In years ten, eleven and twelve I study an artist by the name of Salvador Dali; particuarly his painting 'The Persistence of Memory'. When researching this artist and his work in books and reliable internet sources I learnt a great deal into the depth of this mad man and his strange work.

When looking in Wikipedia however, the write up on 'The Persistence of Memory' was false and i knew this for a fact. It states:
The original idea of this painting came from a memory of Dalí's from childhood. While undergoing a routine physical, the Doctor asked Dalí to stick out his tongue. This phrase in Spanish sounded much like the words for "melting clocks." http://en.wikipedia.org/wiki/Persistence_of_Memory

Infact, Dali had an infatuation with the idea of soft and hard. The original idea of this painting came to Dalí on a hot summer's day. He was at home with a headache while Gala was out shopping. After his meal he noticed some half eaten Camembert cheese and how runny it had become on account of the heat of the sunny day. That night, while he had been searching his soul for something to paint, he had a dream of clocks melting on a landscape. He went back to the unfinished he had been working on, which had a plain landscape with rocky cliffs in the background and a tree on a platform. Over two or three hours he added in the melting pocket watches which made this the iconic image it is today.

It is easy to see that this article is incorrect because there are no resources listed so you don't know where the information is coming from.

Wikipedia is a useful site in the sense that if you are unsure as to what something is, searching it on wikipedia will give you some idea. However, it's important to keep in mind that not all the information will be correct as anyone can go into the site and change the information.

The article on Anothony Kiedis in Wikipedia however, has a large list of sources and having read his autobiography I can see nothing wrong with this article. http://en.wikipedia.org/wiki/Anthony_Kiedis

When researching on wikipedia it's important to look for the sources to find out if someone has put solid research into the article or whether they are talking rubbish.
