## Higgs & Relativistic

In another thread I asked the question if my mass is comprised of "Higgs Mass" and "Kinetic mass".

Drakkith was nice enough to reply best he could, but wasn't certain.

So yea, that's what Im wondering. Is my mass comprised of higgs and kinetic?
 Yes. The kinetic component is really easy to understand. Basically any energy that is confined looks like mass. Eg, say you had a box with a lot of light inside it bouncing off the walls, it would appear a little heavier. I believe it would be essentially indistinguishable from a little gas in the box, as regards its gravity, inertia and so on (I am assuming perfect reflection off the walls - perhaps a superconductor might achieve this?). Another type of confined energy is the kinetic energy of quarks bound by massless gluons in neutrons and protons, and as well as that all massive particles acquire what appears to be extra mass when they have some sort of other energy. For example, you are slightly heavier than if you were a lower temperature. What we consider mass depends on the resolution we look at really - you have a mass, the electrons and nuclei in you have a different total mass, the nucleons in the nuclei has masses that are a bit different to the nuclei themselves, and then the quarks in nucleons have masses that are way less than the nucleons they make. All the discrepancies are other sorts of energy (energy in bound particles being bound in general, I suppose). So the role of Higgs is to give the quarks and leptons a little mass in this picture.

You could work it out. What you would need to do is work out how many up quarks, down quarks and electrons there are in your body (start from your mass, the fractions of each element, and how many neutrons and protons there are in the common isotopes)

But the simple answer is that most of it is kinetic, simply because electrons are very light, and up and down quarks are a lot lighter than nucleons (look up their masses and those of neutrons and protons to see).

It will seem a lot clearer if you do some of these calculations, I think. Well, except there is quite a lot of uncertainty about quark rest masses.

[Note: remember a proton is two up quarks and a down quark. A neutron is two down quarks and an up quark]
