A major theme of science fiction and of speculative biology is to convey a message of optimism or pessimism according to the author's worldview. [5] [6] Whereas optimistic visions of technological progress are common enough in hard science fiction, pessimistic views of the future of humanity are far more usual in fiction based on biology. [4]
A rendering of the magnetic field lines of the magnetosphere of the Earth. In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. [1] [2] It is created by a celestial body with an active interior dynamo.
Organ transplantation is a common theme in science fiction and horror fiction, appearing as early as 1925, in Russian short story Professor Dowell's Head. [1] It may be used as a device to examine identity, power and loss of power, [2] current medical systems; explore themes of bodily autonomy; or simply as a vehicle for body horror or other fantastical plots.
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 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.
Spherical harmonics can represent any scalar field (function of position) that satisfies certain properties. A magnetic field is a vector field, but if it is expressed in Cartesian components X, Y, Z, each component is the derivative of the same scalar function called the magnetic potential. Analyses of the Earth's magnetic field use a modified ...
"Travel by Wire!" is a science fiction short story by English writer Arthur C. Clarke. His first published story, it was first published in December 1937 .This story is a humorous record on the development of the "radio-transporter" (actually a teleportation machine), and the various technical difficulties and commercial ventures that resulted.
The plasmasphere, or inner magnetosphere, is a region of the Earth's magnetosphere consisting of low-energy (cool) plasma. It is located above the ionosphere . The outer boundary of the plasmasphere is known as the plasmapause , which is defined by an order of magnitude drop in plasma density.
