A new video of one of Tims recent music projects (a video about the ladder filter is here). In the video he explains the construction of a spring reverb:

A detailed description on how to build the spring reverb can be found on the astlab page.

A soundtrack on soundcloud of how the spring reverb sounds:

Tim and a bit of his music projects will eventually appear in a new film by film maker Ekaterina Eremenko. That is we had a film team from Moscow here at home. But it is sofar not clear wether the material will be used.

Ekaterina Eremenko, who has also studied math, received recently much attention for her film colours of math (trailer) featuring amongst others the rather well-known mathematicians Cedric Villani, Anatoly Fomenko, Aaditya V. Rangan, Günter Ziegler, Maxim Kontsevitch and Jean-Michel Bismut.

I don’t know if this is a new trend but I found incidentally more recent films where features of the life of mathematicians are documented. Like at the website of the “Higher Algebra section” at Moscow State University I found interviews with V. N. Latyshev talking About academic mathematics (in russian) and about Reminiscences of A. A. Markov (in russian) made by Andrei Verovkin who features a whole series of interviews with scientists.

In this context a short note for those who are in or are planning to go to visit Berlin: There were/are currently music festivals for more modern music taking place in Berlin, which enhance the usual club life or on the more classical level regular events like e.g. the weekly series “Unerhörte Musik im BKA”. One was the Ultraschall Festival and one is the ctm festival, which is in cooperation with the festival for art and digital culture “transmediale”. The transmediale theme of this year is “afterglow:”

The conference takes afterglow as a metaphor for the present condition of digital culture, examining the geopolitical, infrastructural and bodily consequences of the excessive digitisation that has taken place over the course of the last three decades.

For those who are interested there is a discussion about determinism and freedom, free will, privacy etc. at the blog backreaction following a post with the title: 10 Misconceptions about free will, which I found problematic. If you want to know more you may read my comment also after the klick.

randform wishes all it’s readers happy holidays and a good new year 2014!

We preferred to stay in the outskirts of Berlin on New Years Eve. Even in the outskirts there is still enough fireworks. An aquaintance of us lost a couple of years one eye by just walking on new years eve on a street. If you still want to experience new years eve in Berlin then since there are no noise barriers and roofs against rockets and bangers on the street then our advise is to at least use some hearing protectors if that doesn’t give you too much head aches and safety glasses when moving around on the streets of Berlin on that time of the year.
