Inventions Thanksgiving 2019

1.  Improved Oxygen-Saturation/Pulse-Rate finger meter.  Digital read-out makes audible tick accompanying each registered beat above half average strength.  Responding to a button-press shows a plot of last minute of pulse heights against time.  This improvement would allow user to identify arrhythmias.

2.  Electro-mechanical back scratcher that can be guided by remote or wired controller and optionally can automatically cover the back area systematically like iRobot Roomba, but able to return later to user-identified areas needing additional scratching, perhaps identified by a signal input as scratcher leaves each such areas.  This would be a great benefit for people with weak or painful joints from shoulders to fingers inclusively.  Further consideration led me to drop the iRobot idea, but to cotinue the powered scratch idea.  This was submitted for patent in the autumn of 2021:

In the same autumn, I submitted patent applications for Semi-Truck Jackknife Blocker:

and Semi-Truck Anti-Jackknife System

3.  To be continued.

Gravity and Inertia

Aether is the hypothetical medium believed since ancient times to fill space and to conduct actions across space including light transmission and gravitational attraction.  Its existence was assumed by scientists until experiments in 1887 to detect it failed.  Michelson and Morley designed an extremely sensitive device that employed interference between split light beams to detect movement of the earth through the light-bearing medium.  The result was convincingly negative, so scientists abandoned aether-based theories.
Relativity and quantum mechanics developed without assumed aether, and physicists came to eschew the word aether.  Einstein explained gravity as an effect of bending space-time, this resulting in acceleration of matter bodies towards each other.  Beginning with Max Planck, light became viewed as streaming energy bundles (quanta) called photons, not so much as waves propagated in a medium.  A modern version of quantum theory postulates fields whose disturbances might become particles or propagated waves.  Scientists who dismiss aether postulate an electromagnetic field and a gravity field (maybe the Higgs field) and perhaps a field for any remaining force and/or particle.  Honestly, I’m lost in these fields, and I can’t see how their disturbances can be particles.  The waves that I know pass through each other unaffected.  Quantum fields sound to me like aether reincarnate.
I’m inclined to suspect that light is electromagnetic waves in aether.  I can’t find a robust definition of photon intended by all physicists in all applications; so, for all I know, an electromagnetic wave might be a photon or a shower of photons.  I suspect that gravity is an imbalance of electroneutral aether waves (possibly compression waves) resulting in acceleration of mass (=energy) elements of matter.  Alternatively, gravity might be an effect of flowing aether a portion being absorbed by mass elements.
Inertia seems to involve the same elements of matter as does gravity, elements interacting with a space-filling field postulated by Higgs.  Current scholarly thought about the Higgs mechanism evades me, but I suspect that all energy bearing elements of matter interact with some field, which is aether or a component of aether.  I’m just speculating that the old aether idea might anticipate and embrace modern field theory.  It’s hard to tell what scholars mean by their words.
It seems that the force needed to accelerate an object is the force needed to accelerate the aether connected to mass elements in the object.  Considering the density of heavy elements, neutron stars and black holes, the impeding concentration of aether must be enormous, most of it indifferent to matter that we live with and experience.  It’s fun to consider how it is that an object in space accelerated in a given direction seems to continue coasting at that velocity indefinitely, given all the aether everywhere.  Let’s discuss it.  Might aether be almost infinitely fluid and almost infinitely resilient by comparison with familiar matter?  What aether (field) characteristics could account for inertia – the external force needed to accelerate an object and the external force needed to decelerate a coasting object?
The correct theory must account for the unexpectedly high angular velocity of stars near the periphery of galaxies.
