English: Bare masses of all 6 flavors of w:quarks, proton and electron in comparison, as balls of proportional volumes. Under magnification one can see a blurry boundary of u quark, which demonstrates a large uncertainty about its mass. Proton and electron (red) are shown in bottom left corner for scale.
Français : Masse des 6 saveurs de quarks, en comparaison avec le proton et l'électron, représentés par des sphères aux volumes proportionnels. Le quark u (up) est gris parce qu'on n'est pas certain de sa masse. Le proton et l'électron (rouge) sont affichés à l'échelle dans le coin inférieur gauche.
English: Note:
A ball of 1px radius (in internal coordinates) corresponds to 1 MeV/c2 mass. 1px of internal coordinates maps to 4 pixels in the default resolution of 448×448.
