" or "who is the richest person in theworld? " unfortunately, the computer can only decide three things, namely: isone number less than another? are two numbers equal? and, is one numbergreater than another? a computer can solve a series of problems and make thousands of logicaldecisions without becoming tired. it can find the solution to a problem in afraction of the time it takes a human being to do the job. a computer can replace people in dull, routine tasks, but it works according tothe instructions given to it. there are times when a computer seems tooperate like a mechanical 'brain', but its achievements are limited by theminds of human beings. a computer cannot do anything unless a person tellsit what to do and gives it the necessary information; but because electricpulses can move at the speed of light, a computer can carry out greatnumbers of arithmetic-logical operations almost instantaneously. a personcan do the same, but in many cases that person would be dead long beforethe job was finished.

The drama of shakespeare "romeo and juliet" i read only this year. the film, based on its motives, looked much earlier. and the fact that "there is no sadder story in the world than the tale of romeo and juliet", i knew from the very childhood. and i am sure that many people, not yet opening the volume of shakespeare, already knew about the heroes of this drama, because all lovers, happy or unhappy, are the same romeo and juliet, capable of faithful and passionate love, and all love, as you know, its tragic. romeo montague and juliet capulet are children from warring families, who are at war so that even the servants of the warring parties do not tolerate each other. romeo is in love with a certain rosaline. but, having penetrated with friends at the ball into the house of enemies of his family, he meets juliet. rosalina is forgotten romeo understands "that caught in the network." juliet also at first sight fell in love with the young montague. later in the garden of the capulet romeo and juliet swear allegiance to each other. soon they secretly get married. on the same day, romeo kills tybalt, the nephew of lady capulet, in a duel. he is being punished. "romeo is banished," repeats and repeats juliet, unable to believe that she will never see her lover again. meanwhile, juliet wins the young earl of paris, and her parents consent to this marriage. the unfortunate girl rushes for help to her brother lorenzo, who crowned the lovers, and he comes up with such a plan: juliette drinks a special drink and falls asleep with a strange dream similar to death, and himself the monk summons romeo. the plan was a success. relatives and relatives cry over the "dead" juliet and take her to the family crypt of capulets. meanwhile the messenger from his brother lorenzo did not manage to deliver romeo a letter. the unhappy young man believed that his fiancee had died. he buys poison and goes to the cemetery where he kills paris, who happened to be there accidentally. then he enters the tomb, lies next to juliet and drinks poison. his death was instantaneous. waking up and seeing beside him dead romeo, the girl stabs herself with a dagger.
