Challenge for Steve Mould

Steve,
  *  Here is a challenge for you that might have profound scientific interest.
  *  Make a hollow uniformly thick sphere of flexible and resilient material, possibly rubber or plastic, this coated or impregnated with a material that changes color with stretch.  It should have much more inertia than adjacent air so waves would propagate tangentially rather than radially.
  *  With that you should be able to visualize nodes and antinodes of spherical standing waves as you oscillate a small area with focussed sound waves of various pitches.
  *  The dynamics of your sphere should be those of a spherical bell.  You might be the first to observe such dynamics, possibly amazing shapes of overtones.
  *  It seems interesting to speculate whether energies of any electron in any atom might be overtones in spherical electron clouds.
  *  Let me know your thoughts on the spherical bell, if any.

Function of radio-transmitter antenna
The goal is to test the hypothesis that a radio wave is not a unitary electromagnetic wave but instead is a shower of modest-length photons radiating from emf waves (front and back of voltage wave) as they propagate between ends of the antenna.
Studies on loop conductor
 * Using two(or more)-channel oscilloscope with signal generator and nanosecond time resolution, determine time for voltage pulse (leading edge of square wave) to reach points at various distances from positive input.  This can be done with test probes clamped to well separated uninsulated points on a loop conductor (wire forming a complete circuit from source to ground).
 * If oscilloscope cannot resolve this time difference, use longer wire between test probes.
 * If oscilloscope still can’t resolve this time, wind the wire as a spiral coil on a wooden dowel to increase inductance.  Increase number of coil loops to slow voltage pulse enough for time-course resolution.
 * If oscilloscope still can’t resolve this time, replace dowel with steel rod, perhaps a coat-hanger.
 * Using a sufficiently slow conductor, straighten two well separated 4-inch segments.  These will be test segments.
 * To each oscilloscope-channel’s probes, connect a wire loop with a 4-inch straight mid segment, each straight segment being a radiation probe.
 * Place radiation probes close to and parallel to test segments and tune channels to optimize screen display of signals.

 * Record probe signal intensities and emf directions with various probe locations, probe orientations, and objects (including polarizing filters) between test segments and probes.

 * Record probe signal shape with longer and longer voltage square-waves, noting signal decline during sustained voltage.

 * Repeat key measurements with entire loop-conductor shielded by cardboard layered with hardware cloth or aluminum screen (to block unintentional signals) with windows above test segments for intentional signal transfer.  Might be little different.
 * These studies should demonstrate that a voltage change moves as wave front from a source to the conductor's far end, that radiation occurs from any segment only as the voltage front and rear pass, that the radiation is polarized and bears information as to direction and valence of the passing voltage-change wave.
Studies on open circuit ie broken conductor
 * Cut the loop conductor at the midpoint and lay out the halves at some distance from each other.  Repeat key measurements.

Wave reflections of opposite emf valence may be observed.  Wave reflection is a feature of transmitter antennas.  By adjusting frequency, it may be possible to achieve a standing wave, best demonstrated with four evenly spaced radiation probes.
Studies on dipole transmitter antenna
 * Form the two conductor segments into a dipole antenna: conductors adjacent over the first few inches near to signal generator, then turning 90 degrees in opposite directions.  Repeat key measurements.

Wires in dipole-antenna configuration should behave the same as the wires layed out randomly, as regards what happens at various locations and times.
Characterize determinants of transmission efficiency
 * Look at signal picked up by a receiver antenna at various distances and orientations and with various objects in the way.
 * Adjust generator wave form and frequency to establish a standing wave.  Observe strength of signal in receiver antenna as standing wave is achieved.

Mapping wave source vs time

 * Shield transmitter antenna to allow radiation only from selected segments, to characterize sources of radiation at various moments after pulse initiation.  One should see that the signal leaves the transmitter antenna when and where the voltage-change wave is passing.  Parts of the transmitter antenna where and when the voltage-change front is not passing do not participate in radiation to the receiver antenna.  This will require careful time accounting.

Possible findings
 * The above studies might disclose interesting features of electromagnetic radiation and magnetism.
 * It may be possible to demonstrate that the significant radio signal is from the emf pulse during its propagation, not from voltage oscillations, this contary to numerous accounts of transmitter-antenna function.
 * One might get evidence that the significant radiation is of modest wave length (eg infra-red) not the length of radio waves, ie a radio wave is not a photon or unitary electromagnetic wave; it is a shower of modest-length photons (possibly IR) alternating in abundance and spin orientation during each cycle, contrary to some definitions of electromagnetic spectrum and photons.
 * Finally, explanations and accounts of magnetic force are mind-boggling.  Antenna radiation is kin to or the same as or easily confused with establishing and collapsing magnetic fields.  Observing these phenomena and contemplating them might evoke a valuable new insight into the nature of magnetism and radiation.

