What’s going on in Fukushima?

Some remarks on the recent observations regarding plant 2.

xOSC keygloves

Sunday, December 4th, 2016

In the randform post “Gesture steered Turing machine” I used data gloves, which were made following the instructions of Hannah Perner-Wilson who is a member of the gloves project. Being weary of sitting too much at the computer I had also written in this post that I would like to make more use of body movements and in particular include danse-like movements in computer interaction and in particular in programming.

Unfortunately rather shortly after I had written the post a not so nice medical indication in my vicinity which was -at least partially- due to too much computer sitting urged me to more or less dramatically speed up this project.

The gesture recognition for my gloves, which were used in the Turing machine example, works, but it is not yet fine grained and exhaustive enough. So I had to look for an easy and fast and at least to some extend workable and affordable solution which would insure a more direct and precise steering possibility, like some version of key gloves. To make it short: In the end I made my own version with Tims help. Again it’s only a start but still.

radio technology museum Königs-Wusterhausen, part 2, the Dieselgenerator

Saturday, November 19th, 2016

There was a bit of discussion going on about the last image in the last post which displays two emergency switches on a wall in the radio museum. On the switches there were the words “Diesel” and “Schaltfeld (switch board).” Above the switches there were two signs, each with the message: “Es darf nur eine Laufkatze betrieben werden” (There musn’t be more than one hoist in operation”). I was guessing that “Diesel” meant eventually the Diesel generator within the museum building which served -if I understood correctly- mainly as an emergency power system. So here now images from the Diesel generator.

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.

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.

Gesture Steered Turing Machines

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.

Commemorating the Chernobyl disaster

Tuesday, April 26th, 2016

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.
