Hallo
Ich heiße HappyCamper. Ich habe erst im Mai 2005 begonnen, Deutsch zu lernen, deshalb spreche ich diese Sprache noch nicht perfekt, aber sie gefällt mir sehr. Ich habe gedacht, ich könnte mein Deutsch etwas verbessern, indem ich ein wenig an der deutschsprachigen Wikipedia mitarbeite, also versuche ich, hier mitzumachen ohne irgendetwas in Englisch zu schreiben. Es ist nicht verboten, mein Deutsch zu korrigieren, im Gegenteil, ich bitte sogar darum! ;-)
Ich bin Admin in der englischen Wikipedia: en:User:HappyCamper

Idared - mein erster Artikel!
Vielen Dank für das Aufpassen auf meine Beiträge.

Subpage organization
I've placed my user page in my sandbox here at Benutzer:HappyCamper/Spielwiese. This way, I can translate my articles in my userpage, and move them into the main article space when they are ready. The article that I will be working on can be found here: Benutzer:HappyCamper/Artikel. Feel free to help me out with the translation! I think I will try translating en:nondimensionalization first. It is one of my favourite articles on Wikipedia, and would be nice to have a German version of it too.
Interwikilinking
There are a number of important administrative sites on en: which do not have reciprocating interwikilinks (not intrawikilinks) to de: -- considering that German Wikipedia is the second largest Wikipedia, it would be nice have these links set up, so observers can see how policy has evolved over time between the two projects:
Stuff for me to go find and seek include: (please feel free to help out)
- en:Wikipedia:Administrators' reading list
- en:Wikipedia:Blocking policy
- en:Wikipedia:Administrator intervention against vandalism
- en:Wikipedia:Vandalism in progress
and many many more...
What about our beloved CryptoDerk's Vandal Fighter at en:User:CryptoDerk/CDVF? I'm sure it would be wonderful for the admins to use it here as well :-)
For comparison purposes, these are also quite interesting...en:Wikipedia:Requests for adminship and Wikipedia:Adminkandidaturen.

Deutsche Grammatik
- beziehungsweise (bzw) - means "respectively" - see for example, wikt:bzw.
Verben ich kenne auf das Präsens
- sein (ich bin, du bist/Sie sind, er/sie/es ist, wir sind, ihr seid, sie sind)
- haben (ich habe, du hast/Sie haben, er/sie/es hat, wir haben, ihr habt, sie haben)
Deutsche Anmerkungen für mich - Danke den Wikipedianern hier
- "Artikel" ist genus maskulinum ... Gemeint ist: Es heißt: Der Artikel Gruß, Wolfgang Feld
- zu den Verben: Die dritte Person Plural kann „Sie“ lauten, wenn es dir um das (höfliche) Ansprechen einer oder mehrerer Personen geht. Es kann aber auch „sie“ heißen, nämlich dann, wenn es um mehrere Personen geht, die du nicht ansprichst. Beispiele: - Können Sie mir helfen? - Danach gingen sie ein Eis essen. Ich hoffe, du hast den Unterschied verstanden (wenn du ihn nicht ohnehin schon kanntest) und ich bin hier richtig (und nicht auf deiner Diskussionsseite). Gruß --Stefan ■ 12:39, 16. Okt 2005 (CEST)

Nondimensionalization is the partial or full removal of units from a mathematical equation by a suitable substitution of variables. This technique can simplify and parameterize problems where measured units are involved. It is closely related to dimensional analysis. In some physical systems, the term scaling is used interchangeably with nondimensionalization, in order to suggest that certain quantities are better measured relative to some appropriate unit. These units refer to quantities intrinsic to the system, rather than units such as SI units. Nondimensionalization is not the same as converting extensive quantities in an equation to intensive quantities, since the latter procedure results in variables that still carry units.
Nondimensionalization can also recover characteristic properties of a system. For example, if a system has an intrinsic resonant frequency, length, or time constant, nondimensionalization can recover these values. The technique is especially useful for systems that can be described by differential equations. One important use is in the analysis of control systems.
Many illustrative examples of nondimensionalization originate from simplifying differential equations. This is because a large body of physical problems can be formulated in terms of differential equations. Consider:
- List of dynamical systems and differential equations topics;
- List of partial differential equation topics;
- Differential equations of mathematical physics.
Although nondimensionalization is well adapted for these problems, it is not restricted to them. An example of a non-differential-equation application is dimensional analysis.
Measuring devices are practical examples of nondimensionalization occurring in everyday life. Most measuring devices are first calibrated relative to some known unit. Subsequent measurements are made relative to this standard. Then, the absolute value of the measurement is recovered by scaling with respect to the standard.
