The surface energy of a liquid may be measured by stretching a liquid membrane (which increases the surface area and hence the surface energy). In that case, in order to increase the surface area of a mass of liquid by an amount, δA, a quantity of work, γ δA, is needed (where γ is the surface energy density of the liquid).
Materials 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 ...
One of three stable transuranic elements predicted by the new science of nucleonics in James P. Hogan's Giants series. Not naturally occurring outside of neutron stars, but trace amounts are created at the detonation of nucleonic weapons. Bureaucratium Scientific in-joke: Similar to Administratium and variation of the joke.
A Sun scoop or sunscoop is a refueling technique for starships seen in science fiction. It involves a literal scooping of plasma directly from the outer surface of a star to use as fuel. Doing so would be extremely dangerous and only used in emergency situations.
Energy shield from the game Second Life. In speculative fiction, a force field, sometimes known as an energy shield, force shield, energy bubble, or deflector shield, is a barrier produced by something like energy, negative energy, dark energy, electromagnetic fields, gravitational fields, electric fields, quantum fields, telekinetic fields, plasma, particles, radiation, solid light, magic, or ...
Science in science fiction is the study or of how science is portrayed in works of science fiction, including novels, stories, and films. It covers a large range of topics. Hard science fiction is based on engineering or the "hard" sciences (for example, physics, astronomy, or chemistry).
The list includes technologies that were first posited in non-fiction works before their appearance in science fiction and subsequent invention, such as ion thruster. To avoid repetitions, the list excludes film adaptations of prior literature containing the same predictions, such as " The Minority Report ".
The Fowkes hypothesis (after F. M. Fowkes) is a first order approximation for surface energy.It states the surface energy is the sum of each component's forces: γ=γ d +γ p +γ i +... where γ d is the dispersion component, γ p is the polar, γ i is the dipole and so on.
