References To History, Geography, and Science
The lunar action takes place in Mare Crisium and the novel makes accurate references to such nearby locales as Crater Peirce. According to the narrator, most people live in one of six major underground "warrens" linked by "tube", a system of underground trains. Luna City is the most important to the plot, and is "on the eastern edge of Mare Crisium". The Authority warren Complex Under is connected to Luna City by the "Trans-Crisium" tube. Johnson City is close to the complex, linked by a single tunnel. Novy Leningrad, a large warren, is linked to Luna City by tube, and a journey between the two requires the traveler to "change at Torricelli". Another warren is Tycho Under, whose location is clearly in the area of the crater Tycho. Hong Kong Luna is located in Crater Plato. The warren known as Churchill is not described in detail, although it is linked to Hong Kong Luna via a tube across the Sinus Medii on the Lunar Prime Meridian. The secret catapult is built in the region of Mare Undarum.
Colorado Springs is mentioned as near the military target Cheyenne Mountain which took a direct hit during the "Wet Firecracker War" but suffered little damage until hit many times by rock missiles from Luna.
The Headquarters of the Lunar Authority on Earth are in the city of Agra, near the Taj Mahal. The bombardment from Luna omits the city of Agra from its target list out of respect. Mannie, a New York Yankees fan, visits what is presumed to be Yankee Stadium, now expanded to hold at least 200,000 people; and also visits Salem and Concord in Massachusetts.
Lasers are used primarily as mining and cutting tools, but are adapted as hand weapons and ground-to-orbit weapons by the Loonies.
Luna's industries use both solar power and hydrogen fusion. Heinlein correctly quotes the maximum yield of solar cells at about 1 kilowatt per square meter, but is over-optimistic with regard to fusion, describing it as taking place in small magnetic pinch bottles.
Mannie refers to a comrade, Foo Moses Morris, who, following the revolution, becomes broke and starts a tailor shop in Hong Kong Luna; a reference to Robert Morris, who helped support the American revolutionary government and also suffered financial reverses.

Famous quotes containing the word science:
“For us necessity is not as of old an image without us, with whom we can do warfare; it is a magic web woven through and through us, like that magnetic system of which modern science speaks, penetrating us with a network subtler than our subtlest nerves, yet bearing in it the central forces of the world.”
—Walter Pater (18391894)
