Please review Los Alamos National Laboratory for spelling, grammar, and whatever

Anthony, I would very much appreciate it if you would review Los Alamos National Laboratory for spelling, grammar, and whatever else you think may be needed. Let me have your comments on the article's Talk page. Thanks, Milton Beychok 20:33, 6 June 2011 (UTC)

Hi Anthony

Back after a holiday - I take it I'm not still needed for Alcmeion?Gareth Leng 08:39, 14 June 2011 (UTC)

Thanks, Gareth. Alcmaeon (a.k.a., Alkmaion): Approved. Hope you enjoyed your vacation, though you may have meant 'vacation from CZ'. OMBs need such. Anthony.Sebastian 22:31, 14 June 2011 (UTC)

Asking for your help again

Anthony, the Project Apollo article needs a critical review by a History author like yourself. See here the documentation of my recent extensive edits to that article.

Anything you can do to make it more readable, more interesting, etc. would be appreciated. Milton Beychok 04:00, 21 June 2011 (UTC)

Milton, I have a few deadlines related to academic year ending. I took a look at Project Apollo and will plan to work on it starting sometime in July, though the start of the academic year also puts demands on me.

Thanks for steering me in the article's direction. The Apollo missions were incredible achievements. Anthony.Sebastian 14:39, 22 June 2011 (UTC)

Anthony, thanks for your added references and edits as well as for picking up my goof in defining "billion". Milton Beychok 21:57, 24 June 2011 (UTC)

Redirect of Biological mathematics

Hi Anthony: I've moved the article Biological mathematics to Biological computation, which seems to me to fit the content of this article pretty well. Please excuse my doing this before your have had a chance to comment upon it. I don't think it is a very controversial change, but it may be a bit startling to find what has happened in your absence. If so, my apologies. John R. Brews 18:51, 4 August 2011 (UTC)

Electric charge

Anthony: If you take a look at Talk:Electric_charge#Definition_of_electric_charge you will see that while technically you are right that the article Electric charge should begin with a definition of electric charge, that approach is awkward, and the simple change you have made in the lead sentence of this article does not solve the problem.

There seems to me to be two possibilities: the one you object to that begins by defining charge and then defines electric charge and how it is distinct from magnetic charge. Alternatively, one can make a new article Charge, describing a fundamental property of matter that causes matter having that property to generate and react to a force of attraction or repulsion to spatially separate matter that likewise manifests the property of charge.

Then one can refer to this article in the article Electric charge as one of the two known types of charge, magnetic and electric, with the distinguishing property that electric charges can be isolated, while while an isolated magnetic charge or magnetic monopole never has been observed.

In any event, I find the present arrangement unsatisfactory. John R. Brews 04:09, 13 August 2011 (UTC)

Apparently the matter is complicated further by the concept of "color charge". John R. Brews 15:51, 13 August 2011 (UTC)

Also complicated by mass: "In physics, mass is an extensive physical property of a system and is most frequently measured in the SI unit of kilograms. Mass is the "charge" of the gravitational force, and the resistance an object has to force." From CZ article.

I like the idea of dealing with 'charge' in a separate article, Charge. I too was thinking of that, but I did not feel qualified to do it justice. I suppose we could start it as a stub, with the lede sentence you suggested. I give it a try, unless you really want to do it yourself. I'm away Sunday, could do it Monday.

At any rate, in Electric charge, I had wanted the reader to know a bit more about electric charge before introducing magnetic charge, or charge in general. Anthony.Sebastian 04:31, 14 August 2011 (UTC)

A start at an article. John R. Brews 05:44, 15 August 2011 (UTC)

The treatment of color charge and its connection to nuclear forces needs work. John R. Brews 14:01, 15 August 2011 (UTC)

I set up a talk page to consider how this article should be written at User:John R. Brews/Sample/Talk. John R. Brews 16:23, 15 August 2011 (UTC)

Anthony: Perhaps a god approach to Charge is to make it a disambiguation page. There are so many different "charges" even within science that it seems they are almost unconnected. For example, Charge (electromagnetic) could include both electric and magnetic charge, replacing the present Electric charge. Charge (chromodynamic) could discuss color charge. Then we are left with Charge (baryonic), Charge (leptonic), which appear to be different in that they are not related to forces at all, but to symmetry classifications. Maybe you have some more?

Although mass is related to the force of gravity by the same potential theory as electromagnetism via Poisson's equation, it is not referred to as a "charge" in physics texts (a Google books search does not turn up this terminology, despite its use in the CZ article Mass), and is ultimately related to the curvature of space time, a form of "fictitious" force depending upon the observer like centrifugal force.

The disambiguation page would have to include non-science versions too, of course, like Charge (military), Charge (explosive). Maybe you have some more? John R. Brews 14:15, 18 August 2011 (UTC)

John, it appears we already have Charge as a disambiguation page, automatically redirected from Charge. It currently has three entries:

• Charge (electricity) [r]: The potential of a physical system to provide or accept electrons. ^[e] (that is just a lemma)
• Charge (management) [r]: Add brief definition or description
• Charge (retail) [r]: Add brief definition or description

I would prefer separate articles on Charge (science), Electric charge, Magnetic charge plus the ones you suggested: Charge (chromodynamic) Charge (baryonic), Charge (leptonic), Charge (military), Charge (explosive), Charge business, Chargés d'affaires, etc.

By Charge (science), I refer to the Sample article you started.

I do not ignore your Charge (electrodynamic), but in the interests of the readers, separate articles on electric and magnetic charges would seem better, as each deserves it own treatment in order to do it justice and teach the unique aspects of each. —Anthony.Sebastian 21:28, 18 August 2011 (UTC)

Your introductory charge article

Hi Anthony:

As you know, there are several ways to introduce a subject. One is to present the current understanding from a logical standpoint supported by today's experimental data. That method depends upon an abstract turn of mind that enjoys an axiomatic approach, related by experiments to reality. These concepts and data are not necessarily naively intuitive.

Another approach is historical. That method begins in the past and works to the present. Its goal is not to be historically accurate in explaining all the false steps and all the confusions of the historical record. Rather, the goal is to adopt the naive view of each epoch and show how that sharpened and evolved with advances in argument and experimental data. This method is helpful to beginners, because the early work has the same naivete as the readers themselves, and so they can advance in understandable steps toward the less intuitive, more involved, present view.

I'd recommend the last approach to you. There is no point in trying to present a simplified approach based strictly upon concepts from an early time that are now outmoded. Instead, any overly simple concepts are presented as the tentative approach peculiar to a certain epoch, expected to be transcended, and are not presented as a logical structure still considered appropriate.
