Here's an NY Times op-ed piece by the theoretical physicist Sean Carroll of Caltech on the tradition of giving Nobel Prizes to no more than three individuals in any one year, with specific reference to this year's awarding of the Nobel Prize in Physics to François Englert and Peter Higgs without also including other physicists who were instrumental in developing the Higgs mechanism.
No Physicist Is an Island
By SEAN CARROLL
LOS ANGELES — THE physicist Richard Feynman liked to gripe about what he called “Alfred Nobel’s Other Mistake.” The first mistake was the invention of dynamite. The second was creating theNobel Prizes. Mr. Feynman thought it was ridiculous that something as material as a cash prize should be awarded to something as grand and open-ended as scientific research. (The griping wasn’t a matter of sour grapes; Mr. Feynman shared a well-deserved prize for physics in 1965.) This year’s physics Nobel has just been awarded to François Englert and Peter Higgs, for what is simply called “the Higgs mechanism.” But while Mr. Englert and Mr. Higgs undoubtedly deserve acclaim, bestowing an award on them alone distorts the nature of modern physics research.
