Columnar Rock Layers at Yellowstone

Just a quick posting of a wonderful rock formation in Yellowstone National Park. Note the two layers of columnar lava rock. Recall the Devil’s Causeway in Northern Ireland or Devil’s Tower a couple of hundred miles to the east of Yellowstone in Wyoming. That Devil was a hard working demon.

Slow solidification and shrinkage of the cooling lava flows from earlier vulcanism led to this columnar structure. There is a pull-off across the road next to what must be the upper layer where the photo was taken. I skipped across the road to get a closer look. After 5 minutes I noticed the sign warning not to go next to the formation due to the danger of falling rock. At least there wasn’t a bison standing there as well.

The Expanding World of Bentonite

In researching a newspaper article on the expansive clay bentonite, I’m reminded of the rich geochemistry and mineralogy of silicates and aluminates. A visit to the Wikipedia page for silicates reveals a taste of the variety of silicate structures. The clays under discussion here are of the sheet silicates also characterized as phyllosilicates. When the word ‘bentonite’ is used, it is understood to mean a clay with at least 70 % montmorillonite.

Image: Link. The platy nature of clays.

The two clays mentioned here are layered structures comprised of silicate tetrahedra (T) and aluminate octahedra (O). Kaolinite would then be classed as a TO bi-layered structure and montmorillonite is classed as a TOT tri-layered structure. The figure above shows the platy, stacked nature of the phyllosilicates.

Silicate minerals with a single, isolated SiO44- groups are called orthosilicates. These SiO44- units can be joined at the vertices to form single and double chains, rings, sheets and 3-D networks as in quartz. In the case of chains, etc., the silicon atoms are bridged with oxygen atoms.

Presently I am writing a piece about the sciency aspects of bentonite, a clay responsible for expansive soil. A local McBurger restaurant has closed temporarily due to structural problems caused by expansive soil which is symptomatic in the region. For geographical context we are in north central Colorado between Cheyenne, Wyoming, and Denver, Colorado. The presence of troublesome bentonite-containing expansive soils in the area is well known. In fact, there are many bentonite mines in Wyoming, one with milling operations in Casper, WY.

According to the Wyoming Mining Association, Wyoming has 70 % of the world’s and 93 % of the USA’s known bentonite deposits.

Bentonite can be harmful to roads and building foundations but also serves as an important raw material. It is used primarily in drilling muds, cat litter, cosmetics, pharmaceuticals, animal feeds and other applications.

The class of expansive clays relevant here are the smectites. Bentonite is a smectite and has mineral composition rich in the montmorillonite member of the smectite group. In short, montmorillonite can attract waters of hydration to a great extent depending on the cation sub-type of the montmorillonite. The sub-types include Na+, K+, Ca++, Mg++, Fe++ counter-ions. A common cation in montmorillonite is sodium cation. The high water solubility of sodium salts in general allows for it’s replacement by other cations.

The montmorillonite unit structure consists of 3 layers similar to the stacking of an Oreo cookie. The inside cream layer consists of a sheet of aluminate octahedra. The two sandwiching cookie layers are sheets of silicate tetrahedra. The net effect is that the internal surplus negative charge carries through to the exterior surface of the sandwich. This charge attracts water layers and cations that will coordinate to the cookie surface to balance the charge. This attraction to cations and water leads to expansion of the unit structure the mineral and therefore swelling of the bulk material.

Kaolinite is comprised of bi-layers of a tetrahedral silicate sheet intimately bound to an aluminate sheet with no intervening layer of hydrates. The direct stacking of the kaolinite plates absent the water layer physically prevents water from migrating between plates and leading to swelling. Kaolinite is not an expansive clay.

Image: Cambridge Core (Paywall) , a ball and stick drawing of a Kaolinite silicate layer on top of a octahedral aluminate layer.

The pottery clay familiar to most of us is comprised mostly of kaolinite. While not a smectite, kaolinite (above) has just a single tetrahedral silicate layer connected to an octahedral aluminate layer to make a flat platy structure.

What’s Worse- Authoritarianism or Socialism?

Over the decades I’ve listened patiently to conservatives, especially the elected GOP types, spout off about liberal proposals or programs as being “socialism.” The very word carries a strong revulsion in them, enough to cause right wingers and even some centrists to recoil in horror. In common usage, the word is almost spat out of their mouths with the same abhorrence that one might vocalize in reference to a Old Nick himself. The mere utterance of the word should be enough to demolish liberal proposals like affordable healthcare or Pre-K programs.

