Reflections on the four facets of symmetry: how physics exemplifies rational thinking
In contemporary theoretical physics, the powerful notion of symmetry stands
for a web of intricate meanings among which I identify four clusters associated
with the notion of transformation, comprehension, invariance and projection.
While their interrelations are examined closely, these four facets of symmetry
are scrutinised one after the other in great detail. This decomposition allows
us to examine closely the multiple different roles symmetry plays in many
places in physics. Furthermore, some connections with others disciplines like
neurobiology, epistemology, cognitive sciences and, not least, philosophy are
proposed in an attempt to show that symmetry can be an organising principle
also in these fields
