Quote query

"He was subsequently educated by James Hamilton (curate of Trim), his uncle and an Anglican priest." - does this mean he was educated by his uncle, James Hamilton, who was an Anglican priest, or does it mean that he was educated by three people, James Hamilton, an unnamed uncle, and an unnamed Anglican priest??? 84.66.32.134 15:30, 23 Apr 2005 (UTC)

needs work

This entry needs a lot of work. For example:

In 1827, Hamilton presented a theory that provided a single function that brings together mechanics, optics and mathematics. It helped in establishing the wave theory of light. He proposed for it when he first predicted its existence in the third supplement to his "Systems of Rays," read in 1832.

What does proposed for it mean? Predicted the existence of WHAT??

For some reason there is a brief discussion of the incredibly important `Hamiltonian' approach to classical mechanics at the end of the section on quaternions. The Hamiltonian approach is vastly more important than the quaternions - and I say this as a huge fan of the quaternions. It should be treated together with his other work on dynamics.

Mathematician

Although Hamilton had of course a huge influence on physics, he was a mathematician and without exception referred to his own work as mathematics. VWA (talk) 08:28, 10 January 2018 (UTC)[reply]

I changed it into: mathematician, astronomer and mathematical physicist. That in his days Hamilton was certainly also seen as an astronomer can for instance be seen by this quote from the second volume of Graves' biography, regarding the 1842 meeting of the British Association in Manchester: "The Athenaeum mentions that peculiar interest was excited by the presence of the three great astronomers, Bessel, Herschel, and Hamilton, who were seen seated together on the platform." https://archive.org/stream/lifeofsirwilliam02grav#page/386/mode/2up VWA (talk) 23:40, 26 January 2018 (UTC)[reply]

It is requested that an edit be made to the semi-protected article at D. (edit · history · last · links · protection log)

This template must be followed by a complete and specific description of the request, that is, specify what text should be removed and a verbatim copy of the text that should replace it. "Please change X" is not acceptable and will be rejected; the request must be of the form "please change X to Y".

The edit may be made by any autoconfirmed user. Remember to change the |answered=no parameter to "yes" when the request has been accepted, rejected or on hold awaiting user input. This is so that inactive or completed requests don't needlessly fill up the edit requests category. You may also wish to use the {{ESp}} template in the response. To request that a page be protected or unprotected, make a protection request.

The new entry (Dec 2017) on Hamilton's private life needs editing. Hamilton was not rejected by Catherine Disney and he certainly did not propose to Aubrey de Vere. Moreover, the entry comes from one source which does not seem to claim to be an original biographic one. I cannot cite from our own work in which we give a far more positive view on the private lives of Hamilton and his wife and discuss where this extremely negative view came from, https://doi.org/10.1080/17498430.2017.1400821, and therefore I would like to ask someone who thinks we have a point, or not, to consider editing this entry.

Quaternions

In the article Quaternion it is stated about Olinde Rodrigues and the discovery of the quaternions: "Important precursors to this work included Euler's four-square identity (1748) and Olinde Rodrigues' parameterization of general rotations by four parameters (1840), but neither of these writers treated the four-parameter rotations as an algebra.[7][8] Carl Friedrich Gauss had also discovered quaternions in 1819, but this work was not published until 1900.[9][10]" That seems to me much more nuanced than the remark in this article: "The other great contribution Hamilton made to mathematical science was his discovery of quaternions in 1843.[12] However, in 1840, Benjamin Olinde Rodrigues had already reached a result that amounted to their discovery in all but name.[13]" Since I am not a mathematician I will not alter the text, but give the comparison for consideration.

Hello,

Apologies, as I don't understand how to edit wiki talk articles, but I wanted to add my opinion here.

I was reading the "Personal Life" section, and I read this: "Hamilton's married life turned out to be difficult and unhappy as Bayly proved to be pious, shy, timid, and chronically ill."

My own personal feelings is that this too subjective to be in an encyclopedia, especially since the article referenced is focused mainly on mathematics, and not personal love lifes.

I felt a little bad for hamilton, here, and I feel that characterizing his marriage as "unhappy" goes too far.

Thanks, please discuss. -Ordy~
