The origin and understanding of mass’ calculation

                        We let each segment of space-time keep track of how many Quarks and gluons it contains. We then treat these segments as an assembly of interacting subsystems.

                        In this context “we” means a collection of hard-working CPU’s of a large number of powerful computers in sync working at teraflop speeds for months at a time.They manage to calculate the mass of Quarks and Gluons.

                       

                        Quarks are subject, in particular, to Heisenberg’s Uncertainty Principle, which tries to imply that if you try to pin down their position too precisely, their momentum will be wildly uncertain. To support the possibility of large momentum, they must acquire large energy. In other words, it takes work to pin Quarks down. Wavicles want to spread out. So there is a competition between two effects. To cancel the color change completely we would like to put together the quark and antiquark  at precisely the same place; but those wavicles resist localization, so the cancellation comes at a price.

                        A number of stable compromise solutions can be found, where the quark and the antiquark (or three quarks) are brought close together but not perfectly coincident. Their distribution is described by Quantum mechanical wave functions. Each possible stable wave-patterns corresponds to – indeed, in a profound sense  it is --  a different kind of particle that you can observe. There are patterns for protons and neutrons, and for each entry in our whole Greek and Latin smorgasbord. Each pattern has some characteristic energy, because the color fields are not entirely cancelled and because the wavicles are somewhat localized. And that energy, through Einstein’s m=E/c²,  is the origin of mass.

CONCLUSION: I again emphasize that our understanding of mass is not complete still. The value of the electron mass, in particular, remains deeply mysterious even in our most advanced speculations about the grand unification of fundamental forces and string theory.
