Formulate conclusions of the theory of special relativity, noting the assumptions that were made in deriving it. According to the theory of special relativity, it is impossible to say in an absolute sense whether two distinct events occur at the same time if those events are separated in space, such as a car crash in London and another in New York.
In Minkowski-Space the space-time of special relativity is discussed on the basis of fundamental results of space-time theory. This idea has the consequence that the Minkowski-space can be characterized by 5 axioms, which determine its geometrical and kinematical structure completely. In this sense Minkowski-Space is a prolegomenon for the formulation of other branches of special relativity, like mechanics, electrodynamics, thermodynamics etc. But these applications are not subjects of this book.

What is relativity? Einstein's mind-bending theory explained
In physics , spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold. The fabric of space-time is a conceptual model combining the three dimensions of space with the fourth dimension of time. Spacetime diagrams can be used to visualize relativistic effects, such as why different observers perceive differently where and when events occur. Until the 20th century, it was assumed that the three-dimensional geometry of the universe its spatial expression in terms of coordinates, distances, and directions was independent of one-dimensional time. The famous physicist Albert Einstein helped develop the idea of space-time as part of his theory of relativity.
Einstein's Theory of Special Relativity
In physics and relativity , time dilation is the difference in the elapsed time as measured by two clocks. It is either due to a relative velocity between them "kinetic" time dilation, from special relativity or to a difference in gravitational potential between their locations gravitational time dilation , from general relativity. When unspecified, "time dilation" usually refers to the effect due to velocity. After compensating for varying signal delays due to the changing distance between an observer and a moving clock i.
The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. One of its most famous aspects concerns objects moving at the speed of light. Simply put, as an object approaches the speed of light, its mass becomes infinite and it is unable to go any faster than light travels.
Special relativity changed the way we view space and time and showed us that time is relative to an observer. Formulate major changes in the understanding of time, space, mass, and energy that were introduced by the theory of Special Relativity. The theory of Special Relativity and its implications spurred a paradigm shift in our understanding of the nature of the universe, the fundamental fabric of which being space and time. Before , scientists considered space and time as completely independent objects. Time could not affect space and space could not affect time.
Einstein's Space-Time: An Introduction to Special and General Relativity is a textbook addressed to students in physics and other people interested in Relativity and a history of physics. The first chapters are aimed to afford a deep understanding of the relativistic spacetime and its consequences for Dynamics. It is a remarkable resource for intermediate and advanced undergraduates, as it introduces the more difficult mathematics with a minimum of formalism. Lower-division undergraduates through faculty. The style of the book is fresh and the author, paying attention to details, tries also to explain the material in his own words ….
relativity appears to be that of specifying the properties of space and time, the arena in which all physical processes take place. It is perhaps a little unfortunate.
Implications of Special Relativity
When the theory of relativity appeared in the early s, it upended centuries of science and gave physicists a new understanding of space and time. Isaac Newton saw space and time as fixed, but in the new picture provided by special relativity and general relativity they were fluid and malleable. Albert Einstein. He published the first part of his theory — special relativity — in the German physics journal Annalen der Physik in and completed his theory of general relativity only after another decade of difficult work. He presented the latter theory in a series of lectures in Berlin in late and published in the Annalen in
The experimental testing of the Lorentz transformations is based on a family of sets of coordinate transformations that do not comply in general with the principle of equivalence of the inertial frames. The Lorentz and Galilean sets of transformations are the only member sets of the family that satisfy this principle. In the neighborhood of regular points of space-time, all members in the family are assumed to comply with local homogeneity of space-time and isotropy of space in at least one free-falling elevator, to be denoted as Robertson's ab initio rest frame [H. Robertson, Rev. Without any further assumptions, it is shown that Robertson's rest frame becomes a preferred frame for all member sets of the Robertson family except for, again, Galilean and Einstein's relativities. If one now assumes the validity of Maxwell-Lorentz electrodynamics in the preferred frame, a different electrodynamics spontaneously emerges for each set of transformations. The flat space-time of relativity retains its relevance, which permits an obvious generalization, in a Robertson context, of Dirac's theory of the electron and Einstein's gravitation.

Она взглянула на скоростное печатное устройство позади письменного стола шефа. В нем ничего не. - Сьюзан, - тихо сказал Стратмор, - с этим сначала будет трудно свыкнуться, но все же послушай меня хоть минутку.
Офицер еще какое-то время разглядывал паспорт, потом положил его поверх вороха одежды. - У этого парня была виза третьего класса. По ней он мог жить здесь многие годы. Беккер дотронулся до руки погибшего авторучкой.
А вместо этого он заразил вирусом главный банк данных Агентства национальной безопасности. И этот вирус уже невозможно остановить - разве что вырубить электроэнергию и тем самым стереть миллиарды бит ценнейшей информации.
Все вокруг недоуменно переглянулись. Соши лихорадочно прогоняла текст на мониторе в обратном направлений и наконец нашла то, что искала. - Да. Здесь говорится о другом изотопе урана. Мидж изумленно всплеснула руками.
Шифруя послание, Сьюзан просто заменила в нем каждую букву на предшествующую ей алфавите.
Потные ладони скользили по гладкой поверхности. Он вытер их о брюки и попробовал. На этот раз створки двери чуть-чуть разошлись. Сьюзан, увидев, что дело пошло, попыталась помочь Стратмору. Дверь приоткрылась на несколько сантиметров.
- Наверное, увидел включенный монитор.
