A Reaction

As an outsider all I can do is collect descriptions of such properties from the experts. The experts appear to be happy with the numbers inserted in the equations.


The 11 ideas with the same theme [features found in various particles]:

Experiments show that fundamental particles of one type are identical [Farmelo]
Eletrons don't literally 'spin', because they are point-like [Martin,BR]
The properties of a particle are determined by its quantum numbers and its mass [Martin,BR]
Virtual particles surround any charged particle [Martin,BR]
Particle measurements don't seem to reflect their reality [Baggott]
Spin is a built-in ration of angular momentum [New Sci.]
Quarks have red, green or blue colour charge (akin to electric charge) [New Sci.]
Fermions, with spin ½, are antisocial, and cannot share quantum states [New Sci.]
Particles are spread out, with wave-like properties, and higher energy shortens the wavelength [New Sci.]
Spin is akin to rotation, and is easily measured in a magnetic field [New Sci.]
Quarks and leptons have a weak charge, for the weak force [Hesketh]
