Mind uploading—transferring an individual's personality to a computer—appears in several works of fiction. [1] It is distinct from the concept of transferring a consciousness from one human body to another. [2] [3] It is sometimes applied to a single person and other times to an entire society. [4]
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 ".
Sublimation is a technique used by chemists to purify compounds. A solid is typically placed in a sublimation apparatus and heated under vacuum . Under this reduced pressure , the solid volatilizes and condenses as a purified compound on a cooled surface ( cold finger ), leaving a non-volatile residue of impurities behind.
Sigmund Freud, 1926. In psychology, sublimation is a mature type of defense mechanism, in which socially unacceptable impulses or idealizations are transformed into socially acceptable actions or behavior, possibly resulting in a long-term conversion of the initial impulse.
A sublimatory [1] [2] or sublimation apparatus is equipment, commonly laboratory glassware, for purification of compounds by selective sublimation. In principle, the operation resembles purification by distillation , except that the products do not pass through a liquid phase .
The sublime has also been described as a key to understanding the sense of wonder concept in science fiction literature, [14] and in connection with Kenneth Burke's rhetorical aesthetic theory of form. [15] In early modernist discourse, the urban landscape became an important subject of the sublime.
Examples of this type of depiction include the hologram of Princess Leia in Star Wars, Arnold Rimmer from Red Dwarf, who was later converted to "hard light" to make him solid, and the Holodeck and Emergency Medical Hologram from Star Trek. [1] Holography served as an inspiration for many video games with the science fiction elements.
Sublimation is the process of changing of any substance (usually on heating) from a solid to a gas (or from gas to a solid) without passing through liquid phase. In terms of purification - material is heated, often under vacuum, and the vapors of the material are then condensed back to a solid on a cooler surface.
