Images

How did you upload an image without clicking on the upload link?? And how does the licensing of the image affect whether you can upload or not? — Omegatron 22:32, 9 November 2005 (UTC)

- Well.. I didn't.. I created new pages with new files by using the "Upload file" link in the toolbox. But many image pages have an "Upload new version of this file" link that allows you to directly update the file without any doubts. Fresheneesz 02:31, 10 November 2005 (UTC)

Aha! I never saw that link before. Since my images are on Wikimedia Commons, you'd have to go to the Commons description page first, and then you will see that link. — Omegatron 03:58, 19 November 2005 (UTC)

Entropy/Disorder

Hello Fresheneesz. First let me say that I am absolutely in support of the WikiData idea (it is always good to question other's data processing methods, I've seen... some interesting data processing in my time on the MER mission. Anyways, I wanted to let you know that your edits to articles involving entropy seem rather misguided. It's really a very complex part of modern physics (and not always terribly easy for individuals to understand, even with a physics degree). I think for pages like that, the majority of editing affecting content (i.e. not typographical or structural) really should be performed by individuals with credentials in the subject (and familiarity). If you feel that there's something significant missing or incorrect on these articles, I would suggest using the talk pages, it is a much better approach IMHO because then if (as in this case) your ideas don't line up with accepted modern physics, someone there can explain why.

Science is never a finished process and we have much to learn in the years ahead, but Misplaced Pages is committed to reflecting the current consensus of scientific thought on any matter, "right" or "wrong." - JustinWick 19:05, 20 November 2005 (UTC)

I apologize I'm on travel for the holidays for the next week so I'm a bit sporadic. I must admit that I am very much in disagreement with you about how best to present Entropy etc... I have several textbooks on the subject I plan ton consult in the next few days (I do need a refresher course on such thing) but I believe that it is very correct to state that entropy is, above and beyond anything else, a measurement of information content of a physical system. Yes, this is related to various free energies etc, however that is more of a "side effect" than anything else. This definition is nice for many reasons, however my favorite would be that it is unitless (well, I guess you could say it's in "bits" but that seems to be the basic unit of information in information theory). I think that defining it in terms of free energy is not only confusing (entropy is only one variable in determination of how much energy can be extracted from a system... carnot limits etc also apply). I don't have time at the moment to disect your edits (I'll get to that later) but, certainly you understand that even a maximally disorded system can have energy extracted from it with the use of a low temperature sink. I think this makes some of your edits rather erroneous (or at best, highly misleading). I also really do not see the point of tying everything back to "free energy" - sure it may be more "intuitive" for some at first, however it really hampers any actual use of the concept, as it's certainly not mathematically intuitive, and it has tenuous connections at best to micro statistical mechanics. I see you've been doing some edits on the disorder page, and I think it'd be best to define entropy in terms of information content of a system with links to that page, and free energy (where appropriate, rather than relentlessly). - JustinWick 07:25, 21 November 2005 (UTC)

2nd law vandalism

I have to go now, so please watch over the page. Don't worry about the "3 reverts rule" - it only applies for non-vandalism. If that guy keeps adding that flawed paragraph, just hit revert. :) Infinity0 00:17, 21 November 2005 (UTC)

If worse comes to the worst, you can always find an admin to lock the page and ban that IP. I don't know any personally, but there's bound to be a list somewhere. Try Misplaced Pages:Administrators? Infinity0 00:20, 21 November 2005 (UTC)

Misplaced Pages:Vandalism in progress is even better as a place to announce vandals. Yes, if vandalism is persistent, it definitely must be announced there. Oleg Alexandrov (talk) 00:47, 21 November 2005 (UTC)
