...property of attracting light objects like bits of paper. In the 17th century, William Gilbert discovered that, glass, ebonite etc, also exhibit this property, when rubbed with suitable materials. The substances which acquire charges on rubbing are said to be ‘electrified’ or charged. These terms are derived from the Greek word elektron, meaning amber. The electricity produced by friction is called frictional electricity. If the charges in a body do not move, then, the frictional electricity is also known as Static Electricity. 1.1.1 Two kinds of charges (i) If a glass rod is rubbed with a silk cloth, it acquires positive charge while the silk cloth acquires an equal amount of negative charge. (ii) If an ebonite rod is rubbed with fur, it becomes negatively charged, while the fur acquires equal amount of positive charge. This classification of positive and negative charges were termed by American scientist, Benjamin Franklin. Thus, charging a rod by rubbing does not create electricity, but simply transfers or redistributes the charges in a material. 1 1.1.2 Like charges repel and unlike charges attract each other – experimental verification. A charged glass rod is suspended by a silk thread, such that it swings horizontally. Now another charged glass rod is brought near the end of the suspended glass rod. It is found that the ends of the two rods repel each other (Fig 1.1). However, if a charged ebonite rod is brought near the end of the suspended rod,...

Therefore this essay is an addition to many essay available on this site for aim of life. Give your comments below.
Wright brothers invented the Aeroplane and since then everyone has dreamed of flying. To fly high like the bird and reach the horizon. I first saw an Aeroplane flying when I was a young lad and then immediately I asked my mother everything about it.
My mother showed me the book of aviation history and I grew fascinated with it. Stories about Amelia Earhart inspired me and then I took the biggest decision of my life i.e. to become a pilot. I would speak to myself about how amazing it would be to fly that iron bird in the sky, to fly and reach the sky and to travel the world.
I wanted to become a pilot because it made me feel adventurous. Spending all my childhood listening to all the fascinating and fiction stories about owning a plane and traveling around the world, meeting new people, seeing different traditions and culture etc.
As I grew older, this aim also grew with me, it made me feel responsible and more determined towards my dream. I started reading more and more about the aviation history and how famous people made it big and became the most successful pilots. A new spark grew in me and among the various types of flight career, I wanted to become an Airshow stunt pilot because it was challenging. Making a show out of aerial acrobatics was something out of an ordinary thing.
But I was always skeptic about my dreams, I felt that this dream was larger than my life and my capability to do it was not enough but my ultimate inspiration was that bird who would fly above my head every day, mocking me to compete with him and so I did. My parents were my precious treasure of motivation because they made my feel that each and everyone has the capability to do anything and this particular optimistic perspective made me believe in myself and my dreams. If I have the capability to dream it, then definitely I will have the courage to pursue it.
So here I am, after 30 years. I can feel my dream (Of becoming a pilot) fresh even now because I am living my dream, it was not easy to pursue it, but somehow I made my aim my life and my ultimate goal. Believe in yourself, no matter what.
