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. John R. Brews 16:23, 24 August 2011 (UTC)

In particular, the concept of "matter" is treacherous, and has evolved considerably over time. John R. Brews 16:27, 24 August 2011 (UTC)

To elaborate a bit: the Greek idea of atoms became the indestructible atoms of the 19th century, then were replaced by indivisible electrons, protons and neutrons, then replaced by the indivisible quarks and leptons and the bosons they exchange (or maybe only the gluons, as photons aren't included; the contributions to matter are a bit fuzzy). At each stage, matter took on a new definition, allowing a wider and wider range of forms of matter, for example, the quark-gluon plasma, which can't even be defined from the view of matter as an assembly of atoms. John R. Brews 16:45, 24 August 2011 (UTC)

John, thanks for your advice on how to approach a 'student level' treatment of electric charge. I think both approaches you described have their pedagogical merits. I'd like to find a coherent way to include both approaches.

I'd wanted to develop a complete draft of the 'student level' subpage before presenting it, not wanting to waste your time. But your helpful comments show your interest, so I'm inclined to seek your comments as I develop the draft. My earliest notes you can read at http://en.citizendium.org/wiki/User:Anthony.Sebastian/Sbox01. They are quite embryonic.

My thought is to start somewhat oversimplified, then introduce the complexities later. First an introduction based on the basics of our modern understanding, then, in a separate section, an historical account along the lines you mentioned above. Anthony.Sebastian 23:30, 24 August 2011 (UTC)

Anthony: The outline at your sandbox is at a pretty early stage. At the moment it seems to aim at some ideas that lead to Coulomb's law, expressed in words. It is not necessary to base matters upon atoms, electrons and protons to do that, and historically that was not the path. As you know, electricity began with charged objects like rubbed amber, and the inverse square law was established by Cavendish and Coulomb without reference to atoms. Atomic concepts have their own subtle history in chemistry and are themselves much more complex concepts than the notion of electric charge. Possibly, after charge is established as a notion, it can be applied to atoms, if that seems desirable. John R. Brews 14:21, 25 August 2011 (UTC)

John, here's how I see my starting aim: to explain electric charge in today's science, at a level of explanation accessible to an educated general audience, assuming that their knowledge includes no more than a secondary-school level of knowledge of science, including that matter consists of atoms and that atoms consist of protons, neutrons, and electrons in the solar system (Bohr) model. In between textbook and popscibook, closer to textbook.

I agree that knowing the history of the development of the concept of electric charge importantly enriches one's grasp of the concept, but as the starter for a student-level treatment of electric charge, I personally find it better first to help the student acquire/enhance some grasp of the basic concept. Anyway, that's how it works for me as I try to increase my knowledge of physics and chemistry—and without having to know/learn advanced mathematics, I might add (no pun intended).

Ideally, I would hope to integrate the two approaches into a single woven narrative. I see the project taking months to accomplish, given the time I can devote. In the end, I'd like to see positive responses from secondary-school students taking an academic curriculum.

I can't express how satisfying it is for me to have your input helping me organize consciously my thinking. Anthony.Sebastian 22:35, 25 August 2011 (UTC)

Boxed comments in your articles

Hi Anthony:

Your recently amended contribution Herophilus contains some very long boxed instructions for the novice reader of CZ (or any other wiki for that matter). In the article Vesalius I trimmed this boxed content without encountering objections from you (thank you), but your article Herophilus possibly has extended this text beyond even what was originally in Vesalius. Here is what I refer to:

Most citations to articles listed here include links — in font-color blue — to full-text. Accessing full-text may require personal or institutional subscription. Nevertheless, many with do offer full-text, and if not, usually offer text or links that show the abstracts of the articles, free without subscription. Links to books variously may open to full-text, or to the publishers' description of the book with or without downloadable selected chapters, reviews, and table of contents. Books with links to Google Books often offer extensive previews of the books' text.

and here is my trimmed version:

Many citations here include blue links that open variously to full-text or to a publisher's description of the work. Links to Google books often offer an extensive preview of the text.

Of course, I am not a novice reader of CZ or WP, and what is said in these boxes is of no interest to me at all. Hence, I might be expected to find this boxed information a distraction.

Although I cannot put myself in the frame of mind of someone reading Herophilus as my first ever encounter with a wiki article, my best imagining of this situation is that it is overkill even for such a novice. More than that, thinking of the average reader, I suspect very few will encounter Herophilus as their very first article.

Probably (IMO of course) general observations of this kind are better placed in some kind of "Advice to the Novice" article along the lines of Google's tips for effective search. You will notice that Google does not include this kind of instruction on its primary search page. If it were thought helpful, a link to the "Aid to Novices" instruction article could replace the boxed instructions you are wont to include in every article.

