43.History of robot.

                     A robot is a mechanical or virtual agent, usually an electro - mechanical machine that is guided by a computer program or electronic circuitry.  Robots can be autonomous or semi-autonomous and range from humanoids such as Honda's Advanced Step in Innovative Mobility (ASIMO) and Tosy's TOSY Ping Pong Playing Robot (TOPIO) to industrial robots, collectively programmed 'swarm' robots, and even microscopic nano robots.  By mimicking a life like appearance or automatic movements, a robot may convey a sense of intelligence or thought of its own.

                Robotics is the branch of technology that deals with the design, construction, operation, and applications of robots, as well as computer systems for their control, sensory feedback, and information processing.  These technologies deal with automated machines that can take the place of human in dangerous environment or manufacturing processes, or resemble humans in appearance, behavior, and / or cognition.  Many of today's robots are inspired by nature contributing to the fields of bio-inspired robotics.  

42.Chairs

                         This is about chairs.  Please read it.

                                        "Chairs are useful,
                                          not even anything is harmful.
                                          We can sit on them with ease,
                                          we can move them to get us some breeze.
                                          Chairs are made up of wood,
                                           they're also very good.
                                           It would be nice if it is painted in blue,
                                           if the chair's one leg is broken, stick it with glue." 

41.Christopher's friendship.

                                 There lived a boy called Albert.  He was studying in 10th standard.  His friend was a boy named Christopher.  He was always friendly with Albert whereas Albert always hated Christopher.  When Christopher took leave, to copy the homework, he came to Albert's house.  But poor Christopher, for his bad luck, Albert drove him away from his house.  When Christopher called Albert in the mobile to listen to the home work, that time also Albert cut the mobile.  The next day on school, when Christopher talked to Albert, at least he would talk to him.  That time he did not talk at all.  Christopher asked why many times, but, Albert kept quiet and did not answer at all.  After the school was over, Christopher ran after Albert asking why? why? why?  At last Christopher became very tired of asking and went home.  He said to his mother that Albert would not talk to him.  His mother said,"If he's not talking to you, you also don't talk to him.  Why do you need to beg at that boy?"  On the next day, Christopher did not talk to Albert at all.  That went on till 2 days.  At the third day Albert asked Christopher,"Why didn't you talk to me for 2 days, Christopher?"  Christopher replied,"You did not talk to me, so I did not talk to you."  So, Albert realized and said,"I was checking if you were trying to be my friend."  From that day, they both became close friends that no one in the world could be. 

40.History of computer.

                     Without getting too technical, the first 'computing machine' was created by Charles Babbage in 1822.  His idea was not really to create a computer as we know them today, but instead, to create a machine that would compute math problems.  He was tired of human errors in completing math problems, so he sought to create an infallible math machine, but what he got instead was a machine that was the basis for what we know now as the computer.

39.The butterfly.

            This is a poem of a butterfly.  Please read it.

                                                 "Butterflies are beautiful things,
                                                  it has a pair of wings.
                                                  I have a butterfly,
                                                  it flies a little high.
                                                  It sucks nectar,
                                                  its name is Suckter.                  
                                                  They fly every where,
                                                  we can find it any where."

37.History of televsion.

                        The history of television comprises the work of numerous engineers and inventors in several countries over many decades.  The earliest proposal was in 1908, in a paper by A.A.Campbell Swinton and postulated the use of cathode rays.

                        The first practical demonstrations of television, however were developed using electromechanical methods to scan, transmit, and reproduce an image.
