The Bidens and the Bible; (CNN) The new twist in Hunter Biden’s case is a huge political headache for his father

(CNN) The new twist in Hunter Biden’s case is a huge political headache for his father. Quoting,

But top GOP lawmakers immediately launched a flurry of attacks on Weiss, despite the fact that he was first appointed under Trump, claiming that far from insulating the case from political influence, his appointment as a special counsel was an attempt at a cover up. The GOP has turned against Weiss because he has not substantiated their evidence-free claims that Joe Biden conspired with his son to enrich their family while he was vice president and they also claim that the plea deal originally offered to Hunter Biden was a “sweetheart” agreement.

I’m not personally a believer. Perhaps Republican campaign strategists are, or claim to be. Quoting from Ezekiel 18:19-20-21-23 The Message (MSG),

“Do you need to ask, ‘So why does the child not share the guilt of the parent?’ “Isn’t it plain? It’s because the child did what is fair and right. Since the child was careful to do what is lawful and right, the child will live truly and well. The soul that sins is the soul that dies. The child does not share the guilt of the parent, nor the parent the guilt of the child. If you live upright and well, you get the credit; if you live a wicked life, you’re guilty as charged. “But a wicked person who turns his back on that life of sin and keeps all my statutes, living a just and righteous life, he’ll live, really live. He won’t die. I won’t keep a list of all the things he did wrong. He will live. Do you think I take any pleasure in the death of wicked men and women? Isn’t it my pleasure that they turn around, no longer living wrong but living right—really living?
My condolences to a president who, after the death of his first wife, commuted daily from his Delaware home to the Senate, to be a parent to his sons.

Congressional UAP/UFO Hearings Part 2; Napkin Calculation

We continue from Congressional UAP/UFO Hearings Part 1.

Reminder. This discussion requires that tic tacs are alien spacecraft, or from some parallel universe or hyperspace related to “here”, which may be false.

The tic tac descends from 80,000 feet  to near sea level in less than a second, or a few seconds, without breaking a sweat, which is attributed to advanced technology. What about the air? If it is a physical object, it pushes air.  A napkin calc follows, with these simplifications:

  • Tic tac is cylindrical, 15 meters length by 5 meters diameter, with domed ends.
  • Long axis is aligned with  the direction of travel.
  • Weight of atmosphere above 80,000 feet is negligible.
  • Atmosphere is 100% monatomic nitrogen, no oxygen.
  • Collision of nitrogen  with the tic tac is perfectly elastic; the tic tac is not heated by the collision. The atom gains energy; the energy of the tic tac is unchanged.
  • The nitrogen behaves according to simple kinetic theory, while actually it would become a plasma.  It has a temperature.
  • The result is an estimate of the energy used, “work”, to push the atmosphere out of the path of the tic tac in the descent from 80,000 feet to near sea level.
  • The calc is for 80,000 feet in 1 second, which is then scaled.

Spoiler. We should see something resembling an elongated nuclear explosion. If you’re not math inclined, skip to the end table.

Air pressure at sea level is 14.7 pounds per square inch. This is the weight of a square column of air 1 inch wide, mostly contained below 80,000 feet.

14.7 lbs/inch^2 = 22800 lbs/meter^2  = 207,000 kilograms over the area of the tic tac end cap, which is 19.53 meter^2. This is the total mass of the air displaced by the tic tac in its journey from 80,000 feet.

To approximate the reduction of momentum transfer of the domed ends compared to flat ends, 207,000 kg is reduced by 1/3.

The atoms of what was an air column acquire momentum of

p = 2.24 * 10^10 kilograms–meters/second

The kinetic energy of this mass is

E_total = p^2 / 2m = 1.9 * 10^15  Joules

The number of moles of what was the air column = 6.9 * 10^6 moles.

Multiplying by Avogadro’s number, the number of atoms is

N = 4.15 *  10^30

The average energy of an atom after collision with the tic tac is

E_one atom = 1.9 * 10^15 / N = 4.6 * 10^-16 Joules

Where K = Boltzmann’s constant, and T  is the Kelvin temperature, the average kinetic energy of a single atom is

E = 3/2 * KT

The temperature is

T = 4.6 *10^-16 / ( 1.38 * 10^-23 )  =  2.2 * 10^7 degrees Kelvin

= 30 million degrees Fahrenheit

TNT equivalent:

One ton of TNT is equivalent to  1.9 * 10^15 Joules of energy

The former air column has acquired energy equivalent to 460,000 tons of TNT.

