Latest Wave–particle duality Stories
Physicists are divided on whether string theory is a viable theory of everything, but many agree that it offers a new way to look at physical phenomena that have otherwise proven difficult to describe.
A sensitive measuring device must not be dropped - because this usually destroys the precision of the instrument.
EDINBURGH, Scotland, Dec.
A hundred years ago, we took the first steps in recognising, at the level of elementary physical events, the dual character of nature that had been postulated in natural philosophy. Albert Einstein was the first who saw Max Planckâ€™s quantum hypothesis leading to this dual character. Einstein suggested the photon have an electromagnetic wave character, although photons had previously been considered as particles. That was the quintessence of his work on the photoelectric effect. Later...
In 1921 Einstein won the Nobel Prize not for his work on relativity, but for solving a puzzle that had baffled scientists since 1887 -- the photoelectric effect. In one of the three ground-breaking papers he published in 1905 he explained it in one astonishing blow: the light is quantized. His work was the first step in launching quantum theory.
He stopped traffic on Fifth Avenue like the Beatles or Marilyn Monroe. He could've been president of Israel or played violin at Carnegie Hall, but he was too busy thinking. His musings on God, love and the meaning of life grace our greeting cards and day-timers. Fifty years after his death, his shock of white hair and droopy mustache still symbolize genius. Who else could it be but Albert Einstein?
