On ''what there is''


The question looks ''philosophical'' in the sense of ''what exist?''. In the old terminology ''ontology question''.
The modern formulation (by Quine) is: ''what are the values of your variables''? In our hobby ''what are
the new available components''?  Can one person know what are available components? Obviously not
but we have ''collective knowledge''. Each contribution is welcome. Like in science. But like in science there
are individuals with special contributions. Raul with his MM contributions and his ''successor'' chakster
with his contributions about ''both kinds'': MC's and MM's. Despite his ''modest means''. I think we should
be thankful to have such individuals.

But there was not one single reaction about ''what cartridges there are'' but the most were critical remarks about my philosophical ''content''. 

Well MM, MC, Strain-Gauge, and the allegorical “Iron Cross” called MovIng Iron.
.....just another apprehended span of 'time' as we experience it in the quantum light show we refer to as the universe which individually doesn't 'start' until we're born, but 'ends' when we die.

In that 'meanwhile', Enjoy It.

At least, try. ;)

Good variable factors, Jerry
Nobody has ever mentioned Engels , Marx best friend, as
scientist. However he was the only one who stated that
''each discipline'' ( science) has its own philosophy. 
Everyone with an academic degree must know that in
his first semester (aka ''first year'') the so called ''subject
of study'' is learned as  ''introduction to...''
In this ''introduction'' are formulated basic assertions of
the science involved and those ''basic assertions'' or
''premise of the discipline involved''  can be seen as 
philosophy of this science. The curious thing is that such
''meta theory '' about own subject matter is learned in
the first year when students have no idea about their study.
The ''place'' of the ''meta theory'' should be placed in the
last year of the study when students ''got some idea''
about their study. Who can expect ''critical mind'' or ''critical
attitude '' by students in their first year of study? 

'Meta''-and ''object language''. We now know(?) that Frege
considered ''ordinary language'' as  not suitable for science
and try to ''invent'' an scientific language which is called
''new logic''. Less known is Tarski's attempt to avoid paradoxes
which origin when we speak in the same language about our
language. To avoid this ''difficulty'' he invented the separation
between ''object language'' and ''meta language'' the later
as being ''about'' object language. The problem is that we get,
say, many , or even worst, too many meta languages.
This is, uh, my introduction to ''meta theory'' as mentioned in
my previous post.
