radio technology museum Königs-Wusterhausen, part 1

Monday, October 31st, 2016

Todays post deals with the transmission and radio technology museum at a former transmission facility in the town of Königs-Wusterhausen close by Berlin (the town is reachable by Berlin subway). The facility is located on a hill and rather big (Flight over the the facility including its museum (building with red tiles)). The museum is definitely a must-see.

Friedhof Heiligensee

Wednesday, September 28th, 2016


Sandhauser Strasse in Heiligensee next to the old riflemans house

In the randform post Heiligensee I hypothesized that an ancient oral tradition from the village of Heiligensee might indicate that cults of the germanic goddess Nerthus could have taken place there. I am fully aware that this is super speculative and in particular that it is outrageously unlikely that there is an oral tradition in Berlin which is 1500-to 4000 years old (thats approx. when the semnones lived there). It would not be too far fetched to assume that the tales of Nerthus were converted into tales matching the surroundings of Heiligensee. Nevertheless it should be reminded of that there are oral traditions which lastet for rather long time like the vedas (with by the way interesting error correcting schemes).

Anyways for me the the oral tradition was so compelling close to the Nerthus tales and to the fact that there might have been an ancient sacred location that I was motivated enough to travel to the other side of Berlin and to look for something like a sacred grove, a thing location on a raised mound and/or even a tumulus like in Old Uppsala. That is I looked at the hills across from Sandhauserstr.99 which are called Schifferberge. It should be said that in this area dune hills are rather common, so that when I started out I was quite convinced that the option tumulus was rather a joke. That is I was convinced that the Schifferberge are just dunes instead of containing a tumulus, but I am not so sure anmore. But see the images.

religious headcovers and such

Wednesday, August 31st, 2016


Me, wearing my newly acquired knotty headscar from Dublin (some of my math research involved knot theory)

School education in Germany is federal, so the choice of subjects may be different wether you live in Berlin or Bavaria. In Germany there exists a school subject called “religion”, which if obligatory may usually be substituted by an irreligious variant called e.g. “ethics.” There are still big discussions (even in Berlin) wether the subject should be obligatory or not.

A new astlab project, which comes closer to realize something which I have carried around in my head for now almost ten years.

p-values and Glyphosate animal tests

Thursday, May 19th, 2016


Dead marten in our garden. Cause of death unknown. The head was unexplainably jammed by twigs (see image). The animal was already stiff when I found it. Could have been there at most for a day.

Here a comment about a specific problem in statistics which is often ignored by (mostly) non-mathematicians.

I originally intended to leave the comment in a mathematicians forum where this problem is discussed. As an example I looked at the glyphosate Renewal Assessment Report from 2013 where I think this ignorance leads to very problematic conclusions. Warning: some details about the animal test results are rather explicit.

About maldeformation in Fallujah

Saturday, April 30th, 2016


image from Wikipedia by Vincent de Groot.

In the context of the last post about the WHO and the assessment of health problems due to radioactivity I wonder about one citation in the BBC report Falluja doctors report rise in birth defects. The BBC report was linked to from the Guardians WHO critique which I had mentioned in the last post.

According to the BBC report the citation was by “British-based Iraqi researcher Malik Hamdan:”

Ms Hamdan said that based on data from January this year, the rate of congenital heart defects was 95 per 1,000 births – 13 times the rate found in Europe.

Malik is a male name, so I guess this is a misprint and who is probably meant is Malak Hamdan.

Why did I wonder about that citation?

Commemorating the Chernobyl disaster

On the occasion of commemorating the Chernobyl disaster which happened then 25 years ago an interview with Dörte Siedentopf (a physician who has since 20 years been working in disaster relief programs for victims of the disaster and an antinuclear activist) had been published on Germanys major public news website. It was reposted today on the occasion of the 30th anniversary of the disaster. Amongst others Dörte Siedentopf drew my attention to a 1959 agreement between the IAEA and the WHO.

Masterplan 10-82G

Ashes to ashes, dust to dust – remnants of the pub, as they are wafting over the railway tracks.

I am sorry to keep on talking about local politics. The pub from the last post has now been fully demolished. The little shops, which are adjacent to it are currently also under threat. A threat though of a slightly different sort.

Alert, Nunavut etc.

Saturday, November 28th, 2015

With some help from Tim and on the occasion of the 2015 United Nations Climate Change Conference I did a visualization which combines local temperatures with methane data. The local temperatures are from the HADCRUT4 file, so they unfortunately stop in 2011. The methane data is from the website of the Earth System Research Lab. Unfortunately there are not so many methane measurements as there should be. In particular very few temperature stations have also made methane measurements, so I improvised a bit and joined some measurement points which are geographically close. The measurements are from Vestmannaeyar, Iceland; Alert Nunavut, Canada; Svalbard, Norway with temperatures from Lufthavn and CH4 from Ny Ålesund; Syowa, Antarctica and from Azores, Portugal, where the temperatures are from Santa Maria Island and the methane data is from Terceira Island (if I interpreted the station names correctly).

I have currently not so much Internet time left, partly because I currently have a job, where I have to sit a lot in front of a computer and partly because I have been trying to improve things in my local surroundings (partially as it seems in vain though) – so no long explanations. I hope you see at least what I see in the images above.
