Lord Rutherford and the Atomic Pudding
Today is the 100th anniversary of the publishing of Ernest Rutherford's revolutionary article, "The Scattering of α and β Particles by Matter and the Structure of the Atom," which appeared in Philosophical Magazine (Series 6 21: 669-688). In the article, Rutherford explained his astonishing and profound discovery that atoms consist of a small and dense nucleus surrounded by electrons.
