book channel and was shocked to see Arthur Laffer still suggesting that lowering
tax rates could cause higher tax revenues.<span style="mso-spacerun: yes;">
</span>That lie, told to Rumsfeld and Cheney over cocktails during Reagan’s
presidential campaign 5 decades ago, is responsible for our run-away national debt,
our unjust wealth distribution and irrational Republican success (Reagan, Bush
II, Trump) – irrational in that working-class voters would not have voted for
these three phonies had they known that lowering income-tax rates simply transfers
wealth from the national treasury to the richest people on earth, namely bond
holders.<span style="mso-spacerun: yes;"> </span>This has bankrupted the USA, in
that we must borrow from bond holders hence add to our debt to pay interest on existing
debt held by those same bond holders, a vicious cycle.<span style="mso-spacerun: yes;"> </span>That’s Arthur
Laffer’s legacy.<o:p></o:p></span></p>
<p align="left" class="MsoNormal" style="text-align: left; text-indent: 35.3pt;"><span style="font-size: 20pt; line-height: 115%;">The details are as follows.<span style="mso-spacerun: yes;"> </span>From WWII to Reagan’s administration, we had
a top tax bracket at or above 70% and our national debt fell steadily from 90%
of GDP to 32% of GDP.<span style="mso-spacerun: yes;"> </span>We were paying our
WWII debt despite costs of the interstate highway system and two more wars.<o:p></o:p></span></p>
<p align="left" class="MsoNormal" style="text-align: left; text-indent: 35.3pt;"><span style="font-size: 20pt; line-height: 115%;">As soon as Reagan lowered the top tax
bracket to and below 50%, our national debt began climbing above 32% of GDP, passing
100% of GDP in 2010 and reaching 122% of GDP today: a quadrupling of national debt.<span style="mso-spacerun: yes;"> </span>There was a period of diminishing national debt
in the late 90s, quickly stifled by Bush-II tax cuts. <span style="mso-spacerun: yes;"> </span>As expected from the Laffer/Reagan tax changes,
the wealthiest 1% of our citizens went from receiving 8% of national income in 1980 to receiving
18% of national income in 2010.<o:p></o:p></span></p>
<p align="left" class="MsoNormal" style="text-align: left; text-indent: 35.3pt;"><span style="font-size: 20pt; line-height: 115%;">Reasonable people predicted much of
this when the Laffer curve became national doctrine back in 1980.<span style="mso-spacerun: yes;"> To the extent that</span> wealthy bond holders are responsible for
perpetuating Laffer’s lies, then it is abuse of power.</span></p><p align="left" class="MsoNormal" style="text-align: left; text-indent: 35.3pt;"><span style="font-size: 26.6667px;">Instead of starving the poor or increasing the debt limit, it would be better to back off of the latest tax cut slightly.</span></p><p align="left" class="MsoNormal" style="text-align: left; text-indent: 47.0667px;"><span style="font-size: 20pt; line-height: 115%;">For details see:</span></p><p align="left" class="MsoNormal" style="text-align: left; text-indent: 47.0667px;"><span style="font-size: 20pt; line-height: 115%;"><a href="https://ethicsblackhole.blogspot.com/2012/11/us-macroeconomic-history.html">US Macroeconomic History</a></span></p><p align="left" class="MsoNormal" style="text-align: left; text-indent: 47.0667px;"> <span style="font-size: large;">Addendum: The most important consequences of Laffer's "irrational Republican success (Reagan, Bush II, Trump)" is not the national debt, which can still be fixed; it is the growth of right-wing anti-intellectualism, making rational energy policy impossible. Instead of Jimmy Carter, we got Reagan who tore the solar panels off the White House roof. Instead of Al Gore who wanted to combat global warming, we got Bush II who started a criminal war out of spite. Instead of Hillary Clinton, we got ignorant sensationalist Trump. Instead of international family planning we got the gag rule and widespread food insecurity, immeasurable suffering and the population bomb spilling out of the southern continents.</span></p>David Regenhttp://www.blogger.com/profile/09306296757247356920noreply@blogger.com0tag:blogger.com,1999:blog-4403524490230173559.post-36250569475983637412022-12-24T18:04:00.101-08:002024-03-01T06:35:25.973-08:00Semi-truck Anti-jackknife System<p><span style="font-size: large;"><span style="white-space: pre;"> </span>A semi-truck is said to be jackknifing if the angle between its tractor <b>41</b> and its trailer <b>42</b> increases undesirably – the tractor has veered leftward and is drifting rightward (as in Fig B), or it has veered rightward and is drifting leftward. The rig becomes an unsteerable, multimillion-dollar threat to itself and others. Drivers instinctively steer in the direction of drift, which would realign the tractor with its trajectory, if the front wheels could roll freely while other wheels are braked.</span></p><p><span style="font-size: x-large; white-space: pre;"> </span><span style="font-size: large;">We</span><span style="font-size: large;"><span> (</span>David M Regen, Samuel M Regen</span><span style="font-size: x-large;">,</span><span style="font-size: large;"><span> Ingrid L Regen</span><span>) recently patented our </span><b><i>Jackknife-Prevention System</i></b><span>. It is a set of sensors (lateral-acceleration sensor <b>15</b>, steering-direction sensor <b>16</b>) and effectors (front-wheel-brake disablers <b>18</b>,<b>19</b>) which help </span><b>restore alignment</b><span> of a sideward-skidding (drifting) semi-truck tractor <b>41</b> with its trajectory <b>43</b>. The lateral-acceleration sensor could be a mercury-ball tilt sensor, the steering-direction sensor could be a steering-angle sensor with appropriate processor or a three-way switch without a processor, and the brake disablers could be electrically powered three-way solenoid valves or three-way ball-cock valves. In essence the system disables both front brakes of a leftward-drifting tractor when it is steered leftward or of a rightward-drifting tractor when it is steered rightward. This allows the front wheels to advance faster than other wheels, thereby aligning the tractor with its trajectory and making the rig again steerable. These actions should occur only when the key is on and the brakes are applied, so the sensors should receive signal power from the brake-light circuit and should trigger a relay to pass power from the key-on circuit to the effectors.</span></span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span><span>The actions to restore alignment of a sideward-skidding trailer-hauling tractor with its trajectory will also help restore alignment of any sideward-skidding vehicle with its trajactory, thereby reversing spin-out of any vehicle, including a trailerless semi-truck tractor. Semi-truck drivers fear spin-outs as much as jackknifes.</span></span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJZFkwaczzAMO8WyRV0AwohkGx_vhh07TaYKLppsb0iJ2e7aMY9vsLwAhG_4rPuLsygvLsQm4QhikZjlw6WurStqSz6TVighLRvhIz-1fAs_XnKCrHirXS5ajP3mLkO6LAnyLEdxKb9wZ2CF2Y-cF6i0eSIGyj4DUsL242bp0DQtRNC6ZsfZziJesz/s691/UnbrakeSystemFig1bAlt.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="691" data-original-width="534" height="355" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJZFkwaczzAMO8WyRV0AwohkGx_vhh07TaYKLppsb0iJ2e7aMY9vsLwAhG_4rPuLsygvLsQm4QhikZjlw6WurStqSz6TVighLRvhIz-1fAs_XnKCrHirXS5ajP3mLkO6LAnyLEdxKb9wZ2CF2Y-cF6i0eSIGyj4DUsL242bp0DQtRNC6ZsfZziJesz/w275-h355/UnbrakeSystemFig1bAlt.png" width="275" /></a></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: left;"><span style="font-size: large;"><span style="white-space: pre;"> </span>A tractor can become misaligned several ways. For example, the driver might apply brakes when the tractor’s right wheels are on a slippery area (liquid or gravel) or vise versa. The tractor will veer to the side with greater traction. If it veers leftward (as in Fig B), it will drift or skid rightward, and vise versa.<span style="white-space: pre;"> </span></span><span style="font-size: large;">Another jackknife cause is braking while turning -- for example, braking while changing lanes, braking while dodging an obstacle or braking while exiting the highway via an off-ramp. The trailer's inertia pushes the tractor's rear in the direction of the trailer's trajectory <b>43</b>. This push, being off-center with respect to the tractor's footprint, constitutes a spinning force to exaggerate the tractor's yaw. Front-wheel unbraking in response to appropriate steering of a sideward-drifting tractor will restore alignment regardless of cause.</span></div><div class="separator" style="clear: both; text-align: left;"><span style="font-size: large;"><br /></span></div><div class="separator" style="clear: both; text-align: left;"><span style="font-size: large;"><div class="separator" style="clear: both;"><div class="separator" style="clear: both; text-align: left;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVldyBVjQ7GxfdTEaiMZcJ2pmRRtg6yrkuRWwABaWl317U24sBevLguXxyqPZ6tXUhZn9IJ2ttrZDRpcBMHGCS8xWmJE_fFuEV1SWMFXY2kTLnyC4NiedaT6WGJ7x9qKTqZZwmGZU0u-U-akRIGUQSRRaiP0HW5ipMNAHo6dFn2C8HT4OhUBxNtnhg/s972/UnbrakeSystemFig2.png" style="clear: left; display: inline; margin-bottom: 1em; margin-right: 1em; text-align: center;"><img border="0" data-original-height="579" data-original-width="972" height="264" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVldyBVjQ7GxfdTEaiMZcJ2pmRRtg6yrkuRWwABaWl317U24sBevLguXxyqPZ6tXUhZn9IJ2ttrZDRpcBMHGCS8xWmJE_fFuEV1SWMFXY2kTLnyC4NiedaT6WGJ7x9qKTqZZwmGZU0u-U-akRIGUQSRRaiP0HW5ipMNAHo6dFn2C8HT4OhUBxNtnhg/w439-h264/UnbrakeSystemFig2.png" width="439" /></a></div><span style="white-space: pre;"> </span>We contend that our jackknife-prevention system is effective under circumstances where alternative systems might fail.

