The plum pudding model is an obsolete scientific model of the atom. It was first proposed by J. J. Thomson in 1904 [1] following his discovery of the electron in 1897 and subsequently rendered obsolete by Ernest Rutherford 's discovery of the atomic nucleus in 1911. It was the first model to describe an internal structure for the atom.
The plum pudding model of J. J. Thomson also had rings of orbiting electrons. Jean Baptiste Perrin claimed in his Nobel lecture that he was the first one to suggest the model in his paper dated 1901. But in actuality the Northern Irish physicist, Joseph Larmor, created the first solar system model of the atom in 1897.
Sir Joseph John Thomson OM FRS [1] (18 December 1856 – 30 August 1940) was a British physicist and Nobel Laureate in Physics, credited with the discovery of the electron, the first subatomic particle to be found.
The experiments were performed between 1906 and 1913 by Hans Geiger and Ernest Marsden under the direction of Ernest Rutherford at the Physical Laboratories of the University of Manchester. The most crucial of these experiments was performed in 1909, being the one where they discovered angles of scattering greater than 90 degrees.
Christmas pudding is sweet, dried-fruit pudding traditionally served as part of Christmas dinner in Britain and other countries to which the tradition has been exported. It has its origins in medieval England, with early recipes making use of dried fruit, suet, breadcrumbs, flour, eggs and spice, along with liquid such as milk or fortified wine ...
William Wallace Denslow ’s illustration of the rhyme, 1902. " Little Jack Horner " is a popular English nursery rhyme with the Roud Folk Song Index number 13027. First mentioned in the 18th century, it was early associated with acts of opportunism, particularly in politics. Moralists also rewrote and expanded the poem so as to counter its ...
Duff (dessert) Duff is a Bahamian cuisine dessert dish made with fruit (especially guava) in a dough. [1] Fruit is folded into the dough and boiled, then served with a sauce. Ingredients include fruit, butter, sugar, eggs, nutmeg, cinnamon, cloves, flour, rum, pepper, and baking powder. Duff is also an English term for pudding.
The vortex theory of the atom was a 19th-century attempt by William Thomson (later Lord Kelvin) to explain why the atoms recently discovered by chemists came in only relatively few varieties but in very great numbers of each kind. Based on the idea of stable, knotted vortices in the ether or aether, it contributed an important mathematical legacy.
