In physics , the special theory of relativity , or special relativity for short, is a scientific theory regarding the relationship between space and time. In Albert Einstein 's original treatment, the theory is based on two postulates : [1] [2].

Time Dilation and Length Contraction

The length of any object in a moving frame will appear foreshortened in the direction of motion, or contracted. The amount of contraction can be calculated from the Lorentz transformation. The length is maximum in the frame in which the object is at rest. A clock in a moving frame will be seen to be running slow, or "dilated" according to the Lorentz transformation. The time will always be shortest as measured in its rest frame. The time measured in the frame in which the clock is at rest is called the "proper time".

The net result is a distorted view. Amazingly, for an object that subtends a small solid angle, the Terrell effect will cancel out the Lorentz contraction, making the object appear to have been rotated. Indeed, it allows you to see partly around the object and observe its reverse side. Of course, the rapidly moving Enterprise would also be subject to the Doppler effect, which would render it a different colour. Indeed, the frequency shift might even make the craft totally invisible to human eyes.

Time and the Metaphysics of Relativity pp Cite as. The relativity of simultaneity and the relativity of length lead naturally to the strangest consequences of relativity theory: time dilation and length contraction. Time dilation means that relative to a clock taken to be at rest, a moving clock runs slow, so that relative to the moving clock the amount of time recorded by the clock at rest expands or dilates. Let us suppose that we have two clocks A and B in motion relative to each other Figure 3. Unable to display preview. Download preview PDF.

Classical physics solves the problem by stating that the time interval has an absolute character being the same for all inertial observers in relative motion. Forced.

Length Contraction

People might describe distances differently, but at relativistic speeds, the distances really are different. Have you ever driven on a road that seems like it goes on forever? If you look ahead, you might say you have about 10 km left to go. If you both measured the road, however, you would agree. Traveling at everyday speeds, the distance you both measure would be the same.

Числа были огромными, в ряде случаев не совпадали единицы измерения. - Это все равно что вычитать апельсины из яблок, - сказал Джабба.  - Гамма-лучи против электромагнитной пульсации.

We apologize for the inconvenience...

 Примите мои поздравления, мистер Беккер. Мне сказали, что вы сегодня отличились. Вы позволите поговорить с вами об. Беккер заколебался. - Видите ли, я, честно говоря, очень спешу.  - Он надеялся, что отказ представителю самого мощного разведывательного ведомства не слишком большая глупость с его стороны, но партия в сквош начиналась через сорок пять минут, а он дорожил своей репутацией: Дэвид Беккер никогда не опаздывает на партию в сквош… на лекцию - да, возможно, но на сквош - .

Я бы хотел задержаться. - Значит, вы видели башню. Гиральду. Беккер кивнул.

are used to demonstrate graphically length contraction, time. dilation and other special relativistic effects in problems that. involve two frames.

Length Contraction

 - Слова лились потоком, словно ждали много лет, чтобы сорваться с его губ.  - Я люблю. Я люблю. В этот момент в тридцати метрах от них, как бы отвергая мерзкие признания Стратмора, ТРАНСТЕКСТ издал дикий, душераздирающий вопль. Звук был совершенно новым - глубинным, зловещим, нарастающим, похожим на змею, выползающую из бездонной шахты. Похоже, фреон не достиг нижней части корпуса. Коммандер отпустил Сьюзан и повернулся к своему детищу стоимостью два миллиарда долларов.

Note that time dilation and length contraction are just special cases: it is time-​dilation if ∆x = 0 and length contraction if ∆t = 0. 3. The spacetime interval (∆s)2​.