Both events were led by some of us octogenarian guitar-playing camp alumni.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>We met a few times to prepare for these occasions and to enjoy some country tunes from our youth. One of them sounded pretty good, <a href="https://www.youtube.com/watch?v=2r9ynKRGsC8" target="_blank">Blue eyes crying in the rain</a>. The lead singer in this video was Larry Stumb, who assembled some pickers perhaps a year later to lead music down at the Nashville Rescue Mission for morning devotionals led by one of Larry’s friends. We did that several times over the next year or so. Preparing for those events evolved into a song circle that met every few weeks at the homes of the pickers, early on in Larry Stumb’s back-room den, then in Coach Stewart's sun room and eventually in Bill Brown’s basement den.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>We were all in our eighties and unsteady, so we decided to name ourselves “The Stumblers” – alluding to our infirmities and honoring our founding member, Larry Stumb. Early on, Bill’s energetic young friend and helper Ashlie Jewel joined the group and became the sine-qua-non of the circle, as can be appreciated in the following videos: <a href="https://youtu.be/bUpw-Djfnok">I am weary</a> and <a href="https://youtu.be/fow47Q5riM8">Last Cheater's Waltz</a> .</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>I had to quit a few years ago, having dozed off at a few traffic stops on the way home. Larry Stumb became too crippled to continue and he died about a year ago. He was the consummate people person, interested in and supportive of everyone he knew. His devotion to country music was inspiring; his knowledge of it encyclopedic. This long-lasting song circle, <i>The Stumblers</i>, keeps on regenerating itself owing to Bill Brown's generous hosting and Ashlie's loving direction. It is a worthy tribute to its namesake, our modest and devoted friend, Larry Stumb.</span></p>David Regenhttp://www.blogger.com/profile/09306296757247356920noreply@blogger.com0tag:blogger.com,1999:blog-4403524490230173559.post-12143064263857202462022-04-02T15:42:00.012-07:002022-04-03T16:05:17.235-07:00Ethical international relations<p><span style="font-size: large;"> Sometimes I try to analyze complex systems, to articulate cause-effect laws and to describe mechanisms accounting for them. For example, what is <b><i>evil</i></b>, and what are its causes?<br /></span></p><p><span style="font-size: large;"><br /></span></p><p><span style="font-size: large;"> <span style="white-space: pre;"> </span>Basic drives to preserve and enhance <b><i>the self</i></b> characterize all living things: single cells, plants, animals, families, species, religions, ethnicities, geographic regions. <b><i>Selves</i></b> typically relate to <b><i>nonselves</i></b> (<b><i>others</i></b>) competitively, predatorially and/or selfishly.<span style="white-space: pre;"> </span></span><span style="font-size: large;">Thus, our natural drives often cause suffering. Unnecessary or unjust suffering is <b><i>evil</i></b>.</span></p><p><span style="font-size: large;"><span> </span><span style="white-space: pre;"> </span><span>Generosity toward offspring is common and constitutes preserving and enhancing the self. Truly altruistic relations among non-spousal adults are rare.</span></span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>Typically we, ourselves, lack the empathy to appreciate the evil done to others. We are even thrilled by the sight of competitors, enemies and perpetrators harmed by our agents (military, law enforcers). We even dream of inflicting such harm. Concern for our enemy’s suffering seems unpatriotic. Concern for a perpetrator’s suffering seems misguided, though perfectly consistent with understanding of scientific determinism.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>Sadly, my tribe has made many harmful mistakes over the years. For example, we as White People should have treated non-whites more justly for centuries. </span><span style="font-size: x-large;"> </span><span style="font-size: large;"><span>We as Americans should have behaved </span><span>more rationally</span><span> in Palestine, Iran, Cuba, Venezuela, Viet Nam, Grenada, Afghanistan, Iraq, Egypt, Lybia and Syria. Many of our actions were in response to and for the sake of wealthy insiders. Some were criminal. Many could have been avoided by application of ethical standards, including Just War Principles, UN Charter and Geneva Conventions.</span></span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>Our sanctions of Venezuela are irrational and spiteful. We, the USA, are causing unnecessary and unjustified suffering in Venezuela, and that makes our actions evil. By the way, their economic woes are due to the oil-price drop and amateur leadership, not communism. The Russia embargo might eventually raise oil prices and help Venezuela. It would be in our interest to help them get their oil industry up and running.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>Likewise our sanctions of Cuba for the past two decades are irrational and spiteful. Their attempts at managed economy haven't threatened us or anyone else for several decades. Back in the Bay-of-Pigs and Missile-Crisis days, we had real conflicts, but that might have been avoided had we respected Cuba's sovereignty.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>We should reconstruct our relations with these two struggling neighbors along ethical lines.</span></p>David Regenhttp://www.blogger.com/profile/09306296757247356920noreply@blogger.com0tag:blogger.com,1999:blog-4403524490230173559.post-81489169630790023602022-03-28T15:47:00.024-07:002022-04-03T15:44:36.844-07:00The Ukraine War<p><span style="font-size: large;"><b>Some thoughts about the Ukraine war</b>:</span></p><p><span><span><span style="font-size: x-large;"> </span><span style="font-size: large;"> </span></span><span style="font-size: large;">It seems to me that the Russian convoys could have been stopped just inside the Ukrainian border, had there been a little forethought. </span></span></p><p><span style="font-size: large;"><span> </span>1. Ukraine should have placed tank barriers near the border crossings decades earlier, certainly after the Crimean invasion. Many barriers could have been permanent and others could have been positioned when the threat became imminent, not to obstruct domestic traffic prematurely. </span><span style="font-size: large;">An array of disabled tanks and trucks on and about the border-crossing roads would be a barrier to those lined up to invade.</span></p><p><span style="font-size: large;"><span> </span>2. Ukraine should have built up an arsenal of anti-tank/anti-truck drones, as soon as such weapons became available. All too late, they are using drones effectively to drop explosive darts on the vulnerable tops of tanks. Drones could deliver a wide variety of non-destructive and non-lethal vehicle-</span><span style="font-size: large;"><span>stopping</span><span> and personnel-stopping bomblets.

