Re: "quantization"



Let me ask, without making no powerful reference (which is almost never a
problem), what is wrong in saying that energy is a physical entity which
conservation follows the time invariance of physics laws?

I think Noether's theorem's consequence is usually stated a bit
differently, but I understand that energy conservation is a
necessary counterpart (not a consequence) of the time invariance
of physical law. Let me also point out that energy conservation,
like energy itself, is a mathematical abstraction. The time
invariance of physical law is a quantitative statement as well.

The 'mathematical abstraction' of energy conservation is so firmly held in
established physical thought, that the neutrino was INVENTED to keep it so.
Many years passed before the neutrino was 'discovered', but it was well
accepted because it allowed us to keep holding to our ideas of energy (and
momentum) conservation.

Energy is so basic that we can, and will, invent 'nature' out of thin air
to retain it. Feynmann's discussion (in his 'Lectures' series) of a child's
blocks should be required reading.
