A man can never give correct answer unless he will set some order in
the known objects of the
nature. The task of its classification is not new. There are many
methods to apply.
Using the ideas estalbished by Ampere and in the ancient Chana I try
too to set such classification on the base of the my model of the 4D
media: http://vps137.narod.ru/article4a.html.The model is needed to
develop but some results may be already obtained and presented at my
site
http://vps137.narod.ru/physics.html. Some of them is not translated
yet.
