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
Nobel Prize controversies stated, should be given "to the person who shall have made the most important 'discovery' or 'invention' within the field of physics". Awards committees have historically rewarded discoveries over inventions: 77% of Nobel Prizes in physics have been given to discoveries, compared with only 23% to inventions. In addition, the scientific prizes typically reward contributions over an entire career rather than a single year. No Nobel Prize was established for mathematics and many other scientific and cultural fields. An early theory that jealousy led Nobel to omit a prize to mathematician Gösta Mittag-Leffler was refuted because of timing inaccuracies. Another
