True Wealth

Short Stories - True WealthOne day a father of a very wealthy family took his son on a trip to the country with the purpose of showing his son how the poor people live so he could be thankful for his wealth.
They spent a couple of days and nights on the farm of what would be considered a very poor family.
On their return from their trip, the father asked his son, “How was the trip?” “It was great, Dad.” “Did you see how poor people can be?” the father asked. “Oh yeah” said the son. “So what did you learn from the trip?” asked the father.
The son answered, “I saw that we have one dog and they had four. We have a pool that reaches to the middle of our garden and they have a creek that has no end.” “We have imported lanterns in our garden and they have the stars at night.” “Our patio reaches to the
front yard and they have the whole horizon.” “We have a small piece of land to live on and they have fields that go beyond our sight.” “We have servants who serve us, but they serve others.” “We buy our food, but they grow theirs.” “We have walls around our property to protect us; they have friends to protect them.”
With this the boy’s father was speechless. Then his son added, “Thanks dad for showing me how poor we are.

Why Do Turtles and Tortoises Live So Long?

Compiled by Pitara team


Some of them are huge, like the giant tortoises of the Galapagos Islands - they weigh beyond 200 kg; their shells are more than a metre long. The beauty is that they hatch from eggs that are no bigger than a hen's!
Why do Turtles and Tortoises Live So Long?, 5W&H for kids: 5_1.gif They manage to live so long because the important parts of their bodies do not become weak with age, as in the case of humans and birds. In fact, they continue to grow very, very slowly for as long as they live. Their body does not need much energy to survive. They can live for long periods without water or food.
Turtles and tortoises face other risks to their life. After birth, their shells take some months to become hard. Till then, they are an easy prey for birds and fish. The other risk to their life comes from pollution of their living environment.

Amelia Earhart

By Brishti Bandyopadhyay; Illustration by Shinod AP

Amelia Earhart was one of the world's most celebrated aviators. She broke records and charted new skies in the course of her short life. She disappeared while she was on a flight around the world.

Earhart was born on July 24, 1897, in Atchison, Kansas. She was the elder of Edwin Stanton and Amy Otis Earhart's two daughters. Childhood was not happy for the two bright sisters. Their father was an alcoholic and lost jobs often. The family travelled a great deal.

Amelia Earhart - A brief biography, Biographies for kids: 47_1.gif The girls often recited poetry while doing their chores but also loved sports, including basketball and tennis. Their parents encouraged them to try new things.

Amelia wanted to attend college after finishing school. But, she met some World War I (1914 - 1918) veterans and decided to study nursing, instead.

During the war Amelia worked as a military nurse in Canada and later she became a social worker and taught English to immigrant children.

Besides work, Amelia had one hobby. She enjoyed watching airplane stunt shows, which were popular in the 1920s. Then one day she took a 10-minute plane ride and knew what her vocation would be - she would learn to fly.

Amelia did several odd jobs and with the help of her mother, she put together the fee - $1,000. In those days, $1000 was an extremely large amount of money.

After 10 hours of instruction and several crashes, Amelia was ready to fly. She made her first solo flight in 1921. The flight went well. By the next year, Amelia had saved enough money to buy her own plane.

Till 1928, flying was only her hobby. This changed when Amelia received a call from Captain Hilton H Railey. He asked her to join pilots Wilmer Stultz and Louis Gordon on a flight from the United States to England.

Though Amelia was just a passanger, she became the first woman to cross the Atlantic. The plane they flew in was 'The Friendship' and the trip was made on June 17-18, 1928. A publisher named George Putnam wrote an article on the flight and in 1931, Amelia married him.

After this, Amelia got tremendous publicity. In May 1932, she crossed the Atlantic alone and set a new transatlantic crossing record of 13 hours, 30 minutes. She received a medal from American President Herbert Hoover for this.

Several years later, she became the first woman to fly from California to Hawaii, which was a difficult route.

Amelia's last flight began in June 1937. She and navigator Fred Noonan set out to fly around the world. They were in a twin-engine Lockheed Electra. The two of them took off from Miami in America to South America. Then they crossed the South Atlantic Ocean to Dakar in Africa. From there to Thailand to Australia.

However, after they left Lae in New Guinea for Howland Island, the American coast guard lost contact with the plane. They received a final message on July 2, 1937 at 8:45 am, and Amelia's tone was described as frantic.