Country Pathos , Country Soul

Country parables         David M Regen © 1995

Old-time country music, it stirs my heart and soul
It draws me in its circle, my name is on its roll
Its prophets are compelling, its parables profound
So won't you come and join me, in this church of rustic sound

Luke the drifter talked to us, of things we need to know
Think my friend consider well, before a stone you throw
Watch your tongue lift up your thoughts, and gossip don't repeat
For you may be indebted to, the bad girl down the street

Acuff told a story, of one who had succumbed
Life for her was bitter, and from the bridge she jumped
They pulled her from the river, but no one knew her name
This woman had no loved ones, her body was unclaimed

I won't forget Red Foley, my heart-strings he did tug
He told us of the love that is, between a boy and dog
Shep pulled him from the swimming hole, where he had nearly drowned
When Shep was old it broke his heart, to put his dear friend down

These words of Eddie Arnold, I heard them long ago
Do not neglect your mother, the one who loves you so
She nurtured you and guided you, so do not leave her there
All alone an angel in an, old rocking chair

And give my love to Dolly, the brightest of the lot
Her mother made a coat of rags, when she was just a tot
The children all made fun of her, they did not understand
That love went into every stitch, by her dear mother's hand

Yes country can enlighten, wake up your sleeping soul
Turn you from your selfish ways, make kindness  your goal
This world would be a better place, a kinder place I know
With more old-time country music, on the radio

Two tools that ought to be

This week I worked most of three days trying to remove air-conditioner components from my 1996 Mercury Villager minivan -- and wishing for two tools that might be handy in a car repair shop.

  1)  Fixed wrench lever.   To turn a stuck nut or bolt crowded by neighboring structures.  The tool would hold a small eye wrench or C wrench firmly at any desired angle and provide mechanical advantage.

  2)  Shear on a stick.  To cut hoses crowded by neighboring structures.  This would have a hook and blade like a rose clipper at the end of a shaft, the blade forced into the hook by sliding motion rather than scissor motion.  The forcing of blade into hook would come from repeated gripping of a handle at the opposite end.  

Too many cosmic forces

Here's some idle speculation.
* When I was young, the only known cosmic force was gravity.  It attracted matter to matter; and I speculated that it would eventually attract all matter in the universe to a spot in the middle.
* In recent decades, galaxies were found to be distributed quite unevenly in the universe, tending to form a 3-D web or network of galaxy-rich strings with large voids between.  The distribution of galaxies is like the trabeculae of a sponge.  The scaffolding for this galaxy distribution does not emit, absorb or reflect light so it is called dark matter, but it does bend light by gravitational lensing.
* Not long ago, astrophysicist Saul Perlmutter compared supernova brightness (inverse distance) with supernova red shift (departure speed) and concluded that the universe is expanding at an accelerating rate (by a logic that I have failed to follow).  Dark energy was postulated as the force accelerating galaxies apart.  It is said to arise from empty space and to become an ever growing fraction of cosmological force as space between galaxies increases.
  *  Dark energy is said to constitute 70% of the mass of the universe, dark matter is said to be 25% of the mass of the universe, and regular old visible matter is said to be only 5% of the mass of the universe.  That’s three kinds of mass and three kinds of mass-dependent force.
* Could it be that the observable universe is surrounded by a dense shell of matter and energy that departed first in the big bang and is attracting distant parts of the observable universe radially by ordinary gravity, thereby accounting for the relation between distance and rate of departure?   If so, dark energy needn’t be postulated.
* On the other hand, could it be that classic gravity is an illusion, that dark energy does it all?  Could dark energy account for all mass-dependent forces by exerting an isotropic repulsion everywhere from beyond and within the observable universe?  Could accelerations attributed to classical gravity result from shading of this repulsion by masses in the paths?
  *  This last speculation may be compatible with others.

In fact, it is a very old idea  from about 1700.

Firearms

  *  About 1 in 10 adult Americans have psychiatric disorders involving delusions, obsessions, depressions, fears, anxieties, etc.  Many more harbor irrational beliefs about racial, national, political and religious groups and about cause-effect relations.  Many enjoy cruelty.
  *  The vast majority of Americans can get their hands on firearms within a few days of trying.  Thus, the probability of a massacre in any month is substantial.
  *  In light of these facts, our society would seem justified in outlawing large clips and magazines, which greatly advantage anyone with an appetite for massacre – regardless of the NRA’s interpretation of the second amendment.
  *  What are the contrary arguments?

Ellipsoid Wall Thickness

Here's the front of our 2010-Family-Reunion T-Shirt.

It's the last thing I did before retiring about 1995.
Because of it, my 86-year-old wife gets lots of attention at the grocery store.
