Talk:Foucault pendulum vector diagrams

message: Some of the ideas for this article came from reading the book "Pendulum: Leon Foucault and the Triump of Science" by Amir D. Aczel, 2003.  The diagrams were produced using a Visio program then imported as figures.  The vectors that are shown are as close to scale as obtainable by the program and was helpful in evaluating the information in the diagrams.  The words of the article are my own.  I expect many comments and edits to improve the quality and for the ideas that were the inspiration for the article.  Thanks in advance for any comments.

message: In my searches on information about the Foucault pendulum, I have come across two authors who correctly identify the force that is involved in causing the pendulum to precess with respect to the stars. One is the meteorologist Anders Persson, the other is also a meterolologist: Norman A Phillips. 
Norman Philllips has written an article that is dedicated to discussing the Foucault pendulum. it is titled: What Makes the Foucault Pendulum Move Among the Stars. The english version of this article is not publicly available on the internet (It can be purchased) 
I did find a note on the Foucault pendulum, written by Norman Phillips. 
A french version of his article is publicly available  Ce qui fait tourner le pendule de Foucault par rapport aux étoiles 
A key element in understanding the motion of the Foucault pendulum is displayed in the diagram. If the resultant force that is depicted with the blue arrow is not taken into account, then the precession of the Foucault pendulum at latitides other than the poles is inexplicable. --Cleonis | Talk 07:51, 23 January 2006 (UTC)
replies: text: The force indicated with the "blue arrow" is not the cause of the motion of the pendulum. It is due to the effect of the centrifugal force. If taken into consideration, it will cause a very small correction to the sin(lambda) law of the Foucault Pendulum. The linked articles get this wrong too (probably best to rely on physicist for this kind of analysis). —The preceding unsigned comment was added by 70.224.84.113 (talk) 15:35, 16 December 2006 (UTC)

 If the pendulum wire were a spring rather than a ridgid wire would the bob move up and down due to the Eotvos Effect?  David Harty 16:10, 12 April 2006 (UTC)

message: Why shouldn't we merge this into Foucault Pendulum?  RJFJR (talk) 14:36, 29 May 2009 (UTC)
replies: text: I'd be against merging them simply because this article is positively enormous in comparison; I think it would drown out the original article's content. What are your thoughts? Somnambulent (talk) 16:51, 29 November 2010 (UTC)
thread_title:  propose merge into [[Foucault Pendulum]] 

message: Is the reason that there is a movement of the pendulum's plane relative to distant stars when it is located at the North Pole that there uis a small torque from the rotation of the fixed point (i.e pixed point is held by the spinning Earth and twists relative to the hanging weight)?
Has anyone ever set-up a Foucault pendulum at the North Pole with a diamond point on a diamond plane swivel point to measure if the plane of the pendulum motion says fixed to a distant galaxy/star?

message: Given the oldest comment (i.e. the one by @David Harty in 2006) and the lack of distinct sources, I assume that this page (mostly) consists of original research. Since this was first written, have any of these examples and derivations made it into published sources that we could reference? BalinKingOfMoria (talk) 02:15, 19 January 2023 (UTC)
