How does your handkerchief get a mass?* > The mass of the electrons and quarks in the handkerchief come from the Higgs field but if you add it all up it that only amounts to about 1% of the mass of the handkerchief. The remaining 99% comes from the strong force binding energy that keeps quarks inside of protons and neutrons, although many of the details remain unclear and this area is on the frontier of modern physics research.