To be specific, evil taints all Republicans since the party morphed from conservative to deceptive, seditious and racist -- since it ceased respecting truth and loving justice. The gifted people of whom I speak are now endangering democracy and peace. Not one Republican has apologized for the Jan-6 attempt to end America's experiment with democracy. Judging from their media appetites, they are hostile to </span><span style="font-size: large;"><span>evidence and</span><span> </span><span>reason. They'd rather follow a messiah than analyze socio-ethical dynamics. Some fear economic repercussions of intellectual independence. The compassionate people who volunteer to help victims of storms, fires, earthquakes and famines are the same people who now threaten democracy.</span></span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>The places where I felt meaningful and experienced joy during the past quarter century were Woodmont Christian Church and Bellevue Christian Church. There I was inspired to care about and help the disadvantaged, I gladly volunteered time and resources to upkeep of the church buildings, and I was welcome to exercise my love of music, for example: <a href="https://www.youtube.com/watch?v=LulGpZq1HZY">orchestrations</a>, <a href="https://www.youtube.com/watch?v=C-1fu3iKkK4">bands</a>, and <a href="https://www.youtube.com/watch?v=-KjFn7rT_8Q&t=183s">singalongs</a>.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>But now I’m afraid to expose my thoughts in those places for fear of driving congregants away and for fear of demoralizing the old and sick</span><span style="font-size: x-large;"> </span><span style="font-size: large;">who</span><span style="font-size: large;"> deserve to feel worthy as they face their dooms after lives of faith and decency.</span></p>David Regenhttp://www.blogger.com/profile/09306296757247356920noreply@blogger.com0tag:blogger.com,1999:blog-4403524490230173559.post-9897661529020603832021-11-05T18:17:00.007-07:002022-10-10T14:11:48.226-07:00My bluegrass quest<p><span style="font-size: x-large; white-space: pre;"> </span><span style="font-size: large;">Since I was 4 years old, I have dreamed of playing in a band. In high school, I was in a group of square-dance pickers – Bill Brown, Starkey Duncan, Ben Adams, Joe Collier, Fred Beasely, my brother Barney and two others. After highschool, we went our ways and lost track. Twenty years later, Bill Brown assembled a group of friends to play a square a dance at Brentwood Academy, where he was headmaster. At the time, I was trying to learn banjo, which turned out to be the main melodic instrument in his band.</span><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjCjO4J4oBVrTIPgJL8-qHJmnHFr4O_LWlDRZqrnUhTlSNxQgPgVENyQkjFR8Rw81Qzk7QoaKvpKfESUCoOK0w6htaUg4KGLYCaVv_CyDueUyPjYBLcQH4kPjFf16Z2DuRdlj26a6wLfNuW5rZoOFOAPn3GiGJ7eUytxeKLKsrLGHlJutDGGrPBIJNw/s1455/BrentwoodBand.png" style="margin-left: 1em; margin-right: 1em; text-align: center;"><img border="0" data-original-height="776" data-original-width="1455" height="226" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjCjO4J4oBVrTIPgJL8-qHJmnHFr4O_LWlDRZqrnUhTlSNxQgPgVENyQkjFR8Rw81Qzk7QoaKvpKfESUCoOK0w6htaUg4KGLYCaVv_CyDueUyPjYBLcQH4kPjFf16Z2DuRdlj26a6wLfNuW5rZoOFOAPn3GiGJ7eUytxeKLKsrLGHlJutDGGrPBIJNw/w422-h226/BrentwoodBand.png" width="422" /></a></p><p><span style="font-size: large;">The highlight of the evening was Jerry Reed joining in for a couple of songs. That band included Bill, his brother Larry, Allen Wallace and me. Rob, Jonny and Coleman, the singing Harwell boys soon joined, then an extremely talented banjo player, David Hickman, who would be our star. Tom Shriver and Sam Shannon joined soon thereafter. Alex Shipley joined later. In 1976, we were invited to perform a stage show on the War Memorial Plaza for the Bicentennial Arts Celebration. Riding to that gig, Coleman started talking about a sign in the Union Station that read “Outbound Freight”, and suddenly the band had a name.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>The </span><span style="font-size: large;">OBF</span><span style="font-size: large;"> was invited to perform at numerous civic events. They played the same songs at every gathering, so I sought opportunities</span><span style="font-size: large;"> to sit in with groups on stage at various Nashville taverns: Dusty Road, Station Inn (the Red and Birdie era), Golden Nugget, Bluegrass Inn, Kindly Keep it Bluegrass, Trinity Lane x Dickerson Rd. I played with some country pickers in a VFW dance band. One of them died of a gunshot wound received when wooing a married woman. One of them had an interest in Nashville’s dirtiest dive, “The Wigwam”, and he dragged us down there a couple of times after VFW gigs. It was on 3rd Ave next to Cathy’s Massage Parlor on one side and worse on the other. The </span><span style="font-size: large;"><span>300-pound</span><span> proprietor was always in overalls, shirtless and seriously malodorous. He was proud of his ability to draw a pistol out of the cash register if needed. He often slept the night on a pool table in the back room, parked in the middle, so people wouldn’t fall through the 2'x2' hole, covered also by a rug to keep out varmints and cold.</span></span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>The Wigwam people asked me to perform in a special event to be filmed for a documentary. The song was new to me, so I faked my way through it, embarrassingly. I saw and heard the result for the first time several weeks ago. The man smoking and drinking in the foreground was Townes VanZandt: <a href="https://www.youtube.com/watch?v=7M4FYaqmHb8">Heartworn Highways</a>.</span></p>David Regenhttp://www.blogger.com/profile/09306296757247356920noreply@blogger.com0tag:blogger.com,1999:blog-4403524490230173559.post-67499493126554788082021-02-09T09:37:00.011-08:002021-02-10T17:32:49.308-08:00Publications, Membrane transport & metabolism<p>1) Evidence for functionally distinct transporters in basal and insulin-stimulated adipocytes; Biochemistry 28: 6937-6943, 1989; RR Whitesell, DM Regen, NA Abumrad</p><p>2) Activation energy of the slowest step in the glucose carrier cycle: Break at 23oC and correlation with membrane lipid fluidity; Biochemistry 28; 5618-5625, 1989; RR Whitesell, DM Regen, AH Beth, DK Pelletier, NA Abumrad</p><p>3) Mechanism of the acute action of insulin on hepatic gluconeogenesis; Mechanisms of insulin action, Chapter 21, 305-321, Elsevier Science Publishers, Biomedical Div ; ~1986 ; TH Claus, MR El-Maghrabi, DM Regen</p><p>4) Role of hepatic glycolysis and gluconeogenesis in glycogen synthesis; BioEssays 2, 6; 273-276, ~1985; SJ Pilkis, DM Regen, TH Claus, AD Cherrington</p><p>5) Evidence for two catalytic sites on 6-phosphofructo-2-kinase/fructose 2,6-bisphosphatase; J Biological Chemistry 259; 949-958, 1984; SJ Pilkis, DM Regen, HB Stewart, J Pilkis, TM Pate, MR El-Maghrabi</p><p>6) Effects of pH on B-hydroxybutyrate exchange kinetics of rat erythrocytes, Biochemica et Biophysica Acta 601, 500-508, 1980; DM Regen, HL Tarpley</p><p>7) Glucose transport characteristics of quiescent thymocytes; J Biol Chem 253; 7289-7294, 1978; RR Whitesell, DM Regen</p><p>8) Effects of insulin on kinetics of sugar transport in heart muscle; Am J Physiol 234; E70-E78, 1978; JY Cheung, C Conover, DM Regen, CF Whitfield, HE Morgan</p><p>9) Effects of pH on B-hydroxybutyrate transport in rat drythrocytes and thymocytes; Biochemica et Biophysica 508, 539-550, 1978; DM Regen, HL Tarpley</p><p>10) Mitogen-stimulated glucose transport in thymocytes; J Cell Biol 72; 456-469, 1977; RR Whitesell, RA Johnson, HL Tarpley, DM Regen</p><p>11) Anaerobic stimulation of sugar transport in avian erythrocytes; Biochemica et Biophysica Acta 470; 212-229, 1977; JY Cheung, DM Regen, ME Schworer, CF Whitfield, HE Morgan</p><p>12) Dynamic aspects of glucose transport modulations in thymocytes; J Biol Chem 252 #10; 3533-3537, 1977; RR Whitesell, LH Hoffman, DM Regen</p><p>13) B-hydroxybutyrate transport in rat brain: developmental and dietary modulations; Am J Physiol 230 #3; 619-630, 1976; TJ Moore, AP Lione, MC Sugden, DM Regen</p><p>14) Transport of D-allose by isolated fat-cells: An effect of adenosine triphosphate on insulin stimulated transport; J Cell Physiol 89 #4;651-660, 1976; EG Loten, DM Regen, CR Park</p><p>15) Effect of thyroid hormone on cerebral glucose metabolism in the infant rat; Am J Physiol 225; 925-929, 1973; TJ Moore, AP Lione, DM Regen</p><p>16) Anomalous transport kinetics and the glucose carrier hypothesis; Biochem Biophys Acta 339; 218-233, 1974; DM Regen, HL Tarpley</p><p>17) Sugar transport in beef erythrocytes; Biochem Biophys Acta 266; 174-181, 1972; RT Hoos, HL Tarpley, DM Regen</p><p>18) Brain glucose metabolism in the newborn rat; Am J Physiol 221#6;1746-1753, 1971; TJ Moore, AP Lione, DM Regen, HL Tarpley, PL Raines</p><p>19) Brain glucose metabolism in the intact mouse; Am J Physiol 221#6; 1738-1745, 1971; WA Growdon, TS Bratton, MC Houston, HL Tarpley, DM Regen</p><p>20) Effects of simple diets on cholesterol synthesis in rat liver; J Nutrition 101; 437-444, 1971; EB Terrell, DM Regen</p><p>21) Sugar transport across the blood-brain barrier; Am J Physiol 219#5; 1505-1513, 1970; PM Buschiazzo, EB Terrell, DM Regen</p><p>22) Regulatory significance of transfer RNA charging levels1.

