Origin of Mass. Mass and Mass-Energy Equation from Classical-Mechanics Solution
We establish the classical wave equation for a particle formed of a massless
oscillatory elementary charge generally also traveling, and the resulting
electromagnetic waves, of a generally Doppler-effected angular frequency \w,
in the vacuum in three dimensions. We obtain from the solutions the total
energy of the particle wave to be \eng=\hbarc\w, 2\pi \hbarc being a
function expressed in wave-medium parameters and identifiable as the Planck
constant. In respect to the train of the waves as a whole traveling at the
finite velocity of light , \eng=mc^2 represents thereby the translational
kinetic energy of the wavetrain, m=\hbarc\w/c^2 being its inertial mass and
thereby the inertial mass of the particle. Based on the solutions we also write
down a set of semi-empirical equations for the particle's de Broglie wave
parameters. From the standpoint of overall modern experimental indications we
comment on the origin of mass implied by the solution.Comment: 13 pages, no figure. Augmented introductio
Force and Mass Dynamics in Non-Newtonian Suspensions
Above a certain solid fraction, dense granular suspensions in water exhibit
non-Newtonian behavior, including impact-activated solidification. Although it
has been suggested that solidification depends on boundary interactions,
quantitative experiments on the boundary forces have not been reported. Using
high-speed video, tracer particles, and photoelastic boundaries, we determine
the impactor kinematics and the magnitude and timings of impactor-driven events
in the body and at the boundaries of cornstarch suspensions. We observe mass
shocks in the suspension during impact. The shockfront dynamics are strongly
correlated to those of the intruder. However, the total momentum associated
with this shock never approaches the initial impactor momentum. We also observe
a faster second front, associated with the propagation of pressure to the
boundaries of the suspension. The two fronts depend differently on the initial
impactor speed, , and the suspension packing fraction. The speed of the
pressure wave is at least an order of magnitude smaller than (linear)
ultrasound speeds obtained for much higher frequencies, pointing to complex
amplitude and frequency response of cornstarch suspensions to compressive
strains
Internally Electrodynamic Particle Model: Its Experimental Basis and Its Predictions
The internally electrodynamic (IED) particle model was derived based on
overall experimental observations, with the IED process itself being built
directly on three experimental facts, a) electric charges present with all
material particles, b) an accelerated charge generates electromagnetic waves
according to Maxwell's equations and Planck energy equation and c) source
motion produces Doppler effect. A set of well-known basic particle equations
and properties become predictable based on first principles solutions for the
IED process; several key solutions achieved are outlined, including the de
Broglie phase wave, de Broglie relations, Schr\"odinger equation, mass,
Einstein mass-energy relation, Newton's law of gravity, single particle self
interference, and electromagnetic radiation and absorption; these equations and
properties have long been broadly experimentally validated or demonstrated. A
specific solution also predicts the Doebner-Goldin equation which emerges to
represent a form of long-sought quantum wave equation including gravity. A
critical review of the key experiments is given which suggests that the IED
process underlies the basic particle equations and properties not just
sufficiently but also necessarily.Comment: Presentation at the 27th Int Colloq on Group Theo Meth in Phys, 200