Maybe you would reconsider your approach to boxed guidance to the uninitiated? John R. Brews 16:19, 18 September 2011 (UTC)

John, I agree that the boxed information note not necessary for most readers. I removed it from Herophilus, and will eliminate it from other articles as they turn up.

I appreciate your interest in the articles I'm working on, and grateful for what I'm learning from you. Sometimes I'm a little overzealous in spoon-feeding readers. I like your idea re link to Advice for New Readers article. Anthony.Sebastian 03:52, 19 September 2011 (UTC)

Anthony: I'd say you're eminently qualified to write an Advice for New Readers page. It could include the content of your text box, and a few more things too, like finding the CZ: xxx pages identified at CZ:Home and what's in the left-column links. This new article should be linked among these left-column links and made a CZ: xxx page. John R. Brews 14:58, 19 September 2011 (UTC)

Thanks for the compliment, John. First, I've got find where my clone disappeared. Or, I've got to get my time-stopping machine working. Anthony.Sebastian 03:28, 20 September 2011 (UTC)

Change of figure

Anthony: I replaced this figure of yours:

(CC) Image: Anthony Sebastian (adapted from data from Wolfram Alpha)

with this one:

(PD) Image: John R. Brews

which compresses the horizontal scale allowing a narrower display on a laptop screen. It also uses the same years at each tick in each panel, and an interval of 20 years in all the panels, which makes it easier to read the lifetimes from the scales, and lines up the scales in each panel so the same years are vertically above one another.

I hope these changes find favor. John R. Brews 16:44, 4 October 2011 (UTC)

Nicely done, John. I was never too happy with my original, and had it on my list to redo, plus add a caption describing the anatomy-to-physiology-to-microscopic anatomy sequence represented by those three fellows in the history of medicine. Also you remind me, unintentionally, to get back to the Harvey and Malpighi articles.

BTW, what program did you use to make the image? Anthony.Sebastian 02:13, 5 October 2011 (UTC)

Anthony: Glad you liked this. It was made using Microsoft Excel 2010 and saving the result with Microsoft Paint. Excel 2007 was OK for this too, but the earlier Excel versions are more restricted in their choices of colors and shadings. You might be able to do the same using Word instead of Excel. John R. Brews 05:12, 5 October 2011 (UTC)

Anthony, I thought your new figure looked very nice, so I tried something like that myself. See below, right.

The issue comes up that some people don't live long enough to allow a box containing their names. I tried one "solution", color inside the name box. Do you have some other ideas?

Nice job. John R. Brews 22:10, 9 October 2011 (UTC)

John, thanks. I just wanted to do a test, not to supplant your fine figure in Vesalius, rather thinking of future articles.

Re the short-lived notables:

• adjust width of timeline to accommodate non-fitters
• reduce font-size as needed; shouldn't jar too much
• color in box, but leave off box border; might need caption note

All I can think of. Anthony.Sebastian 03:31, 10 October 2011 (UTC)

Hi Anthony: I tried out your suggestions and settled upon the last one: image here is updated.

Thank you. John R. Brews 11:12, 10 October 2011 (UTC)

Looks great, John. Go for it. Anthony.Sebastian 18:59, 10 October 2011 (UTC)

Language Evolution

Hi Anthony, there is a discussion over at this page about a potential move for this article. Could you take a look? David Finn 12:32, 19 November 2011 (UTC)

Hi Anthony, there are more comments over at this article, but before you look may I make a suggestion.

Since this article is the only one on Citizendium with "synopsis" in the title, how about I move the article to Language Evolution (book) and attempt to write a short introduction about the book, followed by all the text that is currently there. I think that may solve any issues. What do you think? David Finn 12:14, 21 November 2011 (UTC)

Yes. I regretted 'synopsis' almost from the beginning, but was somewhat intimidated by the 'move' procedure, though I've done it now a few times. Thanks for your help and comments. Anthony.Sebastian 14:24, 21 November 2011 (UTC)

Query about Vesalius

Anthony: I do not have access to the book you use as source for the idea that Vesalius succeeded where Galen did not because of the more liberal access to cadavers in Vesalius time. See my inquiry about this matter. It appears likely that there was a reduced restriction in Vesalius' time. One might consider that Galen might have succeeded too in Vesalius' place, but the way this is stated suggests that it was a piece of cake for Vesalius because of the reduced restrictions.

There is also a lot of literature including some of very recent date that take the view that censorship was a problem for Vesalius. I have found it hard to determine whether what we have here is simply the repeating of tales heard at a mother's knee, or something more accurate.

Can you help? John R. Brews 19:02, 19 November 2011 (UTC)

Will review this matter, John. Anthony.Sebastian 05:04, 23 December 2011 (UTC)
