Ernest Rutherford, along with his assistants Hans Geiger and Ernest Marsden, set out to test this theory. What they found instead completely upended physics. Working at the University of Manchester, Rutherford’s team aimed a beam of alpha particles (positively charged helium nuclei) at an extremely thin sheet of gold foil. Aparichit Filmyzilla Access
Before 1911, the prevailing scientific model of the atom was the "Plum Pudding Model," proposed by J.J. Thomson. Thomson had discovered the electron and theorized that atoms were composed of a diffuse cloud of positive charge (the pudding) with negatively charged electrons (the plums) scattered throughout.

This discovery laid the groundwork for to later develop the Bohr model of the atom and for the eventual development of quantum mechanics.