Table

16 miles / second,  Mach 80,     30,000,000 F,   460,000 tons TNT

8 miles / second,  Mach 40,        7.5 million   F,     125,000 tons TNT

4 miles / second,  Mach 20,        2 million F,            31000 tons TNT

The calc is useful for a craft traveling at the velocity of thermal atoms. At slower speeds, this approximation becomes inapplicable.

We studied the air because we know more about air than tic tacs. What have we learned?

To be continued shortly.

 

 

 

 

 

 

 

 

 

 

 

 

Att: Larry Gagosian; A Painting for Today – Trash Talk

Trash Talk, 30 x40″, oil on canvas.

A nostalgia piece,  inspired by a time when littering, not global warming or mass shootings, was a matter  of concern. That such a time existed is, of course, imaginary.

For puzzlers: A media logo, perhaps the most beautiful, is hidden in the painting.

Larry, you can call me any time.

Congressional UAP/UFO Hearings Part 1

(CNN) Officials and lawmakers push for more government transparency on UFOs.

All three witnesses provided testimony of unprecedented credibility. Their participation in a quasi-judicial process demands respect. It demands regard of David Grush as an honest broker of facts, until proven otherwise.

Carl Sagan said, “Extraordinary claims require  extraordinary proof.” The testimony does not by itself reach that standard. In the case of David Grush, it contradicts my understanding. I wonder if participants in relevant SAPs have themselves been deceived by excessive classification, robbing them of understanding their own activities. The U.S. has been collecting adversary aircraft since 1942,  in the same time frame as claims about alien spacecraft.

Similarly, one could  pick apart the gimbal camera in the F-18 targeting pod, or the alleged sloppiness in analyzing recovered materials.  But for the first time, these issues do not subjectively diminish human testimony to the point of disregard. For the first time, we are faced by the inescapable question: What if it is all true?

The media tend to mix up the relevance of areas of knowledge. UFOs are not a question for aerospace engineering, which relies on Newton’s laws of motion — classical mechanics.  Only in a few  esoteric areas does aerospace touch on modern physics:

For practically everything else, aerospace relies on fields with mostly classical master equations:

This means that if you gave flying saucer parts to Boeing, Lockheed-Martin, or Northrup-Grumman, their engineers wouldn’t know what to do with them. It is a problem of modern physics. They could hire outside physicists, but there is a  catch.

Contract physicists work with existing theories. No valid existing theory offers a hint at how a  flying saucer might work. There have been many attempts; the floor is littered with broken theories that that fail to predict what is already experimentally verified.

You have to be smart to be any kind of physicist. The hierarchy of achievement is a cruel reminder to those blessed with extreme intellects, of the rarity of extreme achievement. Ignoring the hundreds of years of patient mathematical advance that enabled, there is a hierarchy:

  • At the top,  Newton and Einstein.
  • Other 18th and 19th century giants.
  • The small group of  the Thirty Years that Shook Physics, and less celebrated heroes.
  • Developers of Second Quantization — QED,  the Standard Model, and the Particle Zoo.
  • Mere Nobel Prize winners, from astrophysics to condensed matter physics.
  • People who have managed to Do Something.
  • People with doubtful theories that cannot be fully dismissed.
  • Those who teach, managing to pass on the knowledge, which is no small feat.
  • Industrial physics.
  • Popularization of physics.

In this cruel-to-the-ego list, building the Bomb counts for little. These days, it’s considered an undergraduate subject.

So Boeing can’t just hire the brains to crack the UFO  problem. Their custody of crashed UFOs is pointless. Nevertheless, propelled by that which cannot be dismissed, the next article will speculate on:

***How do UFOs work?***

and why we are unlikely to find the answer on our own terms.

To be continued shortly.

