I believe this image is one of yours - if I am wrong, please ignore this message.

IMO, it would make the image better if the top right anti-color triplet was rotated so that the relative anti-color positions match that of the Venn diagram on the left. Are you able/willing to do this please?

Also what is the "G" in the diagram?

Sorry for late reply, G is the field strength tensor. I'll change the orientation later.

I am referring to v:Physics Formulae/Waves Formulae at v:Special:Permalink/1982851#Phase_Velocities_in_Various_Media which begins with this correct equation:

${\displaystyle D\left(\omega ,k\right)=0}$

When used in a WKB approximation, it can be generalized to, ${\displaystyle D\left(\omega ,{\vec {k}},{\vec {r}},t\right)=0}$. But since this approximation is only exact in the limit that there is no dependence on position or time, I agree with the way you stated it in the formulary: Once students understand the basics, they can learn the generalizations (vectors, spatial/temporal inhomogeniety) later.

But this seems to be a typo:

${\displaystyle \omega \left(k\right)=0}$

It should be replaced by something like this, to represent the fact that omega is a function of k:

${\displaystyle \omega =\omega \left(k\right)}$

See, for example http://www.wright.edu/~guy.vandegrift/shortCV/Papers/diffraction.pdf --Other than that, it is a great list of formulas! --Guy vandegrift (talk) 01:28, 5 March 2019 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2019-03-05T01:28:00.000Z","author":"Guy vandegrift","type":"comment","level":1,"id":"c-Guy_vandegrift-2019-03-05T01:28:00.000Z-Mistake_on_Wikiversity_Physics_Formulae?","replies":["c-Guy_vandegrift-2019-03-05T13:01:00.000Z-Guy_vandegrift-2019-03-05T01:28:00.000Z"]}}-->

Hello. I saw your animation on torque. I have no ability to create animations, but yours is very close an animation that I imagine that would intuitively show how precession arises. We already have animations that demonstrate what precession does, but I have not seen an animation that shows how precession comes about. If you would like to collaborate, let me know.

A tag has been placed on Jan Weyssenhoff requesting that it be speedily deleted from Wikipedia. This has been done under section G14 of the criteria for speedy deletion, because it is a disambiguation page which either

• disambiguates only one extant Wikipedia page and whose title ends in "(disambiguation)" (i.e., there is a primary topic);
• disambiguates zero extant Wikipedia pages, regardless of its title; or
• is an orphaned redirect with a title ending in "(disambiguation)" that does not target a disambiguation page or page that has a disambiguation-like function.

Under the criteria for speedy deletion, such pages may be deleted at any time. Please see the disambiguation page guidelines for more information.

If you think this page should not be deleted for this reason, you may contest the nomination by visiting the page and clicking the button labelled "Contest this speedy deletion". This will give you the opportunity to explain why you believe the page should not be deleted. However, be aware that once a page is tagged for speedy deletion, it may be deleted without delay. Please do not remove the speedy deletion tag from the page yourself, but do not hesitate to add information in line with Wikipedia's policies and guidelines.

On 8 January, 2014, in the talk page for the Color charge page, you mentioned that Roger Penrose (in his book The Road to Reality) uses the red, yellow, blue naming scheme for the colors of quarks rather than the typical red, green, blue. You also edited the page to include this information, but it has since been edited again, and so it no longer does.

In Tony Zee's Group Theory in a Nutshell for Physicists, the author adopts the red, green, yellow naming scheme, differing from both the standard convention and from Penrose. I've been looking into the origins of these discrepancies, but tragically, neither Penrose not Zee seem to cite any sources on the origin of their naming schemes. As you made reference to it in an edit of the relevant page here on Wikipedia, do you perhaps have some insight into these naming issues and their origins?

On 23 August 2012 you added a redirect from Color symmetry to Color charge with the comment "redirect for now, can expand at any time".

Recently I have created the articles Dichromatic symmetry and Polychromatic symmetry. I now propose to remove the redirect, and replace it with a disambiguation page for Color symmetry with entries for Color charge, Dichromatic symmetry and Polychromatic symmetry. What do you think?
