There are so many things lying scattered around us that we use everyday without giving a second thought about their origins. We are so used to them that we feel they have always been around. But is this true? Have you ever wondered, where have these things come from? Each and every thing in this world has a tale of its own regarding its origin. Consider the pen in your hand, or the television that entertains you. These things did not exist barely a few decades or a few centuries ago. The eraser, pencil, shoes, chairs, tables and so many other things in our lives are the successful outcome of research being conducted over the centuries. The hard work and dedication of these inventors and discoverers has gone into making these things. Scientists and inventors worked day and night, even labouring under unfavourable conditions, to bring these things into our lives.
