The principle of relativity. Unity of space and time. Inertial frames.
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.

Back Matter Pages About this book Introduction This volume is dedicated to the centennial anniversary of Minkowski's discovery of spacetime. It contains selected papers by physicists and philosophers on the Nature and Ontology of Spacetime.
The first six papers, comprising Part I of the book, provide examples of the impact of Minkowski's spacetime representation of special relativity on the twentieth century physics. Part II also contains six papers which deal with implications of Minkowski's ideas for the philosophy of space and time. The last part is represented by two papers which explore the influence of Minkowski's ideas beyond the philosophy of space and time.

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. This cosmic speed limit has been a subject of much discussion in physics, and even in science fiction, as people think about how to travel across vast distances. The theory of special relativity was developed by Albert Einstein in , and it forms part of the basis of modern physics. After finishing his work in special relativity, Einstein spent a decade pondering what would happen if one introduced acceleration.
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. The question of whether the events are simultaneous is relative: in some reference frames the two accidents may happen at the same time, in other frames in a different state of motion relative to the events the crash in London may occur first, and still in other frames, the New York crash may occur first. If we imagine one reference frame assigns precisely the same time to two events that are at different points in space, a reference frame that is moving relative to the first will generally assign different times to the two events. This is illustrated in the ladder paradox, a thought experiment which uses the example of a ladder moving at high speed through a garage.
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.
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.

Revised Robertson's test theory of special relativity: Space-time structure and dynamics
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.
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.
Трудно даже поверить, подумал Беккер, что после всех выпавших на его долю злоключений он вернулся туда, откуда начал поиски. Чего же он ждет. Он засмеялся. Ведь пилот может радировать Стратмору.