He</span><span> was afflicted with mild dyslexia, OCD, ADHD and asperger</span><span>,</span><span> so he did not thrive in grammar school. On two occasions he took remedial reading. But, owing to a strong warning on the first day of high school, he did his math homework daily and eventually completed calculus. He credits his graduate-school mentor, Charles Rollo Park, with teaching him everything useful, including communication. Getting a summer job in Dr Park's research lab after one year of medical school was fortunate in several ways. He found a career path in academia rather than patient care for which he was utterly unfit. One of his lab colleagues happened to know the elegant girl who strolled through the cafeteria during coffee break, enabling him to meet his future wife Lieselotte (Lilo) Wilde. Lilo was an immigrant from Germany, who worked in the hospital records room by day, attended UT by night, and studied art on weekends. She would paint beautiful pictures and scribe beautiful calligraphs and teach these skills professionally. She was a master chef and hosted numerous guests. She </span><span style="color: red;">was/</span><span style="color: red;">hasbeen</span><span> </span><a href="https://www.youtube.com/watch?v=Rvryh4bihro">beautiful and creative</a><span> throughout her </span><span style="color: red;">&&</span><span> years.</span></span></p><p><span style="font-size: medium;"><span><span style="white-space: pre;"> </span>David was curious – later good for his science, earlier bad for his bones and skin. As a kid, he often walked barefoot through the glass-strewn alleys looking in people’s trash pits for mechanical devices, to study, repair or scavenge. Attempting to climb from top of garage door to roof, he fell head first and broke his right elbow in four places. Exploring alternative ways to descend stairs, he broke his left arm in one place. Attempting to dive into shallow water like sailors from a burning ship, he broke his back, wore a torso cast for a month. Attempting to walk on the wall of a school’s incinerator, he fell into the fire, burning the skin off both legs from shoes to shorts. His legs were then covered with mercury ointment and wrapped for a month. Between ages 11 and 25, he suffered constantly painful duodenal ulcers causing chronic insomnia and several nearly lethal hemorrhages and bile-duct obstructions. He designed a blow-torch that almost burned down his house.</span><span> He raised a few chickens and rabbits, which he slaughtered and butchered for food.</span><span> There were punctures, lacerations and sports injuries as well as toxic-metal exposures. Working on a lawnmower a</span><span>t age 84</span><span>, he <a href="https://www.youtube.com/watch?v=RG1M2OatYWw">severed the extensor tendon</a> of his left middle finger, cutting half through the knuckle.</span></span></p><p><span style="font-size: medium;"><span style="white-space: pre;"> </span> He trusted his scientific instincts and spent his last half decade attempting to understand <a href="https://ethicsblackhole.blogspot.com/search?q=gravity">gravity</a> and <a href="https://ethicsblackhole.blogspot.com/2017/08/photon.html">light</a>. He encountered several unsatisfying theories and proposed a few of his own. He also advanced some <a href="https://ethicsblackhole.blogspot.com/2021/02/the-homelessness-problem.html">social/political ideas</a> for discussion. He waited in vain for the contrition owed by <a href="https://ethicsblackhole.blogspot.com/2021/01/january-6-2021.html">MAGA Republicans</a> for Jan 6, 2021 and for supporting misinformation broadcasters. At age 87, he invented two ways to prevent semi-truck jackknifing and submitted a patent application for each -- likewise a battery-powered back scratcher, but not the <a href="https://ethicsblackhole.blogspot.com/search?q=super+impact+wrench">super impact wrench</a>.</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjWP0OaJTqaZnDy6hFvF4pdBsXhpvW7RGQlVjCiK5w9Fl45C2OBt4112pJl2UeHxVStf-mm70Pexd_IDuF9q5dEfFYI3gJNsvW1yZfZ0Bh6UDNEbY99PlO2hoZ9ZEAOBX854INh_mlcxHs/s1920/September+18%252C+2011+-+24+-A.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1080" data-original-width="1920" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjWP0OaJTqaZnDy6hFvF4pdBsXhpvW7RGQlVjCiK5w9Fl45C2OBt4112pJl2UeHxVStf-mm70Pexd_IDuF9q5dEfFYI3gJNsvW1yZfZ0Bh6UDNEbY99PlO2hoZ9ZEAOBX854INh_mlcxHs/s320/September+18%252C+2011+-+24+-A.jpg" width="320" /></a></div><br /><span style="font-size: medium;"><br /></span><p></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiaQuG_NgGvhS5f_ahuQd2CYHh4ZT5SnCJZiDiwJGrZjdFgHbWUyo3i3ZgOtmhSySs6enulyEBL8QFc5fjdagxV-B2tNUUugnZZSaYhyP4Zjq1vq5ImXl6jSsBzPImoOxnI_4MHmuQARiw/s759/PumpkinFestCrop.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="727" data-original-width="759" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiaQuG_NgGvhS5f_ahuQd2CYHh4ZT5SnCJZiDiwJGrZjdFgHbWUyo3i3ZgOtmhSySs6enulyEBL8QFc5fjdagxV-B2tNUUugnZZSaYhyP4Zjq1vq5ImXl6jSsBzPImoOxnI_4MHmuQARiw/s320/PumpkinFestCrop.png" width="320" /></a></div><br /><span style="font-size: medium;"><br /></span><p></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhjAEu3dr7F1_IL7XsTkhrHSmOBoBDdrDuMjfdVV7-ox1WZbriMjdwGUXCeuCHKCa7f_J5oma0Scoarvc2do-eZBqfLHloQlP9bzeFyg2Occ8K2OmDX0O_guj4PVHsE5emMKGR4hES8UZk/s5472/Tumbleweeds2.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="5472" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhjAEu3dr7F1_IL7XsTkhrHSmOBoBDdrDuMjfdVV7-ox1WZbriMjdwGUXCeuCHKCa7f_J5oma0Scoarvc2do-eZBqfLHloQlP9bzeFyg2Occ8K2OmDX0O_guj4PVHsE5emMKGR4hES8UZk/s320/Tumbleweeds2.JPG" width="320" /></a></div><br /><span style="font-size: medium;"><br /></span><p></p><p><span style="font-size: medium;"><br /></span></p>David Regenhttp://www.blogger.com/profile/09306296757247356920noreply@blogger.com0tag:blogger.com,1999:blog-4403524490230173559.post-4940455217195439292021-02-04T03:46:00.023-08:002021-02-15T15:45:26.689-08:00Inner Ear Accelerometers<p><span style="font-size: large;"> <span style="white-space: pre;"> </span>Every modern ship, plane and satellite is equipped with flywheels in gimbals to detect and report rotational acceleration and displacement. Many of them have devices to detect linear acceleration. Our inner ears are equipped with <a href="https://www.ncbi.nlm.nih.gov/books/NBK279394/">vestibular systems</a>, that detect and report both of these accelerations.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>I don’t know how acceleration data from the inner ear are received in the brain, but I speculate that <a href="https://ethicsblackhole.blogspot.com/2021/01/honeycomb-illusion.html">my honeycomb illusion</a> might be involved in the report. I suspect this because: the honeycomb hexagons that I see on every blank surface don't move when I move my gaze but not head, and they don't move when I move my head but not my gaze, and they don't move when I move both. The honeycomb seems to stay where it was before head and/or eye movement -- as if held in place by feedback from my vestibular system.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>My honeycomb illusion might be my personal frame of reference (that goes with me) or my objective frame of reference (through which I go) or both. Such a reference would allow me to keep track of my relations with surroundings quicker than possible through good visual information and despite poor or lacking visual information.</span></p><p><span style="font-size: x-large; white-space: pre;"> </span><span style="font-size: large;">I invite the curious to weigh in on this speculation.</span></p>David Regenhttp://www.blogger.com/profile/09306296757247356920noreply@blogger.com0tag:blogger.com,1999:blog-4403524490230173559.post-88482830572078293112021-02-03T18:43:00.013-08:002021-02-06T16:09:14.208-08:00The homelessness problem<p><span style="font-size: large;"> </span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>Homeless people living rough on city streets and in city parks interfere with intended uses of those spaces by nearby residents, shopkeepers, shoppers, walkers and drivers. This is much worse in mild-climate states, especially those with humane intentions toward the homeless.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>City, county and state governments have a right and a duty to enable normal use of these areas. So far efforts to limit unauthorized camping or squatting have failed.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>Jailing people for drug trafficking, overdosing, petty theft or trespassing doesn’t relieve street abuse significantly. There isn’t enough jail capacity. Likewise for rehab services. Needed is a new way of housing and caring for people unable to compete for normal housing.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>I wonder whether a variety of <b>last-chance resort colonies</b> would be appreciated and effective. Last-chance resorts would be analogous to the hundreds of prisons now located in rural communities where <a href="https://www.prisonpolicy.org/scans/building.html">prison is the main industry</a>.</span></p><p><span style="font-size: x-large; white-space: pre;"> </span><span style="font-size: large;">Some resorts could be placed in existing towns. Others might be placed in abandoned mining towns rebuilt for the purpose. Resorts would be for people who were repeatedly arrested and who failed three attempts at rehabilitation. Last-chance resorts would have to be walled for the community’s safety. But they would be equipped for and devoted to recreation and entertainment.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>Some resorts would be for sober guests, who can’t compete for various reasons. They might accommodate couples or families. Separate resorts would be for substance abusers who would get enough after-dinner drugs of choice for happy evenings. Monthly socials with opposite-gender last-chance resort colonies might be arranged. Guests who choose and succeed with sobriety could move to half-way houses in hopes of advancing to self sufficiency.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span>These ideas are meant to be ethical, in that they should diminish unjust and unnecessary suffering. How might they be made more so?</span></p>David Regenhttp://www.blogger.com/profile/09306296757247356920noreply@blogger.com0tag:blogger.com,1999:blog-4403524490230173559.post-19855119333989069122021-01-18T09:54:00.019-08:002021-02-11T15:20:18.705-08:00Events of January 6, 2021<p><span style="font-family: georgia, serif; font-size: x-large;"><br /></span></p><p><span style="font-family: georgia, serif; font-size: x-large;">Owing to events of Jan 6, ten suspicions are now certainties.</span></p><p><span style="font-family: georgia, serif; font-size: x-large;">1) A sociopathic president endangers democracy.</span></p><p><span style="font-family: georgia, serif; font-size: x-large;">2) White men in bunches are irresponsible.</span></p><p><span style="font-family: georgia, serif; font-size: x-large;">3) Protection of elected leaders is inadequate.</span></p><p><span style="font-family: georgia, serif; font-size: x-large;">4) Loss of white male privilege awakens wrath.</span></p><p><span style="font-family: georgia, serif; font-size: x-large;">5) Republicans don’t respect society's mores.</span></p><p><span style="font-family: georgia, serif; font-size: x-large;">6) Bill Moyers was right, Civilization is but a thin veneer.</span></p><p><span style="font-family: georgia, serif; font-size: x-large;">7) Republican leaders love neither truth nor justice.</span></p><p><span style="font-family: georgia, serif; font-size: x-large;">8) Social media abuse can evoke felony murder.</span></p><p><span style="font-family: georgia, serif; font-size: x-large;">9) Conservative broadcasters need intervening fact checkers.</span></p><p><span style="font-family: georgia, serif; font-size: x-large;">10) Watters', Hannity's and Levin's lies harm.