 

 

Cluster Munitions for Ukraine

(CNN) What are the cluster munitions the US is expected to supply Ukraine and why are they so controversial? Quoting,
The United States is expected to announce a new military aid package for Ukraine on Friday that will include cluster munitions for the first time, defense officials have told CNN.
In January, in Tanks for Ukraine, NFG? I wrote,
The Marines have turned in their tanks, mandated by their new littoral mission. A general principle can be distilled: Stealth multiplies lethality. Is it impossible to employ armored spearheads in Ukraine? If the abysmal performance of the Russian army continues, it is conceivable, though such assumption receives warning from von Clausewitz. Paraphrasing, the  enemy does not do what you want him to do; he does what he wants to do, which could be competence with the 9M133 KornetCluster munitions would be far more useful to Ukraine.
With little change, the argument of Tanks for Ukraine, NFG? , which is based on the characteristics of the modern ATGM, can be extended to tank vulnerability to air power when air superiority is lacking. It does not extend to artillery,  or cluster munitions delivered by artillery, which has greater possibilities of dispersal and camouflage.
Cluster munitions will be an effective force multiplier for Ukraine.

Sloppy CNN: Scientists find new clue in what led to megalodon’s demise

Sloppy CNN: Scientists find new clue in what led to megalodon’s demise. Quoting,
Through an analysis of fossilized megalodon teeth, scientists have discovered the extinct shark was partially warm-blooded, with a body temperature around 7 degrees Celsius (44 degrees Fahrenheit) warmer than estimated seawater temperatures at the time, according to a study published last week in the journal Proceedings of the National Academy of Sciences.
This is wrong; 44 should be 12.6. It seems someone mistakenly  used the formula for Celsius to Fahrenheit temperature conversion:
Temp_F  = Temp_C *9÷5 + 32
To be converted is the relationship of the Celsius unit of measure to the Fahrenheit unit of measure, which is:
Fahrenheit degrees  per Celsius degree = 9÷5
The number 32 must not be added.
This is sloppy journalism.

(CNN) Large pieces of the doomed Titan submersible arrive in Canada

(CNN) Large pieces of the doomed Titan submersible arrive in Canada.

See Titan Sub Implosion: The Knowledge Stockton Rush Ignored; Snap-Buckling Failure Mode.

The design was defective in many ways, all of which could cause implosion. One feature can be identified as most  probable, where the titanium end bells joined the carbon fiber tube.

The deep sea is cold. Under temperature change, from surface to depth and back to surface,  the two materials  contracted and then expanded at different rates —  with differing coefficients of expansion.  When, at the factory, the end bells were attached with epoxy cement, all the  parts were at factory ambient temperature. At any other temperature, there was stress between the  parts.

  • Each dive comprised a cycle of thermal and mechanical stress on the epoxy joints.
  • After some number of dives, microscopic cracks began to grow in the joints.
  • Cracks concentrate stress, which is why cracks usually grow.
  • At some cycle, the epoxy failed  in some region of the joint.
  • An area of the cylinder then lost support from the end bell. This area of the cylinder also experienced the most flexure, so it was the most fatigued.
  • Implosion of the cylinder began there, and spread longitudinally in just a few milliseconds.

One might expect that the end bell side of the joint was a flange, with a smaller diameter extending into the carbon fiber tube. Sometimes this is done to achieve a thermal shrink fit, so that the joint is always under compression,  which makes it stronger. This was not done. The end bell began with a flat adapter ring that was simply glued to the end of the tube.

It is possible to join materials with different coefficients of expansion, by use of a slightly elastic gasket, a flange, and constant compression of the joint with tension bands. This was evidently too much bother for Stockton Rush. Even if this were done, it is likely the Titan would have eventually been  claimed by snap buckling.

Which brings us back to safety culture:

(CNN) Missing Titanic sub crew killed after ‘catastrophic implosion’

 

 

Titan Sub Implosion: The Knowledge Stockton Rush Ignored; Snap-Buckling Failure Mode

See  A Review on Structural Failure of Composite Pressure Hulls in Deep Sea.

Quoting,

With the increase of the diving depth of the submersibles and the thickness of the composite pressure hull, the structural failure of the pressure hull may change from the overall buckling to gradual material failure. As a result, the design concept of the structure has to be changed. In addition, the large thickness composite pressure hull used in the very deep sea also has its unique failure mode, snap buckling. This problem appeared in the application of deep sea pressure pipelines in the 1980s, and has received more attention and research since then.

For specifics of the Titan design, see Composite submersibles: Under pressure in deep, deep waters. The thickness of the hull was 5 inches.

A little bit of intuition.

  • The metal of a conventional hull has strength in all directions.

  • A carbon fiber / epoxy hull has high strength within the fiber layers, but not between them.

  • The thicker the hull, the more stress between the layers.

Hence, SNAP!
