Nobel Prize in Physics rendered by the discovery of the remarkable rays (or x-rays). This award is administered by the Nobel Foundation and widely regarded as the most prestigious award that a scientist can receive in physics. It is presented in Stockholm at an annual ceremony on 10 December, the anniversary of Nobel's death. Through 2018, a total of 209 individuals have been awarded the prize. Only three women (1.4% of laureates) have won the Nobel Prize in Physics: Marie Curie in 1903, Maria Goeppert Mayer in 1963, and Donna Strickland in 2018. Alfred Nobel, in his last will and testament, stated that his
