| THE 2006 SOLAR ECLIPSE AND THE EINSTEIN YEAR |
|
In 2005 the world celebrated the International Year of Physics (original labeled the World Year of Physics) in honour of Einstein's “annus mirabilis” of 1905. In that year, in less than seven months, Einstein wrote five history- making papers. He proposed the particle theory of light (the photoelectric effect), developed a method to measure molecular dimensions, explained the long- puzzling Brownian motion, developed the theory of special relativity, and finished his intellectual sprint by producing the world's most famous equation E = mc2- (taken from John and Rigden's article in Physics World, April,2005).
Although Einstein's year has been celebrated we in the Physics community and indeed the World are still actively savoring the memories of great Einstein. In March 2006, a solar eclipse will occur and we in West African will be able to watch it. The forthcoming even is yet another reminder of Einstein's genius. We are reminded of his great work on; General Principle of Relativity—pushed in 1915. As wheeler, then giant America physicists put it. Einstein became a celebrity after the 1919 solar eclipse.
Einstein had predicted that light passing near a massive object like the sun world deflected by an amount given by his new theory of gravity (the general theory of relativity). The proof of this theory was from photographs of stars taken from the Island of Principe, here on the West Coast of Africa. In that year, the solar eclipse provided the needed opportunity for a British expedition led by another great scientist, Arthur Edington to test Einstein's predict. Edington compared the photographs of stars from the Hyades star cluster, seen in the vicinity of the eclipsed sun, with photographs of the same stars when the sun was off the visual field. The photographs confirmed the predicted shift in the star apparent position. |
