2015 Nobel Prizes

The 2015 Nobel Prizes were awarded by the Nobel Foundation, based in Sweden. Six categories were awarded: Physics, Chemistry, Physiology or Medicine, Literature, Peace, and Economic Sciences.^[1]

Nobel Week took place from December 6 to 12, including programming such as lectures, dialogues, and discussions. The award ceremony and banquet for the Peace Prize were scheduled in Oslo on December 10, while the award ceremony and banquet for all other categories were scheduled for the same day in Stockholm.^[2][3]

Reactions

Physics

While the Physics Prize was not inherently disputed, some scientists discussed whether the Nobel Foundation's written citation for Kajita and McDonald's awarding was correct, leading to a technical debate about the definition of a "neutrino oscillation" and whether their experiments showed such a phenomenon.^[10]

Physiology or Medicine

During the COVID-19 pandemic, the awarding of Ivermectin was sometimes invoked in order to justify the medication's usage as a treatment for the Coronavirus. However, Campbell and Ōmura had been awarded for Ivermectin's effectiveness specifically against parasitic infections.^[11]
