  While QCD can provide corrections to the parton distribution function, it
cannot produce the distribution. Where is then the starting point for the
proton structure function? The only known source is the quark-model wave
function for the proton at rest. The harmonic oscillator is used for the trial
wave function. When Lorentz-boosted, this wave function exhibits all the
peculiarities of Feynman's parton picture. The time-separation between the
quarks plays the key role in the boosting process. This variable is hidden in
the present form of quantum mechanics, and the failure to measure it leads to
an increase in entropy. This leads to a picture of boiling quarks which become
partons in their plasma state.
