"ACK! THBBFT!"
Number the particles after deposition then add the checksum
afterwards.
Lay down a few gigacuries of reactor waste. Subsequent bomb
emplacement will be discouraged. US miltiary vehicles will enjoy a
smaller carbon footprint for not needing their headlights at night.
Kickbacks as carbon credit indulgences will finance the war against
Islam.

There may be other ways to get narrow band reflection. Sodium vapor will
reflect the sodium yellow lines.

What comes to mind is a powder duster that puts down stripes of
fluorescent powders, some in the UV that would show up under a UV lamp -
and if swept and relaid, would destroy the pattern.
This is not particularly cheap material but way cheaper than counter
measures to trucks and way way cheaper than taking care of the guys
losing their legs....

We can't do stuff like that anymore.
We're in a situation much like that guy in a _New Yorker_ cartoon.
He's in court and the judge, jury, witnesses and lawyers are all
women. He's hanging his head in shame and the judge leans over and
asks him, "why won't you cuddle?"

It would be preferable if they couldn't detect it.
That way they would never know if we had been dusting the entrances of
their caves.

I was hoping for something that would show up clearly on satellite
images or at least air photos as well as the ground.
Even better would be a meterial that was nearly impossible to see with
any low tech sensor, something hard to see in the IR, visible or UV
wavelengths, indeed
The right sensor / material processing strategy might open the door
for a commodity material and change the nature of these types of
conflicts.
Glass beads with some precise diffraction grating could be cheap to
produce in bulk yet nearly impossible to counterfeit.
If each particle was 300 microns diameter distributed on a 1 cm X 1 cm
grid then one m^3 -- maybe a ton or so -- would do somewhat less than
50 km X 10 m or 30 miles of 30' wide road.

Someone suggested that just the random distribution would be good
enough, impossible to replicate on the ground.
That's probably correct.

DoD Secretary Gates said they were looking for a solution.
If the material cost $1,000/ ton and 50 tons could keep 1,000 miles
safe, that's just $50/mile, much cheaper than pavement.
And they wouldn't know if their caves had been dusted.

Interesting concept, but I don't see the need for patterning: if most of
road is "dusty" and fluoresces, but there's a non-fluorescing "dark
hole", that could strongly suggest digging.
And if the powder can be, not dusted, but sprayed in a fast evaporating
liquid, it may be more sticky and resistant to sweeping.
However, the real weak point may be the countermeasure: just tunnel in
from the side, from a starting point 5 or 10 feet out in the bushes, and
plant your bomb a few feet under the road surface (which remains totally
undisturbed).

Especially if it would seep down a couple of inches. Something with a
low surface tension and low viscosity like WD-40.

That would also be true for paved roads, a much more expensive
solution.
If the material is cheap enough, say a few thousand dollars/ton, it
would be cost effective to widen the safety zone and force them to
tunnel a hundred feet or more.
They would need to haul out the dirt and spread it somewhere where it
wouldn't cover any of the material or be visible to the naked eye.
Depending on the necessary depth of the bomb, it might be tricky for
low tech to get close enough to the surface without the tunnel
collapsing.
The Navy spent several hundred thousand dollars trying to figure out
how pelicans see fish at oblique angles. Obviously a pelican doesn't
directly see the fish, at least not at first. The index of refraction
of water is too great This works for the pelican because the fish
doesn't see the pelican either.
The pelican must be able to see the tiny deflection a fish makes on
the surface of the water. The pelican knows there's food down there
somewhere and rapidly picks up speed. By the time the fish becomes
visible to the pelican -- and the pelican to the fish -- it's too late
for the fish. The pelican has already built up so much speed all it
needs to do is make minor adjustments by looking directly at the fish.
Any sensor/material tracking system found in Nature can be beaten by
high tech optics and electronics.
One pico gram of some organic tracking chemical put down by ants can
be spread over thousands of miles, the transmission of which is
entirely by mass transfer.

