A Hail Stone is not a stone at all but a small stone of ice. It start it's life from a thundercloud as a tiny ball of snow. The ball is tosed up and down in the cloud so often that it gets coated with layers of ice, like a layer of an onion. Eventually these ice skips , and come down to earth as a Hail Stone.

A MESENGER REMEMBERED
You have all heard about marathon race, in which the participant run across very long distance. The game was first held to honour the memory of ancient Greek soldier, who made a heroic long distance run just to communicate a message. It happened in B.C. 490. In that year Greece fought with Persia were miraculously defeated by the comparatively Greek army. A Greek soldier named Pheidippider was sent from Marathon to Athens to announce the victory. It is said that he ran the entire distance of 40km with out stopping, but moments after proclaiming his message to city he collapsed dead, from exhaustion.
Animals behave before rain
Animals behave in different ways before it start to rain. Here are some such behaviours.
- Bats fly lover.
- Frogs emerge from the water croaking.
- Wolves howl.
- Birgs sing more.
- Cattle gather close together.
- Roosters crow before retiring to sleep.
- Fish take baith more egerly.
DIGETAL PAPER
Digital paper is an mind blowing invention for future communication. It looks and feels like ordinary paper, but it is made up of millions of microscopic minicomputers. Which can communicate with a world wide communication net work, change colour, display different pictures at different times, and even act as a speaker.
Digital paper will interact with you. It can recognise your hand writing, and understand what you say. it can even folded up and put it in your pocket.

Born To Rule.
An ancient civilisation that flourished in Mesopotamia which lies in modern day Iraq, practiced a strange rule to please the God During New Year or during troubled times, the people of Mesopotamia scarified their life of there king to satisfy their deities. In real fact, the actual king was given the day off, and a helpless commoner was sworn king for the day, just so he could be scarified. In 1861 B.C., Entail Bani was the king substitute. But incredibly just as he was about to hung, a breathless messenger arrived with news that the real king had died! Entail Bani was saved and subsequently, ruled Mesopotamia for twenty four years!
DA VINCI CODE
The artist and scientist Leonardo DA Vince made
thousends of drawing and observation in his note
books, but his note appears to be made in a secret
code, DA Vince was left handed and his writing goes
right to left. It can be read properly if held up in

Saved By April Fool's Day.
In 1634, Nicolas Francois and his wife, Claude, the Duke and Duchess of Lorraine in France, were sentenced to death. They were imposed in their palace at Nancy.On April 1,they escaped from to freedom by climbing out of a window.Then they swam across the river Marthe to safety Witnesses WHO saw them shouted, to alert the guards, but the guards did nothing! They thought it was just an elaborate April Fool's joke!

MAGNATIC FIELD
Region arount a magnet,electric current or changing electric field in which current is stationary, while that arount an alternating curret or changing direct current is continuously changing. Magnatic field are commonly reprecented by continuous lines of force or magnatic flux that emerge from north-seeking magnetic poles and enter south-seeking poles. The dencity of the lines indicate the magnitude of the field, the lines being crowded together the magnatic field is strong. The SI unit of Magnatic flux is the weber.

Giant Pandas
The giant pandas that live in the different parts of china are for the most part they are vegeterian.They eat mostly bamboo shoots. However,they may,very rarely eat small animals like mice. This may be because the bamboo forests are being destroyed, and with this destruction, their main food source is disappering.
The Cat Famly
The cat family has about 38 species ranging from the giant siberian tiger to domestic cats.The seven big cats are tiger,lion,leopard,snow leopard,clouded leopard,jaguar and cheetah.
Giant Pandas
Giant pandas li in the conficious forests of china.Where there is a thickundergrowth of bamoo.They are found elevations between 1500m and 3000m.th favourite food of pandas are bamboo leaves.
This unique bear has long been revered by the chineese.It is a national treasure in chinaand is therefore,protected by law.

Amazing Antartica
Antarctica is the coldest place on earth.It's
freezing air tends to be extremely dry because
very cold air holds only a small amount of
water vapour
Beneficial Effects of UV radiation
A positive effect of UVB exposure is that it induces the production of vitamin D, in the skin. It has been estimated that tens of thousands of premature deaths occur in the United States annually from a range of cancers due to vitamin D deficiency. Another effect of vitamin D deficiency is osteomalacia (the adult equivalent of rickets), which can result in bone pain, difficulty in weight bearing and sometimes fractures. Other studies show most people get adequate Vitamin D through food and incidental exposure.
Many countries have fortified certain foods with Vitamin D to prevent deficiency. Eating fortified foods or taking a dietary supplement pill is usually preferred to UVB exposure, due to the increased risk of skin cancer from UV radiation.
Ultraviolet radiation has other medical applications, in the treatment of skin conditions such as psoriasis and vitiligo. UVA radiation can be used in conjunction with psoralens (PUVA treatment). UVB radiation is rarely used in conjunction with psoralens. In cases of psoriasis and vitiligo, UV light with wavelength of 311 nm is most effective.

