Albert Einstein was a German-born theoretical physicist. He developed the general theory of relativity, one of the two pillars of modern physics. He is best known for his mass–energy equivalence formula E = mc².
ACCOMPLISHMENT:
Einstein gave the explanation for calculation of Avogadro's number and the size of molecules.
Einstein was the man, who could give a valid explanation to the question, 'why is the sky blue?' in 1910. He put the 'critical opalescence' phenomenon and give explanation regarding the cumulative effect of the scattering of light by each molecule within the atmosphere.
He explained that light energy came in chuncks or quanta, now called 'photons'. This explanation changed the way researchers thought about the nature of light.
He discussed the Brownian motion that helped in proving the existence of molecules.
He also gave forth explanation regarding the dynamics of individual moving bodies.
He explained the nature of space and time.
