  • 1904: American physicist and academic J. Robert Oppenheimer born. His achievements in physics will include the Born–Oppenheimer approximation for molecular wavefunctions, and the first prediction of quantum tunneling. Oppenheimer will be called the "father of the atomic bomb" for his role in the Manhattan Project.
