  2. Rutherford model - Wikipedia

    en.wikipedia.org/wiki/Rutherford_model

    The Rutherford model was devised by Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson 's plum pudding model of the atom was incorrect. Rutherford's new model [1] for the atom, based on the experimental results, contained new ...

  3. Rutherford scattering experiments - Wikipedia

    en.wikipedia.org/wiki/Rutherford_scattering...

    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 ...

  4. Plum pudding model - Wikipedia

    en.wikipedia.org/wiki/Plum_pudding_model

    Gold was their preferred material because gold is very malleable and can therefore be made into an especially thin foil. They found that the gold foil could scatter alpha particles by more than 90 degrees. This should not have been possible according to the Thomson model: the scattering into large angles should have been negligible.

  5. Discovery of the neutron - Wikipedia

    en.wikipedia.org/wiki/Discovery_of_the_neutron

    Now called the Rutherford gold foil experiment, or the Geiger–Marsden experiment, these measurements made the extraordinary discovery that although most alpha particles passing through a thin gold foil experienced little deflection, a few scattered to a high angle. The scattering indicated that some of the alpha particles ricocheted back from ...

  6. 5 tiny gold foil figures have been found at a temple in Norway

    The tiny pieces — intricately detailed gold foil figures discovered during excavations of a pagan religious temple — are a rare find in Norway. The country has only 10 known sites, and Hov has ...

    en.wikipedia.org/wiki/Multi-layer_insulation

    The metal coated plastic layers and the scrim separator are visible. Multi-layer insulation ( MLI) is thermal insulation composed of multiple layers of thin sheets and is often used on spacecraft and cryogenics. Also referred to as superinsulation, [1] MLI is one of the main items of the spacecraft thermal design, primarily intended to reduce ...

    Ernest Rutherford. Ernest Rutherford, 1st Baron Rutherford of Nelson, OM FRS HonFRSE [7] (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", [8] and "the greatest experimentalist since Michael ...
