...interesting passage in Einstein's Theory of Relativity. " We entirely shun," he says, " the vague word space, of which, we must honestly acknowledge, we cannot...relative to a practically rigid body of reference." 2 It is difficult to appreciate the exact value of this statement, because it is not strictly adhered...

...meant by motion in space t " he asks. " In the first place, we entirely shun the vague word ' space ', of which we must honestly acknowledge we cannot form...relative to a practically rigid body of reference." Again, we are told to " free ourselves from this fatal error ", and speak only of " bodies of reference...

...motion in space, and this is his answer: ' We entirely shun the vague word space, of which we must ' acknowledge we cannot form the slightest conception, and ' we replace it by motion relative to a rigid body of reference.' He takes as an example the motion of a stone thrown out of the window as...

...geometrical properties of the material bodies. Einstein writes:1 "We entirely shun the vague word 'space,' of which we must honestly acknowledge we cannot form...relative to a practically rigid body of reference.' " This difficulty may be removed by supposing that space is not empty, but filled with a medium, the...

...marks on a rigid body. . . . [Now, with regard to the train,] we entirely shun the vague word "space," of which, we must honestly acknowledge, we cannot...relative to a practically rigid body of reference." (8) There is no causal connecting principle in Proust's world. A stereoscopic vision is evident in...

...is meant here by motion "in space"? ... In the first place we entirely shun the vague word "space," of which, we must honestly acknowledge, we cannot...relative to a practically rigid body of reference." ... If instead of "body of reference" we insert "system of co-ordinates," which is a useful idea for...

...physical world. According to Einstein: "In the first place we entirely shun the vague word 'space,' of which, we must honestly acknowledge, we cannot...relative to a practically rigid body of reference.' " 106 From this premise, the nature of space undergoes transformation. 107 It is well known that Einstein's...

...absolute space has no meaning. In 1916 Einstein explained: "We entirely shun the vague word 'space/ of which, we must honestly acknowledge, we cannot...relative to a practically rigid body of reference.' "" With the general theory of relativity the number of spaces increased beyond calculation to equal...

...1961:9) Einstein goes on to argue that we cannot make much sense of the idea of motion 'in space' unless we replace it by 'motion relative to a practically rigid body of reference'. If we then replace 'body of reference' by 'system of coordinates', we are in a position to say: The...

...only to clarify the details. (Page 9) "In the first place we entirely shun the vague word 'space', of which, we must honestly acknowledge, we cannot form the slightest conception". Oh well. (Page 55) "Space is a three dimensional continuum. By this we mean that it is possible to...
