Science/TechnologyWorld's Most Expensive Substance by uchay1989(op): 11:58pm On Oct 30, 2014
In terms of production costs, the most expensive substance in the world is antimatter. The cost of creating this material has been estimated at about $1,771 trillion US Dollars (USD) per ounce ($62.5 trillion USD per gram), although some authorities think it may eventually come down to a mere $141.75 billion USD per ounce ($5 billion USD per gram). This is the cost of antihydrogen, the simplest form of this type of substance, and the antimatter equivalent of the element hydrogen. Other anti-elements would be even more expensive. As of 2013, only small numbers of antihydrogen atoms have been produced — for research purposes only — and the substance is not available for sale.
Why Antimatter is so Expensive

Antimatter consists of particles that can be considered the opposites of their normal matter counterparts. The matter people are familiar with is made up of atoms, which consist of a nucleus containing heavy, positively charged, particles called protons surrounded by a “cloud” of lightweight, negatively charged electrons. Atoms of antimatter have negatively charged antiprotons in the nucleus, with positively charged anti-electrons — normally called positrons — surrounding them. Although antiprotons have been detected in cosmic rays, and positrons are emitted by some radioactive elements, there is no known natural source of anti-atoms, so antimatter has to be manufactured.
Positrons can be obtained quite easily from materials that emit them, but the much heavier antiprotons have to be created in particle colliders — machines that send subatomic particles crashing into one another, and into other materials, at enormous speeds. These collisions concentrate tremendous amounts of energy into extremely small volumes of space, which results in the creation of matter in the form of particles and antiparticles, including antiprotons. These can be separated magnetically, and combined with positrons to make atoms of antihydrogen.

Since these anti-atoms can only be made at a handful of facilities, and only in tiny quantities, antihydrogen is extremely scarce. Not only is it difficult and costly to make, it is also difficult to trap and store. Anti-atoms are strongly attracted to normal atoms, due to electrons and positrons having opposite electrical charges, and when they meet, they annihilate one another, with all their mass turning into energy. Storage involves vacuum containers that keep the anti-atoms from touching the sides using magnetic fields. These factors combine to make antimatter the world’s most expensive substance.

Uses for Antimatter

Scientists would not go to the trouble of making this substance if it did not have some potential uses. Antimatter has the greatest energy density of any possible fuel, meaning that it has the potential to release more energy per unit weight than any other substance. Since it takes even more energy to produce antimatter than can be obtained from it, it is not a solution to the planet’s energy problems; however, it has been proposed as a possible future rocket fuel, as, in theory, it could accelerate a payload to a substantial fraction of the speed of light. For the moment, though, its main interest to scientists lies in what it can reveal about the laws of physics.

Other Expensive Substances

Still in the realm of exotic physics, nuclear isomers, although falling some way short of the world’s most expensive substance, would carry an extremely high price tag — possibly over $28 billion USD per ounce ($1 billion USD per gram). These are elements in which the atomic nucleus has more than its minimum amount of energy — the minimum being known as the “ground state.” In most cases, a nucleus in this “excited” state will revert to its ground state within a tiny fraction of a second, releasing energy in the form of gamma rays, but some nuclear isomers, such as hafnium-178m2 and tantalum-180m, are relatively stable and long-lived. Under normal circumstances, these isomers release energy slowly, as their nuclei revert randomly over a long period.

Experiments in the 1990s seemed to show that a sample of hafnium-178m2 could be triggered to revert to its ground state all at once, releasing large amounts of energy, by bombarding it with X-rays. This raised the possibility of using the isomer to store energy, or to develop new types of weapon. Attempts to reproduce the effect, however, have so far failed, and many scientists are very skeptical about these possibilities. As with antimatter, these substances need to be manufactured in expensive particle colliders, and are available only in tiny amounts.
RomanceWords From A Mother To A Daughter About Marriage by uchay1989(op): 11:52pm On Oct 30, 2014
1. The wife that wins all
arguments with her
husband is not wise. The home is not a law
court. 2. The wife that uses sex as a
weapon in the
home - placing embargo, going to bed in
jeans
shorts and trousers - lacks wisdom. 3. The
wife that uses the modern trends and
laws of "women's rights" to insult or
ridicule
her husband simply makes a fool of
herself. 4. A woman that makes her home
devoid of
peace through bickering, nagging and
quarrels needs help. A man should be
eager
to run away from office to be at home, for
that
should be the safest and coziest place on
earth for him. 5. Modern-day equality in
marriage does not
mean competition. It simply means
partnership. Taking advantage of such
equality to turn around and become the de
facto head of the home and oppress the
man
is tantamount to playing with fire. If you
destroy your home, soon you will be the
boss
of an empty home. 6. A wise wife makes
the man feel so good
that he assumes that he is the head. Once
he
gets that feeling, the woman gently wields
her
power and the head actually turns to
wherever
the neck wants without a protest. 7. A wife
that does not pull herself away from
friends' influence and advice or even from
the
control of her mother and father will have
herself to blame. 8. When a man is looking
for a wife, he
bypasses women of different shapes and
sizes to choose a wife. But soon after
childbirth, many women hide under the
excuse
of childbirth to let go of themselves. Many
stop
bothering about their looks, shape,
dressing, etc. Within 5 years of marriage,
people start
wondering if the wife is the man's aunt,
even
though she is 7 years younger.Her defence
is
that if he truly loves her, he should love her
the way she is.But when looking for a wife,
he
saw people like the present YOU and
ignored them and settled for the former
YOU. Today,
you go to bed smelling of onions.... You go
to
bed wearing grandmothers' clothes. Why
are
you playing with your marriage? Love is
not
about looks - we know. But looks enhance
love and marriage. There is a difference
between someone disfiguring herself and
the
person being disfigured by an accident.
Please don't be complacent.As hard as it
may
be, work on looking like you were when
he
first saw you and began the chase. 9. If
every night you are tired, sleepy, sore,
down with headache or fever, "not in the
mood," you are a joker, a serious
comedian! 10. If your children suddenly
become more
important to you than your husband, you
need
prayers. 11. If you assume that as the
woman, only you
need to be pampered and fussed over
while
the man is a stone that has no emotions,
you
need to be pitied. 12. A woman that has
the mind of a wife does
not excite her husband. Wives are usually
complacent and presumptuous. A wife
must
strive to have the mind of a girlfriend. A
girlfriend is always nicer, sweeter, more
loving
and always thinking of ways to wow her
sweetheart; a girlfriend does not try to win
all
arguments, does not call the man a
"useless
man", is not careless about her looks or
dressing, always smiles and laughs with
the
man, sends the man sweet messages and
calls, etc. Are you your husband's girlfriend
in word and
in deed?

Is it that Jonathan does not have N22million or are they just trying to portray him as a man loved by the people,moreover you did not state who made the donations