Despite an extensive search, the American Navy never found a trace of either the plane or the aviators. Their disappearance is still a mystery.

While some believe that she and Noonan were captured and executed by the Japanese, others feel that President Roosevelt sent Earhart on a secret spy mission. However, none of these theories has been confirmed.

In a tribute to Amelia, her husband published her biography entitled Soaring Wings in 1939. The biography described her adventurous life. What egged Amelia to keep flying? Maybe it was "a lonely impulse of delight."

Sand and Stone

Short Stories - Sand and StoneJohn and James were best friends. They fight for many reasons and but never gave up their friendship. They went in search of a job and visited many places to earn more money. They passed through various places, villages, towns, forests, beaches, and were supporting each other all the way through out their journey.
One day they reached a desert and they had a very little food and water. John told James to eat half the quantity of food and then once they get very tired and feel like they cannot make a step they can eat another half and save water for the late.
However, James disagreed. He wanted to drink water as he was very thirsty. They quarrelled among each other to have water. John slapped James and they walked in silent. They decided to have food and continue their journey. James wrote in sand, ‘My best friend slapped me!’
They shared the meagre amount of food and water and finally reached an oasis. They were very tired after passing through the dry and hot desert. James was so happy to see the oasis and had a lot of fun in the water. While they both were bathing, James was a bit careless and began to drown. John rushed to him and saved James.
James hugged his friend and thanked him. They had a little nap and decided to leave the place. They were about to leave and James carved something on the rock.
It was ‘My best friend saved my life!’
John asked ‘why you were marking all these here James?’ James replied, ‘You slapped me, I wrote in sand. It was definitely not good. However, if you go and see the sand you can find no letter wrote on the sand. Now I carved the good thing on the stone, and it will remain forever!’
We have to forget the bad things done to us and engrave the good things in the stone.

Bruce Lee

Illustrations by: Amarjeet Malik

The Chinese American actor Bruce Lee, was born in San Francisco on November 27, 1940. Born a sickly child, he was named Li Jun Fan a female name by his mother to ward off evil spirits. His dad an Hong Kong opera singer returned back to Hong Kong along with his family in 1941.
As a kid martial arts and bodybuilding were his only preoccupation, studies didn’t interest him. In 1946 he appeared in first of many films as a child actor. He appeared in 20 movies and rarely in school. He soon became involved with a gang and his mother shipped him back to America before his 18th birthday so he could claim his dual-citizenship and avoid winding up in jail.
Bruce Lee - A brief biography, Biographies for kids: 5_1.gif He soon picked up a job teaching the Wing Chun style of martial arts that he had learned in Hong Kong. Lee also studied philosophy at the University of Washington, at the same time acquiring his considerable skills in the martial arts like karate, kung-fu, and so on. Shortly after, Lee landed his first US show-biz role -- Kato in The Green Hornet, A 1966-67 TV superhero drama from the creators of Batman. However, Lee could not get Hollywood to embrace him and hence returned to Hong Kong to make films.
He made the Fists of Fury (1971), his martial arts debut. Almost immediately, he became a cult figure, and the world-wide martial arts phenomenon was under way. The plots of all films he made were uniform: Lee makes a vow not to fight; people close to Lee are exploited and Lee kills in retaliation. The films set box-office records in Asia and Hollywood finally gave him an action movie. But Lee died a month before the release of his first US film Enter the Dragon, considered the king of Kung–Fu movies. During the filming of Game of Death Lee died mysteriously of brain edema.

Why Do Horses Need Shoes?



Clip-clop, clip-clop goes a horse on the road. If you look carefully you will see that it walks on the tips of its toes - like a ballet dancer. Walking on tiptoe for a long time is difficult for us, but horses find it the easiest thing to do.
The foot of a horse is divided into a toe with a broad tip. While other animals have nails and claws, the horse has a hoof surrounding the toe. The hoof area cannot feel any sensation; it is made of dead tissue (A similar example is our fingernails: we do not feel any pain while cutting them, because they are made of dead tissue.) The heels of the horse do not touch the ground.
Why do Horses Need Shoes?, 5W&H for kids: 6_1.gif The centre of the horse's foot is soft. It is called the frog. When the horse is carrying a rider or a heavy load, the hoof comes down heavily on the ground. The frog may not be able to bear the weight and could swell up. The horse could even become lame. It is to prevent this from happening that an iron horseshoe is fixed to the horse's foot. It protects the frog and ensures that the horse can run as fast as the wind, or dance like a ballerina without worrying about its foot. Of course, horses that run free have no need to put on their iron shoes.

