Hi, 3p1416. This is 2e7183 (just kidding ...)

Seriously, I ran across your new article Control of chaos, and noticed a red link for your talk page. So I just stopped by to say hello. Here's another page you might want to visit from time to time. A bunch of the mathematicians on Wikipedia get together there to kick things around.

Have a great day! DavidCBryant 13:10, 20 February 2007 (UTC)

Control of Chaos
Hello! It's me again.

Say, I just edited Control of chaos. You might want to look it over to be sure you approve of my edits. I did want to point one thing out, which might not be obvious. You had coded a category tag as "Category:Chaos theory|*". I changed that to "Category:Chaos theory". The little "|*" bit identifies the article in which it's found as the primary article for that category. I think Chaos theory should be the main article for "Category:Chaos theory", and your new article should appear as a sub-heading within the category. DavidCBryant 14:09, 20 February 2007 (UTC)

Thank you and UPOs
Hello David,

Thanks a lot for your warmth welcome, for your help, and for your advice that will be taken into account. As you will notice, I reversed only one of the changes that you did to “Control of Chaos”: the skeleton of a chaotic attractor is made of truly periodic orbits. Although unstable, these orbits are properly periodic. They are not more or less periodic as “almost-periodic” suggests. Anyway, I feel that the remainder of your editing has improved the article. Thank you again. 3p1416 11:36, 22 February 2007 (UTC)


 * Hi again, 3p1416. Sorry to be so slow about writing back.
 * I don't want to argue, exactly, but I'm a little puzzled by your insistence that "almost-periodic" is wrong. I understand that there are periodic orbits inside of chaotic attractors. The problem is that in the real world one can't precisely control the trajectory of say a charged particle. One can make the particle approach the stable (periodic) orbit, but the error inherent in the real world mechanism does not permit one to nail the perfect orbit precisely.
 * I guess the distinction is between the periodic orbit (which can be shown to exist) and the almost-periodic orbit in which the real particle/system moves. Not that it's a big deal, but I'm still puzzled by your edit.
 * On another topic (in the same article), I notice that User:Tim.bounceback put a "noofootnote" tag on the article, and you promptly removed it. What Tim wanted you to do was to put a footnote or two in the body of the article. I can help you get that done, if you just let me know which of your two references describes the Pyragas method, and which describes OGY. Or are both methods covered in both books? I don't know, because I don't have either book handy.
 * Have a great day! DavidCBryant 13:06, 25 April 2007 (UTC)
