Why do people say (my teacher) that physics is the most important out of biology, chemistry and physics?
I think what your teacher (and other people who hold that opinion) mean is that physics is the most Fundamental of the three primary sciences (Biology, Chemistry, Physics)
Physics deals with forces and interactions and the smallest particles of matter (quarks, electrons, etc.).
Chemistry deals with atoms and reactions between them. The exchange of electrons between atoms.
Biology deals with molecules and large structures/systems much more complicated than a physicist could deal with!
A general rule of understanding anything (even something as vast as our universe) is to look at the most fundamental bits. So that is why Physics is important for understanding our universe. That doesn’t mean Chemistry and Biology should be under-rated.
It can now be shown, and understood if you have been following the previous posts, that photons are planar geometries of mass-energy momenta.
Their rhombic [dual-equilateral] electromagnetic fields geometries are comprised of 2 charged bosons [W] that posses sqrt linear momentum causing the photon to radiate in two directions from their point sources.
Any measurement of these energies per second [E/c^2] is a measurement of mass, but as there is NO Z component to 2d planar field geometries [ie no closed topologies] they are in fact MATTER-less fields… or fields of weightless mass-energy momenta.
Their planar rhombic geometries are in fact the result of their quantised angular momenta [the m^2/s of Planck’s constant] and it in turn is NOT a vector rotation about a point [spin] as is taught in modern physics but an equilateral geometry at the quantum scale.
Their ‘spin’ can in fact be modelled as an ideal quantum inductive loop of EM energies [as illustrated] which in turn gives rise to the physics and properties of inertial mass.
Their rhombic dual charge field geometries give rise to the sinusoidal orthogonal electromagnetic waveforms associated with EM waves and photons alike.
And they are completely unaffected by Gravity…..
Gravity - as distinct from gravitation is a physical force produced and experienced by all material objects that possess both mass-energy and a 3D topology…
As photons [and bosons] do not possess a 3D topology [Z component] to their planar 2d fields of mass-energy momenta they are not affected by gravity fields - they are however subject to forces subjected upon them by external EM fields like those found near planets and stars and in particle accelerators etc…
The 'bending’ of light near to stars etc is a in fact the 'lensing or refraction’ of photons of light due to the EM component of gravitational field…. [GR]aviation = [G]ravity + EM fields near Matter.
As GR and Newton alike do not define or differentiate between 2d mass & 3D Matter in their equations neither can explain these physical properties like Tetryonics can…. yet they play an important role in the mechanics of our Universe on all energy scales.. the use of stress energy tensors [Tab] based on E=mc^2 or the geometrics of Newton [G.(M1.M2)/r^2] is simply insufficient to reveal and explain the mechanics of universal gravitation…
Photons are 'Matterless’ particles - weightless EM field geometries
they are comprised of dual equilateral energy quanta [W bosons]
whose inductive loop properties give rise to inertial mass
their energies measured per unit Time gives rise to mass [m]
and and associated square root linear momentum component [p]
They are also geometrically self-similar to the EM field sthey create
and as a result of their charge geometries are their own anti-particle.
A single photon comprised of 2 Planck quanta has:
1.325886534 Joules of ENERGY
and a mass equivalence of 1.475247727 e-50 kg [E/c^2]
the linear momentum of the same photon would be
4.422681422 e-42 n.s [E/c] or [m*c] kg.m/s
and as the photon passes through differing mediums its linear momentum [p=mv] will change as its velocity of propagation will be affected by the impedance [Z = Eo*Uo] of medium itself.
’mass-less particle’ is a complete misnomer for bosons, photons and EM waves alike as is the question what is the 'weight of a photon’..
A photon is weightless in a Gravity field as it is a planar 2d EM field of mass-energy momentum NOT a material 3D particle topology….. but its path can be refracted by the medium [external EM fields and Matter] through which it passes…