Ayatollah Ruhollah Khomeini

Illustrations by: Amarjeet Malik

The Ayatollah (Arabic, "Reflection of Allah") Ruhollah Khomeini became leader of Iran in 1979 by forcing the overthrow of the shah and Prime Minister Shahpur Bakhtiar. Born in Khomein, Iran on May 27, 1900, the son of an ayatollah of the Shiite sect, he studied theology and by 1962 was one of the six grand ayatollahs of Iran's Shiite Muslims. Exiled in 1964 for his part in religious demonstrations against the shah, he was expelled from Iraq in 1978 and moved to France, where he emerged as the leader of the anti-shah movement. In January 1979, after the shah left Iran, he returned to lead the country, becoming faqih (supreme religious guide) for life of Iran's Islamic republic in December.
, Biographies for kids: 34_1.gif In his efforts to transform Iran into an Islamic state, Khomeini was hostile to the West. In November 1979 he supported militant students who invaded the U.S. embassy and precipitated the Iranian hostage crisis. Khomeini and other fundamentalist clerics faced opposition from Western-educated moderates, from minorities within the country, and from various leftist guerrilla groups but gradually consolidated control, imposing rigid censorship, executing members of the opposition, and banning Western customs. Khomeini used the Iran-Iraq war initiated by Iraq in 1980 to help unify the country, although he was less than successful in exporting his revolution and reluctantly accepted a cease-fire in the costly conflict in 1988. After his death, on July 3, 1989, Iran remained a theocracy, although the powers of the president were increased.

Strong Or Weak

There was a proud teak tree in the forest. He was tall and strong. There was a small herb next to the tree.
The teak tree said, “I am very handsome and strong. No one can defeat me”. Hearing this the herb replied, “Dear friend, too much pride is harmful. Even the strong will fall one day”.
The teak ignored the herb’s words. He continued to praise himself.
A strong wind blew. The teak stood firmly. Even when it rained, the teak stood strong by spreading its leaves.
At the same time, the herb bowed low. The teak made fun of the herb.
One day there was a storm in the forest. The herb bowed low. As usual the teak did not want to bow.
The storm kept growing stronger. The teak could no longer bear it. He felt his strength giving way.
Short Stories - Strong or Weak
He fell down. This was the end of the proud tree. When everything was calm the herb stood straight. He looked around. He saw the proud teak had fallen.

What does SOS mean?

 By B Sumangal; Illustration by Sudheer Nath

Recently, sailors on the nuclear submarine that sank in the Baltic Sea were isolated from rescue workers as their radio set got damaged. Luckily their radio operators knew the Morse code and were able to communicate by knocking on the sides of the ship.
There are many explanations for what the words stand for: Save Our Souls; Save Our Ship; Send Our Succour… The meaning of all three is the same - it is a plea for help by someone in distress. That's exactly what SOS is.
It is a coded signal for help that continues to be used by ships, planes and stranded people around the world even 162 years after it was invented by the American Samuel Morse, who invented the first successful telegraph instrument in 1837. The Morse code, as it came to be called, is used to send messages through a telegraph line or the wireless.
What does SOS mean?, 5W&H for kids: 15_1.gif SOS is the easiest code to transmit and recognise. The code consists of three dots, three dashes and three dots . . . - - - . . . One can tap it on the telegraph or signal with a torch or even with a flag.
Before the invention of the code, long distance communication consisted of lamp signals from hilltops, smoke signals and shouted messages. In 1787, M Lammond, a Frenchman invented the first telegraph line that could send messages over a distance by means of electricity. Morse developed the first successful telegraph instrument in 1837.
Called a transmitter, the telegraph instrument converts a message into electrical signals. In 1838, Morse also developed a code that consisted of dots and dashes representing alphabets and numbers. These codes were easier to send over the telegraphic line. The dots and dashes travel across the wire and are picked up by a receiving set.
The electric signals move a metal point to print these dots and dashes on a paper tape. The code can be used to read these dots and dashes and translate the message.
In 1843, the United States Congress approved the first telegraph line from Baltimore in Maryland to Washington DC. In 1844, Morse sent the first message "What has God wrought" on this line using this code.
Because of its simplicity the Morse Code continues to be used even as mobile wireless telephones are replacing telegraph transmission.

