central role of slavery.

Yale Professor Roland Osterweis summarizes the content that pervaded "Lost Cause" writings:

The Lost Cause belief was founded upon several historically inaccurate elements. These include the claim that the Confederacy started the Civil War to defend states' rights rather than to preserve slavery, and the related claim that slavery was benevolent, rather than cruel.
