Special relativity is defined in the absence of gravity, so for practical applications, it is a suitable model whenever gravity can be neglected.

Unlike most major shifts in scientific thought, special relativity was adopted by the scientific community remarkably quickly, consistent with Einstein's later comment that the laws of physics described by the Special Theory were " ripe for discovery " in 1905.

Special relativity shows that rest mass ( or invariant mass ) and rest energy are essentially equivalent, via the well-known relationship E = mc < sup > 2 </ sup >.

Special relativity explains the motion of objects with a high velocity, approaching the speed of light ; general relativity is employed to handle gravitation motion at a deeper level.

** Special relativity, a theory formulated by Albert Einstein, Henri Poincaré, and Hendrik Lorentz

Special relativity ( SR, also known as the special theory of relativity or STR ) is the physical theory of measurement in an inertial frame of reference proposed in 1905 by Albert Einstein ( after the considerable and independent contributions of Hendrik Lorentz, Henri Poincaré and others ) in the paper " On the Electrodynamics of Moving Bodies ".

Special relativity incorporates the principle that the speed of light is the same for all inertial observers regardless of the state of motion of the source.

Special relativity reveals that c is not just the velocity of a certain phenomenon — namely the propagation of electromagnetic radiation ( light )— but rather a fundamental feature of the way space and time are unified as spacetime.

Special relativity is a theory of the structure of spacetime.

Special relativity is based on two postulates which are contradictory in classical mechanics:

* Special relativity references

Special relativity does not claim that all observers are equivalent, only that all observers at rest in inertial reference frames are equivalent.

Special relativity suggests that the concept of simultaneity is not universal: according to the relativity of simultaneity, observers in different frames of reference can have different perceptions of whether a given pair of events happened at the same time or at different times, with there being no physical basis for preferring one frame's judgments over another's ( though in a case where one event A happens in the past light cone of another event B, all frames will agree that A happened in the past of B ).

Special and general relativity use spacetime rather than space ; spacetime is modeled as a four-dimensional space ( with the time axis being imaginary in special relativity and real in general relativity, and currently there are many theories which use more than four spatial dimensions.

Other movies, such as the Planet of the Apes series, explained their depictions of time travel by drawing on physics concepts such as the Special relativity phenomenon of time dilation ( which could occur if a spaceship was travelling near the speed of light ).

Although there are seven other types of annual awards presented by the Academy ( the Irving G. Thalberg Memorial Award, the Jean Hersholt Humanitarian Award, the Gordon E. Sawyer Award, the Scientific and Engineering Award, the Technical Achievement Award, the John A. Bonner Medal of Commendation, and the Student Academy Award ) plus two awards that are not presented annually ( the Special Achievement Award in the form of an Oscar statuette and the Honorary Award that may or may not be in the form of an Oscar statuette ), the best known one is the Academy Award of Merit more popularly known as the Oscar statuette.

The classic example, considered by their American counterparts quite curious, was the maintenance of the internal comma in a British organisation of secret agents called the " Special Operations, Executive " — " S. O., E " — which is not found in histories written after about 1960.

Ballochbuie is also protected as a Special Area of Conservation by the EU Habitats Directive, as " one of the largest remaining continuous areas of native Caledonian Forest ".

There is also a special 64-page book available, The Beano Special Collectors Edition: 70 Years of Fun, giving a brief history of the comic.

The Maroon beret is a symbol of the South African Special Forces Brigade and the South African 44 Parachute Regiment.

* In the movie Wag the Dog, the fictitious unit 303 Special Forces has a song created titled " The Men of the 303 " that is played to a deliberately similar but original tune written by Huey Lewis for the film.

* Ivan, one of the protagonists of the historical novel by the Cuban writer Leonardo Padura Fuentes, El hombre que amaba a los perros ( The Man Who Loved Dogs ), is the editor of a university journal of veterinary medicine, who manages to make a living during the Special Period in Cuba by helping people take care of their dogs.

Outside the Fuerza Pública, there is a small Special Forces Unit, the Unidad Especial de Intervencion ( UEI ) or Special Intervention Unit, which trains with special forces of Israel, and its namesake in Spain and other democratic nations, but is not part of the main police forces.

Agriculture is dealt with separately by the Special Committee on Agriculture ( SCA ).

Special variants called aircraft catapults are used to launch planes from land bases and sea carriers when the takeoff runway is too short for a powered takeoff or simply impractical to extend.

Usually it is considered to include several sub-departments: the Art Department proper, with its Art Director, Set Designers and Draughtsmen ; Set Decoration, under the Set Decorator ; Props, under the Propmaster ; Construction, headed by the Construction Coordinator ; Scenic, headed by the Key Scenic Artist ; and Special Effects.

It was announced, in September 2005, that the Metropolitan Police Special Branch would be merging with the Anti-Terrorism Branch of the Metropolitan Police to form a new department called Counter Terrorism Command, with the new department coming into being on 2 October 2006, thus completing a process begun when the investigative wing of the Special Branch X squad became The Anti-Terrorist Branch in 1972.

* Special ledger line handling: ledger lines are shortened when accidentals are nearby, thus enhancing readability.

Special overpacks are designed to help limit this field " in the field ," and thus allow such devices to be transported safely.

For a period there were thus two simultaneous land speed records, the 1947 Railton Mobil Special record remaining as the FIA four-wheel Class A record, which from July 1964 went to Campbell's Bluebird.

The fame thus bestowed upon Fleet Pond led, in 1951, to it becoming one of the first Sites of Special Scientific Interest to be notified in Hampshire.

Because of its use it remains untouched by modern intensive farming and is thus part of the last chalk grassland in the UK ( and probably Europe ) and the whole area is designated as an SSSI ( Site of Special Scientific Interest ).

In the end, he appointed a Lango to the post and attempted to counter the objection of Acholi officers by spying on them, reviving his old paramilitary counterweight, the mostly Langi Special Force Units, and thus repeating some of the actions that led to his overthrow by Amin.

The Joint Special Operations Agency thus did little to improve SOF readiness, capabilities, or policies, and therefore was insufficient.

Adolf Brand, founder of the first homosexual periodical, Der Eigene ( The Special ), had printed a pamphlet which described how Bülow had been blackmailed for his sexuality and had kissed and embraced Scheefer at male gatherings hosted by Eulenburg, and thus was morally obliged to publicly oppose Paragraph 175.

The. 44 Magnum is based on a lengthened. 44 Special case, loaded to higher pressures for greater velocity ( and thus, energy ).

The. 44 Magnum case is slightly longer than the. 44 Special case, not because of the need for more room for propellant, but to prevent the far higher pressure cartridge from being chambered in older, weaker. 44 Special firearms, thus preventing injuries and possible deaths.
