Demystification of animal symmetry: symmetry is a response to mechanical forces

Symmetry of Fullerene C_60

a symmetry of power in michelangelo’s moses

among the various interpretations of michelangelo’s moses, freud’s is well-known. the founder of psychoanalysis, freud reviews all the critics and interpretations of this masterpiece and then offers his own: this moses is not about to spring up, as claimed by others, but on the contrary, is sitting down, suppressing his “rage”. in the light of recent works of daniel arasse, art critic (study of...

Charge Independence and Symmetry of Nuclear Forces

Charge independence and symmetry are approximate symmetries of nature. The observations of the small symmetry breaking effects and the consequences of those effects are reviewed. The effects of the mass difference between up and down quarks and the off shell dependence q 2 of ρ 0-ω mixing are stressed. In particular, I argue that models which predict a strong q 2 dependence of ρ 0-ω mixing seem...

A Discussion on Concept of Symmetry snd Asymmetry

This paper is concerned about the concept os asymmetry. The different types of asymmetry for univariate and multivariate distributions have introduces been considered as well as some of usual asymmetry criteria. A brief overview of method for adding the capability of modeling asymmetry to a symmetry distribution is also a secondary purpose of this paper.

A new paradigm for animal symmetry.

My aim in this article is to soften certain rigid concepts concerning the radial and bilateral symmetry of the animal body plan, and to offer a more flexible framework of thinking for them, based on recent understandings of how morphogenesis is regulated by the mosaically acting gene regulatory networks. Based on general principles of the genetic regulation of morphogenesis, it can be seen that...
