The cover shows a graphical representation of the structure of an example molecule of
hyperbranched polyethoxysiloxane having a polymerization degree of 45 and a degree of
branching of 49%. The frontcover image was generated with CORINA
(http://www2.chemie.uni-erlangen.de/software/corina/free_struct.html), PovChem w.chemicalgraphics.com/PovChem) and POV-Ray (http://www.povray.org).
„The chemists are a strange class of mortals, impelled by an almost maniacal
impulse to seek their pleasure amongst smoke and vapour, soot and flames,
poisons and poverty, yet amongst all these evils I seem to live so sweetly
that I wonder rather die than change places with the King of Persia.“
Johann Joachim Becher, Physica Subterranea (1667)
quoted in Paul Strathern, Mendeleyev´s Dream: The Quest for the Elements (2000)
