What is Intelligence?

The age-old question regarding intelligence still remains unanswered...Why are some people more intelligent than others?

Some children are exceptionally gifted from an early age, they learn more quickly and efficiently than most adults and soon amaze all who know them in the areas of science, literature, music, painting and sports.

Psychologists use the term ‘precocious’ to define such children. While they are in every way normal there are specific features of the brain that are more developed. Hence it is not the anatomy but their ability to possess information that makes them gifted.

However, since not enough is known about the complex network of the brain, scientists do not know enough to identify these individual abilities in the micro structures of the brain.

Another difficulty is the lack of general definition of intelligence. We know it as a general term to combine a number of brain functions. We know that everybody has intelligence, even animals.

There are also many aspects related to it such as ability to understand, ability to convert information into action, the capacity for abstraction, recalling information and the most important - common sense. It is therefore difficult to evolve a definition that the would completely define the term INTELLIGENCE.

"FACTS" we know that are not so...

Almost everybody knows that Wellington’s final battle against Napoleon was fought at Waterloo. And that bulls see red. But, like a lot of other things we know, these “facts” just aren’t so. The battle of Waterloo was really fought four kilometers away from Waterloo, between the villages of Plancenoit and Mont St Jean. And investigations have established that bulls are actually “colour-blind” – they cannot distinguish one colour from another. This article is an attempt to set the record straight on some more such misinformation.

Moth-eaten:

Moths, contrary to the popular notion, do not eat clothes. Some, as a matter of fact, don’t eat anything at all during their adult lives, which are (not surprisingly) brief. It’s the larvae that do the damage; by the time moths are flying out of the cupboard, it’s too late.

Sherlock Holmes:

At no point in any of the 56 short stories and four novels that Arthur Conan Doyle wrote about his famous detective does Holmes say, “Elementary, my dear Watson.”

S.O.S.:

The universal symbol requesting aid, contrary to what is often said, doesn’t stand for “Save Our Ship,” or “Save Our Souls.” It doesn’t, in fact, stand for anything. It was selected because it is very simple, both to remember and to transmit in Morse code – three dots, three dashes, three dots.

The bagpipe:

While the bagpipe is considered to be the national instrument of Scotland, historically it is hardly more Scottish than Irish. It is a very ancient instrument – as old as ancient Persia – which was introduced into the British Isles by the Romans. Surprisingly enough, some form of the bagpipe is found in Spain, Italy, France, the Balkans, and even Czechoslovakia.

Frankenstein:

A common misconception is that the name of the monster in Mary Shelly’s book: Frankenstein, or the Modern Prometheus, is Frankenstein. Frankenstein was not the name of the monster but the name of the person who created the monster.

Steam:

You just think you can see it. Like most other gases, steam is invisible. Only when it cools enough so that minute droplets of water condense, is it visible. If one looks closely at the spout of a boiling kettle, one can observe a small space of what looks like air between the spout and the mist. That is steam.