My station in life has been in the field of chemistry, not psychology, so I am hardly qualified to clinically diagnose what psychology lies behind this vigorous and frequent epithet. Despite the mountain of clinical ignorance I reside under, I can offer a few observations in the not-so-subtle form of questions.

  • What event led to the huge corrosive and emotional investment many conservatives have with socialism?
  • How is it that I can read comments from conservatives in social media or network news wherein acute criticism is levied on socialism, but such criticism is not expressed on authoritarianism? Are they OK with authoritarianism or just unwilling to invite comparison?
  • Do conservatives still believe that socialism automatically means Soviet-style socialism? Didn’t the Soviets prove to the world that Soviet socialism doesn’t work? Many of us were paying attention to this event, weren’t you?
  • Could it actually be that conservatives view socialists as freeloaders wanting to suckle on the generous American teat?

Without food, shelter or skills, the world is a dangerous place for those not born into wealth or without a record of good luck. The sort of dilute socialism in practice in the USA since FDR brought us a social safety net has had many positive effects. The overall effect is that it has reduced some of the harshness of life for a great many.

Perhaps the beef that the moneyed class has with liberal democracy is that they are prevented from accumulating gilded-age wealth by every means possible? They want absolute control of markets and labor. The role of government is to arrange consumers for easy pickings, like fish in a barrel. In the biological world, unlimited growth is called cancer. The religion of shareholder value sets the pace for endless growth, despite the mathematical absurdity of it.

The 2nd Amendment-banging ultra-right wingers in camouflage britches have long been eager to explain that they were prepping for oppression by a tyrannical government. Well boys, the tyrannical government is here here! Now whatcha gonna do?

Tornado Simulation

Being retired and an avid YouTube viewer I recently blundered into a group of videos presenting supercomputer simulations of tornado formation and evolution. The work is done by Dr Leigh Orf and coworkers.

Image credit: MDPI. Dr. Leigh Orf, The Cooperative Institute for Meteorological Satellite Studies (CIMSS), University of Wisconsin, Madison, WI 53706, USA. Atmosphere 2019, 10(10), 578; https://doi.org/10.3390/atmos10100578

In an article titled A Violently Tornadic Supercell Thunderstorm Simulation Spanning a Quarter-Trillion Grid Volumes: Computational Challenges, I/O Framework, and Visualizations of Tornadogenesis, Orf describes his supercomputer simulation results from a program written in Fortran95. I gather that development of the software was quite a feat.

What caught my attention was the visual and computational appearance of multiple vortices in the early stages of tornado formation. This can be seen in Orf’s simulations. As a tongue of in-flowing air streams towards the central vortex it abruptly swerves upward and in doing so begins to repeatedly spawn lesser vortices that in the upwards flow that will coalesce with one another and combine with the core vortex. The formation of wispy clouds flowing into the rising, low pressure air funnel renders some of the flow field visible, but not nearly as much as the simulation.

Image from the National Weather Service. A rendering of an idealized anvil cloud.

As the supercell matures, the upward lofting of moist air slows, spreading horizontally and flattening the top to give the characteristic flat top of an anvil cloud. Air cooled at high altitude begins a down wash to the ground carrying precipitation with it. This down wash hits the ground and spreads horizontally causing the so-called first gust prior to the arrival of the storm. You may have noticed the arrival of a strong gust of cold air just before a major storm begins in earnest.

Image from Wikipedia. Notice the position of the mammatus clouds on the trailing edge of the storm. The tornado is towards the leading edge of the storm.

The Massive Problem of “Massive”

An actual lamentation. A pet peeve of mine is the wanton and extravagant overuse of the word massive. It seems to me that the word should be limited to physical things that have mass or weight. We can all agree that Mt. Everest or an asteroid is massive, you know, dense and heavy. But what about as an adjective for a large void? Then there is massive as an adjective for an explosion?

One of the more egregious misapplications of the word arises as a description of a hole, e.g., massive hole. Oh, good gravy. Open the damned thesaurus for a synonym. Ask Mr Google-

The best word for a big hole depends on its shape and how it was made.

Pit: A deep, natural or man-made hole in the ground.

