Hi, Having watched a Google presentation by (the fabulous) Matt Cutts earlier today, I was thinking about how the brain works like the Google search engine does. It made sense that both tools have to wade through large amounts of information in order to get what the user is needing. A brain needs to take a whole load of information that is being received and store it logically so that it's easier to find and also needs to assess the value of the information. It does this by making the connections between other peices of information that it knows, as well as things that other senses are picking up. If a thought is repeatedly exercised, then a stronger link is made to that thought, and it becomes more vivid in the mind. Any person familiar with Google will see the similarity with its' basis for search engines. It sorts the ranking out by analyzing the importance of the page, how relevant it is to what it wants, and how much that thought is accessed - by use of keywords and backlinks. Teachers make attempts to create links between objects, colours and sounds to new learning subjects to stimulate a response in the brain, in the same way that SEO's try to associate their content with more important and established content on the web, and Google has to process that and take into account any fraudulent or suspicious links. Apologies if this has been picked up on before, but I just noticed it all and it's really fascinating to see how goodness knows how many years of evolution of the brain has been harnessed and put into practice by Google to make the www a better place .
