Hello. I noticed something pecular about the diagram from the web site http://viswiz.imk.fraunhofer.de/~nikitin/vis99_imk/ [Broken]. The diagram that used to be below and can be found on the link above, shows the topography of "cusps" and string schematics and dynamics and has a certain resemblence to the major and minor grooves of a DNA molecule. I wonder if there is a physical property or law that leans toward the tendency to create these major and minor grooves.... I do believe the phenomenon (of major and minor grooves) is a function of log rythms and/or the golden ratio... 1 to 6. It seems to be a familiar and repeating pattern in nature... even on the scale of molecular structures... like DNA. Have a look! If you have an opinion on this, let me know, thank you.
