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

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

Friday, March 25th, 2016

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.

netzpolitik

Saturday, August 1st, 2015

I am quite shocked to hear that two bloggers from the blog netzpolitik, namely the here already mentioned Markus Beckedahl and the blogger André Meister were accused of treason for reports and the publication of some apparently classified information related to projects connected with a project called after the greek Perseus. The projects have amongst others a component which deals with the mass surveillance of social networks by german intelligence. Treason is to be punished with at least one year in jail if I understood correctly. I briefly read the various reports at netzpolitik (for time reasons in a rather diagonally manner) and I found nothing which could remotely justify such charges in my point of view. That is the presentations there describe a rough organistorial setup in which rather unspecified general tasks, like coordinization, consulting etc. are mentioned. The documents and reports thus give a very sketchy outline about the rough size and – in particular- costs of the projects (which seems to be rather of interest to the tax payer), but nothing really concrete.
The investigation is currently suspended and I hope that the charges will be dropped.
