"Perfect symmetry" is a term that is too vague to use in scientific descriptions. I don't know what it means unless it refers to the sphere, which allows all possible symmetry operations. It's not that highly symmetric objects don't exist in nature, nor does it have anything to do with the second law of thermodynamics on a molecular level. "Perfect symmetry" as it relates to building lutes and other stringed instruments could be defined as belonging to the C1 point group (which is to say that the instrument is asymmetrical). To find higher symmetry, it is necessary to look at simpler instruments, such as a hand bell, which has C-infinty-v symmetry. When it comes to the physical construction of musical instrument, high symmetry means something relatively boring and the lowest symmetry possible is necessary to construct an instrument, such as a lute, that is designed to emphasize the different roles of the left and right hands, respectively.

However, has anyone read the book by Dr. Masaru Emoto, The hidden Messages in Water. Dr. Emoto, has found and photographed the formation of water crystals. Polluted water, or water subjected to negative thoughts, forms incomplete, asymmetrical patterns, with dull colors, and water from clear springs, exposed to positive thoughts forms brilliant complex, symmetrical, and colorful snowflake patterns. In Buddhist, and Hindu art, one finds perfect symmetry in the form of mandalas, which represent perfect Enlightenment. Is it wrong for humans to try to achieve perfect symmetry? It seems nature is trying.

It's a convenient and reasonably good approximation, but perfect symmetry runs afoul of the second law of thermodynamics, leading to things like point defects and dislocations. ----- Original Message ----- From: Michael Thames To: LUTELIST ; Manolo Laguillo Sent: Monday, May 23, 2005 10:34 AM Subject: Re: symm/asymm & perfect/imperfect >b.
