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.
Sorry to be late. Was just about to file this:
Commondata , I'll be tomorrow morning before I can
answer you. I lost track of time.
Hitting a target with a bullet , angles are
critical, and knowledge of range, drift, etc is critical, but
time isn't critical.
To hit a bullet with a bullet , time
That's a big reason why missile defense is so difficult.
You can't lose track of time. Collision has to be timed - and
timed within less time than it takes to blink an eye.
Another reason missile defense is hard is that the "target"
you have to hit in space-time has to be calculated - - when
you're shooting at the target, it is a point in empty space.
And calculating that point in empty space takes precise data,
And good math, done accurately and quickly.
Getting both the data and the math has been hard.
Science writing is hard, too. I've spent some time
wondering how to explain what I need to explain to a big
league baseball player or coach, or to a soccar fan, or to a
cricket fan, or to a racing fan interested enough, and
knowledgable enough, to actually buy a ticket and watch. Or
somebody who can actually hit a target with a gun in a
competitive way - or shoot skeet - or go bird hunting and not
come home empty-handed.
Those standards are high standards. Hard to satisfy.
Wish I had a copy of Ted Williams book on hitting a
baseball handy. Ted Williams had an exquisite sense about the
kinds of physical problems that make the "game" of missile
defense hard, and could put them in plain language. Plain
language is important - especially since "missile defense" is
a "game" that is played "for keeps." Which means it is no fun
at all - and interdiction looks good in comparison.
Wish I knew more about cricket.
Wish I was a little clearer about how you explain calculus,
comfortably, in plain english.
Anyway, I did keep another promise, and made some banana
bread. I'll be back in the morning.

"Quae cum ita sunt" Caesar's Gallic
It appears that hitting an artillery shell with a laser
beam is a piece of cake.
Once again Robert doesn't know what he's talking about.
During the Korean war the first Ground Control Approach, (GCA)
systems were deployed for guiding aircraft to a safe landing,
(see the movie "The High and the Mighty"). GCA controllers
noticed that whenever the base came under mortar attack they
could see the incoming rounds. This was reported and it didn't
take long for the Army to spec, developed and deploy a Counter
Battery System which could identify and incoming round, do a
calculation of the ballistic path and feed targeting
information to US mortar crews. It was reported that before
the first incoming mortar round struck the responding US
mortar round was already on its way! Excuse me but solving
those "mathematical situations" were the basis for and first
use of ENIAC the first computer! Hitting a bullet with a
"photon bullet" was demonstrated today by the Army.
Differential equations? Give me a break!

Saw a docco on the Korean War ... the Yanks just killed
'everybody' ... couldn't tell the difference between
civillians and enemy and in fact may have had orders just to
KILL KILL KILL .. that's why the folks from those campaigns
prefer NOT to remember ... Gunner's Block!
