Science Datebook: March 11 Baron Ernest Rutherford, Father of Nuclear Physics
Baron Ernest Rutherford (b. August 30, 1871-d. October 19, 1937), was a New-Zealand born British physicist. This day on March 11, 1911, Ernest Rutherford is considered the father of nuclear physics, as he published his atomic theory describing the structure of the atom for the first time at the Manchester Literary and Philosophical Society.
He described the atom as having a central positive nucleus surrounded by negative orbiting electrons. His model suggested that most of the mass of the atom was contained in the small nucleus, with the rest of the atom mostly empty space. His conclusion followed what we now know as Rutherford's "gold foil experiment" especially amongst science students and other advocates.
Ernest Rutherford was awarded the 1908 Nobel Prize in Chemistry "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances."
To honour and remember Baron Ernest Rutherford for his significant contribution to science, we share this video produced by Science and Technology Facilities Council. The chemical element 104, Rutherfordium, was named after him in 1997.
