These particles make up all visible matter in the universe. • Every high energy physics experiment carried out since the mid-20th century has eventually yielded findings consistent with the Standard Model. • Still, the Standard Model falls short of being a complete theory of fundamental interactions because it does not include gravitation, dark matter, or dark energy. It is not quite a complete description of leptons either, because it does not describe nonzero neutrino masses, although simple natural extensions do. • • http://en.wikipedia.org/wiki/Standard... • --- • UP QUARKS • The particle itself is a fundamental particle and is too small to be seen by any imaginable instrument of observation. So we instead represent the properties that allow the up quark to interact. • The central small dot represents the weak charge of the up quark. This charge entirely separate from electric charge gives rise to the Weak Nuclear Force. This force causes up quarks and down quarks to swap flavours and its typical range is much smaller than the diameter of a proton. • Surrounding that is a volume depicted as gold for the up quark. This represents the electric charge of the up quark, which has a positive charge of +2/3 units The electric charge is the generator of the Electromagnetic Force which has infinite range although the drop off in strength is pretty dramatic as we move away from the quark. • The larger volume of shifting red, green, and blue is meant to represent the color charge which generates the Strong Nuclear Force. This is the force that holds quarks together in a proton or neutron. And a residuum of this force holds the protons and neutrons together in the nucleus of atoms. This force is a hundred times stronger than the Electromagnetic force, but its range is limited to about the size of a proton. • DOWN QUARKS • The particle itself is a fundamental particle and is too small to be seen by any imaginable instrument of observation. So we instead represent the properties that allow the down quark to interact. • The central small dot represents the weak charge of the down quark. This charge entirely separate from electric charge gives rise to the Weak Nuclear Force. This force causes the down quark to change into an up quark, and its typical range is much smaller than the diameter of a proton. • Surrounding that is a volume depicted as purple for the down quark. This represents the electric charge of the down quark, which has a negative charge of -1/3 units The electric charge is the generator of the Electromagnetic Force which has infinite range although the drop off in strength is pretty dramatic as we move away from the quark. • The larger volume of shifting red, green, and blue is meant to represent the color charge which generates the Strong Nuclear Force. This is the force that holds quarks together in a proton or neutron. And a residuum of this force holds the protons and neutrons together in the nucleus of atoms. This force is a hundred times stronger than the Electromagnetic force, but its range is limited to about the size of a proton. • --- • The Cassiopeia Project - making science simple! • The Cassiopeia Project is an effort to make high quality science videos available to everyone.