Mahatma Gandhi

Illustrations by: Amarjeet Malik

Thinker, statesman and nationalist leader, Mohandas Karamchand Gandhi not only led his own country to independence but also influenced political activists of many persuasions throughout the world with his methods and philosophy of nonviolent confrontation, or civil disobedience.
Born in Porbandar in Gujarat on October 2, 1869, his actions inspired the great Indian poet Rabindranath Tagore to call him "Mahatma" ("great soul"). For him, the universe was regulated by a Supreme Intelligence or Principle, which he preferred to call satya (Truth) and, as a concession to convention, God.
Since all human beings partook of the divine essence, they were "ultimately one". They were not merely equal but "identical". As such, love was the only proper form of relation between them; it was "the law of our being", of "our species". Positively, love implied care and concern for others and total dedication to the cause of "wiping away every tear from every eye." Negatively it implied ahimsa or ‘non violence’. Gandhi’s entire social and political thought, including his theory of Satyagraha, was an attempt to work out the implications of the principle of love in all areas of life.Gandhi himself felt that he was most influenced by his mother whose life was an "endless chain of fasts and vows" as a devout adherent of Jainism, a religion in which ideas of nonviolence and vegetarianism are paramount.
Mahatma Gandhi - A brief biography, Biographies for kids: 22_1.gif Married by arrangement at 13, Gandhi went to London to study law when he was 18. He was admitted to the bar in 1891 and for a while practiced law in Bombay. From 1893 to 1914 he worked for an Indian firm in South Africa. During these years Gandhi's humiliating experiences of overt racial discrimination propelled him into agitation on behalf of the Indian community of South Africa. He assumed leadership of protest campaigns and gradually developed his techniques and tenets of nonviolent resistance known as Satyagraha (literally, "steadfastness in truth").
Returning to India in January 1915, Gandhi soon became involved in labor organizing. The Jallianwala Bagh massacre of Amritsar (1919), in which troops fired on and killed hundreds of nationalist demonstrators, turned him to direct political protest. Within a year he was the dominant figure in the Indian National Congress, which he launched on a policy of noncooperation with the British in 1920-22. Although total noncooperation was abandoned, Gandhi continued civil disobedience, organizing protest marches against unpopular British measures, such as the salt tax (1930), and boycotts of British goods.
Gandhi was repeatedly imprisoned by the British and resorted to hunger strikes as part of his civil disobedience. His final imprisonment came in 1942-44, after he had demanded total withdrawal of the British (the "Quit India" movement) during World War II.
Gandhi also fought to improve the status of the lowest classes of society, the ‘Untouchables’, whom he called harijans ("children of God"). He believed in manual labor and simple living; he spun thread and wove cloth for his own garments and insisted that his followers do so, too. He disagreed with those who wanted India to industrialize.
Gandhi was also tireless in trying to forge closer bonds between the Hindu majority and the numerous minorities of India, particularly the Muslims. His greatest failure, in fact, was his inability to dissuade Indian Muslims, led by Muhammad Ali Jinnah, from creating a separate state, Pakistan. When India gained independence in 1947, after negotiations in which he was a principal participant, Gandhi opposed the partition of the subcontinent with such intensity that he launched a mass movement against it. Ironically, he was assassinated in Delhi on January 30, 1948, by a Hindu fanatic who mistakenly thought Gandhi's anti-partition sentiment were both pro-Muslim and pro-Pakistan.
Gandhi’s intellectual influence on Indians has been considerable. Some were attracted by his emphasis on political and economic decentralisation, others by his insistence on individual freedom, moral integrity, unity of means and ends, and social service; still others by his satyagraha and political activism. For some students of India, Gandhi’s influence is responsible for its failure to throw up any genuinely radical political movement. For others, it cultivated a spirit of non-violence, encouraged the habits of collective self-help, and helped lay the foundations of a stable, morally committed and democratic government. Gandhi’s ideas have also had a profound influence outside India, where they inspired non-violent activism and movements in favour of small-scale, self-sufficient communities living closer to nature and with greater sensitivity to their environment. Prominent among these are Martin Luther King in the United States and, more recently Nelson Mandela in South Africa.

Why Do Stars Twinkle?

