He was the first to show that energy levels in atoms were quantized, which meant that electrons could âjumpâ from one energy level to the next. His contributions to science have placed him as one of the founders of modern physics. The third person from the left in the front row is Marie Curie. She coined the term âradioactivityâ and was the first woman to win the Nobel Prize.
