Questions raised by these scholars include asking to what degree Einstein was familiar with Poincaré's work, whether Einstein was familiar with Lorentz's 1904 paper or a review of it, and how closely Einstein followed other physicists at the time. It is known that Einstein was familiar with Poincaré's 1902 paper [Poi02], but it is not known ...
As recorded on the first page of Subtle Is the Lord, Pais' biography of Einstein, Pais responded to the effect of: 'The twentieth century physicist does not, of course, claim to have the definitive answer to this question.' [9] Pais' answer was representative not just of himself and of Bohr, but of the majority of quantum physicists of that ...
The timeless universe is the philosophical and ontological view that time and associated ideas are human illusions caused by our ordering of observable phenomena.Unlike most variants of presentism and eternalism, the timeless universe entirely rejects the notion of the reality of any time, arguing that it is exclusively a human illusion, and since the universe can know no time, no dimension of ...
Time is the continuous progression of existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. [1] [2] [3] It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or in the ...
The field equations of general relativity are not parameterized by time but formulated in terms of spacetime. Many of the issues related to the problem of time exist within general relativity. At the cosmic scale, general relativity shows a closed universe with no external time. These two very different roles of time are incompatible. [4]
Reference to the final form of the equations appears only in a footnote added to the paper, indicating that Einstein had not known the final form of the equations on 18 November. This is not controversial, and is consistent with the well-known fact that Einstein did not complete the field equations (with the trace term) until 25 November.
In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time.In Albert Einstein's 1905 paper, On the Electrodynamics of Moving Bodies, the theory is presented as being based on just two postulates: [p 1] [1] [2]
The earliest recorded philosophy of time was expounded by the ancient Egyptian thinker Ptahhotep (c. 2650–2600 BC) who said: . Follow your desire as long as you live, and do not perform more than is ordered, do not lessen the time of the following desire, for the wasting of time is an abomination to the spirit...