By Upasana Sharma; Illustration by Kusum Chamoli

Watching stars on a moonless night can be an quite an interesting experience. As clusters of stars take familiar forms - of a bear, a man in armor wielding a sword, millions of other stars simply twinkle. As if they were playing hide and seek with one's eyes.
Why do stars twinkle?
We all know that each star is actually like the sun. And the huge collection of stars on the night sky is like a collection of many, many suns. But, the sun does not twinkle, one would point out.
Right.
Why Do Stars Twinkle?, 5W&H for kids: 10_1.gif The sun does not twinkle. It blazes down on us. If any of the stars were close to us, they would have also blazed down on us, or even burnt us down.
The stars look different because they are far away. And the light from the stars travels a very long distance to reach us. Actually very little of the light finally manages to reach us. Besides, it passes through the earth's atmosphere before reaching us. As the light enters the atmosphere, impurities like dust interfere its path. So, sometimes it is visible, and sometimes it is not. This effect is called twinkling.
There are certain stars in the night sky that don't twinkle. Well that's because they are not stars at all. They are planets. Planets do not twinkle because unlike stars they do not have their own light. They are like the moon. They reflect light from the Sun.
So what is a star? A star is born when a cloud of lots of different gases, mainly hydrogen, get together. The gas particles attract each other and slowly get compressed to form a huge mass of gases. And, as this mass grows, the temperature inside grows too. Until such time when it bursts like a bomb. This explosion creates a gas called helium, which is inflammable in nature. The helium becomes its fuel and it continues burning. Thus is a star born.
No wonder the heavier stars burn more furiously. They have bigger explosions, where more helium is released, providing more fuel. At the same time, these bigger and brighter stars have a shorter life. Why? Because they use up their fuel more quickly. The life of a smaller and lighter star can be as much as 100 times longer.

Muhammad Ali

 Illustrations by: Amarjeet Malik

American boxer Cassius Marcellus Clay Jr, was born on January 17, 1942 in Louisville, Kentucky. Better known as Muhammad Ali, he was perhaps the most celebrated sports figure in the world during most of the 1960s and '70s. His rise to prominence may be attributed to a combination of circumstances his role as a spokesman for and idol of blacks; his vivacious personality; his dramatic conversion to the Black Muslim religion; and most important, his staying power as an athlete. Ali first came to world attention in 1960, when he won the Olympic light-heavyweight championship. He then won a controversial championship bout from Sonny Liston in 1964 to gain the heavyweight title. He produced a steady stream of headlines. The fight was questioned because Ali seemed to be quitting before the bout was over. After that he produced a steady stream of headlines. He then changed his name to Muhammad Ali. He was the first boxer to benefit from satellite television, making him all the more visible.
Muhammad Ali - A brief biography, Biographies for kids: 3_1.gif Ali, however, proved to be a "fighting champion," accepting the challenges of every heavyweight with ranking credentials. He was stripped of his title in 1967 for refusing to join the Army during the Vietnam War. The government prosecuted him for draft dodging and the boxing commissions took away his license. He was idle for three and a half years at the peak of his career. In 1971 the Supreme Court ruled that the government had acted improperly and was allowed to resume fighting. He won back the championship in 1974 in about with George Foreman. He lost the crown again in 1978 to Leon Spinks but regained it the same year, thus becoming the first man to win the title three times. Other than Joe Frazier (in 1971) and Spinks, the only boxers to defeat Ali, who had a 55-5 record, were Ken Norton (1973), who later lost to Ali; Larry Holmes (1980), who foiled Ali's try for a fourth heavyweight championship; and Trevor Berbick (1981), after which fight Ali retired. The Ali-Frazier fights rank among the greatest in fistic history. In later years Ali developed Parkinson’s disease, caused by blows to the head from boxing.

Why are Some Reptiles Brightly Coloured?

By B Sumangal; Illsutration by Sudheer Nath

Most animals have skin colour that makes them merge into their surroundings. They become near invisible unless you look very closely. But some reptiles such as the sea-snakes, coral snakes and frogs of Central and South America are brilliantly coloured or have bright bands like deep yellow, orange, pink on their bodies.
They are easily visible among the green leaves or brown earth. This is because these animals are poisonous. The colouring is a warning to other animals, especially their natural enemies, to avoid eating them. The frogs of Central America called the dart-poison frogs secrete a poison from their skin.
Why are Some Reptiles Brightly Coloured?, 5W&H for kids: 16_1.gif The bright colours of the reptiles act as a warning to would-be predators to avoid eating them. The poison from the skin tastes so awful that the bird or snake quickly spits out the frog before the poison can take effect. Birds and other snakes learn to avoid these bright frogs and their poison.
It is interesting that similar bright colour patterns have been developed over the centuries by many non-poisonous animals too as a survival mechanism to fool predators. Since predators avoid attacking these brilliant coloured animals, thinking of them as poisonous, these animals, too, escape getting killed.
Even in the inset world, harmless insects, butterflies and moths mimic their poisonous fellow beings. The imitator is protected not only by the colouring and shape but also by the predator's experience with the poisonous kind - once bitten, twice shy!

