    The Ehrenfest paradox concerns the rotation of a "rigid" disc in the theory of relativity.. In its original 1909 formulation as presented by Paul Ehrenfest in relation to the concept of Born rigidity within special relativity, [1] it discusses an ideally rigid cylinder that is made to rotate about its axis of symmetry. [2] The radius R as seen in the laboratory frame is always perpendicular to ...

    Aug 31, 2023Or just stick to .dsk files which are a bit more authentic to the experience of using a Tatung Einstein. Two Tatung Einstein disk drives are supported. The default drive 0: is a standard single-sided, 40 track, 10 sector-per-track diskette with about 190K disk space available. This is the drive that will hold and load your .dsk file image when ...

    In a very interesting article entitled 'Einstein and the Rigidly Rotating Disk', has traced the 0genesis of the general theory of relativity based on the concept of a curved spacetime.As he remarks, the rigidly rotating disk' seems to provide a "missing link" in the chain of reasoning that led him (Einstein) to the crucial idea that a nonflat metric was needed for a relativistic ...

  6. Einstein's 1916 paper on GR makes no mention of elevators; instead, the Equivalence Principle is introduced via the rotating disk. Einstein reproduces Ehrenfest's argument, but with a different conclusion: since we are no longer assuming flat Minkowski space, Einstein asserts that geometry for the rigid rotating disk is noneuclidean.

    In a recent paper we presented analytic expressions for the axis potential, the disk metric, and the surface mass density of the global solution to Einstein's field equations describing a rigidly rotating disk of dust. Here we add the complete solution in terms of ultraelliptic functions and quadratures.
  8. Einstein's first mention of the uniformly rotating disk in print was in 1912, in his paper dealing with the static gravitational fields. After the 1912 paper, the rotating disk problem occurred in Einstein's writings only in a 1916 review paper, "The Foundation of the General Theory of Relativity". Einstein did not mention the rotating disk problem in any of his papers on gravitation theory ...
  9. Introduction to Einstein's famous rotating disk thought experiment, which he used to help him understand the true nature of gravity. Learning Outcomes: • Understanding that an observer placed at the edge of a rotating disk (or inside a rotating cylinder) experiences an artificial gravitational field related to his centripetal acceleration. ...

    The 3" disk drives used in the Einstein were unique and especially made of the machine, but I am led to believe somewhat similar to the 3" drives for the Amstrad (I think the power inputs were swapped though) hence the CPC disk software is used when writing images back to original disks.
