Achievements of Albert Einstein in his life

* Einstein showed that absolute time had to be replaced by a new absolute: the speed of light. Einstein went against the grain and totally dismissed the "Old Physics." He envisioned a world where space and time are relative and the speed of light is absolute (at the time, it was believed that space and time were absolute and the speed of light was relative).

* He asserted the equivalence of mass and energy, which would lead to the famous formula E=mc2

* Einstein challenged the wave theory of light, suggesting that light could also be regarded as a collection of particles. This helped to open the door to a whole new world--that of quantum physics. For ideas in this paper, he won the Nobel Prize in 1921.

* His paper concerning the Brownian motion of particles. With profound insight, Einstein blended ideas from kinetic theory and classical hydrodynamics to derive an equation for the mean free path of such particles as a function of the time.

* Einstein showed how to calculate Avogadro's number and the size of molecules.

* In 1910, Einstein answered a basic question: 'Why is the sky blue?' His paper on the phenomenon called critical opalescence solved the problem by examining the cumulative effect of the scattering of light by individual molecules in the atmosphere.

* Einstein later published a paper in 1915 called "General Relativity." General Relativity took over when Special Relativity started to fail. Controversy started to rise when Einstein released his second paper called "General Relativity."

* In 1917, Einstein published a paper which uses general relativity to model the behavior of an entire universe. General relativity has spawned some of the weirdest, and most important results in modern astronomy.

* Einstein recognized that there might be a problem with the classical notion of cause and effect. Given the peculiar, dual nature of quanta as both waves...
