Context paragraphs:
Chief of Air Staff (Ghana): Chief of Air Staff is the official title of the highest ranking air force personnel of the Ghana Air Force.  The current Chief of Air Staff is Air Vice Maxwell Mantsebi-Tei Nagai.

Line of force: A line of force in Faraday's extended sense is synonymous with Maxwell's line of induction.  According to J.J. Thomson, Faraday usually discusses "lines of force" as chains of polarized particles in a dielectric, yet sometimes Faraday discusses them as having an existence all their own as in stretching across a vacuum.  In addition to lines of force, J.J. Thomson—similar to Maxwell—also calls them tubes of electrostatic inductance, or simply Faraday tubes.  From the 20th century perspective, lines of force are energy linkages embedded in a 19th-century unified field theory that led to more mathematically and experimentally sophisticated concepts and theories, including Maxwell's equations, electromagnetic waves, and Einstein's relativity.

Grendizer: UFO Robot Grendizer (ＵＦＯロボ グレンダイザー , Yūfō Robo Gurendaizā ) , also known as "Force Five: Grandizer" in the United States, is a Japanese Super Robot anime television series and manga created by manga artist Go Nagai.  It is the third entry in the Mazinger trilogy.  It was broadcast on Japanese television from October 5, 1975, to February 27, 1977, and lasted 74 episodes.  The robot's first appearance in the United States was as a part of the Shogun Warriors line of super robot toys imported in the late 1970s by Mattel, then in Jim Terry's "Force Five" series, both under the title "Grandizer".  It is still widely popular in the Middle East, and it was especially popular in France and Quebec, as well as among French speaking Canadians in the province of New Brunswick, where it was aired under the title "Goldorak".  It was also very popular in Italy, where it was aired under the title "Goldrake", starting in 1978.

On Physical Lines of Force: "On Physical Lines of Force" is a famous four-part paper written by James Clerk Maxwell published between 1861 and 1862.  In it, Maxwell derived the equations of electromagnetism in conjunction with a "sea" of "molecular vortices" which he used to model Faraday's lines of force.  Maxwell had studied and commented on the field of electricity and magnetism as early as 1855/6 when "On Faraday's Lines of Force" was read to the Cambridge Philosophical Society.  Maxwell made an analogy between the density of this medium and the magnetic permeability, as well as an analogy between the transverse elasticity and the dielectric constant, and using the results of a prior experiment by Wilhelm Eduard Weber and Rudolf Kohlrausch performed in 1856, he established a connection between the speed of light and the speed of propagation of waves in this medium.

Samuel D. Maxwell: Samuel D. Maxwell (19 February 1803 in Garrard County, Kentucky – 3 July 1873) was the eighth mayor of the city of Indianapolis, Indiana.  Maxwell won three mayoral elections as a Republican Party candidate and held office from 1858 to 1863.  Maxwell is noted for his relationship with Governor Oliver Morten during the civil war.  Mayor Maxwell is also known for founding the Indianapolis Fire Department in the fall of 1859, taking it from a combination volunteer to all career department by creating a board to oversee the transition.  He appointed Joseph W. Davis as the first Chief Fire Engineer of the Fire Force.  Later a grandson, Samuel Anderson Maxwell would later serve on the Indianapolis Fire Department as a fireman in 1880.

Maxwell Nagai: Air Vice Marshal Maxwell Mantsebi-Tei Nagai is a Ghanaian air force officer and serves in the Ghana Air Force.  He is currently the Chief of Air Staff of the Ghana Air Force.

Demon Lord Dante: Demon Lord Dante (Japanese: 魔王ダンテ , Hepburn: Maō Dante ) is a manga series written and illustrated by Go Nagai.  The series tells the story of Ryo Utsugi, a student who discovers he is the reincarnation of an ancient demon known as Dante and sees himself in the middlle of a conflict between God and the devils.

A leading director at the Toei Animation studio during the 1960s, 1970s, and 1980s, Katsumata worked as a director on several of Toei's anime television adaptations of manga by Go Nagai, including "Devilman" (1972), "Mazinger Z" (1972), "Cutey Honey" (1973), "Great Mazinger" (1974), "UFO Robo Grendizer" (1975) and "Gaiking" (1976) (both Grendizer and Gaiking became later part of Jim Terry's "Force Five" package on U.S. television).

Nagai Naohiro: Nagai Naohiro (永井 直敬 , 1664 – July 18, 1711) was a Japanese daimyo of the Edo period, who ruled the Akō Domain following its confiscation from Asano Naganori.  Naohiro was the eldest son of Nagai Naotsune, and assumed family headship after his father's death.  Upon the confiscation of the Nasu clan's territory in Shimotsuke Province, Naohiro was transferred there from his previous holdings in Kawachi, and thus became the lord of the Karasuyama Domain.  Naohiro was appointed to the offices of jisha-bugyō and sōshaban in 1694, and in the fall of 1701, after the execution of Asano Naganori, he received a 3000 koku increase in stipend, becoming the new lord of Akō, with a territory of 33,000 koku.  However, because of the time-consuming nature of his work as jisha-bugyō, the domain's affairs were run by his retainers.  Naohiro subsequently became a wakadoshiyori in 1704.  He was moved to Iiyama in 1706, and Iwatsuki in 1711; Naohiro died soon after the move, in the summer of 1711.  His son Naohira succeeded to the family headship.
