Materials Science In Science Fiction
Material science in science fiction is the study of how materials science is portrayed in works of science fiction. The accuracy of the materials science portrayed spans a wide range – sometimes it is an extrapolation of existing technology, sometimes it is a physically realistic portrayal of a far-out technology, and sometimes it is simply a plot device that looks scientific, but has no basis in science. Examples are:
- Realistic case: In 1944, the science fiction story "Deadline" by Cleve Cartmill depicted the atomic bomb. The properties of various radioactive isotopes are critical to the proposed device, and the plot. This technology was real, unknown to the author.
- Extrapolation: In The Fountains of Paradise, Arthur C. Clarke wrote about space elevators, basically a long cable extending from the Earth's surface to geosynchronous orbit. This requires a material with enormous tensile strength and light weight. Carbon nanotubes are strong enough in theory, so the idea is plausible; while one cannot be built today, it violates no physical principles.
- Plot device: An example of an unsupported plot device is scrith, the material used to construct Ringworld, in the novels by Larry Niven. Scrith possesses unreasonable strength, and is unsupported by physics as it is known, but needed for the plot.
Critical analysis of materials science in science fiction falls into the same general categories. The predictive aspects are emphasised, for example, in the motto of the Georgia Tech's department of materials science and engineering – Materials scientists lead the way in turning yesterday's science fiction into tomorrow's reality. This is also the theme of many technical articles, such as Material By Design: Future Science or Science Fiction?, found in IEEE Spectrum, the flagship magazine of Institute of Electrical and Electronics Engineers.
On the other hand, there is criticism of the unrealistic materials science used in science fiction. In the professional material science journal JOM, for example, there are articles such as The (Mostly Improbable) Materials Science and Engineering of the Star Wars Universe and Personification: The Materials Science and Engineering of Humanoid Robots.

Famous quotes containing the words materials, science and/or fiction:
“In how few words, for instance, the Greeks would have told the story of Abelard and Heloise, making but a sentence of our classical dictionary.... We moderns, on the other hand, collect only the raw materials of biography and history, “memoirs to serve for a history,” which is but materials to serve for a mythology.”
—Henry David Thoreau (1817–1862)
“Art is the beautiful way of doing things. Science is the effective way of doing things. Business is the economic way of doing things.”
—Elbert Hubbard (1856–1915)
“Americans will listen, but they do not care to read. War and Peace must wait for the leisure of retirement, which never really comes: meanwhile it helps to furnish the living room. Blockbusting fiction is bought as furniture. Unread, it maintains its value. Read, it looks like money wasted. Cunningly, Americans know that books contain a person, and they want the person, not the book.”
—Anthony Burgess (b. 1917)
