Revision history of "The Sagnac effect"

This is a list of past revisions of The Sagnac effect. Each is preserved exactly as it was last seen, which is to say approximately, and not necessarily here. Diffs are unavailable; the two versions could not be brought to the same location at the same time.

• cur | prev June 2018 T. Vogel (talk | contribs) . . (1,890 bytes) (+300) . . (→ In this encyclopedia: the effect offered as the disproof of relativity is a photograph of the one part of relativity these gentlemen most dislike. the instrument is not aware of the argument and reports the rotation regardless)
• cur | prev 2014 a relativist (talk | contribs) . . (1,590 bytes) (+90) . . (→ and the general case comes out of the rotating metric without amendment. Mr Wang has measured the formula that was already written down)
• cur | prev 2003 an editor (talk | contribs) . . (1,500 bytes) (+150) . . (→ The generalised effect: the published result is that it is not only rotation. a straight length of fibre moving on a belt gives the same shift, proportional to its velocity. the integral was never about rotation)
• cur | prev 1993 a geodesist (talk | contribs) . . (1,350 bytes) (+90) . . (→ one of them is bolted to bedrock in Bavaria and reads the length of the day. it also reads the pole wobbling, which we did not ask it to do)
• cur | prev 1963 an engineer (talk | contribs) . . (1,260 bytes) (+110) . . (→ Ring lasers: these are going into aircraft. they are sold as rotation sensors, on the grounds that rotation is what they sense)
• cur | prev 1926 an editor (talk | contribs) . . (1,150 bytes) (+70) . . (rv the Concord; it found rotation and did not find translation. those are two words and the difference between them is the whole page)
• cur | prev 1925 the Concord (talk | contribs) . . (1,080 bytes) (−70) . . (→ struck the conclusion. the apparatus has found a motion. we have said for seventy years that it would find a motion ~~~~)
• cur | prev 1925 A. Michelson (talk | contribs) . . (1,150 bytes) (+280) . . (→ Michelson, twice: 610 by 340 metres at Clearing, Illinois, pumped out. predicted 0.236 of a fringe and observed 0.230. I have now measured the Earth twice, once by finding nothing and once by finding this)
• cur | prev 1923 A. Michelson (talk | contribs) . . (870 bytes) (+80) . . (→ a trial at Mount Wilson. the air inside the pipe ruins the fringes. the pipe must therefore be emptied, which alters the cost of the thing considerably)
• cur | prev 1916 an editor (talk | contribs) . . (790 bytes) (+60) . . (→ note that the table was turning. this will matter later and it is not being noted for the pleasure of noting it)
• cur | prev 1913 the Concord (talk | contribs) . . (730 bytes) (+90) . . (→ adopted with thanks. M. Sagnac has caught the aether on a turning table, which is where we should have thought to look ~~~~)
• cur | prev 1913 G. Sagnac (talk | contribs) . . (640 bytes) (+340) . . (→ built one. the fringes move when the table turns, and they move by the amount the enclosed area requires. I take this to demonstrate the medium)
• cur | prev 1904 A. Michelson (talk | contribs) . . (300 bytes) (+300) . . (created; a plan for testing the effect of the Earth's rotation upon the velocity of light. I have not built it and have no present intention of building it)