Crater: A large, circular bowl-shaped hole (e.g., from an explosion or meteor).

Chasm: A deep, massive crack or gorge in the Earth’s surface (e.g., a steep-sided rift).

Abyss: A bottomless or unfathomably deep hole or void.

Sinkhole: A natural depression or hole caused by the collapse of surface layers.

For incredible scale or size: Merriam-Webster Thesaurus lists colossal, enormous, gigantic, immense, vast, mammoth, gargantuan, and titanic.

For solid weight or bulk: Hefty, bulky, ponderous, weighty, and substantial are excellent choices.

A close second is massive explosion. The main idea in using an adjective to modify an impressive explosion is to emphasize the power of the thing. Again, Mr Google suggests words depending on the specific context of the sentence, you can choose from these related terms:

  • For pure destructive impact: Blast, detonation, or blowup.
  • For a catastrophic or earth-shattering event: Cataclysm or catastrophe or catastrophic explosion.
  • For fiery or highly energetic events: Eruption, flare, or supernova (for astronomical events).

The folks who write or speak on broadcast or social media seem to be the big offenders. As a result it is unlikely this demographic will see my pathetic blogging on the matter.

Don’t be lazy. Pick appropriate alternatives to massive that conform to the reality of the subject.

The Trump Coup d’Etat Shifts Into Low Gear

Search results from Googling “$350 billion attack on communism”-

“House Speaker Mike Johnson is pushing for an additional $350 billion in military spending for the Pentagon, on top of an already approved record-breaking $1.1 trillion defense budget. Speaker Johnson explicitly stated that a portion of these funds is needed for “fighting communism on our own shores”. This comports with what I’ve read elsewhere.

Speaker Johnson is a punk and a POS.

More of the same from the Republican fearmongering playbook. They lurch from the unjustifiable attack on Iran to a $350 billion uptick in action against the American republic. Somebody convince me that we can elect our way out of this death spiral. This is a coup d’etat in slow motion. This festering blend of Trump cult, Christian evangelical Zionism, testosterone bravado, and libertarian utopian fantasy is free to bungle forward while the fearful Republican majority looks on.

Critical to their coup is that democrats and liberal independents will obey the law without violence while MAGA republicans bog the system with lawfare. Their cunning legal appeals give the ultra conservative in the Supreme Court to rule in favor with precedent setting decisions favoring the gaggle of MAGA Republicans. The press must begin to focus on the Heritage Foundation and its members who provided Project 2025.

Trump is like a corrosive gas. He expands beyond precedent on presidential norms, and like a corrosive, his actions corrode the departments who have to deal with it. He tramples norms and waits for the courts to tell him no. All the while, his behavior seems to display increasingly disabled thinking and disregard for demonstrable facts.

Here is the question.

By maintaining civil obedience during public displays of protest, do we of the loyal opposition do our Democratic Republic a disservice by staying away from a show of physical force or lawfare? Must we remain “peaceful” and witness the fall of the American empire. The Democratic Party seems incapable of finding good candidates and getting them elected at the necessary.

Are we liberal patriots or are we sheep?


Yammering Idiots

Noisy idiots have been a problem throughout history. What to do with precocious citizens with half-baked yet strangely appealing ideas? The notion that jobs are being taken by immigrants is an enduring and popular fancy. Another is that the federal government is merely a front for a squad of hidden mandarins quietly controlling the government from a bunker.

So, where do I get off calling people idiots? Is it not possible that I am an idiot as well? Yes, I’m anxious to clear the air and admit to my own idiocy. No point in denying it. As a lifetime member of the set of all idiots, I’ll offer a defining quality of idiocy.

===============================

The rest of this post is cut and pasted from Facebook. I don’t know who wrote it but here is the link.

Umberto Eco was a scholar — a man who spent sixty years inside libraries, inside ancient manuscripts, inside the deepest questions human beings have ever wrestled with. How do we make meaning? How does a symbol become a belief? How does a word become a world?

He wrote The Name of the Rose — a murder mystery set inside a 14th-century monastery, where the most dangerous weapon wasn’t a sword. It was a book. And the most dangerous idea wasn’t heresy.

It was forbidden knowledge in the hands of the unprepared.

He understood, better than almost anyone alive, what happens when information moves without wisdom to carry it.

