answer:@Dan_Lyons Welcome to the collective. True, there is an art to science, and there is usually a science to art. In your example, “out pops a David or Pieta.” There are usually many more pieces of marble that started out to be the sculptures. I;m a musician, and I know very well how the interaction of certain frequencies produces chords, and to a certain extent, I know why certain sounds “sound” pleasing to the ear, or not. I also know there is a science and art to building instruments. I also know that after 400 years, science and art combined have still not been able to reproduce a Stradivarius violin (my best guess is the glue!)
