Processes

Solar clocks are like this radiant icon.

Let particle P be described by a historically ordered chain of events  \Psi. Consider some pair of events  \mathsf{P}_{i} and  \mathsf{P}_{f} from the sequence

\Psi^{\mathsf{P}} = \left( \mathsf{P}_{1}, \mathsf{P}_{2}, \mathsf{P}_{3} \, \ldots \, \mathsf{P}_{i} \, \ldots \, \mathsf{P}_{f} \, \ldots \, \right)

Since  \Psi is in historical order we call  \mathsf{P}_{i} the initial event and  \mathsf{P}_{f} the final event of the pair. If these events always have the same quark coefficients  n, for each sort of quark  \mathsf{q}, then we say that P is isolated. But if they are not all the same, then we say that P has undergone an interaction with some other particle generically called  \mathsf{X}. Recall that quarks are conserved. So each kind of interaction implies a specific relationship between quark coefficients. Some possibilities are shown in the following table.

Thermodynamic Processes
InteractionCoefficients βˆ€ q
isolation  \mathsf{P}_{i}  \to \mathsf{P}_{f}   n^{\mathsf{q}} \left( \mathsf{P}_{i} \right) = n^{\mathsf{q}} \left( \mathsf{P}_{f} \right)
emission \mathsf{P}_{i}  \to \mathsf{P}_{f} + \mathsf{X}    n^{\mathsf{q}} \left( \mathsf{P}_{i} \right) = n^{\mathsf{q}} \left( \mathsf{P}_{f} \right) + n^{\mathsf{q}} \left( \mathsf{X} \right)
absorption  \mathsf{P}_{i} + \mathsf{X}  \to \mathsf{P}_{f}   n^{\mathsf{q}} \left( \mathsf{P}_{i} \right)  + n^{\mathsf{q}} \left( \mathsf{X} \right) = n^{\mathsf{q}} \left( \mathsf{P}_{f} \right)
annihilation  \mathsf{P}_{i} + \mathsf{\overline{P}}_{i}  \to \mathsf{P}_{f}   2N_{\mathsf{q}} \left( \mathsf{P}_{i} \right) = N_{\mathsf{q}} \left( \mathsf{P}_{f} \right)
pair production  \mathsf{P}_{i} \to \mathsf{\overline{P}}_{f}  + \mathsf{P}_{f}   N_{\mathsf{q}} \left( \mathsf{P}_{i} \right) = 2N_{\mathsf{q}} \left( \mathsf{P}_{f} \right)

Thermal Processes
warming    T_{f}    > T _{i}
isothermal    T_{f}   = T _{i}
cooling    T_{f}    < T _{i}
If the events in  \Psi are described by their temperature   T, then any changes are noted by subtracting initial from final values. We write  \Delta T \, \equiv \, T_{f} - T_{i}. Then any thermal changes due to a process can be classified by  \Delta T as indicated in the accompanying table. And so for example we might make a combined description of some process as isothermal absorption, or perhaps cooling by emission etc.

Sensory Interpretation

Processes, both thermal and thermodynamic, are represented by this six sensation icon.

The quarks that are explicitly enumerated in the processes discussed above are named after their thermodynamic seeds. These seeds are in-turn defined by Anaxagorean sensations. So all the foregoing interactions are just detailed, systematic descriptions of thermal, visual and somatic sensations. Thermodynamic processes are objectified ways of recounting changes in what we see, hear and feel.

Processes, both thermal and thermodynamic, are suggested by this sacred weaving from Indonesia.
