Hi Oleg,
I have no plans for modular arithmetic theory. I thought per our earlier agreement that the sections on rings, music, art, applications, and 'see also' would be stripped out of the article on modular arithmetic and placed into the article modular arithmetic theory, but I see this hasn't happened. I think the current modular arithmetic article is terribly non-standard point-of-view-ish and unbalanced in its treatment (e.g its obsessed with rings and ideals and yet has absolutely no mention of group theory -- this is just plain bizarre, and is not how the topic is treated in 'mainstream' education).
I thought that the solution to this point-of-view problem was going to be to strip out the modular arithmetic article to its bare bones, keep it at a grade-school level, and then encourage all newcomers to edit the 'theory' article instead, right?
However, I don't really want to touch this prickly cactus again; I'm busy with other things.
Sorry about the spelling, I'll try harder. linas 04:53, 21 Mar 2005 (UTC)
Oleg, I'd be willing to nominate you as an admin, if you are interested.
Your time here is longer than 3 months, and you have over 4000 edits, so most people would be satisfied. There might be some reason to wait a few weeks longer - 4 months is better, in a sense.
Anyway, what do you think?

Hi Oleg, I've been reading around the maths area a lot more lately, and it doesn't seem to have many notes to help with interpretation. The articles seem great for people who need a refresher, but not so great for people needing to solidify their understanding (maybe this parallels a possible general tendency for mathematical education to focus on notation and have a total lack of essay-writing etc.). Is this is a deliberate policy or could I start adding interpretational notes without causing a ruckus? (on principle that is, maybe my style or content will cause a ruckus, but that's another matter!) Conskeptical 12:36, 27 Apr 2005 (UTC)

Hi Oleg,
a while ago I added to scalar field some formulas which are supposed to explain the difference between a vector field and a scalar field. You removed then, as I expected you to do, saying they don't make sense. I'm talking about this:
The first and third line are equations for the same scalar field, expressed respectively in cartesian and cylindrical coordinates. The second and fourth are for the vector field which has the same components in cartesian coordinates, but not in cylindrical, which is the whole point of these equations. The problem with scalar field and vector field is that they fail to mention this completely. Instead they focus on whether a function maps to R or to Rn, but that is just not the difference. I can form a scalar function to Rn simply by extending the codomain. I realize these articles talk mostly from a vector calculus standpoint, but that includes cylindrical coordinates, does it not? One bad explanation I can think of is that you do not yourself understand the difference between scalar and vector fields. Please tell me this isn't so. -- MarSch 14:17, 2 Jun 2005 (UTC)
Hi Oleg, I would like you to know that I've explained in considerable detail the difference between scalar fields and vector fields. Please take another look at it. -- MarSch 12:40, 12 Jun 2005 (UTC)

Hi Paul. I want to ask you a favor. Somebody moved gradient to gradient (calculus). This was done without discussion, and without disambiguating the links. I think this is one of those situations in which gradient better stay what it was before; besides the other meaning now put in the gradient disambig page is also mathematical.
So, I wonder if you would agree with me that the thing needs to be moved back, and if yes, if you could do the move (since you have the admin powers). Thanks. Oleg Alexandrov 19:08, 14 Jun 2005 (UTC)
Could you try to replace MathBot's dummy edits to refresh the 'what links here' feature like this one with a so-called null edit (an empty edit without summary)?

Hi,
sorry but I was out of time and I could not really explain the Routh-Hurwitz theorem (a simple one, but the notations are really heavy...). Actually, it is useful to test the (Hurwitz) stability of a polynomial. If p-q=n where n is the degree, then the polynomial is stable. It has some other applications I will add later in the article. But to me, the Routh-Hurwitz stability criterion is just a consequence of R-H theorem. So we can either keep RHsc and explain it better or add the part to the main RHth part.. (consult e.g. [1] to have an idea of what is the criterion).
Finally, I feel there's some misconceptions about Hurwitz polynomials. Some people write that for a polynomial to be Hurwitz stable, all its coefficient must be positive. But if you multiply a polynomial by (-1), it will have the same roots so it will stay stable and have all negative coefficient...
Anyway I'll enhance the RHtheorem in a few days, cheers and thanks for your help Julien Tuerlinckx 12:28, 19 Jun 2005 (UTC)
The mathbot robot just changed "focussed" to "focused" in General Relativity but both spellings are acceptable. There are some cases where two spellings are permissible, but one is preferable, as in "buses" vs "busses" because the second can mean vehicles or kisses, but you might want to allow "focussed." There are many similar cases, such as "traveling" or "travelling." Pdn 00:45, 20 Jun 2005 (UTC)

The context of this article needs to be improved. This all started when I started the disambiguation page precision. Def (1) on that page refers to the precision of measurements and points to accuracy and precision where those concepts are elucidated and discussed. Def (5) decimal precision redirects here to an article that I originally wrote within that specific context. However, it was correctly pointed out that it applies to numbers expressed in some other radix and it was edited.
I think that it is wrong to set this in the context of measurement as this gives rise to confusion with the different use of precision in accuracy and precision. "Decimal" precision is relevant to (say) pi but that is not a measurement. Needs sorting out. Cutler 16:16, Jun 21, 2005 (UTC)

Thanks a lot for your detailed comments and remarks on my math editing. I will follow them in future.
I have one question about ISBN. I looked at your corrections on the Differential equations of mathematical physics page. The ISBN links are now okay. However, when I tried to see how you did it and clicked edit this page, I could not see any changes. Do I have to use square brackets as it is normal for making links?
