In 2005, asteronomer and cosmologists celebteted in style the-100th aniiversary of their annus mirabils:1905.this was the year in which albert einstein wriote a set of scientific papers including the one containing the equation E=MC2 that changed the understanding of universe and became the corner stone of quantom mechanics and general reality-the twin intellectualpinnacles of the 20th centuary.not bad for a 26-years-old patient office clerk. you cab therefore understand what can all the fuss was about.journals, biographies, exihibition, even plays and operas, were produced to mark the centenary.every utterness, every scrap of papers produced by the great man was eximined and debated in 2005.nothing, surely, could have been left out you ould have thought.certainly, another telling of einstien life story, only a couple of years later must surely seem unnecessary and ambtious. at lsaacson, a formar chief executive of cnn and biographer of both henry kissunger and benjamin franklin, has triumphed over expertation, producing a through exploration of his subject life, a skilfull pice of sceientific litarature and a thumping and a good read. according to lsaacson, we should regard einstein not as an august scientific priest, but as a rebel with reverence for the harmony of nature a scientist who rared omagination higher than knowdge and an individual whose motto, atleast in his eairly year, was long live impudence it is my guardian angel.
