Session 10 of Course 14

Photons go away from the locus of those electrons that form these -- once that the corresponding electrons drop an energy level in so as to form the said photons.  When photons form, these are brought to into the direct vicinity of other photons in such a manner is so that these work to coallece into one one or more beams of light -- depending on whether one is here considering one or more groups of photons that respectively quantize into one or more beams of the eluded to electromagnetic energy.  One of the main properties that causes photons to coallece is the condition of the whole-spin of the individual photons that work to quantize -- in a discrete manner -- into beams of electromagnetic energy, primordially, light.  The angular momentum, spin-orbital momentum, and, the specific parity of any set of respective photons -- relative to one another -- works to bring certain relatively local photons together with each other in so as to allow these said photons to coallece into a beam.  The just mentioned coalleceing, or, the eluded to quantization that I have just described, works to make each photon that comrpises any corelative beam that such phenomena come together to form, to act as both an individual photon, &, also as the whole beam of the corresponding electromagnetic energy, at the same time.  The said quantization of light brings light together into beams of light -- while, in other arbitrary cases, this said general condition of quantization, often, in many cases, works to bring certain beams of light into a larger scope of electromagnetic energy that would here work to form a wider "arena" of the relatively proximal electrodynamics that exists in a given arbitrary general region of kinematic-based space-time-fabric.  Photons travel in a straight line in a vacumm. -- In so far as space-time may be considered as relatively "straight" in a limited distance in which such a detectable extrapolation may be determined.  I put it that way, on account of the condition that space-time-fabric actually tends to curve over a much larger extrapolation-based distance.  The electric fields of beams of photons do not fluctuate in a straight line.  The just mentioned fluctuation of the said electric field of a beam of light is the wavelength of that said beam of light.  White light fluctuates to less of a degree in its electric field than infrared electromagnetic energy.  A strong laser fluctuates to less of a degree in its electric field than the said white light.  Photons that have complementary spin, angular momentum, spin-orbital momentum, and directoral parity, will tend to coallece with each other to form a specific form of electromagnetic energy.  When photons with a different spin, angular momentum, spin-orbital momentum, and/or directoral parity, are directed toward each other, theses will scatter until these reach a basis of complementary flow -- once the directly corresponding photons scatter into a genus of a relatively common spin, angular momentum, spin-orbital momentum, and directoral parity -- in so as to quantize as an overall beam.  Sam.