UVB radiation is rarely used in conjunction with psoralens. In cases of psoriasis and vitiligo, UV light with wavelength of 311 nm is most effective.
Ozone Deplection
Ozone depletion describes two distinct, but related observations: a slow, steady decline of about 4 percent per decade in the total amount of ozone in Earth's stratosphere since around 1980; and a much larger, but seasonal, decrease in stratospheric ozone over Earth's polar regions during the same period. The latter phenomenon is commonly referred to as the ozone hole.
In addition to this well-known stratospheric ozone depletion, there are also tropospheric ozone depletion events, which occur near the surface in polar regions during spring.
The detailed mechanism by which the polar ozone holes form is different from that for the mid-latitude thinning, but the most important process in both trends is catalytic destruction of ozone by atomic chlorine and bromine.[1] The main source of these halogen atoms in the stratosphere is photodissociation of chlorofluorocarbon (CFC) compounds, commonly called freons, and of bromofluorocarbon compounds known as halons. These compounds are transported into the stratosphere after being emitted at the surface. Both ozone depletion mechanisms strengthened as emissions of CFCs and halons increased.
CFCs, halons and other contributory substances are commonly referred to as ozone-depleting substances (ODS). Since the ozone layer prevents most harmful UVB wavelengths (270–315 nm) of ultraviolet light (UV light) from passing through the Earth's atmosphere, observed and projected decreases in ozone have generated worldwide concern leading to adoption of the Montreal Protocol banning the production of CFCs and halons as well as related ozone depleting chemicals such as carbon tetrachloride and trichloroethane. It is suspected that a variety of biological consequences such as increases in skin cancer, damage to plants, and reduction of plankton populations in the ocean's photic zone may result from the increased UV exposure due to ozone depletion.

Global waming
The term "global warming" is a specific example of the broader termclimate change, which can also refer to global cooling. In common usage the term refers to recent warming and implies a human influence.[6] The United Nations Framework Convention on Climate Change (UNFCCC) uses the term "climate change" for human-caused change, and "climate variability" for other changes.[7] The term "anthropogenic global warming" is sometimes used when focusing on human-induced changes.
Earth's climate changes in response to external forcing, including variations in its orbit around the sun (orbital forcing),[8][9][10] volcanic eruptions, and atmospheric greenhouse gas concentrations. The detailed causes of the recent warming remain an active field of research, but the scientific consensus[11] identifies elevated levels of greenhouse gases due to human activity as the main influence. This attribution is clearest for the most recent 50 years, for which the most detailed data are available. In contrast to the scientific consensus that recent warming is mainly attributable to elevated levels of greenhouse gases, other hypotheses have been suggested to explain the observed increase in mean global temperature. One such hypothesis proposes that warming may be the result of variations in solar activity.[12][13][14][15]
None of the effects of forcing are instantaneous. The thermal inertia of the Earth's oceans and slow responses of other indirect effects mean that the Earth's current climate is not in equilibrium with the forcing imposed. Climate commitment studies indicate that even if greenhouse gases were stabilized at 2000 levels, a further warming of about 0.5 °C (0.9 °F) would still occur.[16]

RAINBOW
Series of concentric, coloured arc that may be see when light from a distant soure-usually the sun-falls on a collection of water droups such as in rain, spray or fog. The colered ray of the rain bow are caused by the refraction and total intanel raflection of light ray that enters the drop,each colour beeing bend through slightly different angle.Hence yhe different colours are spread upon emerging from the droup.The most brilliant and most common rainbow is the so-called rainbow,which results from light that emerges from the drop after one internal reflection.The colour of the arc (from outside to inside) red,orange,yellow,green,blue,indigo and violet. Occationaly a less-intese secotary bow may be observed;it has its colour sequence reversed.

Nuclear energy
Nuclear energy was first discovered accidentally by French physicist Henri Becquerel in 1896, when he found that photographic plates stored in the dark near uranium were blackened like X-ray plates, which had been just recently discovered at the time.[1]
Nuclear chemistry can be used as a form of alchemy to turn lead into gold or change any atom to any other atom (albeit through many steps).[2] Isotope production often involves irradiation of another isotope with alpha rays, beta rays, or gamma rays.
Iron has the highest binding energy per nucleon of any atom. If an atom of lower average binding energy is changed into an atom of higher average binding energy, energy is given off. The chart shows that fusion of hydrogen, the combination to form heavier atoms, releases energy, as does fission of uranium, the breaking up of a larger nucleus into smaller parts. Stability varies between isotopes: the isotope U235 is much less stable than the more common U238.

New Horizons from NASA
New Horizons is a NASA unmanned spacecraft designed to fly by Pluto and its moons (including Charon) and transmit images and data back to Earth. Mission planners hope that NASA will approve plans to continue the mission with a fly-by of a Kuiper Belt Object and return further data. A consortium of organizations, led by Southwest Research Institute and the Johns Hopkins Applied Physics Laboratory, has built the craft. The mission's principal investigator is S. Alan Stern of Southwest Research. The probe successfully launched from Cape Canaveral, Florida at 14:00 EST January 19, 2006 and is now en route to Jupiter for a gravity assist.
The primary scientific objectives are to characterize the global geology and morphology and map the surface composition of Pluto and Charon, and study the neutral atmosphere of Pluto and its escape rate. Other objectives include studying time variability of Pluto's surface and atmosphere; imaging and mapping areas of Pluto and Charon at high-resolution; characterizing Pluto's upper atmosphere, ionosphere, and energetic particle environment; searching for an atmosphere around Charon; refining bulk parameters of Pluto and Charon; and searching for additional satellites and rings.

