Science
Technology has always found its greatest consumer in a
nation's war and defense efforts. Since the last attempts at a
"Star Wars" defense system, has technology changed
considerably enough to make the latest Missile Defense
initiatives more successful? Can such an application of
science be successful? Is a militarized space inevitable,
necessary or impossible?

12553 of 12562) Can we do a better job of finding
truth? YES. Click "rshow55" for some things Lchic and I have
done and worked for on this thread.
Here's a K.I.S.S. level point I haven't gotten across well
enough:
. Most solutions that actually work in
exactly understood circumstances (such as many engineering
circumstances that are effectively modelled) can only be
modelled effectively using solutions that are
successive approximations - taken to more than
enough terms - taken to the point where further
refinement of the approximations makes no difference. Except
in special circumstances - this is a fact for basic and
inescapable reasons. People do not understand how often they
have to keep at it - and how often answers that have
been arrived at do not need to be abandoned - but need to be
refined. And compared to alternative systems of
explanation.
It is logically proper to "talk things to
death" - talk them to stability - and THEN summarize - with
matching to internal logic and circumstances carefully done
BEFORE the summary is undertaken.
That's how human discourse that actually works in practice
usually happens - if you go back and check.
. Be sure you're right. . . . . THEN
go ahead.
The long and the short of it is you need both long
and short. The long has to be right - and has to come first.
Leadership by "intuition" or "doctrine" -
without much more - is dangerous - essentially
certain to go wrong.
Our culture seems to believe in discussion - diversity -
but not to the point of convergence to clear answers. Ever.
The very idea of truth has been rejected - even by The New
York Times - and the rejection is doctrinaire and general.
In the 50's, very few "ordinary readers of The New York
Times" could have believed that such a thing could
happen in the United States.
I'll try to make that point about focus more completely -
comparing points made in The Boys Who Cried Wolfowitz
By BILL KELLER http://www.nytimes.com/2003/06/14/opinion/14KELL.html
and some points C.P. Snow made about the strengths and
weaknesses of Winston Churchill.
The connection to original work lchic and I have
done together - and partly written on this thread - is close.
It has to do with "connecting the dots" - and answers to both
the positive and the negative parts of Plato's problem as
General Eisenhower expressed it in condensed form to me:
How exactly can people be so smart?
and equally
How exactly can people be so stupid?
In workable, teachable detail.

Technical point:
Most solutions that actually work in exactly
understood circumstances (such as many engineering
circumstances that are effectively modelled) can only be
modelled effectively using solutions that are successive
approximations.
That's true in general, but the fact is hidden because
people change frames of reference to hide it in teaching - and
because many packages of successive approximation ( for
example, the functions defined by "infinite" series ) are
packaged and given names - so that details are hidden (and
often encoded in tables.)
People have a lot of beautiful, gem like "perfect examples"
where a single explanation "just fits" - but when you start
looking and counting - these are rare. That doesn't mean you
can't get perfectly satisfactory and "perfectly" valid
answers. It does mean that, quite often, a lot of work is
inescapable - especially before things focus.
After focusing, you sometimes can get perfect
answers - especially on things that are simple. Some of our
biggest technical problems are also simple.

The mechanical harvester & The Olive Tree
Tony Hawke's invention sprang from manually beating olive
trees with a fishing rod. He believes it will harvest other
crops such as macadamia, pistachio nuts, almonds, even citrus.
"Well we pinched the motor and the hydrostatics out a
cotton harvester and transplanted them into a chassis which is
this machine, then it all went from there, but in the future
we'd be putting new motors and new transmissions in the
machine," Tony Hawke said.
Hawke jokes that he sold a farm and now has a machine,
which owes him three quarters of a million dollars. This may
be a prototype and the improved version already on the drawing
board, but an inventor's lot is not easy.
"The rewards potentially are absolutely huge not just for
us, obviously for us but not just for us, but for the whole
industry," Adam Booker said.

Ye Oldie 'OLIVE' - the harvesting of, and best
auto-designs, are still problematic .... yet all assist in
keeping the price asked of the common-man, affordable.
