Hello. You seem to be one of those newbies who insist on beginning each article with a noun phrase rather than a complete sentence. I have corrected these problems in your flight mechanics article and in life extension. Michael Hardy 23:04 Apr 23, 2003 (UTC)

I have now edited all of the articles referred to on your user page. You seem to have a habit of writing several consecutive phrases that are not sentences where sentences should appear. Michael Hardy 23:15 Apr 23, 2003 (UTC)

Flux & Potential

edit

In the lowly task of cleaning up after my disamb of Battery, i found myself puzzling over the red links in Potential difference & Flux, re thru and across variables, but eventually got around to puzzling over this satisfying but for me obscure generalization of what, would you say field theory? Fine intellectual calisthenics for me, and glad to have found them.

But i'm concerned that elecrical PD is what almost everyone comes to Potential difference in order to understand, and it may be a terrible hurdle for the high-school seniors and non-major undergrads who come to the page to brush up on that. I was delighted to find reasonably recent edits on your Contributions, bcz i doubt i could do a very good job of what i am thinking; i hope you'll find the suggestion at least worth mulling.

It seems clear to me that Potential difference was incomplete w/o the initial paragraph and list you edited in. But most readers will not realize they can skip it for their purposes. (It strikes me as a situation similar to those solved w/ a page where a long article on Foo begins with a link to Foo (disambiguation), a short page that may lead only to stubs and red links. I don't mean that Potential difference (disambiguation) would serve for a place for the material you added, but i've no confidence in the titles i'd suggest, like Potential difference (generalization).) What i'm picturing is

This article concerns electrical potential difference, the most common sense of potential difference.
Strictly speaking, potential difference is a much broader concept discussed at Potential difference (whatever).

Would this make any sense in your view? --Jerzy 22:42, 2003 Dec 4 (UTC)

Through/Across Resistor?

edit

You wrote at a section of my talk that

The through variable does not change over the lumped parameter (e.g. resistor). Current on one side of a resistor is equal to current on the other side. The voltage, on the other hand, differs. So the voltage differs ACROSS the resistor.

Arriving here to leave you a confused note, i found myself rereading above what i wrote you in Dec. (which already is unfamiliar to me!). Now it sounds like you are motivating for me the through/across concepts (and not pointing out something stupid i said elsewhere). What would i do next with this useful-feeling clarification? While i finally came up with the word "flux" (and was then able to stop obsessing about how much i've forgotten abt divergence and curl), am i going astray by trying to generalize at this point beyond lumped parameters to spatially varying ones? E.g., trying to think abt, maybe, a volume bounded by

  • two different equipotential surfaces and
  • a surface everywhere parallel to the thru-variable, in our case charge-flux (= vector current density?).

And the corresponding condition of no change in net charge inside it?

Would i be better off just at some point rereading your article 'graph with these motivating ideas in mind? Should i drag out Maxwell's equations, undertaking the "exercise left for the student" of IDing the magnetic thru and across variables without peeking at the article (and [shudder] without trying to identify the lumped parameters)?

Thanks for your attention. (And i'd also welcome any thots on the questions i did ask originally, if you choose.) --Jerzy 19:44, 2004 Feb 3 (UTC)

South African Collaboration of the Week!

edit

Hello, this is just a brief, friendly announcement to let you know that there is now a South African Collaboration of the Week where we vote every two weeks to select an article about South Africa that is either a stub or nonexistent and attempt make it featured article quality by the end of the week. Your comments, voting, and participation would be very welcome! PZFUN 17:45, 25 Nov 2004 (UTC)

Speedy deletion nomination of Datacoin

edit
 

If this is the first article that you have created, you may want to read the guide to writing your first article.

You may want to consider using the Article Wizard to help you create articles.

A tag has been placed on Datacoin, requesting that it be speedily deleted from Wikipedia. This has been done under section G4 of the criteria for speedy deletion, because the page appears to be a repost of material that was previously deleted following a deletion discussion, such as at Articles for Deletion.