The Lion and the Mouse

Short StoriesOnce when a Lion was asleep, a little Mouse began running up and down upon him. This soon wakened the Lion, who placed his huge paw upon him and opened his big jaws to swallow him.
"Pardon, O King!" cried the little Mouse, "Forgive me this time. I shall never repeat it and I shall never forget your kindness. And who knows, but I may be able to do you a good turn one of these days?"
The Lion was so tickled at the idea of the Mouse being able to help him, that he lifted up his paw and let him go.
Short StoriesSometime later a few hunters captured the King and tied him to a tree while they went in search of a wagon to carry him on.
Just then the little Mouse happened to pass by, and seeing the sad plight in which the Lion was, ran up to him and soon gnawed away the ropes that bound the King of the Beasts. "Was I not right?" said the little Mouse, very happy to help the Lion.

Albert Einstein

Illustrations by: Amarjeet Malik

German-American physicist Albert Einstein contributed more than any other scientist to the 20th-century vision of physical reality. In the wake of World War I, Einstein's theories, especially his theory of relativity, seemed to many people to point to a pure quality of human thought, one far removed from the war and its aftermath. Seldom has a scientist received such public attention for having cultivated the fruit of pure learning.
Born in Ulm in Germany on March 14, 1879, Einstein’s parents were nonobservant Jews who moved from Ulm to Munich when Einstein was an infant. The family moved yet again to Milan in Italy in 1894, when the family business of manufacturing electrical apparatus failed.
Albert Einstein - A brief biography, Biographies for kids: 36_1.gif At this time Einstein decided officially to relinquish his German citizenship. Within a year, still without having completed secondary school, Einstein failed an examination that would have allowed him to pursue a course of study leading to a diploma as an electrical engineer at the Swiss Federal Institute of Technology (the Zurich Polytechnic). He spent the next year in nearby Aarau at the cantonal secondary school, where he enjoyed excellent teachers and first-rate facilities in physics. Einstein returned in 1896 to the Zurich Polytechnic, where he graduated (1900) as a secondary school teacher of mathematics and physics.
After a lean two years he obtained a post at the Swiss patent office in Bern. The patent-office work required Einstein's careful attention, but while employed (1902-09) there, he completed an astonishing range of publications in theoretical physics. For the most part these texts were written in his spare time and without the benefit of close contact with either scientific literature or theoretician colleagues. Einstein submitted one of his scientific papers to the University of Zurich to obtain a Ph.D. degree in 1905. In 1908 he sent a second paper to the University of Bern and became a lecturer there. The next year Einstein received a regular appointment as associate professor of physics at the University of Zurich.
By 1909, Einstein was recognized throughout German-speaking Europe as a leading scientific thinker. In quick succession he held professorships at the German University of Prague and at the Zurich Polytechnic. In 1914 he advanced to the most prestigious and best-paying post that a theoretical physicist could hold in central Europe: professor at the Kaiser-Wilhelm Gesellschaft in Berlin. Although Einstein held a cross-appointment at the University of Berlin, from this time on he never again taught regular university courses. Einstein remained on the staff at Berlin until 1933, from which time until his death (in 1955) he held an analogous research position at the Institute for Advanced Study in Princeton, N.J.
Einstein’s special theory of relativity assumed that light travelled through space in the form of photons. He also asserted that the speed of light in a vacuum is invariant, and is independent of the speed of its source. His equations showed that mass increases with velocity, and that time is foreshortened by velocity.
Until the end of his life Einstein sought a unified field theory, whereby the phenomena of gravitation and electromagnetism could be derived from one set of equations. After 1920, however, while retaining relativity as a fundamental concept, theoretical physicists focused more attention on the theory of quantum mechanics - as elaborated by Max Planck, Niels Bohr, Werner Heisenberg, and others - and Einstein's later thoughts went somewhat neglected for decades. This picture has changed in more recent years. Physicists are now striving to combine Einstein's relativity theory with quantum theory in a "theory of everything," by means of such highly advanced mathematical models as superstring theories.

