Sargasso Sea

When Columbus sailed the Sargaso Sea     
His sailors did shudder and cry:
"Our ship will sink in this horrible sea.
We'll never get home-we'll die !"

Some people say it's a dark,dangerous trap for sailing ship.But it isn't.Some say it's a giant floating island.But it's not.Others call it an ocean jungle.Wrong.It's the Sargaso Sea - a place in the North Atlantic Ocean where the water is so clam that seaweed grows there.The top of the still water is so crowded with tangled seaweed that captains once feared their ships would get caught in it and be pulled down.

The Man Who Belived That Children Should Have Fun


Even though Charles Dickens lived more than 100 years ago,he was your friend.He wrote stories about boys and girls and grown ups who lived in England.Partly because of those stories,children are treated better now than they were when Dickens lived.

If she had been a real person you'd have liked Little Dorrit,who had to live in a prison house because her parents were too poor to pay the money they owed.When Dickens was young,his father and mother lived in such a place.
Charles Dickens was not much older than you when he had to quit school and take a job away from home.He worked from morning until night,with very little food to eat and only an attic in which to sleep.He tells about this in his book David Copperfield.In another story Dickens tells us how children were treated in some of the schools of that time.At his own school sometimes he was beaten with the teacher's cane for laughing too loudly or for forgetting his lesson.

Yummy Sardines !


Sardines, or pilchards, are several types of small, oily fish related to herrings, family Clupeidae. Sardines are named after the Mediterranean island of Sardinia, around which they were once abundant.The terms sardine and pilchard are not precise, and what is meant depends on the region. The United Kingdom's Sea Fish Industry Authority, for example, classifies sardines as young pilchards.One criterion suggests fish shorter in length than 6 inches (15 cm) are sardines, and larger ones pilchards.The FAO/WHO Codex standard for canned sardines cites 21 species that may be classed as sardines;FishBase, a comprehensive database of information about fish, calls at least six species "pilchard", over a dozen just "sardine", and many more with the two basic names qualified by various adjectives.

The Earth Fact

You can't measure the speed of an object by itself, it has to be measured relative to something else (this was one of Einstein's realizations).

If we ask the question, "How fast the Earth is moving?" we have to specify that we want the speed with respect to another object. Motion cannot be measured without a reference point. We can ask how fast the earth is moving with respect to its own axis, the Sun, the Milky Way Galaxy, or our Local Group of galaxies.

   •How fast is the Earth spinning?0.5 km/sec
   •How fast is the Earth revolving around the Sun?30 km/sec
   •How fast is the Solar System moving around the Milky Way Galaxy?250 km/sec
   •How fast is our Milky Way Galaxy moving in the Local Group of galaxies?300 km/sec

The Earth spins around its axis as it orbits the Sun. Our entire Solar System slowly orbits around the Milky Way Galaxy. The Milky Way Galaxy belongs to the Local Group of galaxies, where it is also moving.

The Leaders


From the day he was old enough to understand,Prince Charles has known he will be a king of England if he lives longer than his mother,Queen Elizabeth.
The people didn't elect him.They didn't choose him because they thought he was smarter or because he bullied them.They really didn't choose him at all.

In countries where a king or a queen rules,the oldest son-or daughter if there are no son-knows he will someday sit on the throne.Even though Prince Charles become king,he won't have as much power as king used to have.The real leader in England is called the Prime Minister.
Most countries don't have king and queen anymore.And not all countries elect their leaders.The leaders of some countries are called dictators.A dictators is very often a bully-a man who wants to be a leader so much that he'll do almost anything-no matter how cruel to get the job.

Fast Fast Fast with Speed

 
Take the cow. It can be hard to understand the deification of the cow in Indian villages. But pause. In westernized Delhi or Bombay, amid the fizzing pandemonium of the fast lane, watch the awesome cow in awesome slowness chew. Then you know.
Speed is something of a holy cow to modern westernized cultures. On the international foreign exchange markets, up to £200 million can be turned over in little more than a minute. News media can communicate events all but instantaneously. Computers can perform 307 gigaflops per second. Transport policies sacrifice any number of Sites of Special Interest to it, and Brands Hatch is a temple to it.

The attraction of speed is only partly the exhilaration of acceleration; much to do with competition, with overtaking. The thrill is not in going fast, but in going faster then the rest. Mark Marchant, professional racing driver at Brands Hatch, says: "Overtaking, you begin to feel invincible."
