Reader Sibille had asked in a comment to a post about “some music in Marzahn“:

Isn’t that Parkbühne located witin a residential area? Aren’t the inhabitants of that area disturbed by the noise which is caused by such a band?

on the attractivity of locations: refurbished buildings in Marzahn-Hellersdorf, among them the now newly renovated Rhin Towers

I have found Maxwell’s equations of human behaviour!

A sort of brief follow-up to the last two posts about simulations. Here a link to Tim’s simulation of a critter under the couch.

As described in the last german TAX post I was trying to get information about german income taxes, in particular I wanted to get the concrete formulas. I asked via fragdenstaat.org at the Federal Agency for Civic Education (Bundeszentrale für politische Bildung: BPB) for that information, since they have a webpage about income taxes. This page however cited only a little phrase, with the names of the different income zones before I wrote the letter, but luckily it got meanwhile at least a little revamped. However the page still doesn’t show the formulas, moreover it is not very up-to-date. In addition the BPB was not only not able to help me with my request, but I was told that:

” In Bezug auf weitere steuerrechtliche Auskünfte bitte ich Sie, von Anfragen bei der bpb Abstand zu nehmen, weil wir definitiv nicht dafür zuständig sind.”

(translation without guarantee: with regard to further tax law requests I ask you to precind from sending further requests to BPB, because we are definitly not in charge for this.)

I should maybe also mention that I asked a representative of the ministry of economics for the formulas, who said I should ask a tax consultant.
As already said in the comment at fragdenstaat.de I had then finally found formulas for the taxes 2010-2012 (after a long search). The formulas are on the site of the ministry for finance with the taxcalculator and you can get the formulas if you type in any income, and then hit the button “BERECHNEN”. I couldnt however find the formulas for the original draft for the taxes for 2013 from February last year, neither the formulas for the new draft as of december 12 last year for the taxes for 2013. Mr. Liebig, who runs the website www.lohn-info.de had however found them and had included the numbers on his site, so I wrote him an email and asked him for the links.
I have meanwhile got an answer from Mr. Liebig who had kindly send me the links via email.

A document which describes the taxes for the upcoming year, as of 121212 is at the website of the Bundesrat.

A document which was the old draft for the 2013 taxes and which was intended to mitigate the impact of higher taxes due to BRACKET CREEP is at
http://dip21.bundestag.de/dip21/btd/17/086/1708683.pdf

I meanwhile included the new numbers into the formulas. Details (in german) and the mathics code can be found after the click.

The result in short: If I didn’t miscalculate then there are tax reductions of 8-24 Euros/year for the incomes above 13500 Euros per year. For incomes of 8100 Euro to 13500 Euros there is a tax increase of about 15 Euros/per year. The procentual bracket creep (not sure wether this is called this way, please look at formulas) is for 6% income increase maximaly about 2.5%, for 2% income increase it is about 0.8%.

I am currently spending too much time with trying to get informations about
german tax laws. If you speak german you can read the discussions at
fragdenstaat.de, which sofar ended up with me writing an Income-tax calculator for 2012 (see image), which you can use at mathics.org without any guarantee of wether the calculations are correct.

Some friend must have forgotten his/her keyring on our kitchen table. For those who have visited us: Please have a look at the images after the “read the rest of the entry” and let us know wether you miss it.

Schöne Feiertage – have great holidays ! from Berlin-Marzahn*

(*a district of Berlin which was recently even mentioned in the New York Times!)

The last blog post received quite some comments which I would like to answer. So reader Jared Khithim asked about the use of my proposals for a pre-preprint achive:

..this seems to be a quite clear violation of your copyrights! Are you going to sue Holtzbrinck?

Reader M. Boulangel saw this similarily and wondered wether I wouldn’t like to set up my own preprint archive and last but not least reader Mandy asked about the CC-10 birthday party:

…is boring talks the new berlin party scoop?

So regarding the copyright issue: No – I don’t want to sue Holtzbrinck. In fact it’s not only that I find my suggestions not overly original and rather intuitive but also that I think that it’s good that at least some people care about the issue. Moreover I don’t want to set up a preprint archive – I actually had already set up** and maintained a preprint archive for almost ten years at the former sfb288 which starts with lecture notes* by Ludvig Faddeev from autumn 1991.

I could also imagine that eventually some kind of pre-preprint archive may exist already at some institution, as there are meanwhile many institutional repositories. Or there may be related projects. Like for the Mimirix project we used trac for (amongst others) reading the students works and who knows wether there aren’t universities who already set up their own online dissertation pre-print archive. I still think it would be good to have something like this with a long term support offered by a global public institution like the arxiv.org. A company like Holtzbrinck has to keep its own business interest in focus and this may unfortunately turn out to be eventually at some point against the original idea of science.

Concluding – I eventually would use my “copyrights” passively, that is in case someone would e.g. try to forbid the arxiv.org to set up such a thing, because of copyright issues (there are still software patents in the US) then I could eventually try to help the arxiv with my timestamped proposals, which are distributed over the internet. But I don’t think that this is going to happen.

*the preprints have no licence, since back then a kind of creative commons share-a-like licence was sort of self-understood for preprints, I actually don’t know how the arxiv handles these new laws.
**with technical help from colleagues

Regarding the party… the party of course started after the talks, images after the click.

Leonard Dobusch and John Weitzmann at the CC-10-birthday party

randform hasn’t yet reported on a rather new online tool in scientific publishing which is called figshare. The german reader may have already read about it in an article by Aleks Scholz at the blog Riesenmaschine, the scientific minded reader may have used it already.

Tanz im Aufbauhaus inspired by 90’s hip hop music, Klaus Nomi, Kraftwerk, Nina Hagen and the Megaphoneannouncements at S-Bahnhof Friedrichsfelde-Ost.

The song is about humans and machinization. Translation eventually later.
