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.

Friedhof Heiligensee

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.

Employment to population ratio

Wednesday, July 23rd, 2014

I am still collecting data on global employment in order to better investigate the replacement of human work by machines. Unfortunately it turned out that the International Labour Organisation (ILO), which holds most of the original data restructured their IT-sector. This means in particular that some older data can’t be reproduced any more. Above you can see that the worldwide employment went down on average since the nineties. I keep the data now here locally on our account as a copy from ILO in order to keep the findings reproducible. The data source as well as the source code for extracting it (GPL) are here. As always: if you spot some mistakes please let me know.
