n 1905, at the age of 26 and four years before he was able to get a job as a professor of physics, Einstein published five of the most important papers in the history of science--all written in his "spare time." He proved that atoms and molecules existed. Before 1905, scientists weren't sure about that. He argued that light came in little bits (later called "photons") and thus laid the foundation for quantum mechanics. He described his theory of special relativity: space and time were threads in a common fabric, he proposed, which could be bent, stretched and twisted.
Before Einstein, the last scientist who had such a creative outburst was Sir Isaac Newton. It happened in 1666 when Newton secluded himself at his mother's farm to avoid an outbreak of plague at Cambridge. With nothing better to do, he developed his Theory of Universal Gravitation.
For centuries historians called 1666 Newton's annus mirabilis, or "miracle year." Now those words have a different meaning: Einstein and 1905. The United Nations has declared 2005 "The World Year of Physics" to celebrate the 100th anniversary of Einstein's annus mirabilis. (Nobel prize winners and other top scientists will meet with the public next month to discuss Einstein's work. Would you like to join them?)
Modern pop culture paints Einstein as a bushy-haired super thinker. His ideas, we're told, were improbably far ahead of other scientists. He must have come from some other planet--maybe the same one Newton grew up on.
"Einstein was no space alien," laughs Harvard University physicist and science historian Peter Galison. "He was a man of his time." All of his 1905 papers unraveled problems being worked on, with mixed success, by other scientists. "If Einstein hadn't been born, [those papers] would have been written in some form, eventually, by others," Galison believes.
