where each orbital cycle is a bundle of N seeds

Let each seed be described by its audibility ὲ and its specific energy Ê. We characterize P using a sum over all of these component seeds

Definition: the number U is called the internal energy of P. The internal energy may be positive, negative or zero depending on a particle's composition and some choice for the calorimetric reference sensation.
To establish numerical values for the internal energy, consider a down-quark d for which
If the calorimetric reference sensation is chosen so that a down-seed has the same specific energy as an ordinary conjugate-seed, then

Let us do this consistently so that the down-quark serves as a reference particle for setting the energy null value. The other numbers shown in the accompanying table can be obtained from laboratory observations of nuclear particles. The conventional unit used for reporting these measurements is one million electron-volts abbreviated as (MeV).
Theorem: an ordinary quark and its associated anti-quark have the same internal energy. To see this, consider the generic quarks

By the foregoing definition, the internal energies for these particles are given by

But the hypothesis of conjugate symmetry asserts that

so both quarks have the same internal energy

and we can unambiguously use the quark index to refer to either one.
