Nobel Prize relevant fields was greater), a greater delay in awarding Nobel Prizes for women's achievements making longevity a more important factor for women (Nobel Prizes are not awarded posthumously), and a tendency to omit women from jointly awarded Nobel Prizes. Four people have received two Nobel Prizes. Marie Curie received the Physics Prize in 1903 for her work on radioactivity and the Chemistry Prize in 1911 for the isolation of pure radium, making her the only person to be awarded a Nobel Prize in two different sciences. Linus Pauling was awarded the 1954 Chemistry Prize for his research into the chemical
Nobel Prize controversies Chen-Ning Yang—by providing him in 1956 with a possible test method for beta decay that worked successfully. Her book "Beta Decay" (1965) is still a sine qua non reference for nuclear physicists. Several Nobel Prizes were awarded for research related to the concepts of the boson, Bose–Einstein statistics and Bose–Einstein condensate—the latest being the 2001 Nobel Prize in Physics given for advancing the theory of Bose–Einstein condensates although Satyendra Nath Bose himself was not awarded the Nobel Prize. In his book "The Scientific Edge", physicist Jayant Narlikar observed: "SN Bose's work on particle statistics (c.1922), which clarified the behavior of
