The Indian who made Big Bang test necessary Sep 10, 2008
Einstein had already won the Nobel in 1921 for services to theoretical physics and the discovery of the law of the photoelectric effect, and Fermi won it in 1938. Decades later, in 1964, the British scientist Peter Higgs returned from a walk in the Scottish mountains to tell his colleagues that he had just experienced his one big idea, which could hold a clue to how matter in the universe got its mass in the billionth of a second after the Big Bang.

Biography of Philipp Lenard Sep 3, 2008
Nobel Physicist Famous for his Photoelectric Effect Investigation ... (1862 - 1947) was a German-Hungarian physicist best known for his study of cathode rays and his investigation of the photoelectric effect ... Starting in 1899 Lenard investigated why the photoelectric effect could only be produced by ultraviolet or shortwave light. (Suite101.com)
Louis de Broglie, Physicist Mar 20, 2008
De Broglie was so influenced by Albert Einstein's work on quantum mechanics, in particular, the photoelectric effect showing that waves can behave as particles. In essence, de Broglie's theory destroyed the traditional distinction between waves and particles. (Suite101.com)
The Photoelectric Effect is Solved Mar 17, 2008
The second problem that had been proposed during these years was that concerning the photoelectric effect, wherein light waves fired toward certain metals at differing energies caused the production of free electrons to jump off the material ... He found that there is absolutely no problem at all in the photoelectric effect, if one assumes that Planck is correct after all, and that light is firmly quantized ... If so, in the case of the photoelectric effect, as the light intensity increases,... (Suite101.com)
Max Planck and Light Quanta Mar 16, 2008
Of the two major problems found near the end of the nineteenth century regarding the classical understanding of electromagnetism (that is, light) The Ultraviolet Catastrophe of black-body radiation and the photoelectric effect the former was solved first, in 1900. That very appropriate year the first of the new century marked an important turning point in theories of physics. (Suite101.com)

The Discovery of the Neutron Feb 28, 2008
For instance, he could tell that the mysterious radiation in question was neutral due to the fact that it was not affected by proximity to a magnetic field, and, unlike standard gamma radiation, did not invoke the photoelectric effect (when photons, such as gamma rays, strike certain surfaces, they discharge electrons, which can be simply measured), but rather discharged protons, which meant that the particles had to be more massive than previously expected. In the end, Chadwick finally solved... (Suite101.com)

TommyTutone wrote on Dec 5, 2007 3:50 PM:" I agree totally, it's just hard to take someone seriously when they aren't dressed nicely. I don't believe in Einstein's explanation of the photoelectric effect because he was such a slob. ". dohbaugh wrote on Dec 5, 2007 5:23 PM:" Einstein worked in a lab setting and wasn't a role model for kids.

Are we running out of 'alternative' energy sources? Nov 8, 2007
Solar energy is usually produced by using a solar cell or photovoltaic (PV) cell; a device that converts light into electricity using a photoelectric effect. As a tropical country, Indonesia enjoys sunshine for almost the entire year, providing the country with an abundant source of solar energy. (Jakarta Post, Indonesia -- Business)

Does tenure need to change? Jul 10, 2007
Is it any wonder that Einstein said that he would never have been able to do the work he did on relativity and the photoelectric effect had he gotten a job in academia. They would have kept him too busy on other things, and would not have appreciated his going against the conventional wisdom of his times. (The Scientist)

Albert Einstein: I feel that this one was under the category of making the nobel prize look good; and, Einstein did not receive the prize for his greatest achievements. I admit that his explanation for the photoelectric effect was a landmark that changed physics, but his prize did not acknowledge his... (Lodi News Sentinel, CA)

"(I'll use) an example of a paper Einstein wrote in 1905 ... on photoelectric effect," he said. "This was an obscure observation that was made in the late 1800s and Einstein explained what was happening. Particles of light were hitting metal films and out came electrons. It was some strange phenomenon that nobody quite understood and nobody quite knew what to do with. (Today) it's the thing that happens in all the cameras that we have and our entire electronics industry is based on that... (Black Hills Pioneer, SD)
A glimpse at personal side of Einstein Feb 5, 2007
" He would never again be so poor, nor so vulnerable, as he was in the spring, summer and fall of 1915. Albert Einstein met Mileva Maric at the Zurich Federal Institute of Technology in 1896, when he was 17. He was the bright young student who cut class and didn't much care for the antiquated ideas of his professors. Maric was three years older, walked with a limp, was too brainy and wasn't Jewish. They fell in love, but his parents didn't like her. The couple was independent-minded and... (San Francisco Chronicle)
