16:0516:05, 28 November 2023 diff hist +62‎ Qubit ‎ I clarified my additional edit. Fundamentally photons have spin, but this can be measured as linear polarization also depending on the detector. So, while qubit applications often use Horizontal and Vertical representation, it is important not to propagate a misconception about fundamental physics. This edit tried to thread that needle. Tag: 2017 wikitext editor
15:1615:16, 28 November 2023 diff hist +4‎ m Qubit ‎ I changed vertical and horizontal to left-handed and right-handed. This corrects the fundamental physics of photons. An individual photon has angular momentum, which results in circular polarization not linear polarization. Tag: 2017 wikitext editor

17:5917:59, 4 March 2021 diff hist +32‎ m Subrahmanyan Chandrasekhar ‎ →‎Personal life: Added link to College where he met his wife. Tag: 2017 wikitext editor
17:4917:49, 4 March 2021 diff hist −209‎ m Subrahmanyan Chandrasekhar ‎ →‎Early career: This sentence was redundant. Tag: 2017 wikitext editor
17:4317:43, 4 March 2021 diff hist +1,276‎ Talk:Friedrich Georg Wilhelm von Struve ‎ →‎Struve or Bessel?: There are two pages that are inconsistent, so they should really be resolved. I don't know the answer definitively, but if the past comment is right, it really should be on the page itself. Tag: 2017 wikitext editor

16:1216:12, 1 March 2021 diff hist +51‎ Kepler's laws of planetary motion ‎ →‎Comparison to Copernicus: See the talk section. While this section understood Kepler, it did not understand Copernicus's model. I tried to edit it in as minor way as possible, but I would be just as happy if the whole section were cut. Tag: 2017 wikitext editor
16:0216:02, 1 March 2021 diff hist +1,193‎ Talk:Kepler's laws of planetary motion ‎ →‎Supposed comparison: The comparison at the beginning of page is totally wrong and misleading. I propose we edit it out, or expand on it. Tag: 2017 wikitext editor

16:5016:50, 20 January 2020 diff hist −23‎ m User:Jwkeohane ‎ minor edit current Tag: 2017 wikitext editor
16:4716:47, 20 January 2020 diff hist +456‎ User:Jwkeohane ‎ I added a book I had recently published to my user page. Tag: 2017 wikitext editor
16:3616:36, 20 January 2020 diff hist +556‎ Talk:Impedance of free space ‎ Response to the question of why free space has impedance. Tag: 2017 wikitext editor
16:2316:23, 20 January 2020 diff hist −167‎ m Uniform number (Major League Baseball) ‎ I just cleaned up the language to make it more readable. No substantive changes were made. Tag: 2017 wikitext editor

18:3118:31, 20 March 2019 diff hist +236‎ m Magnitude (astronomy) ‎ →‎Other scales: The prior description was somewhat misleading about the Vega system. It failed to convey the concept of an absolute calibration standard, and why there was a need to replace the Vega system. It also propagated a misconception about the fundamental nature of absolute calibration. Tag: 2017 wikitext editor

16:3316:33, 20 December 2018 diff hist −2‎ m On the Heavens ‎ →‎English: I reordered the list, so it is actually in reverse-chron Tag: 2017 wikitext editor

18:5318:53, 3 March 2017 diff hist +8‎ James Bradley ‎ →‎Works: changed 'diameter' to 'angular diameter' as the AU had not been reliably measured in 1722.

21:4521:45, 29 December 2016 diff hist +299‎ Magnus effect ‎ →‎Physics: I simply integrated the relationship given over half a sphere, and wrote it in vector notation. This is very handy for simulation work. Since I did not write the previous part, I do not know what the reference "Glenn" refers to.

23:4423:44, 18 December 2016 diff hist 0‎ m Hipparchus ‎ →‎Distance, parallax, size of the Moon and the Sun: As there is no year zero, year -189 is the same 190 BC. On the Wikipedia list of these, (List of solar eclipses in the 2nd century BC) it is listed at 190 BC.

16:4416:44, 7 August 2016 diff hist +126‎ Tour Montparnasse ‎ →‎Gallery: Added a northwestern facing panorama picture.

20:3820:38, 5 August 2016 diff hist +18‎ Sacré-Cœur, Paris ‎ →‎Access: I added a 180 degree panorama of the view from the top of the Basilica.

17:5217:52, 4 December 2015 diff hist +574‎ Thermal history of Earth ‎ →‎Thermal Catastrophe: Added historical context and a link to another wikipedia page. Did not change any existing text.
