Is this guy serious?
10 to 20 pounds of a cheap industrial explosive like TNT will take down a large house with out a problem and kill everyone inside.
He says something like that and thinks people will take his opinions seriously?
Yup, In a way computers SLOW down time.
Get up above a few billion operations/second and it’s like you have all the time in the world. :-)
Exactly, but if the trajectory changes due to any factor, or there isn’t enough time, it should miss. How can the early warning system calculate all those factors and intercept 90% of the time? It seems beyond remarkable. Maybe with multiple intercept points and ID missiles fired, I could see 90%. But they only fire 2 interceptors per rocket, correct? There are so many factors that can change the trajectory. Are the intercept points calculated on launch towards apogee, or after apogee? Or both? Is there enough time?
Burn time, wind, weight and time all factor into calculating the intercept. So if you got one wrong, then you would be making the best estimation. All of this has to be done by a computer, unless you have plenty of time. I imagine Israel doesn’t have much time from launch to impact.
Amen

Burn times for the Hamas rockets are short. By the time they reach apogee, they have already burnt out and are decelerating. My understanding is the Iron Dome only fires if the rocket's trajectory appears likely to strike a populated area. It doesn't need to vaporize its target either since knocking it off its initial trajectory will send it over less densely populated areas.
Exactly what set of criteria the Iron Dome uses I don't know but it doesn't seem all that difficult given the computational power available nowdays.
Why does it only work in Israel?
At least, this rate of successful intercept attempts.
Yea, I caught that too. What a absolute moron. No “professor” can HONESTLY be that stupid.
Okay, so he’s intentionally lying to deceive his readers.
The guy should be strapped to a 10 to 20 pound explosive package and see what happens. If he’s telling the truth, he should live. Since it’s not lethal. HIS WORDS, NOT MINE!
These are the people that are teaching our children, and lead our country. Liars, liars all of them.
Open heart surgery was considered undoable, and transplants unthinkable, but technology moved ahead at first with baby steps, then with giant leaps.
I think the same with Iron Drome... who cannot imagine that eventually it will be highly efficient system with lasers that zaps rockets out of the sky like fly swatters....
I see too, robots, like Gork, who will rule areas...
No one talks about this, but Iraq and Afghanistan has battle hardened our military. We fight, and what we’ve learned these years about fighting a war in the 21st century far and away outweighs the left, and some right-wing critics that say Iraq was a dumb war.
At least, this rate of successful intercept attempts.
It works only in Israel for much the same reason no one is willing to buy the Iron Dome... because no one else would tolerate the sort of attacks the Israelis put up with.
He knows it works and he's a Hamas sympathizer.........
One problem that Mr. Postal his is the Israeli BODY COUNT and associated destruction, unless he claims that nearly all 5,000 missiles simply fell on farmland.
Beyond that, trying to discount a 10 to 20 lb. warhead is like trying to discount a 10 to 20 lb. bomb. Yes, it’s not like the Oklahoma Bombing, but NO, you don’t want to be very close. If he wants, how about he have one detonated 200 feet from his (no doubt) very expensive home, and find out just what it can do.
Whada maroon!
I think he was blathering on and on with his point, which seemed to be that ID wasn’t successful at detonating/destroying the inbound *warhead* and that it was simply knocking them off trajectory, and allowing the still live warhead to fall, albeit not along it’s initial trajectory, and still detonate upon impact.
Well, maybe so... But in my stinky opinion, ID should still be credited with the intercept for knocking the inbound missile off it’s trajectory, even if it didn’t manage to destroy the warhead.
I do agree that early warning and shelters are vitally important, but I can’t blame the IDF for doing everything and anything to defend and defeat. The author seems to think that ID should be abandoned based solely on cost/benefit ratio. Well, perhaps the IDF is gathering the same data in order to improve ID. Nothing hones better than practice!
Yes...a math problem solved with high speed data processing.
We’ve been hitting missles with missles since the 1960’s, my father led the team that did it stationed in the Marshall islands.
Israel should agree with the “professor” and keep the technology, and the enormous advances in the technology in the past month, to themselves. Just keep thinking that about ID, professor Luddite.
We need a thread of all the works of God protecting Israel. This is how we glorify His Name among the nations and why Israel exists. How would I gather the info?
By the way, your post caused my monitor to get very blurry.
The press would would scream to all the world about how Israel’s ‘Iron Dome’ is a piece of crap. It would lead the nightly news on every channel. No major news corporation outside of FOX ever has anything positive to say about Israel. They are indifferent at best, openly hostile at worst.
Whenever you hear someone claim the liberal news media is covering for Israel you are listening to someone who is totally out of touch with reality. You are listening to someone who is utterly convinced the Jews run the world. This is the kind of person who, in another life, would support the theory that white people invented AIDS in a lab to kill black people.
A good conversation between you two a joy to read.
At this point I think it’s clear why it works in Israel and no where else: geographical location. Or proximity really.
That entire theater of operations is very small comparatively speaking. So I imagine the calculations needed to make such a system work so effectively there are simpler and more accurate in their predictions. In larger systems (such as intercepting ICBMs) I imagine the calculations and level of precision would be much greater. Too great to make it practical or reliable for our applications.
Think of it this way: it’s the classic case of launching probes to outer space. The longer the distance the greater even smaller error has an impact. This is because of distance. The greater the distance errors have a larger impact.
So in larger systems the smaller errors introduced by random variables such as the rocket fuel not burning as intended or wind speeds not as predicted, these errors compund and conspire against the success rate in larger systems. But in smaller, more localized systems these errors and variables become negligible enough that the two rockets can indeed be made to collide.
