Context paragraphs:
Lean's Engine Reporter: Lean's Engine Reporter was founded in 1810 to publicize the performances of different Cornish engines used for mine pumping in Cornwall.  The first Reporter of Duty was Joel Lean.  The Reporter, published monthly, gave, for each engine and its pumps, the number of strokes (measured by a counter kept in a locked box), and the amount of coal used.  From this, and sizes of the pumps, the engine duty was found: this was the number of pounds of water raised one foot by a bushel of coal.  Between 1810 and 1840 this reporting, and competition between engineers, raised the duty from around 20 million to 90 million pounds, a much higher efficiency than found in engines elsewhere at the same time.  The improvements were an increase in the steam pressure used, full expansion to low pressure, and insulation to avoid heat loss.

Grunge speak: Grunge speak was a hoax created by Megan Jasper, then receptionist for Sub Pop Records.  Under pressure from a reporter for "The New York Times" who wanted to know if grunge fans had their own slang, Jasper, 25 at the time, told the reporter a set of slang terms that she claimed were associated with the Seattle grunge scene in the early 1990s, but which she had in fact invented on the spot.  The information given by Jasper appeared in the sidebar of a November 15, 1992, feature article by reporter Rick Marin in the "New York Times".  The sidebar, titled "Lexicon of Grunge: Breaking the Code," mistakenly said that Jasper was working for Caroline Records.

Robert H. Scanlan: Robert H. Scanlan (1914-2001) was a civil and aeronautical engineer who came to be widely recognized as a leader in the analysis of wind effects on large structures.  Scanlan created the concept of flutter derivatives to aid in the representation of self-excited forces in theoretical models.  His research in the area of bridge aerodynamics made possible the construction of larger, sturdier, and more cost-effective bridges.  Scanlan worked in both industry and academia, and his employers included Republic Aviation, the Federal Aviation Administration, the French agencies CNRS and ONERA, Schlumberger, the Case Institute of Technology, Princeton University, and Johns Hopkins University.  In the course of his life, Scanlan published two textbooks, "Aircraft Vibration and Flutter" and "Wind Effects on Large Structures," which are used by engineers worldwide.

Wake Forest Demon Deacons: The Wake Forest Demon Deacons are the various sports teams of Wake Forest University.  Originally, Wake Forest's athletic teams were known as the Fighting Baptists, due to its association with the Baptist Convention (from which it later separated itself).  However, in 1923, after a particularly impressive win against the Duke Blue Devils, a newspaper reporter wrote that the Deacons "fought like Demons", giving rise to the current team name, the "Demon Deacons".

The Temptations of Jean-Claude Killy: "The Temptations of Jean-Claude Killy" is an article published in the premiere issue of "Scanlan's Monthly" in March 1970, written by Hunter S. Thompson.

The Kentucky Derby Is Decadent and Depraved: "The Kentucky Derby Is Decadent and Depraved" is a seminal sports article written by Hunter S. Thompson on the 1970 Kentucky Derby in Louisville, Kentucky, first appearing in an issue of "Scanlan's Monthly" in June of that year.  Though not known at the time, the article marked the first appearance of gonzo journalism, the style that Thompson came to epitomize through the 1970s.

Gonzo journalism: Gonzo journalism is a style of journalism that is written without claims of objectivity, often including the reporter as part of the story via a first-person narrative.  The word "gonzo" is believed to have been first used in 1970 to describe an article by Hunter S. Thompson, who later popularized the style.  It is an energetic first-person participatory writing style in which the author is a protagonist, and it draws its power from a combination of social critique and self-satire.  It has since been applied to other subjective artistic endeavors.

Scanlan's Monthly: Scanlan's Monthly was a short-lived monthly publication, which ran from March 1970 to January 1971.  The publisher was Scanlan's Literary House.  Edited by Warren Hinckle III and Sidney Zion, it featured politically controversial muckraking and was ultimately subject to an investigation by the FBI during the Nixon administration.  It was boycotted by printers as "un-American" by 1971.  According to the publishers more than 50 printers refused to handle the January 1971 special issue "Guerilla War in the USA" because it appeared to be promoting domestic terrorism.  The issue was finally printed in Quebec and in a German translation in Stuttgart ("Guerilla-Krieg in USA", Deutsche Verlagsanstalt 1971).  The magazine produced a total of eight issues during its existence.
