Protein music

February 2nd, 2015

from wiki

In Gödel, Escher, Bach, Douglas Hofstadter draws similarities and analogies between genes and music.[1] It even proposes that meaning is constructed in protein and in music.[2]

The ideas that supports the possibility of creating harmonic musics using this method are:

  • The repetition process governs both the musical composition and the DNA sequence construction.[3]
  • Pink noise (the correlation structure “1/f spectra”) have been found in both musical signals and DNA sequences.[4]
  • Models with duplication and mutation operations, such as the “expansion-modification model” are able to generate sequences with 1/f spectra.[5]
  • When DNA sequences are converted to music, it sounds musical.[6][7]
  • Human Genome Project has revealed similar genetic themes not only between species, but also between proteins.[8]

Musical renditions of DNA and proteins is not only a music composition method, but also a technique for studying genetic sequences. Music is a way of representing sequential relationships in a type of informational string to which the human ear is keenly attuned. The analytic and educational potential of using music to represent genetic patterns has been recognized from secondary school to university level

last weekend I wrote few scripts to convert protein sequence to some attractive sounds.

sound track: “human protein 1”

Size of directory tree

February 14th, 2012

This is a simple script for Linux to check size of a directory and sub-directories :

1. check size of a current directory with sub-directories:

du –block-size=M  | sort  -n

2. check size of /home/user/alex directory with sub-directories:

du –block-size=M   /home/user/alex | sort  -n

3. check size of /home/user/alex directory with depth=2 sub-directories:

du –block-size=M  –max-depth=2  /home/user/alex | sort  -n
