2. In comes a noble prize winner; everyone wants to speak to him.The physicists crowd around him. The noble laureate is not free to move around; he has gained inertia by interacting with the crowd.

This is analogous to how the particles acquire mass: by interacting with the Higgs field. Laureates of different popularity gain different masses.

The clustering of the field of physicists is as if a new massive particle has formed. This is the Higgs boson.
