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.
