User talk:Sternenstaub~enwiki

Hi Sternenstaub. From your user name you must know about space dust. But I thought charged dust in space did act like a plasma - they are charged particles after all? Just confused. Aarghdvaark (talk) 16:04, 29 September 2012 (UTC)

Hi Arghdvaark! Thanks for the question. It's always a pleasure to talk about physics. ;-) A plasma is not just a collection of charged particles - then ordinary air would be a plasma, for instance, because you always have a few particles that are charged. In air the number of charged particles is simply so few compared to the number of uncharged particles that the charged particles are negligible. There's three conditions that must be fullfilled for a system of charged particles to be a plasma - basically, the interactions between the particles must be strong enough. They are given in more detail on the page about plasmas, actually: http://en.wikipedia.org/wiki/Plasma_%28physics%29#Definition_of_a_plasma I don't think that ordinary charged dust in space, such as the dust you can find in the rings of Saturn, interacts strongly enough to fullfill these conditions. But feel free to search the literature for this, maybe you can find some cases where they actually do interact very strongly, that would be interesting.

Your account will be renamed
Hello,

The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.

Unfortunately, your account clashes with another account also called Sternenstaub. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name Sternenstaub~enwiki that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name. If you think you might own all of the accounts with this name and this message is in error, please visit Special:MergeAccount to check and attach all of your accounts to prevent them from being renamed.

Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.

Sorry for the inconvenience.

Yours, Keegan Peterzell Community Liaison, Wikimedia Foundation 02:52, 20 March 2015 (UTC)
