Dear FIS colleagues,
Although I could not read M. Leyton's cited (2001) book :-( , I agree
with the principle of the nested hierarchy of symmetries.
I would like to rememeber, that I independently arrived to a similar idea
and proposed such hierarchy of symmetry breakings based on ontological
levels 5 years ago. I presented them at two Congresses in 1998, and both
papers have been published:
(1) 20th World Congress of Philosophy (Boston, 1998):
Darvas, G.
(1998) Ontological levels and symmetry breaking, Paideia, Philosophy
of Science,
http://www.bu.edu/wcp/Papers/Scie/ScieDarv.htm
(2) 4th Intnl. Symmetry Congress (Haifa, 1998)
Darvas, G.
(1998) Laws of symmetry breaking, Symmetry: Culture and Science,
9, 2-4, 119-127
Seemingly my hierarchy differs a little bit from Michael's, since my one
allows not only the emergence of new symmetries at a higher level, but
also points to the permanent loss of symmetries, that existed at the
lower levels.
As I showed at a conference on the problems of self-organising systems in
Wien in February 2003: in thermodynamic terms we do not use the same
reference frames, when we speak on the permanent loss of symmetry in the
evolution of matter on the one hand, and when we speak about the
increasing symmetry in a
closed physical system on the other hand.
The same concerns our entropy concept as well: we apply the same phrase
in different meaning, and this may cause confusions and
misinterpretations.
Without knowing the exact proofs applied in Michael's latest book, I can
base my opinion on the information persented in Tom Bearden's short
reference. This makes me to disagree with several far-reaching physical
consequences mentioned in his website communication.
Maybe I generate a new debate, but I think this theme worths.