With patience I can see this illusion despite features in the field. I see it also with eyes closed and in the dark. Borders between hexagonal cells are dark gray and areas within cells are what's really out there.</span></p><p><span style="font-size: large;"><span style="white-space: pre;"> </span><span>My illusion does not seem to be what is described as “</span><a href="https://journals.sagepub.com/doi/full/10.1177/2041669516660727">honeycomb illusion</a><span>” in Googled sites. Is it possible that this easily experienced phenomenon has never been noticed? It should have been described by Aristotle looking at dawn or dusk sky more than two millennia ago. It should be common knowledge and have a name.

We were prepared for neither, so the remedies were inefficient, insufficient and harmful. Too many people were economically crushed by each recession and the national debt increased too much; that is, had we responded rationally, then fewer people would have lost so much and the national treasury would not be so emptied (indebted).</span></p><p><span style="font-size: medium;"><span style="white-space: pre;"> </span>Here are some emergency government actions that should be prearranged and ready for future economic crises – these in addition to standard safety-net responses.</span></p><p><span style="font-size: medium;"><span style="white-space: pre;"> </span>1) Pay a modest need-based wage supplement to all adults, rather than the flat emergency payment. Not enough to de-incentiveize work.</span></p><p><span style="font-size: medium;"><span style="white-space: pre;"> </span>2) Levy a temporary personal-wealth tax, enough to cover much of the extra treasury draw. This recovers some of the dollars transferred from treasury to the rich by Republican tax cuts.</span></p><p><span style="font-size: medium;"><span style="white-space: pre;"> </span>3) Temporarily slow all debt payments and rent payments, so the above modest wage can prevent defaults and bankruptcies. Payments should suffice to preserve essential banking service.</span></p><p><span style="font-size: medium;"><span style="white-space: pre;"> </span>4) Temporarily and reversibly adjust mortgage bases to partially blunt effects of neighborhood-wide property-value snowballs/dominoes. This shares such owner risks between borrower and lender. Far fewer owners would then go under water. I discussed this earlier: https://ethicsblackhole.blogspot.com/2018/10/flexible-mortgage-contracts.html</span></p><p><span style="font-size: large; white-space: pre;"> </span><span style="font-size: medium;">5) Prohibit excessive mortgage-loan riskiness now, eg excessive interest jumps, excessive 2nd mortgages.</span></p><p><span style="font-size: medium;"><span style="white-space: pre;"> </span>6) Frustrate property predators, vultures, speculators, corporations, foreign investors.</span></p><p><span style="font-size: medium;"><span style="white-space: pre;"> </span>How should this emergency-action list be modified and elaborated by astute ethical economists, ones concerned with survival and justice as well as domestic tranquility? There is still the homelessness problem and the trade-balance problem needing such economists, also the overpopulation and environmental problems, also the problem technologists and automation displacing workers.</span></p><span style="font-size: medium;"><span style="white-space: pre;"> I despair seeing that r</span>eason withers as tribalism thrives.</span><div><br /></div>David Regenhttp://www.blogger.com/profile/09306296757247356920noreply@blogger.com0tag:blogger.com,1999:blog-4403524490230173559.post-8759814341848219632020-08-24T17:00:00.065-07:002023-06-02T07:15:28.760-07:00How does gravity happen?<div><span style="font-size: x-large;"><span style="white-space: pre;"> </span>How does gravity happen? How do separated particles or masses accelerate each other selfward? How does momentum get to and/or from particles in this acceleration? I believe that answers to these questions can be found in properties and actions of a <u>medium that fills all space</u>, which was and still should be named <i>aether</i>.</span></div><div><span style="font-size: x-large;"><span style="white-space: pre;"> A</span>fter all of my musings about gravity and after writing this little essay, I've come believe that the truth is to be found in this <a href="https://www.youtube.com/watch?v=A56jc0_gYZw">YouTube talk</a>. </span></div><div><span style="font-size: x-large;"><br /></span></div><div><span style="font-size: x-large;"><b>Gravity mechanisms</b></span></div><div><span style="font-size: x-large;"><span style="white-space: pre;"> </span>1) One view holds that space is filled with (ie aether contains) momentum-bearing corpuscles or wavelets that push matter particles in the direction of their translation or propagation as they are absorbed (possibly diverted) by those matter particles. Owing to this action, each matter particle is surrounded by a spherically divergent field of diminished corpuscle or wavelet traffic in the direction away from itself, hence a field of excess momentum toward itself. All particles in the universe would be accelerated toward that matter particle and analogously toward each other. Gravity is mutual. I spent some time considering the <a href="https://ethicsblackhole.blogspot.com/2020/03/mechanistic-theory-of-gravity.html">implications of this view</a>.</span></div><div><span style="font-size: x-large;"><span style="white-space: pre;"> </span>2) Another view holds that particles consume, destroy or otherwise diminish adjacent escape potential (fugacity), resulting in a spherically divergent fugacity field, a fugacity gradient toward itself. Particles in such a gradient are accelerated toward lower fugacity, ie toward other particles, in a manner analogous to a proton experiencing an emf. Presumably a particle accelerated this way sends momentum-bearing wavelets (rocket-like) in the opposite (rearward, uphill) direction, momentum being a conserved quantity. This picture comes to mind when I attempt to understand General Relativity.</span></div><div><span style="font-size: x-large;"><span style="white-space: pre;"> </span>3) Another view holds that particles consume or destroy adjacent aether, thereby creating spherically divergent fields of selfward aether flow that wash particles toward each other. Here I'm attempting to convey the <a href="https://www.youtube.com/watch?v=96Oc3ymm3m0">mechanism proposed by Distinti</a> and <a href="https://www.youtube.com/watch?v=hFlzQvAyH7g">others</a>.</span></div><div><span style="font-size: x-large;"><span style="white-space: pre;"> </span>The reader is invited to critique, correct, refine and add to these generalizations (address: xmsdavidr@gmail.com).</span></div><div><span style="font-size: x-large;"><br /></span></div><div><span style="font-size: x-large;"><b>Orbit features</b></span></div><div><span style="font-size: x-large;"><span style="white-space: pre;"> </span>General Relativity is a mathematical model that accounts for all observable orbits and all other gravity effects. My wavelet model by itself can’t account for the simplest of orbits, <a href="https://ethicsblackhole.blogspot.com/2020/05/gravity-paradox.html">two equal masses alone</a> in an otherwise massless universe. Not yet.</span></div><div><span style="font-size: x-large;"><span style="white-space: pre;"> </span><span>Perhaps something can be learned from two unequal masses alone in an otherwise massless universe.</span></span></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3JAWYb34gULdWsI4iyEbqUZME69An0NKsAqwovrmxoqHZ2J6xxEfkYS4-QMnaC3NChNrcr3n2mUIrzczVD76oqIt34xOAflazTwukR4ViAXkrl06OcxUxa2GvEO06wXDfNoi-tV4FJDs/s2048/Gravity21.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2048" data-original-width="1583" height="512" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3JAWYb34gULdWsI4iyEbqUZME69An0NKsAqwovrmxoqHZ2J6xxEfkYS4-QMnaC3NChNrcr3n2mUIrzczVD76oqIt34xOAflazTwukR4ViAXkrl06OcxUxa2GvEO06wXDfNoi-tV4FJDs/w396-h512/Gravity21.png" width="396" /></a></div></div><div><span style="font-size: x-large;">Here we see some interesting locations between the masses – 1) the barycenter, <b>c</b> (center of gravity about which objects orbit, where fugacity is lower than elsewhere in the neighborhood) and 2) the fugacity saddle, <b>s</b> (where the two fields balance unstably and a test object would experience no gravity but would experience centrifugal force). There are several other interesting locations in the system called Lagrangian points, where lighter objects can settle stably and co-orbit around the barycenter with the main masses.</span></div><div><span style="font-size: x-large;"><span style="white-space: pre;"> </span>It seems that the masses are accelerated toward and orbit the barycenter as if that were the source of the centripetally accelerating field. It seems not to matter that the field everywhere is the sum of two gravity fields of masses that are moving and changing velocities. The system behaves as if an object’s fugacity field is instantly established and/or eternal, despite the constant centripetal acceleration of the masses toward each other and the barycenter. Perhaps the fields themselves are gravitationally accelerated as are the masses. This raises the question whether a mass’s field plays a role in its responses to other masses, contrary to Newton’s laws. I'm suggesting here that an object's gravity field responds to a neighbor's gravity field like light (as predicted by Einstein and observed by Eddington).</span></div><div><span style="font-size: x-large;"><span style="white-space: pre;"> </span>If you had no problem believing that two masses in an otherwise massless universe could orbit each other, then you tacitly agree that <b><i><span style="color: #ff00fe;">aether is</span></i></b>, that aether sits or sloshes in an inertial frame of space. Without a reference frame there can be no orbit and no centrifugal force to balance the centripetal force of gravity. Moreover, the orbiting bodies must emit LIGO waves, losing kinetic energy (speed) to the aether; and they must gradually approach each other and merge – these <span style="color: #ff00fe;">two masses alone in an otherwise matterless universe</span>.</span></div><div><span style="font-size: x-large;"> Losing kinetic energy to the aether is tantamount to experiencing a <b><span style="color:

Paradox<span style="font-size: large;"> Occasionally I enjoy contemplating a universe with only two bodies -- originally to address the questions of universal coordinates and space-filling aether, later to consider implications of LIGO waves, recently to see whether I would predict perihelion precession -- this time to see whether I can account for stable orbits. As will be seen, I can't.</span><br />
<span style="font-size: large;"> Owing to their gravity fields, the two bodies would either crash together or orbit each other.</span><br />

Fig 1. Model of two equal bodies orbiting each other. The sunbursts at top and bottom of the orbit circle show where the bodies are now. The small circles at upper-left and lower-right of the orbit circle show where the bodies were earlier when forming the bits of gravity field reaching the bodies now. Arrows toward the small circles and away from starbursts show the direction of the same bits of gravitational field then and now, respectively. Dash lines show the paths of those bits between formation and action. Vertical and horizontal arrows from starbursts show centripetal and tangential components of acceleration, respectively.</div>

<span style="font-size: large;"> As I began to construct this picture, I realized that the gravitational field experienced by each body now is that diverging from the other body earlier when it was behind where it is now. As depicted, the gravitational acceleration is not purely centripetal as needed for orbit stability. It is mostly centripetal, but there is (according to this picture) a small tangential component in the direction of the body's orbital motion -- exaggerated here for illustration.</span><br />
<span style="font-size: large;"> Naively viewed, the picture implies the energetically impossible continual acceleration of each body in its orbital direction -- at no cost to the source of the acceleration. This paradox leads me to suspect that a gravitational field might coast along with the body from which it diverged, thereby accelerating the other body centripetally purely. But would that field coast as if following the circle or the tangent? By what mechanism? Could it be that gravity's acceleratory force propagates in a medium (aether) that is pushed and/or pulled along by massive bodies? Or could it be that the graviton doesn't leave the source until it impacts the target, since time cannot progress in a light-speed agent.</span><br />
<span style="font-size: large;"> Something amazing about the mechanism of gravitational-field propagation might derive from these considerations.</span><br />
<span style="font-size: large;"> My theory of gravity doesn't involve gravitons, , , yet:</span><br />

<span face="" style="background-color: white; font-family: georgia, serif; font-size: medium;"> All neighborhoods gave their sons to the war, sons who volunteered or responded proudly. ‘War rich’ was a pejorative.

<span face="" style="background-color: white; font-family: georgia, serif; font-size: medium;"> With that life experience, I don’t know why Mr Bielawski doesn’t find draft-dodging Trump revolting. How can he forgive Trump’s daily lies, his ignorance, lack of curiosity and his pretense, his long history of using lawyers to cheat contractors and investors? How can he admire someone whose businesses have failed so unfailingly, someone utterly lacking modesty, generosity and empathy, someone who disrespects his spouses and brags about abusing defenseless girls?</span><br />
<span face="" style="background-color: white; font-family: georgia, serif; font-size: medium;"> Those things “this president has done for this country” could have been done better by a president capable of respecting others, one surrounded by experts rather than toadies, one who considers unintended consequences before acting, one who loves truth and justice, one who doesn’t embarrass me every day.</span><br />

<span style="font-size: large;"><br /></span>
<span style="font-size: large;"> 1) The wavelet theory is a version of the gravity theory advanced by Newton's contemporaries,</span><span style="font-size: large;"><span style="font-size: medium;"> </span><a href="https://en.wikipedia.org/wiki/Le_Sage%27s_theory_of_gravitation"> LaSage's Theory of gravitation</a><span style="font-size: medium;">. </span></span><span style="font-size: large;"> </span><span style="font-size: large;">In essence, I postulate </span><span style="font-size: large;">"wavelets" (randomly propagated momentum-bearing light-speed disturbances of space) in place of their</span><span style="font-size: large;"> </span><span style="font-size: large;">"ultra-mundane corpuscles" (momentum-bearing particles darting randomly throughout space faster than light). </span><span style="font-size: large;">I will postulate sources, properties and actions of wavelets that can account for gravity. The analysis leads to the view that the <b>G of Newton's law is not a constant but a location-dependent coefficient,</b> highest in matterless outer space, very high at the edge of a galaxy, lower in mid-galaxy space where we live, lowest in the middle of mid-galaxy stars and black holes -- this because gravitational energy is absorbed as it accelerates matter.</span><br />
<span style="font-size: large;"> My speculation was encouraged when<span style="font-size: large;"> <a href="https://www.youtube.com/watch?v=MvKIVpSpWUA">Saul Perlmutter</a></span><span style="font-size: large;"> </span>, <a href="https://www.youtube.com/watch?v=KnHvLrRKz-k">Adam Riess</a> and <span style="font-size: medium;"> </span><span style="font-family: inherit;"><a href="https://www.youtube.com/watch?v=dQf82LOOm-4">Brian Schmidt</a> </span> received the nobel prize and confidently postulated <b><i>dark energy, a repulsive force emerging in space and accelerating expansion of the universe</i></b>. It occurred to me that <b><i>dark energy could cause other mass-dependent actions at distance -- including</i></b></span><b><i><span style="font-size: large;">: 1) classical gravity; and 2) </span><span style="font-size: large;">the additional centripetal force holding too-fast-orbiting peripheral stars in galaxies, attributed to dark matter.</span></i></b><br />
<span style="font-size: large;"> </span><span style="font-size: large;"> The appendix presents several <b><i>testable predictions</i></b> with which the wavelet theory can be validated or not.</span><br />
<span style="font-size: large;"> 2) In this theory, the agent of gravity is the “wavelet”, a quantum deformation </span><span style="font-size: large;">of space propagated through space at light speed. Wavelets begin spontaneously and randomly in all volumes of space, probably in pairs departing with their momenta in random opposite directions. Thus every volume of space is replete with wavelets from elsewhere propagated through it in all directions, together with a few locally produced wavelets. Quantum fluctuations might be the source of wavelets or might be said wavelets. Wavelets pass through each other without affecting each other.</span><br />
<span style="font-size: large;"> 3) A wavelet carries a quantum of momentum. The relevant deformation in the wavelet is longitudinal compression. Space elements step forward between receiving the pulse from behind and passing the pulse forward, analogous to air molecules during vocal-sound or trumpet-sound propagation (not diaphragm sound). Hence, the medium (aether) drifts bitwise in the dominant direction of wavelet propagation, ie toward masses. This might be germane to gravitational lensing or frame dragging.</span><br />
<span style="font-size: large;"> 4) Matter bodies (stars, planets, moons, people) are penetrated</span><span style="font-size: large;"> </span><span style="font-size: large;">by wavelets</span><span style="font-size: large;"> at great frequency on all surfaces from all directions, a fraction of them hitting mass elements in the bodies, most of them leaving the other side unscathed like neutrinos (Fig 1). If a wavelet hits a mass element, it gives its momentum to the mass element, accelerating it in the direction of that wavelet's propagation. The wavelet is therewith absorbed by the mass element. The mass element then coasts in that direction and shares its momentum with associated matter. Matter is thereby accelerated in the direction of most wavelets hitting it and/or passing through it. Galaxies differ from unitary bodies mainly in absorbing a much larger fraction of wavelets on a diameter path from near rim to far rim, owing to the billions of stars etc on the path (Fig 1).</span><br />
<span style="font-size: large;"> 5) Wavelets are produced spontaneously in all space. In outer space, far from galaxies and galaxy clusters, they are rarely absorbed, so wavelets in any direction are balanced by wavelets (more correctly wavelet resultants) in the opposite direction. A lone particle of matter (p1) in that environment would be accelerated by wavelets at random times in random directions, like Brownian motion. <b><i>Owing to wavelet absorption by p1, there is a deficit of wavelets in all directions away from p1</i></b></span><b><i><span style="font-size: large;">, hence an excess of wavelets toward p1 from all directions</span><span style="font-size: large;">.</span></i></b><span style="font-size: large;"> That spherically diverging wavelet imbalance surrounding p1 would accelerate all other particles in the universe (eg p2) toward p1, and similar wavelet imbalance diverging around p2 would accelerate all other particles in the universe, including p1, towards p2. </span><b><i><span style="font-size: large;">That wavelet imbalance and resulting acceleratory potential would decline with distance from a particle according to the inverse square rule, it being a spherically divergent field.</span></i></b><br />

