pplications Intelligent machines can do more than  play chess or make cars. One really useful  application is to make use of their excellent memories. Everything we know   about a subject can   be programmed into   a machine, which can  then be used as an  electronic expert. This  has already been tried  for medical conditions.  The machine processes   all the facts about the patient’s problem, figures  out what it is, and comes up with the right treatment.

        Artificial intelligence When we learn, nerve cells in our brains are  rewired into new networks. Engineers have  found ways of making computer circuits automatically do the  same thing in response to  good or bad results. This  means they can “learn”  anddisplay what is known   is  what and display as artificial intelligence.