AMAZING ANTARTICA
Antartica is coldest place on earth. It's freezng air tends to be extermily dry because very cold air holds only a small amount of water vapour.
GREEN HOUSE EFFECT
Warming of Earth's surface and lover atmosphere that tends to intencify with an increase in atmospheric carbon dioxide and certain other gases. Visible light from the sun,heat the Earth's surface. Part of energy is reradiated in the form of long -wave Infrared Rdiations, much of hich is aborded by molecules of crbon dioxide and water vapour in the atmosphere and reradiated back towards the surface as more heat.
This process is analogous to the glass panes of green house that transmit sun light but hold heat. the trapping of nfrared radiations causes the Earth's surface and love atmosphere to warm more than they otherwase would,making the surface haitable. the increase in atmospheric carbon dioxide caused by widespread combustion of fossil fuels may intencify the greenhouse effect and cause long-term climtic change.
An increase in atmospheic concentractions of other trace gases such as chloroflurocarbon, nitrous oxide and methane may also aggravate green house condetions. It is estimatd that since the begening of ndustrial revolution the amount of atmospheric carbon dioxide has incresed 30%, while the amount of methane has doubled. Today the U.S. is responsible for about one fifty of all human produced greenhouse gas emmission.

BALOON SELLER
There wasa man who made his lives with sellins baloons at a fair. he had baloons of so many colour like green, red, blue,black etc...Whenever business was slow,he would release a hydrogen balooninto the air.When the children saw the baloon go up,they all wanded one.They would come up to him,buy a baloon and his sales would go up. All day, he continued to release a baloon When ever the sales slowed down. One day, the baloon man felt someone tygging at his poket. he turned around and a little boy asked,"If you release a black baloon,would that also fly?" The man replied gently,"Son, it is not the colour of the baloon,it's what inside that make it go up.
PRIEST AND FARMER
A priest was driving,when he saw an exceptionally beautiful farm he stoped at the edge of the field,got out,and stood quietly,appreciating bountifulcrop. The farmer was riding on his tractor and saw the preist. Priest said to farmer,"God has bless you with a beautiful farm.You should be greatfull for it..Farmer replied that,"God has bless me with a beautiful farm.I'm be greatfull for it,but you should have seen this farm when god had the whole farm to himself."
DRONA AND ARJUNA
An ancient Indian sage named Dronacharya was teaching his disciples the art of archery. Heput a wooden bird at the target and asked his disciple to aim at the eye of the bird. The first disciple was asked what he saw. He said'"I saw the tree,the branch of the tree,the leaves,the sky, the bird and it's eye.The sage asked this discipleto wait.
Finally he called Arjuna what he was saw.Arjuna replied that he saw only the eye of the bird.Dronacharya was very happy of Arjuna's answer and he said to Arjuna that very good And then he can shoot.The arrow went stright to the eye of the bird and it hit the eye of the bird.

THE STORY OF PEPER
The origin of paper dates back to the early Egyptian Civilisations. TheEgyptian used the stalks of the Papyrus plant to the maufacture a material resembling paper.
Over the centuaries several changes have been made and many new materials used in paper making process, but the basic of most paper is still fiber of plant.

COMMUNICATION{bow-bow theory}
We all know that when a dog bark it goes'bow-bow. But how does that explain the orgi of langauge?
According to the bow-bow theory, langauge began as initation of the sound made by the animals andoter natural sounds. Thus the word 'moo'describes the noise of cow, while 'meow' sound just like a kitten cry and 'plop'sound just like a drop of water falling.
But this is only a theory and many people don't agree with it.

LITTLE BOY AND FAT MAN
Both the Littleboy and the Fatman are two important characters of the dark history of humanity.Littleboy was the nick name given to the uranium bomb dropedin Hirosima during second world war. Fatman was pseudonym bomb thrown in Nagasaky. Littleboy caused the death of 1,00,000 peoples and Fatman daimed 75,000 lives. The famous scientist Albert Einstein was the master brain behind the makig of Atomic Bomb. On 6th august 1945 America put atombomb in Hirosima and on 9th in Nagasaki.August 6th is commemorated as Hirosima day.
MAGNATIC FORCE
Attraction or repulsion that arises between electrically charged particles that are in motion. While only electric force exist among stationary electric charges, with both electric and magnetic force exist among moving electric charges.The magnetic force between two moving is the force exerted on one charge by a magnetic field created by other.This force is zero if the second charge is travelling in the direction of the magnetic field due to the first and is greatest i it travels at right angle to the magnetic field. Magnetic force is responsible for the action of electric motor and the attraction between magnet and iron.
