[Homework]2012-03-19 阿尔伯特·爱因斯坦 Einstein—3

People didn't believe in atoms in those days but he prove that atoms can actually make small das particles move in the liquids and he calculated the size of atoms.These papers would have done a remarkable career for any physicist but Einstein is far from finished.He writes on another paper which the famous equation E=mc2.At the simplest level,this means energy can become matter and matter can become energy.A tiny spacle of matter hold potentially huge amount of energy.Unleashing requires nuclear reaction.The thought going on constantly in the night sky.Ever since people begin to look up in the heavens,they would say what makes the star shine?But it's Albert Einstein to answer the question,mass(M) turns to E(energy).That is the engine that lights up the stars.Today E=mc2 is Einstein's most famous equation,but the other theory he published in the same year is more important and more controversy,the special theory of relativity.When Einstein was an teenager,he enjoyed imagining what would be like to ride a beam of light.Now he returns to this daydream and changes his life.In the spring of 1905,Einstein was writing on a bus say he look back at the famous clock tower that dominate Bern,Swissland.And then he imagine what happen if that bus reaches the speed of light.In his imagination,Einstein look back at the clock tower and what he sees is astonishing. As he reachs the speed of light,the hands of the clock appear frozen in time.Einstein would later write a storm brought in my mind,all of a sudden,everything,everything  gashingforward.Einstein knows back to the clock tower,time is passing normally.Bt in Einstein's time speed bus,as he reaches the speed of light,the light from the clock can no longer catch up to him.The faster he raises to space,the slower he moves through time.This incite the spark of birth of Einstein's special theory of relativity which says that space and time are deeply connected.In fact,they are one in the same,a flexible fabric called space time.
