Re: [Yasmin_discussions] artists and atoms: fission and fusion

Thank you Jean-Pierre and others for tasty posts

a few things, concerning the phsysics music relation in the last few decades i think it is important to underline the importance of operational frequency domain analysis which became available analaogically by the begining of the century and digitally with the early fft algorithms in the 70s.

in fact this has to do with time , as long as time was basically measured by mechanical devices the limit, given by the inertia in the parts of the machine that need to run faster and faster to reach small time intervals, at some speed any attached mechanical device breaks under inertial forces, so when mass got out of the way with elecronics and temporal patterns could be produced without involving inertial forces several orders of magnitude in time detail where made available to analyze and syntetize (eg the oscilloscope)

this gave frequency domain analysis where time is understood both as a monotonically increasing variable (time domain) and as a frequency domain structure or process where multiple frequencies of different amplitudes and phases coexist.

obvioulsy physicists and mathematicians enjoy playing with these things

then in computertimes, a major breackthorugh came in the late 1960s and early 1970s when applied mathematians (watts and jenkins etc) working on time series analysis published the code of fast fourrier transforms that could be run in any computer, a few years later real time spectral analysis and synthesis of sound could be done

I visited IRCAM in the mid 1970s many times and had good friends there, one day i was shown the rack of circuits that they were developing and later became MAC4 and the whole geneaolgy of programmed sound poetry

the newly developed circuits where securized with a crossing fine rope tied in the mdiddle and sealed with red laquer, just as a 17th century document would have been

so at some point sound and time could be dealt with in the frequency domain not by using scores but by modulating digital and then analogical oscillations of electromagnetic fields and hydraulic presure, over a vast range of frequencies and periods, much beyond the 20 Hz to 20 kHz where we do that in sound perception or the 400nm 700nm range where we see colours

all of this is a good example of the interplay between collective, abstract understanding of things and the constroction of functional signals, material perturbations that do things, making inventions out of fictions as was said in a previous discussion here


and to close this just a note on the experiments with sound on water reported some years ago that managed to implode air bubles with huge sound pressure waves in a way thet the energy concentrating as the bubble dimished increased vastly and at some points seemed to produce fusion conditions, it did not seem a very practical way of doing it but as far as i could see it was plausible
