Pyrite

The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS₂. This mineral's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.

Pyrite is the most common of the sulfide minerals. The name pyrite is derived from the Greek πυρίτης (pyritēs), "of fire" or "in fire", in turn from πύρ (pyr), "fire". In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what we now call pyrite. By Georgius Agricola's time, c. 1550, the term had become a generic term for all of the sulfide minerals.

Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well as in coal beds and as a replacement mineral in fossils. Despite being nicknamed fool's gold, pyrite is sometimes found in association with small quantities of gold. Gold and arsenic occur as a coupled substitution in the pyrite structure. In the Carlin–type gold deposits, arsenian pyrite contains up to 0.37 wt% gold.

Last Week Tonight with John Oliver

Last Week Tonight with John Oliver, often abridged as Last Week Tonight, is an American late-night talk and news satire television program airing on Sundays on HBO in the United States and HBO Canada, and on Mondays (originally Tuesdays) on Sky Atlantic in the United Kingdom. The half-hour long show premiered on Sunday, April 27, 2014, and is hosted by comedian John Oliver. Last Week Tonight shares some similarities with Comedy Central's The Daily Show with Jon Stewart, where Oliver was previously featured as a correspondent and fill-in host, as it takes a satirical look at news, politics and current events on a weekly basis.

Oliver has said that he has full creative freedom, including free rein to criticize corporations. His initial contract with HBO was for two years with an option for extension. In February 2015, it was announced that the show has been renewed for two additional seasons of 35 episodes each. Oliver and HBO programming president Michael Lombardo have discussed extending the show from half an hour to a full hour and airing more than once a week after Oliver "gets his feet under him".
