Yet three people at most can share a Nobel Prize, a rule that critics say is too restrictive. Winners of the Nobel Prize in physics join a rarefied group that counts Einstein, Marie Curie and Niels Bohr as members. The Nobel Prize in chemistry will be announced Wednesday, the literature prize Thursday and the peace prize Friday.