<div class="separator" style="clear: both; text-align: left;">
<span style="font-size: small; white-space: pre;"> </span><span style="font-size: small;">Fig 0 illustrates spherically divergent wavelet paths through a small or distant object. The shortfall of outgoing wavelets and consequent imbalance are exaggerated to make them obvious; but large imbalances might be typical of a black hole or neutron star or galaxy.</span></div>
<span style="font-size: large;"><br /></span>
<span style="font-size: large;"> 6) To emphasize: A wavelet that accelerates a particle is stopped by the particle and doesn’t continue to the other side. The particle casts a spherically divergent shadow of wavelet-traffic shortage away from itself, hence a </span><b><i><span style="font-size: large;">spherically divergent</span><span style="font-size: large;"> field of excess wavelet traffic towards itself distributed like gravitational potential in </span></i></b><span style="font-size: large;"><b><i>Newton’s Law of Gravity</i></b>. The wavelet imbalance accelerates all other matter in the universe toward that particle. The wavelet deficit is a tiny fraction of wavelet traffic at that location.</span><br />
<span style="font-size: large;"> 7) If the universe had only one matter body, eg a star, it would be surrounded by a spherically diverging shadow of departing-wavelet shortfall, ie arriving-wavelet excess, this imbalance being the body's gravity field. The shortfall or imbalance is a modest fraction of wavelet traffic into the star (unlike Fig 0). Add to this universe a second matter body, eg a planet. Each body would be surrounded by a spherically divergent shadow of excess wavelets towards itself. <b><i>Each body is accelereted toward the other body by the other body's wavelet imbalance.</i></b> They will crash together unless they have momentum transverse to the line between, ie unless they orbit each other providing balancing centrifugal force. [It’s fun to contemplate two matter bodies alone in the universe, orbiting each other, providing centrifugal forces balancing gravity. Wouldn’t they send LIGO waves to the rest of the universe at the cost of their orbital momentum -- then collide or absorb each other when orbital momentum is insufficient. How could this happen without a space-filling aether or universal coordinates for them to move with respect to – contrary to the conclusion of Michelson and Morley upon which modern cosmology is founded?]</span><br />
<span style="font-size: large;"> 8) Owing to wavelet absorption by a body's mass elements, the concentration of wavelets in a given direction declines “exponentially” along the path through a matter body in that direction (Fig 1). Since that applies to all directions, the concentration of wavelets per se declines between points outside the body and the center of a body (Fig 3). Particles nearer the body's surface encounter more wavelets and so contribute more to the body's gravity field than do more central particles. This corollary seems contrary to Newton’s thinking. In stars and smaller bodies this inhomogeneaity may be inconsequential.</span><br />
<span style="font-size: large;"> 9) Accordingly, Newton’s gravitational constant, G, declines with depth into a star (Fig 3). The same applies to a galaxy with its trillions of wavelet-absorbing stars, planets and moons, its black hole and its massive dust and gas clouds. G should be significantly greater at the galaxy’s rim than near the galaxy’s middle where we experience it and measure it. This would account for the ability of stars near the galaxy’s rim to stay with the galaxy despite reaching expected escape velocities according to our local G. Thus, the behavior attributed to <i><b>dark matter</b></i> is due to the gradient of wavelet concentration (hence G) between outer space and inner galaxy.</span><br />
<span style="font-size: large;"> As an aside, this thinking suggests that <b><i>a galaxy's gravitational field might be oblate-spheroidally divergent, the details and implicatioins of which I've yet to ponder</i></b>.</span><br />
<span style="font-size: large;"> 10) The wavelet hypothesis described herein seemed supported by the discovery that <b><i>expansion of the universe is accelerating</i></b> and by the postulate that this is due to a <b><i>repulsive force accelerating galaxies away from each other</i></b>. That force was named <b><i>dark energy</i></b> and was said to emerge spontaneously in space, maintaining constant concentration between galaxy clusters as they separate from each other. I began to suspect that dark energy might be quantum fluctuations producing momentum-bearing wavelets that carry out the accelerations -- including those of gravity. It seemed that <b><i>being pushed away from emptier space was the same as being pushed toward other matter and being pushed toward other matter was the same as being attracted to that other matter</i></b>.</span><br />
<span style="font-size: large;"> However, it is not so obvious that this thinking explains the accelerated expansion of the universe that set me on this quest. To explain accelerating expansion of the universe with this theory, one needs to suppose that there is a void outside the observable universe or matter outside of the observable universe to which the universe’s wavelets can go but from which wavelets aren’t coming into the observable universe. That would result in a wavelet imbalance accelerating matter away from the universe's center and toward whatever is outside the observable universe.</span><br />
<span style="font-size: large;"> 11) It is worth noticing that each wavelet leaves a trail of wavelet-size aether advancements in its wake, so a wavelet </span><span style="font-size: large;">imbalance moves aether, bit by bit, toward massive bodies. This might account for gravitational lensing, the bending of light towards mass. If so, space isn’t bent around massive bodies, it (aether) drifts towards massive bodies carrying light with it.</span><br />
<span style="font-size: large;"> 12) The wavelet theory of gravity implies a mind-boggling, hard-to-swallow corollary: the intensity of gravitational force in a neutron star or black hole is within us and all around us, unnoticed because it is mostly randomly directed, hence mostly balanced.</span><br />
<span style="font-size: large;"> 13) I hope to reconcile the wavelet theory of gravity with the Higgs mechanism when I can understand the latter. Likewise for relativity.</span><br />

<b>GRAVITY THEORY ILLUSTRATED</b><br />
<br />
<span style="white-space: pre;"> </span>According to the wavelet theory:<br />
<br />
<span style="white-space: pre;"> </span>Momentum-bearing wavelets propagated in all random directions permeate all space, including that in all matter. In passing through a matter body some wavelets are absorbed in giving their momentum to the mass elements encountered in the matter. This results in less wavelets leaving the matter body, hence an excess of wavelets toward the matter body -- a net acceleratory potential pushing all matter toward the body. That pushing potential is gravity. The distribution of that external centripetal force able to push matter toward the body is the body's gravity field. It extends to the edge of the universe, diminishing as 1/r^2.<br />
<br />
<span style="white-space: pre;"> Figs 1 - 3</span> illustrate the <b><i>intensity of wavelets between opposite edges of a matter body (star, planet, moon) or of a collection of matter bodies and black holes (galaxy)</i></b>. An intensity or density or concentration of 1.0 is that of distant space far from any galaxies, so the charts show intensity or density or concentration of wavelets <b><i>relative to that in the universe's most matterless space</i></b>.<br />

