The now obsolete plum pudding model was the first scientific model of the atom with internal structure. It was first proposed by J. J. Thomson in 1904 following his discovery of the electron in 1897 and subsequently rendered obsolete by Ernest Rutherford 's discovery of the atomic nucleus in 1911. The model tried to account for two properties ...

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 plum pudding model of J. J. Thomson also had rings of orbiting electrons. Jean Baptiste Perrin claimed in his Nobel lecture [4] 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. [5]
Rutherford scattering or Coulomb scattering is the elastic scattering of charged particles by the Coulomb interaction. The paper also initiated the development of the planetary Rutherford model of the atom and eventually the Bohr model. Rutherford scattering is now exploited by the materials science community in an analytical technique called ...
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 ...
