The Currents of Space is a science fiction novel by the American writer Isaac Asimov, published in 1952. It is the second (by internal series chronology) of three books labeled the Galactic Empire series , but it was the last of the three to be written.
The three Empire books, first published between 1950 and 1952, are Asimov's three earliest novels published in his own name (David Starr, Space Ranger was published before The Currents of Space, but had been published under his pen name "Paul French", and the Foundation books were collections of linked short stories rather than continuous novels).
The Currents of Space The Stars, Like Dust was serialized in Galaxy Science Fiction as Tyrann in early 1951, and issued in book form around the same time. The Stars, Like Dust is a 1951 science fiction mystery book by American writer Isaac Asimov .
Auroral Birkeland currents are constrained along the geomagnetic field. Therefore, the current’s distribution in 3-dimensional space could be largely described using the 2-dimensional distribution of the current’s footprints at a given altitude in the ionosphere, e.g., 110 km.
The term outward space existed in a poem from 1842 by the English poet Lady Emmeline Stuart-Wortley called "The Maiden of Moscow", [13] but in astronomy the term outer space found its application for the first time in 1845 by Alexander von Humboldt. [14] The term was eventually popularized through the writings of H. G. Wells after 1901. [15]
Geomagnetically induced currents (GIC) are electrical currents induced at the Earth's surface by rapid changes in the geomagnetic field caused by space weather events. GICs can affect the normal operation of long electrical conductor systems such as electric transmission grids and buried pipelines.
In the differential form formulation on arbitrary space times, F = 1 / 2 F αβ dx α ∧ dx β is the electromagnetic tensor considered as a 2-form, A = A α dx α is the potential 1-form, = is the current 3-form, d is the exterior derivative, and is the Hodge star on forms defined (up to its orientation, i.e. its sign) by the ...
The heliospheric current sheet, or interplanetary current sheet, is a surface separating regions of the heliosphere where the interplanetary magnetic field points toward and away from the Sun. [1] A small electrical current with a current density of about 10 −10 A /m 2 flows within this surface, forming a current sheet confined to this surface.
