The centimetre–gram–second system of units is a variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time. All CGS mechanical units are unambiguously derived from these three base units, but there are several different ways in which the CGS system was extended to cover electromagnetism.
Feminist science fiction is a subgenre of science fiction focused on such feminist themes as: gender inequality, sexuality, race, economics, reproduction, and environment. Feminist SF is political because of its tendency to critique the dominant culture. Some of the most notable feminist science fiction works have illustrated these themes using utopias to explore a society in which gender differences or gender power imbalances do not exist, or dystopias to explore worlds in which gender inequalities are intensified, thus asserting a need for feminist work to continue.
Science fiction and fantasy serve as important vehicles for feminist thought, particularly as bridges between theory and practice. No other genres so actively invite representations of the ultimate goals of feminism: worlds free of sexism, worlds in which women's contributions are recognized and valued, worlds that explore the diversity of women's desire and sexuality, and worlds that move beyond gender.
A utopia typically describes an imaginary community or society that possesses highly desirable or near-perfect qualities for its members. It was coined by Sir Thomas More for his 1516 book Utopia, which describes a fictional island society in the New World.
The Dispossessed is a 1974 utopian science fiction novel by American writer Ursula K. Le Guin, one of her seven Hainish Cycle novels. It is one of a small number of books to win all three Hugo, Locus and Nebula Awards for Best Novel.

Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points. In a static electric field, it corresponds to the work needed per unit of charge to move a positive test charge from the first point to the second point. In the International System of Units (SI), the derived unit for voltage is the volt (V).
Brave New World is a dystopian novel by English author Aldous Huxley, written in 1931 and published in 1932. Largely set in a futuristic World State, whose citizens are environmentally engineered into an intelligence-based social hierarchy, the novel anticipates huge scientific advancements in reproductive technology, sleep-learning, psychological manipulation and classical conditioning that are combined to make a dystopian society which is challenged by the story's protagonist. Huxley followed this book with a reassessment in essay form, Brave New World Revisited (1958), and with his final novel, Island (1962), the utopian counterpart. This novel is often compared as an inversion counterpart to George Orwell's 1984 (1949).
Utopian and dystopian fiction are subgenres of speculative fiction that explore social and political structures. Utopian fiction portrays a setting that agrees with the author's ethos, having various attributes of another reality intended to appeal to readers. Dystopian fiction offers the opposite: the portrayal of a setting that completely disagrees with the author's ethos. Some novels combine both genres, often as a metaphor for the different directions humanity can take depending on its choices, ending up with one of two possible futures. Both utopias and dystopias are commonly found in science fiction and other types of speculative fiction.

Anno Domini 2000, or, Woman's Destiny (1889) is often referred to as New Zealand's first science fiction novel. It was written by former Prime Minister of New Zealand Sir Julius Vogel while he was in England. It anticipated a utopian world where women held many positions of authority, and in fact New Zealand became the first country to give women the vote, and from 1998 to 2008 continuously had a female Prime Minister, while for a short period (2005–2006) all five highest government positions were simultaneously held by women.
Artificial intelligence is a recurrent theme in science fiction, whether utopian, emphasising the potential benefits, or dystopian, emphasising the dangers.
A dystopia, also called a cacotopia or anti-utopia, is a community or society that is extremely bad or frightening. It is often treated as an antonym of utopia, a term that was coined by Sir Thomas More and figures as the title of his best known work, published in 1516, which created a blueprint for an ideal society with minimal crime, violence, and poverty. The relationship between utopia and dystopia is in actuality, not one simple opposition, as many utopian elements and components are found in dystopias as well, and vice versa.
In Marxist thought, a communist society or the communist system is the type of society and economic system postulated to emerge from technological advances in the productive forces, representing the ultimate goal of the political ideology of communism.

Utopian socialism is the term often used to describe the first current of modern socialism and socialist thought as exemplified by the work of Henri de Saint-Simon, Charles Fourier, Étienne Cabet, and Robert Owen. Utopian socialism is often described as the presentation of visions and outlines for imaginary or futuristic ideal societies, with positive ideals being the main reason for moving society in such a direction. Later socialists and critics of utopian socialism viewed utopian socialism as not being grounded in actual material conditions of existing society. These visions of ideal societies competed with revolutionary and social democratic movements.
