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?

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.
Sometimes faith is indispensible. But sometimes, on
practical things, faith is simply negligence . There
needs to be an obligation to check - and check competently,
when it matters enough. )
When soldiers are terrified, and bullets are rending
flesh, it ought to matter enough.
Some of the things that need to be understood and checked
may even involve mathematics - and experience.

"Some of the most unpleasant surprises of which nonlinear
control systems are capable are
1. divergent instability
2. limit cycles
3. multiple equilibrium points.
"and it needs to be continually borne in mind that, as far
as nonlinear machines are concerned, the behavior is
determined by the input-system combination. An understanding
of the conditions under which input-system combinations may
produce these surprises is facilitated by a parametric study
of the system . . . .
Chapter 10 of Analysis of Nonlinear Control Systems
by Dunstan Graham and Duane McRuer continues -
. In essence the summary is that if
nonlinearities are small enough - and if the system is well
understood enough, instabilities can be controlled within
tolerable limits for a particular set of circumstances -
limit cycles can be small enough to accept, and answers can
be close enough to fit well enough defined purposes.

I've worried about such things for a long time.
No doubt I come from a narrow and parochial background -
but there are some things that might be useful to
attend to.
We face some "unpleasant surprises" that ought to be
avoided - for reasons that ought not to be surprises. And we
are in a situation where the things that matter should
be able to sort out very well, from most human perspectives,
including my own, and I think, including Almarst's.
One thing is primordial. We have to understand the
situation we're actually dealing with - as it is - not as we
wish it to be.
A lot of the circumstances look pretty favorable, if we
face what we need to.
