Light is a distribution of the probability of detecting photons. Photons are particles that are formed by strings of equidistant energy packages. Each of these energy packages is a one-dimensional shock front that travels in our living space. This field is not the electromagnetic field.

Heat is the kinetic energy of an ensemble of particles. In general these particles need not be charged electrically.

Sound is a vibration of a coherent ensemble of particles.

You are joking about the theologians right?description Sound is essentially mecahnical energy in the medium.

In a word: inertia.

Dear Dr. Satsangi. The second quantization formalism of the EM field is able to convert Photons in quasiparticles with not mass using creation and destruction operators. I do not know about second quantized formalism creating or destruying heat waves treated at least from a semic classic approach in solid state physics. However there are spin waves, sound longitudinal waves, helicons, excitons, polarons, rotons (superfluidity), polaritons and other more complicated examples. Respect to Phonons the question is subtle. There are longitudinal phonons with zero spin and no mass as well with the same second quantization formalism as the one for transversal photons for the EM field (non relativistic case - London Book). These phonons (harmonic and anharmonic approx.) are the ones used since the beginning of QT (Quantum Theory) for Physics and Chemistry. But respect to transversal phonons the question is just a subtle mistery. A paper from 1962 wrote the following words:

"In any case, it is a quantity of fundamental interest that must be considered in any program of quantization". (This author was refering to the spin of the phonon).

Don´t be surprised if soon appears a new field called Phononics where the question will be addressed correctly. There are some papers from the 80 and 90 about the excitations of temperature waves in the skin layer of a metal as a secondary effect due to the incidence of an EM. Heat and Energy has a intermediate friendly irreversible effect: Dissipation.

It is a fundamental question and probably should be anwered using symmetry considerations of the kinetic coefficients (already done) but again a missing paper . Centairly I do not understant completely the interpretation of the first thermodynamic principle using probabilities as given in several textbooks.

Dear Dr. Don´t be surprised if soon appears a new field called Phononics where the question will be addressed correctly. Regards. Pedro L.

Thanks Dear Dr. Pedro for a highly enlightening response. Certainly we should wait for a new field Phononics.

My Pleasure Dear Professor Satsangi

According to Hindu Philosophy tanmatra is the subtle form of element. Tanmatra is the Sanskrit term which comes from the root words, tan, meaning 'subtle', and matra, meaning 'element. Sound is akash tattwa (element) which is known in English as ether. Gravitation Force is the subtlest state of akash (ether). This description is according to Hindu Philosophy particularly Philosophy of Radhasoami Faith.

Except there is no ether. When science and religion clash...religion loses. These may be senstive and beautiful descriptions, and contain some wisdom, but like phlogiston and the philosopher's stone, do not exist.

I think religion never loses.

So the fundamental reason for physics is "God willed it".

Sometimes I feel Einstein was more a religious philosopher than a physical science theorist. In 1896, the year Einstein entered into Swiss University, Swami Vivekananda delivered his class talks on Vedanta Philosophy in New York. In one of his talks he mentioned about 'Eternal Changeability of Prakriti (Nature)'. Perhaps this thought of Vivekananda might have given the way to Einstein to develop a theory of Law of Conservation of Mass and Energy and to give a very famous formula E = mc^2.

E=mc^2 came from special relativity, not a conservation of energy theory.

It explains conservation of mass and energy.