I believe that my topic is useful and I would like to share my
thoughts.
THANK YOU.
Merits of Islam in Public Rights
1- Islam prohibits encroachment on the creatures of God, whether
they are humans, animals or plants.2:190. And fight in the Way of
Allâh those who fight you, but transgress not the limits. Truly, Allâh
likes not the transgressors.The Prophet (peace and blessings of Allah
be upon him) said: “A woman was punished because of a cat which she
detained until it died of starvation, because she neither fed it, nor
let it free to eat from the vermin of the earth.” The Messenger of
Allah (peace and blessings of Allah be upon him) said: ‘Whilst a dog
was walking around a well, almost dying of thirst, one of the
prostitutes of Bani Israa’eel saw him, took off her shoe, filled it
with water and gave him the water. She was forgiven because of that.”
Muslim armies were ordered not to kill anyone who was not fighting
them, like women, children, the elderly and the priests. They were
ordered not to cut trees and not to fill up water wells with dirt.
2- A Muslim must be like a candle illuminating the way for the people
for the straight path to be saved them from God’s fire. 3: 110. You
[true believers in Islâmic Monotheism, and real followers of Prophet
Muhammad and his Sunnah (legal ways, etc.)] are the best of peoples
ever raised up for mankind; you enjoin Al-Ma’rûf (i.e. Islâmic
Monotheism and all that Islâm has ordained) and forbid Al-Munkar
(polytheism, disbelief and all that Islâm has forbidden), and you
believe in Allâh. And had the people of the Scripture (Jews and
Christians) believed, it would have been better for them; among them
are some who have faith, but most of them are Al-Fâsiqûn (disobedient
to Allâh – and rebellious against Allâh’s Command).
3- Islam calls for social cooperation and giving the rights to those
who deserve them by paying alms and charity.51: 19. And in their
properties there was the right of the beggar, and the Mahrûm (the poor
who does not ask the others) , 9:60. As-Sadaqât (here it means Zakât/
alms) are only for the Fuqarâ’ (poor), and Al-Masâkin (the poor) and
those employed to collect (the funds); and for to attract the hearts
of those who have been inclined (towards Islâm); and to free the
captives; and for those in debt; and for Allâh’s Cause (i.e. for
Mujâhidûn – those fighting in the holy wars), and for the wayfarer (a
traveller who is cut off from everything); a duty imposed by Allâh.
And Allâh is All-Knower, All-Wise. 17:28. And if you (O Muhammad) turn
away from them (kindred, poor, wayfarer, etc. whom We have ordered you
to give their rights, but if you have no money at the time they ask
you for it) and you are awaiting a mercy from your Lord for which you
hope, then, speak unto them a soft kind word (i.e. Allâh will give me
and I shall give you).
4- Islam orders compassion and charity to the poor, the needy, the
relatives, the neighbors and the wayfarers.4: 36. Worship Allâh and
join none with Him in worship, and do good to parents, kinsfolk,
orphans, Al-Masâkin (the poor), the neighbour who is near of kin, the
neighbour who is a stranger, the companion by your side, the wayfarer
(you meet), and those (slaves) whom your right hands possess. Verily,
Allâh does not like such as are proud and boastful;
5- Islam imposes fasting the whole month of Ramadan to make Muslims
experience the poor people’s deprivation, therefore sympathize with
them by giving them charity.2:183. O you who believe! Observing As-
Saum (the fasting) is prescribed for you as it was prescribed for
those before you, that you may become Al-Muttaqûn (the pious).
6- Islam warns against taking money from the orphans, or spending it
needlessly.4: 2.And give unto orphans their property and do not
exchange (your) bad things for (their) good ones; and devour not their
substance (by adding it) to your substance. Surely, this is a great
sin. 6:152. "And come not near to the orphan’s property, except to
improve it, until he (or she) attains the age of full strength; and
give full measure and full weight with justice. We burden not any
person, but that which he can bear. And whenever you give your word
(i.e. judge between men or give evidence, etc.), say the truth even if
a near relative is concerned, and fulfill the Covenant of Allâh, This
He commands you, that you may remember.
7- Wealth is a gift from Allah, none has the right to feel superior to
others because they are wealthier than them, so Islam calls for
treating the rich and the poor in the same manner.80: 1.The Prophet
(peace and blessings of Allah be upon him) frowned and turned away,2.
Because there came to him the blind man (i.e. ‘Abdullâh bin Umm-
Maktûm, who came to the Prophet (peace and blessings of Allah be upon
him) while he was preaching to one or some of the Quraish chiefs).3.
But what could tell you that per chance he might become pure (from
sins)?

that he has put out. Of all of the things he treasures most is the "peace"
that comes from death and deestruction. Yes, Islam is indeed the religion
of death and the peace derived from shuch.
Go away and stop bothering me! You yourslef have proven you are inteerested
in death and destruction by the very words you just posted in a response to
a serious post by me.

I would be thankful if you give my article 5 minute of your value
time. THANK YOU.
Equality Between Men and Women in Islam
Islam establishes the principle of equality between men and women in
all aspects of life that they are equal in, because both of them are
equally human. It does however distinguishes between them in some
areas, taking into consideration the natural differences between them
and the special qualities that each of them has.
Equality between men and women in Islam is derived from the following
considerations:
1. Equality in their human origins: Islam conclusively establishes
that all human beings have a common origin. This fact is mentioned in
many verses of the Qur’ân:
- O Mankind, fear your Lord who created you from a single soul and
created from it its mate and brought forth from the two of them many
men and women.
- O Mankind, verily we created you from a male and a female and made
you into nations and tribes so you may know one another. Verily the
most honorable of you with Allah are the most righteous.
2. Equality in their common destiny:
Islam also establishes that all of mankind is going to return to Allah
who created them, and everyone – male and female – is going to be
recompensed for his or her worldly deeds. They will receive well if
they did good and they will be requited with evil if they did evil.
Allah says:
- And every one of you will come to Him alone on the Day of
Resurrection.
- A human being will have nothing except for what he does. And his
deeds will be seen. Then he will be recompensed fully.
- So their Lord accepted of them their supplication and answered them:
‘I will never allow the work of any of you to be lost, male or female.
You are from each other.
- Whoever works righteousness as a believer, whether male or female,
we will truly give a good life and We shall pay them a reward in
proportion to the best of what they used to do.
