By Little, Joseph This article examines the role of the liquid drop analogy in George Gamow's theory of nuclear structure and his subsequent derivation of nuclear energy. It argues that the correspondences constituting the analogy served distinct but cooperative ends, requiring Gamow to posit a relatively simple nuclear geometry that set him apart from his contemporaries, mostly shell theorists, and led to his successful derivation of nuclear energy in the fall of 1928. Analogy has long...

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 Planck'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...

WASHINGTON -- How does a flower know when to, well, flower? For one thing, it isn't just April showers that do the trick. After all, some forsythia burst forth in early spring, roses enjoy the summertime and there are types of rice that flower in the fall. Scientists have long known that it is the amount of sunshine that makes the difference. Now they have figured out how the leaves signal the flowers to form. A series of papers by German, British, Swedish and Japanese researchers details...

IOP -- 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. Today (Friday 29th April 2005) New Journal of Physics (NJP) published a special celebratory focus issue containing a series of new...

One hundred years ago, Albert Einstein revolutionized physics. Science@NASA -- Albert Einstein was exhausted. For the third night in a row, his baby son Hans, crying, kept the household awake until dawn. When Albert finally dozed off "¦ it was time to get up and go to work. He couldn't skip a day. He needed the job to support his young family. Walking briskly to the Patent Office where he was a "Technical Expert, Third Class," Albert worried about his parents. They were getting older...
