Revision history of "Henrietta Swan Leavitt"

This is a list of past revisions of Henrietta Swan Leavitt. 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.

(→ the paper is signed Pickering and written by Leavitt and both of those are on the page. not a theft and not nothing. the relation is called Leavitt's Law now, which is a correction made a hundred years late by nobody in particular)
• cur | prev 2016 ObscuriBot (talk | contribs) . . (1,740 bytes) (−55) m . . (→ reverted: the women at this observatory were not forbidden the telescopes, and Cannon observed from the beginning. Leavitt measured plates because measuring plates was the post. the rest of the objection stands and is answered in the article)
• cur | prev 2015 MudGeometer_1844 (talk | contribs) . . (1,795 bytes) (+55) . . (SHE NEVER LOOKD THROUGH THE TELESCOPE ONCE. THEY WOULD NOT LET HER. AND YOU ARE TELLING ME SHE MEASURED THE WHOLE UNIVERSE FROM A PEICE OF GLASS)
• cur | prev 1925 an editor (talk | contribs) . . (1,740 bytes) (+180) . . (→ Hubble has found Cepheids in the Andromeda nebula and applied her relation. the answer is too far away to be in our galaxy, so it is not a nebula and there is more than one galaxy. that follows from a line drawn through twenty-five points)
• cur | prev 1925 an editor (talk | contribs) . . (1,560 bytes) (+200) . . (→ Mittag-Leffler has written from Stockholm proposing to nominate her for the physics prize, and addressed the letter to her. Shapley answered it. he told him she died four years ago and that the decisive part of the work had been his own. the prize is not given posthumously and both halves of that reply are on the record)
• cur | prev 1921 an editor (talk | contribs) . . (1,360 bytes) (+140) . . (→ made head of stellar photometry this year and dead by December, of cancer, at fifty-three)
• cur | prev 1913 an editor (talk | contribs) . . (1,220 bytes) (+160) . . (→ Hertzsprung has fixed the scale. not by parallax to the nearer Cepheids, there being none near enough to show one, but from the proper motions of thirteen of them, with the Sun's own travel through space serving as the baseline. her ranking is now a ruler with numbers on it)
• cur | prev 1912 E. Pickering (talk | contribs) . . (1,060 bytes) (+120) m . . (→ issued as Circular 173 over my signature, which is the practice of this observatory. the first sentence says the work has been prepared by Miss Leavitt, which is also the practice, and in this instance is the more important line of the two)
• cur | prev 1912 H. Leavitt (talk | contribs) . . (940 bytes) (+380) . . (→ twenty-five of them in the Small Cloud. plotted against the period the points make a curve; plotted against the logarithm of the period they make a straight line. the Cloud is what does it. they are probably at nearly the same distance from us, so what looks brighter apparently is brighter. I have written it in those words and I mean them)
• cur | prev 1908 H. Leavitt (talk | contribs) . . (560 bytes) (+300) . . (→ one thousand seven hundred and seventy-seven variables in the Clouds, catalogued. I note near the end that the brighter of them have the longer periods, and I go no further with it. there are seventeen periods here and that is not enough to draw a conclusion from)
• cur | prev 1902 E. Pickering (talk | contribs) . . (260 bytes) (+260) . . (created page; Miss Leavitt is engaged to measure variables on the Magellanic plates. the work is exacting and the rate is thirty cents, and I am aware that those two facts are related to one another and to her sex)

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.
