Physics has aseendedto summits hitherto visible only to phitosophers,whose gazehas, however, not always been free from metaphysiealhaziness.
Albert Einstein is the guide who has directed. Employrng an astoundingly ingenious analysis,he has purged. The faet that the refinement of the sonceptions, by a critical examination of them from the viewpoint of the theory of knowledge, is simultaneously combined with the physical application which immediately made his ideas experimentally verifiable, is perhaps the most noteworthy feature of his achievement: The unrivalled aehievementsin research, which in past centuries have enriched our knowledge of physical nature, Ieft these underrying conceptions untouched until the year LgOb.
The efforts of physieists had always been directed. Time were regarded, so to speak, as vesselseontaining this substratum and furnishing fixed systems of referenee, with the help of which the mutual relations betweenbodies and eventshad to be determined: From the standpoint of the theory of knowledge,the objection was quite early raised against Newton, that there was no meaning in the terms Spaceand Time as usedwithout 'refereneeto an objeet'; but, for the time being,physies had.
Lorentz and Fitzgerald, that every body which is in motion relatively to the aether is subjectto a definite contraction along the direction of motion the soaalled Lorcntz-contractionwhich dependsupon the veloeity of the body.
This hypothesis was set up in order to er- 3 From Newton to Ei'nstein plain why it seemedimpossible to detect 'absolute' reotilinear motion of our instruments by means of the experiment of Michelson and Morley which will be discussedbelow ' whereas,accord.
The whole trend of physical d. For Einstein recoguized that there is a much simpler way of explainins from first principles the negative result of Miehelson and Morley's experiment.
No special physical hypothesis at all is required. It is only necessary to recognize lhe principle of 'absurelativity, according to which a rectilinear uniform lute'motion can never be detected,and the f.
Ile saw also that a critical examination of the assumptions upon which our space- and time-measurementshave hitherto been tacitly founded is necessary. Amongst these unnecessary and.
If these assumptions are dropped, the result of Michelson and Morley's experiment appears self-evident, and on the ground thus cleared. The special principle of relativity intleetl takes one eonsiderably beyond the Newtonian conceptionsof Space and 4 Franb Newton to Einstein Time as wilt be seen from the short account in the next chapterbut does not fully satisfy the philosophiomind, inasmuchas this restricted theory is only valid for uniform rectilinear motions.
From the philosophic standpoint it is desirable to be able to affirm that eaery motion is relative, i. According to the special theory, irregular motions would.
Theseendeavourswerebrought to a happy conclusion in ,being crow: They led to such an extreme degree of relativization of all spaee-and time-determinationsthat it seemsimpossibleto extend it any further; these space- and" time-determinations will henceforth be inseparably connectedwith matter, and will have meaning only when referred to it.

A modern self-contained introduction to key topics in advanced general relativity. The opening chapter reviews the subject, with strong emphasis on the geometric structures underlying the theory.
