Re: [Phys-l] teaching different descriptions of "reality"

[Jack Uretsky <jlu@hep.anl.gov>]

	I am not qualified to comment on his mental state, but he clearly
does not address concepts of modern physics in terms that I could discuss 
with any of my friends.
	He does seem to occupy himself with many misconceptions.  I note 
that he also addresses neurological issues, so he might be a doctor trying 
to dabble in physics.
