- Science fiction (sometimes shortened to sf or sci-fi) is a genre of speculative fiction, which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, and extraterrestrial life. Science fiction can trace its roots to ancient mythology. It is related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers.
- Speculative fiction (Wikipedia)
Speculative fiction (also known as the fantastic, and as fantastika in Slavic countries) is an umbrella genre of fiction that encompasses all the subgenres that depart from realism, or strictly imitating everyday reality, instead presenting fantastical, supernatural, futuristic, or other imaginative realms. This catch-all genre includes, but is not limited to, science fiction, fantasy, horror, slipstream, magical realism, superhero fiction, alternate history, utopia and dystopia, fairy tales, steampunk, cyberpunk, weird fiction, and some apocalyptic and post-apocalyptic fiction. The term has been used for works of literature, film, television, drama, video games, radio, and their hybrids.
- Science (Wikipedia)
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the world. Modern science is typically divided into two or three major branches: the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the behavioural sciences (e.g., economics, psychology, and sociology), which study individuals and societies. The formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems governed by axioms and rules, are sometimes described as being sciences as well; however, they are often regarded as a separate field because they rely on deductive reasoning instead of the scientific method or empirical evidence as their main methodology. Applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine.
- Technology (Wikipedia)
Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. The word technology can also mean the products resulting from such efforts, including both tangible tools such as utensils or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life.
