Like all good scientists, Eddington was interested in advancing knowledge through experimentation. General relativity made very specific predictions about what would be observed under certain conditions, and Eddington was one of many people who wanted to test whether these observations were true. When they turned out to be very close to what Einstein predicted, Eddington achieved what all good scientists do -- experimental test of a hypothesis.

What was the key early test of Einstein's General Theory of Relativity?
Einstein described his general relativity (gr) hypothesis in November of 1915. It predicted that the path of light from a distant star would appear to bend* when it passed near to our Sun. Such an effect could only be observed during a solar eclipse, and only with very sensitive instruments. Einstein admitted that a failure to observe the effect EXACTLY as predicted would mean all of gr would have to be abandoned -- there was pretty no "fudge factor" that would permit a modification of his basic idea to meet experimental results. Einstein was able to show that gr explained an anamalous precession of the perehelion of Mercury. This was an unexpected early "test" of his hypothesis, but was hardly proof. It simply meant that gr explained a known fact of nature better than other ideas, but that did not mean it was the ONLY possible explanation. The first observational test of light bending -- a test that would unambiguous prove or disprove gr -- was done by Arthur Eddington in 1919 May, and the results, when announced in November of that year, made Einstein a world celebrity literally overnight. More exact observations done in 1922 showed, beyond any dispute, that this bending was exactly as Einstein had predicted. * I say "appear" because, in actuality, space is being warped and the light is simply following the space through which it is traveling.
What day did Albert Einstein invent the laser?
Albert Einstein did not invent the laser, however, he established the theoretical foundations for the laser in 1917. There were actually many scientists who were involved in inventing the laser: Gordon Gould, Charles Townes, Arthur Schawlow, Theodore Maiman, Nikolay Basov, and Aleksandr Prokhorov to name a few.
Why did Albert Einstein stick his tongue out?
On Einstein's 72nd birthday in 1951, UPI photographer Arthur Sasse was trying to persuade him to smile for the camera, but having smiled for photographers many times that day, Einstein stuck out his tongue instead.[1] This photo became one of the most popular photos ever taken of Einstein and it is well recognized in popular culture,[2][3] often used in merchandise depicting Einstein in a lighthearted sense. One of the only known signed photographs of Albert Einstein’s Iconic Act of Playful Defiance has recently (June, 2009) come to market at RR Auction, a signed memorabilia auction house. The complete background of when the photo was originally taken, how Einstein asked for 9 prints for himself. Only one of these photos have emerged to the public eye with his thoughts and signature on it. the history on this particular signed photo was started in 1953, at the height of the 1950s Communist witch-hunt. Albert Einstein signed the photo for award-winning CBS and ABC anchor reporter Howard K. Smith as a gesture of his admiration of Smith’s work. The German inscription (translated) states: “This gesture you will like, Because it is aimed at all of humanity. A civilian can afford to do what no diplomat would dare.” Einstein’s statement clearly shows his keen senses of both humor and defiance. “This photo of Einstein sticking his tongue out captures his spirit of rebelliousness and non-conformity,” said John Reznikoff of University Archives in Westport, Connecticut, when shown the photo. “It is without a doubt the most desirable photo of Einstein I have ever seen.” The photograph was taken by UPI photographer Arthur Sasse on March 14, 1951, following an event at Princeton to honor Einstein on his 72nd birthday. While Sasse tried mightily to convince the physicist to smile for the camera, the reaction he received, recorded forever on film, was humorously unexpected! Einstein was so amused by the image that he contacted UPI and requested nine prints for his personal use. The photo being offered for sale is the one that Einstein gave to Smith, to whom he listened regularly, and is the only one of the nine that has ever been made available for public purchase. The value of the image, with its connection between scientist and newsman, makes it historically significant and gives us insight directly into what Einstein's thoughts were on the image. By 1953, Einstein had boldly begun speaking out against McCarthyism when he wrote a nationally-published letter that stated, “Every intellectual who is called before one of the committees ought to refuse to testify.” That same year, an electrical engineer was called before McCarthy’s committee and refused to testify with the explanation that he was following “advice from Professor Einstein.” Reznikoff believes Einstein knew the risky implication of his now-famous gesture. “You can tell by the inscription that he fully understood the power the image conveyed, and what he was doing was quite dangerous considering the Government was forcing intellectuals to name names.” Marcia Bartusiak , author of Einstein's Unfinished Symphony and The Day We Found the Universe, believes the photo has become such a timeless symbol of non-conformity “because it shows one of history’s greatest men doing something very out of character for what we imagine great figures of history should look like. It’s a jolt to see science’s most familiar face doing something just a bit naughty.”

What did people think of Albert Einstein?
After 1905 he was a respected physicist within the science community. After Arthur Eddington claimed, in 1919, that Einstein's general relativity theory was correct, Einstein became, literally overnight, the most famous scientist in the world.
How did Arthur Eddington prove Albert Einstein's theory of relativity?
Well, to clarify, Eddington proved one aspect of Einstein's Theory of General Relativity. Einstein predicted that light would actually be gravitationally "bent" when passing by a large body with powerful gravity. The only way to test this from earth was to observe a total eclipse with information beforehand of what stars would be visible near the sun at totality. If the light from those stars appeared "nearer" to the sun than it should have been during totality, it was the sun's gravity that was "bending" the light of those stars. Eddington's observations were accurate during the total eclipse of 1919, and it was accepted that he had proved that aspect of General Relativity. But there are many other aspects of General Relativity. Eddington proved oneof them.
What has the author Arthur Eddington written?

When did Arthur Eddington die?
Arthur Eddington died on 1944-11-22.
How did Arthur Eddington contribute to science?
He is famous for his work regarding the theory of relativity. Eddington wrote a number of articles which announced and explained Einstein's theory ofgeneral relativity to the English-speaking world. World War I severed many lines of scientific communication and new developments in German science were not well known in England, and vice versa. He also conducted an expedition to observe the Solar eclipse of 29 May 1919 that provided one of the earliest confirmations of relativity, and he became known for his popular expositions and interpretations of the theory. -wiki

Why did Arthur Eddington chose Albert Einstein's theory?
For a VERY simple reason: Einstein's Theory explained experimental results perfectly, and no other theory did so. That is the basic nature of science.
What has the author Arthur Stanley Eddington written?
Arthur Stanley Eddington has written: 'The nature of the physical world'
Which scientist worked with Einstein to confirm relativity?
It is not so much that another scientist was working with Einstein to confirm the Theory of General Relativity as a great many scientists believed his theory to be Newtonianâ??s theory in a shiny new wrapper. Arthur Eddington led an expedition into Africa to photograph a solar eclipse in the hopes that Newtonian Physics might be validated, but the converse was found to be true and Einstein was shown to be right in his theory and in a great many other theories he produced during his life time.