COMPOUND NOUNS

Formation

Words can be combined to form compound nouns. These are very common, and new combinations are invented almost daily. They normally have two parts. The second part identifies the object or person in question (man, friend, tank, table, room). The first part tells us what kind of object or person it is, or what its purpose is (police, boy, water, dining, bed):
What type / what purpose What or who
police man
boy friend
water tank
dining table
bed room
The two parts may be written in a number of ways :
1. as one word.
Examples policeman, boyfriend
2. as two words joined with a hyphen.
Examples dining-table
3. as two separate words.
Examples fish tank.
There are no clear rules about this - so write the common compounds that you know well as one word, and the others as two words.
The two parts may be: Examples
noun + noun bedroom
water tank
motorcycle
printer cartridge
noun + verb rainfall
haircut
train-spotting
noun + adverb hanger-on
passer-by
verb + noun washing machine
driving licence
swimming pool
verb + adverb* lookout
take-off
drawback
adjective + noun greenhouse
software
redhead
adjective + verb dry-cleaning
public speaking
adverb + noun onlooker
bystander
adverb + verb* output
overthrow
upturn
input

Compound nouns often have a meaning that is different from the two separate words.
Stress is important in pronunciation, as it distinguishes between a compound noun (e.g. greenhouse) and an adjective with a noun (e.g. green house).
In compound nouns, the stress usually falls on the first syllable:
a 'greenhouse = place where we grow plants (compound noun)
a green 'house = house painted green (adjective and noun)
a 'bluebird = type of bird (compound noun)
a blue 'bird = any bird with blue feathers (adjective and noun)
*Many common compound nouns are formed from phrasal verbs (verb + adverb or adverb + verb).

Examples

breakdown, outbreak, outcome, cutback, drive-in, drop-out, feedback, flyover, hold-up, hangover, outlay, outlet, inlet, makeup, output, set-back, stand-in, takeaway, walkover.

Why are Eggs Oval?

By B Sumangal; Illustration by Sudheer Nath

Have you ever climbed a tree and peeked into the nest of a crow or a sparrow? Or looked into that flowerpot where the noisy pigeon decided to lay its eggs? The sight of a mother hen sitting on a bunch of fresh white eggs is great, though most of us see them only when they land on the breakfast table every now and then.
Eggs come in different colours. They may be blue, blue-green, yellow, spotted, blotched or white. No egg looks identical. Even those eggs that are laid in a clutch or at one time may have different colours. Most eggs are oval, and sometimes they are long and elongated. One end is slightly larger and heavier while the other end is smaller and conical.
Why are Eggs Oval?, 5W&H for kids: 12_1.gif The shape of the egg has an important use. It protects the chick inside, until it is time for it to break out of its shell. For, even if you press from the outside, the shell will not break unless the chick inside presses too. The chick does it by tapping from inside with its soft beak when it is ready to face the world.
How does the chick come out? Baby birds in fact have an 'egg tooth'. This is a tiny knob at the tip of the beak to help them break out of the shell. It takes a chick 30 minutes to an hour to break the shell. Some albatross chicks have been known to take five to six days to break out as the shell is so thick!
Most nests are shaped like a large bowl - the right shape for oval eggs to rest without rolling out and falling down. Birds that don't build elaborate nests, like the penguin, the tern and other sea birds, have elongated eggs.
Since these birds lay eggs on rocky ledges or on cliffs, the elongated shapes prevent the eggs from rolling over and breaking on the rocks. Instead they just spin around.
Eggs must be kept warm in order to hatch - about 35 degree centigrade (That is about as warm as an early summer day in northern India). The adult bird provides constant warmth by sitting on the eggs or incubating them. Not only that, the bird keeps turning the eggs around so that all parts of the egg receive the same amount of warmth.
Among most kinds of birds it is the female that incubates the eggs, but in some species it is the adult male which does the hatching. The only bird that doesn't hatch its own chicks is the cuckoo.
The bird is so cunning that it lays its eggs in other smaller bird's nest. Since the eggs look similar the mother bird doesn't realise that it is not hers and sits and hatches the cuckoo's eggs too!
The ostrich lays the largest and heaviest eggs. Each egg weighs around 1.7 kg (3.7 lb) and will not break even if a man weighing 120 kg stands on it. That is how hard the egg is. In fact the eggs are so large that the people living in the Kalahari desert in West Africa use them as a water-bottle!
