Ernest Rutherford, 1st Baron Rutherford of Nelson, OM, PRS, HonFRSE (30 August 1871 – 19 October 1937) was a New Zealand physicist who was a pioneering researcher in both atomic and nuclear physics. Rutherford has been described as "the father of nuclear physics", and "the greatest experimentalist since Michael Faraday".
Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure. If Thomson was correct, the beam would go ...
Apr 2, 2014 · A pioneer of nuclear physics and the first to split the atom, Ernest Rutherford was awarded the 1908 Nobel Prize in Chemistry for his theory of atomic structure. Dubbed the “Father of the...
In 1912 Niels Bohr joined him at Manchester and he adapted Rutherford’s nuclear structure to Max Planck ‘s quantum theory and so obtained a theory of atomic structure which, with later improvements, mainly as a result of Heisenberg’s concepts, remains valid to this day.
