His thinking on God, love and the meaning of life grace our greeting cards and day-timers. Fifty years after his death, his shock (蓬乱) of white hair and hanging mustache still symbolize genius. Einstein remains the foremost scientist of the modern time. Looking back 2,400 years, only Newton, Galileo and Aristotle were his equals. Around the world, universities and academies (研究院) are celebrating the 100th anniversary of Einstein's "miracle year" when he published five scientific papers in 1905 that basically changed our grasp of space, time, light and matter. Only he could top himself about a decade later with his theory of relativity. Born in the age of horse-drawn carriages, his ideas launched a technological revolution that has made more change in a century than in the previous two thousand years. Computers, satellites, telecommunication, lasers, television and nuclear power all owe their invention to ways in which Einstein exposed a stranger and more complicated reality underneath the world． He escaped Hitler's Germany and devoted the rest of his life to human rights and peace with an authority unmatched by any scientist today, or even most politicians and religious leaders. He spoke out against fascism (法西斯主义) and racial prejudice. His FBI (美国联邦调查局) file ran 1,400 pages. His letters expose a disorderly personal life -- married twice and indifferent toward his children while absorbed in physics. Yet he charmed lovers and admirers with poetry and sailboat outings. Friends and neighbors fiercely protected his privacy.
