Elementary Mechanics-Introduction ELEMENTARY MECHANICS In our everyday life, we come across a wide variety of objects in motion. The branch of physics dealing with the motion of bodies and bodies at rest in equilibrium is called mechanics. We use the Read more

## Discovery and development of atomic age

Discovery and development  1896 – Henri Becquerel notices that uranium gives off an unknown radiation which fogs photographic film. 1898 – Marie Curie discovers thorium gives off a similar radiation. She calls it radioactivity. 1903 – Ernest Rutherford begins to speak of the possibility of atomic energy. 1905 – Albert Einstein formulates the special theory of Read more