<span style="white-space: pre;"> </span>Fig 1 shows the exponential decline of rightward wavelets along the path from left edge to right edge of a matter body and the exponential decline of leftward wavelets from right edge to left edge, with six different absorption fractions: 5%, 20%, 50%, 90%, 99% and 99.9%. I suspect that a star absorbs less than 5%, a planet absorbs less than 1%, and a moon absorbs less than 0.1% – in each case probably much less. A galaxy, by contrast, may contain 1 trillion stars, so it might absorb more than 90% of wavelets along a diameter between its rims. The absorption of radially-directed wavelets between opposite rims of the galactic disc would be greater than the absorption of axially-directed wavelets between faces of the galactic disc -- implying interesting shape of a galaxy's gravity field.<br />

<span style="white-space: pre;"> </span>Fig 2 shows the net wavelet traffic between edges of a lonely matter body or of a lonely galaxy. Plotted is the <b><i>difference between opposing wavelet traffic</i></b> and actions, with absorption fractions of 5%, 20%, 50%, 90% and 99%. The net wavelet traffic at an edge is 1.0 minus that which makes it from the other side. If, for example, 20% is absorbed and 80% gets across, the difference at the edge is (1.0 - 0.8) = 0.2, that being a measure of the acceleration forcing the edge matter towards the middle. The acceleration declines towards the middle, where the difference between opposing wavelet actions is zero. That is, <b><i>matter at a body’s center is pressed centripetally by more peripheral matter, but it is not accelerated by local wavelets, which are in balance</i></b><b><i> at that spot</i></b>. I believe I'm saying that <span style="color: red;">this theory has <b><i>no singularities</i></b></span>. Likewise, a body in a galaxy’s center of gravity is not accelerated centripetally. Interestingly, bodies at the galaxy’s rim are most strongly accelerated centripetally, that possibly being the extra force <b><i>preventing stars near the rim from escaping despite angular velocities greater than presumed escape velocity</i></b> – this being the effect historically attributed to <b><i><span style="color: red;">dark matter</span></i></b>. The straight-line declines of acceleration vs position at absorptions less than 50%, are like those of Newton's law. The bent-line declines at 90% and 99% predicting extra centripital force at galaxy's rim are peculiar to the wavelet theory.<br />

<span style="white-space: pre;"> </span>Fig. 3 shows the wavelet density at positions between edges of a body or galaxy. It’s just the <b><i>average of rightward wavelet traffic and leftward wavelet traffic along a diameter</i></b>. At the edge, a 50% absorption results in a density of (1.0 + 0.5)/2 = 0.75. The higher absorptions (>90%) are associated with a significant dip in the profile, there being significantly more wavelet traffic near the edge than near the middle. This distribution should result in <b><i>stronger gravity fields around stars near a galaxy’s edge than around similar stars near the galaxy’s middle</i></b>. Planets should orbit their stars faster near the galaxy’s edge than near the galaxy’s middle. That might be a <span style="color: red;">distinguishing feature of the wavelet theory of gravity</span>.<br />

<span style="white-space: pre;"> </span>Fig. 4 shows the dependence of gravity on mass. The dependent variable is gravitational attraction relative to an hypothetical maximum, that maximum being that which would occur if a matter body absorbed all of the wavelets coming to it. The independent variable is actual mass relative to the mass that would absorb all wavelets, were the beginning proportionality to continue like the dashed line. I speculate that <b><i>stars, planets and moons</i></b> absorb less than 5%, and so would be on that part of the relation at the lower-left corner, which is essentially rectilinear and <b><i><span style="color: red;">proportional as Newton supposed</span></i></b>. Galaxies, with their trillion stars, planets and moons, plus dust, gas and black holes, might absorb more than 90%, so more mass <b><i><span style="color: red;">would not</span></i></b> increase their rim-to-center acceleration proportionally. Sensitivity is fractional change in a dependent variable per fractional change in an independent variable. <b><i><span style="color: red;">Sensitivity of attration to mass in stars, planets and moons is postulated here to be about 1.0</span></i></b>. <b><i><span style="color: red;">Sensitivity of centripetal attraction to mass in a galaxy might be about 0.1</span></i></b>.<br />

As seen, this project consumed the last of the Dietzgen Graph Paper that I kept since retiring 25 years ago.<br />
<br />
<b>Appendix, Experimental expectations:</b><br />
The wavelet theory of gravity predicts several experimental results which, if observed, might validate the theory. At least some of them might reveal limits to Newton's law and/or Relativity.<br />
<br />
1. a) If one gradually lowers a <a href="https://physicstoday.scitation.org/doi/10.1063/PT.3.2447">G-measuring device</a> (sealed in a vacuum bulb and protected from temperature, vibrations, electromagnetic fields and shock) into the <a href="https://wonderfulengineering.com/us-and-russia-raced-to-dig-the-deepest-hole-on-earth-in-1961-this-is-the-story/">12 km hole dug by Russia in a competion with the USA</a> , it will show G declining slightly with depth toward the earth's center according to Fig 3.<br />
1. b) If one gradually lowers that G-measuring device into the deepest part of the ocean, it will show G declining slightly with depth toward the earth's center according to Fig 3, hopefully detectably.<br />
1. c) If one lofts the G-measuring device into space and probes areas nearer the sun and throughout a trip toward outer solar-system limits, it will show G increasing with distance from the sun and other massive bodies, implied in Fig 3. This finding would strongly support the wavelet theory of gravity.<br />
1. d) If one could send that device further toward space outside the milkyway, it will show G increasing with progress into more empty space as in Fig 3.<br />
<br />
2. a) If one estimates G from planet-orbiting velocities near our galaxy's middle and near its rim, the G will be much greater near the rim than near the middle, this owing to less wavelet traffic near the middle, as in Fig 3.<br />
2. b) The same would be expected with axial distance from our galaxy's central plane, as in Fig 3.<br />
<br />
3. If one calculates G from velocities of stars orbiting a galaxy, that G will be maximal near the galaxy's rim and minimal near the galaxy's middle, as in Fig 3. This is well established and evoked the postulate of <a href="https://en.wikipedia.org/wiki/Dark_matter">dark matter</a>.<br />
<br />
4. If it were possible to estimate relative galaxy masses by visual means and to estimate relative galaxy field strengths from effects on neighboring galaxys' trajectories, it might be found that gravitational field strength increases less than proportional to mass, as in Fig 4.<br />
<br /><span style="font-size: medium;"><b>Discussion:</b> </span><div><span style="font-size: medium;"><span> The Michelson/Morely experiments not withstanding, I believe that light and gravity are propagated in aether, and that aether provides a frame in which and relative to which matter and energy move. Accordingly, the orbiting bodies producing the LIGO waves would have sent the waves, lost speed and merged even if they were the only masses</span><span> in the universe. Newton would agree, having contemplated centrifugal force in a lonely system.</span></span></div><div><div><font size="4"> Most physicists would reject the wavelet theory because it predicts that moving bodies would be slowed by headwind, the frequency and momentum of wavelet interactions encountered from the front being greater than those catching up from behind -- apparently defying Newton's first law of motion. But: 1) The headwind would be minuscule in bodies moving slowly relative to the wavelets (and light); 2) Gravity wavelets might be faster than photons, in which case the headwind would be minuscule even if bodies were moving near light speed; 3) Newton's first law is untested axiom (common-sense assumption); moving bodies must experience headwind. Specifically, all moving bodies must produce LIGO waves as they are deflected by gravity from all other bodies in the universe, the energy of those waves being at the expense of the body's velocity.</font></div><div><font size="4"> A matter body always has its gravity field, as it is an assembly of particles having gravity fields since inflation. What departs from a body with the speed of gravity is a wave of acceleration, and this is subdued since it involves momentum-</font><span style="font-size: medium;"><span>conserving</span><span> </span><span>interactions</span><span>. Thus, two bodies passing in space or orbiting each other might interact as if gravity action is infinitely quick.</span></span></div><div><span style="font-size: medium;"> I don't know why General Relativity predicts planetary motions better than do Newton's laws. The geodesic talk sounds spooky and not explanatory. Gravitational-potential gradients and accelertions are probably more germane. In other words, I believe that matter bodies in space are steered by axial and transverse accelerations rather than geodesic grooves.</span></div><div><span style="font-size: medium;"> I don't have a clear notion of the potential referred to above. I suppose it acts on mass elements like heat acts on gas molecules. Perhaps it should be called <b><i>fugacity potential</i></b>. Perhaps my wavelets bear escaping energy rather than momentum.</span></div><div><span style="font-size: medium;"> It is fun to contemplate how two lonely bodies passing each other in opposite directions would perceive each others locations and fields and find themselves in mutual orbit. And that's what I'll continue doing.</span></div></div>David Regenhttp://www.blogger.com/profile/09306296757247356920noreply@blogger.com0
