Albert Einstein was a German-born, Nobel Prize winning theoretical physicist, best known for his prolific contributions to science. His early work can best be summarised in his ' Annus Mirabilis' papers of 1905, where four separate writings in the same year made substantial changes to modern physics and our understanding of space, time and matter. For these 1. He solved a puzzle of the photoelectric effect, i.e. the phenomenon where electrons are emitted when light is shone on an object, by theorising that light existed in discrete quanta, later called 'photons'. 2. He explained the findings of particles appearing to move randomly in liquids, a phenomenon known as 'Brownian Motion', saying that this was due to atoms, too small for the eye to see, colliding with the particles. 3. He was able to reconcile Maxwell's equations on electricity and magnetism with the laws of mechanics by introducing a new theory of ' Special Theory of Relativity ...
