Nobel Prize

  The Nobel Prize in Physics 2004             The theory shows its true colours The aftermath of a high-energy collision between a proton and an electron, as seen by the H1 experiment at the DESY laboratory in Hamburg. The experiment is shown in cross-section, perpendicular to colliding beams of protons…

  The Nobel Prize in Physics 2004         Inside the proton The three quarks within the proton are held together by the powerful force mediated by the gluons, depicted here as coiled springs. As the distance between the quarks increases, so does the force between them.   Contents: |  |  |   |  |  |  |  |  | |  …

  The Nobel Prize in Physics 2004             The strong force Many tried but failed, to find a theory in which the strength of the strong force decreases as the energy increases. This year’s Nobel Laureates produced a theory with the required minus sign.       Contents: |  |  |   |  |  |  | …
