Revision history of "Surveying"

This is a list of past revisions of Surveying. 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 2026 a county surveyor (talk | contribs) . . (3,510 bytes) (+130) . . (→ it is in the table on page four. it has been in the table on page four since before i was articled) (current)
• cur | prev 2026 NotTheMudGeometer (talk | contribs) . . (3,380 bytes) (+70) . . (→ BALANCING THE SIGHTS. SO THEY KNOW IT IS THERE AND THEY HIDE IT. THATS WORSE)
• cur | prev 2016 T. Vogel (talk | contribs) . . (3,310 bytes) (+280) . . (→ he has put the objection better than the article had, so the article now answers it. the plane is a tolerance and the tolerance has a number, and in levelling, where the curve would ruin the work, it is not neglected at all but cancelled by balancing the sights. removing an effect is not the same as denying it)
• cur | prev 2016 MudGeometer_1844 (talk | contribs) . . (3,030 bytes) (+80) . . (IF THE ERTH IS ROUND WHY DO THEY TEACH PLANE SURVEYING. I REST MY CASE AND I WANT IT IN THE FIRST LINE)
• cur | prev 1983 an editor (talk | contribs) . . (2,950 bytes) (+320) . . (→ satellites. the receiver works on a spheroid whether the man holding it knows or not, and the flat plan he hands the builder is a projection made afterwards, with the distortions chosen and written in the corner)
• cur | prev 1941 an editor (talk | contribs) . . (2,630 bytes) (−180) . . (→ the great theodolite was destroyed at Southampton in the raids. it had measured the country twice over and it read to a second, and there is nothing to be done about it now)
• cur | prev 1899 a county surveyor (talk | contribs) . . (2,810 bytes) (+260) . . (→ setting down the plain figure for the textbook: a hundred square miles and under, the plane will serve. over it, the spheroid. i am told this is a controversial sentence somewhere and i cannot think where)
• cur | prev 1870 A. R. Wallace (talk | contribs) . . (2,550 bytes) (+300) . . (→ sighted the Bedford Level at three heights rather than two, which is the whole of the method and the whole of the difference. i was paid and then i was sued and then i was hounded for twenty years, and the marks are where i said)
• cur | prev 1864 the Mud Geometer (talk | contribs) . . (2,250 bytes) (+90) . . (THEY WORK ON A FLAT PLANE. I HAVE WATCHED THEM DO IT ALL DAY AND NOT ONE OF THEM CURVED ANYTHING)
• cur | prev 1838 an editor (talk | contribs) . . (2,160 bytes) (+200) . . (→ adding the compass rule for closing a traverse, which the trade puts to Bowditch. the misclose is not hidden and not thrown away; it is spread along the legs in proportion, which is an admission written into the arithmetic)
• cur | prev 1821 C. F. Gauss (talk | contribs) . . (1,960 bytes) (+340) . . (→ taking the survey of Hanover, and obliged to invent an instrument to flash the sun from one station to the next before the stations could be seen at all. the observations will outnumber the unknowns on purpose, so that they may contradict one another and be made to say by how much. a measurement that cannot disagree with itself has told you nothing)
• cur | prev 1790 an editor (talk | contribs) . . (1,620 bytes) (+120) . . (→ Roy has died this year. the paper is in the volume and he is not in it)
• cur | prev 1790 W. Roy (talk | contribs) . . (1,500 bytes) (+400) . . (→ the operation from Greenwich to Paris is reduced and the account is with the Transactions, with the plate of the instrument. it remains to say what the numbers cost, which was five summers and most of my health)
• cur | prev 1787 J. Ramsden (talk | contribs) . . (1,100 bytes) (+420) . . (→ the instrument is finished. three feet across, two hundred pounds, and it will read a second of arc. the Society has waited three years and would have waited longer had i thought of anything else to improve)
• cur | prev 1617 W. Snell (talk | contribs) . . (680 bytes) (+380) . . (→ the distance from Alkmaar to Bergen op Zoom, by a chain of triangles and no chain on the ground. one measured base and the rest is angles. i commend the method and not the weather)
• cur | prev c. 1400 BC a rope-stretcher (talk | contribs) . . (300 bytes) (+300) . . (created page; the river has taken the boundaries again and we set them out again, by cord and by peg, as we do every year. the field is the same size whatever the water thinks)

Older revisions exist but have not been located. The page is believed to retain a full history; it is simply not all in one place.
