Koestler's Kepler in History of Science subsection

I am surprised to see no reference to Arthur Koestler's "The Sleepwalkers" in the 'History of science' subsection of this article, but only in the 'Cultural influence and eponymy' subsection further down. Koestler made Kepler the central figure of his entire work, as the archetypal confluence of induction and reduction in the European Renaissance. For Koestler, in Kepler one sees an operator acting under the influence of both logical positivism and mystic inspiration, attributing them both with equal importance in his work. — Preceding unsigned comment added by 81.187.204.235 (talk) 09:05, 12 March 2023 (UTC)[reply]

Different calendars

As the German Wikipedia article on Kepler rightfully points out, his birth date is given in the Julian calendar, whereas the date of his death is given in the Gregorian calendar. The German article reads: “(* 27. Dezember 1571^jul. in Weil der Stadt; † 15. November 1630^greg. in Regensburg).”

I think we should do the same in the English version.

Thoughts?

Do we use that superscript style elsewhere on enwiki? Or are we more likely to use {{OldStyleDate}}? --jpgordon^{𝄢𝄆𝄐𝄇} 16:33, 29 April 2023 (UTC)[reply]

I’m thinking {{OldStyleDate}} as I don’t remember seeing that superscript annotation anywhere else on English Wikipedia. Another option would be a note, like there is for Isaac Newton.

Solar vs lunar eclipse

"Though the essay did not earn him a place in Ferdinand's court, it did detail a new method for measuring lunar eclipses, which he applied during the 10 July eclipse in Graz." The eclipse of 10 July 1600 was a solar eclipse, not a lunar eclipse, so either the method was for measuring solar eclipses or it would need some explanation how a method ment for measuring lunar eclipses can be used for a solar eclipse.

Kepler's equation

Kepler's equation should be mentioned in the text of the article. ReyHahn (talk) 10:36, 7 November 2024 (UTC)[reply]