So in June 2015, when Umberto Eco accepted an honorary degree from the University of Turin and turned to face the journalists in the room, what he said wasn’t a prepared speech.

It was a warning.

The room went quiet.

Because everyone in it knew he wasn’t being cruel. He was being precise.

For most of human history, spreading an idea required effort. A book had to be written, edited, printed, and earned its way into hands. A journalist had to answer to editors who asked: Is this true? Can you prove it? A voice had to build credibility slowly — through knowledge, through time, through the hard work of being right more often than wrong.

That process wasn’t perfect. Important voices were shut out. Power shaped what got heard. The gatekeepers had their own agendas.

But there was friction. And friction — it turns out — slows things down just long enough for truth to catch up with speed.

Now that friction is almost gone.

A rumor written in anger at midnight can reach a million people before sunrise. A post with no sources, no context, and no accountability can be shared more times than any correction will ever be. Outrage travels faster than nuance. A confident lie moves faster than a careful truth.

Eco understood this — not because he hated technology. Not because he was a bitter old man longing for simpler times.

He understood it because he had spent a lifetime mapping exactly how human beings get deceived. By symbols. By certainty. By the seductive confidence of a voice that sounds like it knows.

His warning wasn’t that everyone having a voice is wrong.

Every person deserves to be heard. The democratization of expression — the idea that you no longer need wealth or institutional power to reach an audience — is genuinely, powerfully good.

His warning was about something quieter. The collapse of the space between having an opinion and having expertise. Between speaking and being believed.

We feel that collapse every single day now.

In the health post written with total confidence by someone with no medical training — shared a hundred thousand times by people who trusted the tone, not the facts. In the political story that races ahead of the truth. In the moment satire gets mistaken for news, and no one notices until the damage is done.

The algorithm doesn’t reward careful.

It rewards engaging. And “engaging” — too often — means shocking, confirming, or enraging.

Umberto Eco died in February 2016. Just eight months after that warning. Just as the world he described was beginning to fully unmask itself.

He never saw what followed.

But his words survived. And they don’t read like criticism anymore.

They read like a map.

So the next time something lands in your feed and every instinct says share this now — pause. One breath.

Ask: Who said this? Why does it make me feel this way? Is the confidence of the writing a substitute for evidence?

Not because you distrust everything. Not because truth doesn’t exist.

But because the single most powerful thing any of us can do in an age of noise — is slow down long enough to think.

That, Umberto Eco would say, is not weakness.

That is the only thing standing between information and wisdom.

Stray Radiation from CBCT Scanner

In preparation for a dental implant I “took a ride” in a Cone Beam Computed Tomography, CBCT, x-ray scanner with my Geiger counter. I did the scan with a small Geiger counter hidden in my pants pocket. Why hidden you ask? Because I didn’t want to spook the dental assistant and dentist into paroxysms of fear and loathing over bad publicity. I was just curious about scattered radiation.

Source: Google. A CBCT, Cone Beam Computed Tomography panoramic cone beam x-ray scanner.

I’ve had three rounds of radiation, two PET scans and several dozen IMRT CT scans so no worries here about the brief x-radiation exposure as an old guy. Between cosmic rays, solar UV, uranium in the granite, radon with all of her daughters, blasting alphas, betas, gammas and finally muons from the sky, we’re constantly bathed in environmental radiation.

Image from Wikipedia. Schematic of CBCT machine.

Looking how the cone beam spreads (above) from source to detector, perhaps it is no wonder that some of the x-rays exceed the cone in the diagram.

The background counts per minute following the x-ray was 22 cpm, average for around here. During the x-ray, the counts peaked at 19,838 cpm over ~30seconds for a 902 cpm times background.

I take radiation seriously, but the fact is that it is a stochastic hazard so correlating cancer with exposure is tricky.

According to Google AI with search query “is radiation hazard stochastic?” being stochastic means that-

I agree with what Naomi Klein said

I started to post the content below on Facebook but somehow the old saying about casting your pearls before the swine began to echo inside my pointed head. My Facebook friends aren’t swine obviously -I love all of them- but it is a limited distribution.

The same class of business geniuses who off-shored American manufacturing are now telling us that their AI technology will relieve people of menial labor. This ‘menial labor’ is what keeps food on the table of millions of human beings. Yes, in theory the AI-unemployed could retrain to work in information technology, but seriously, that’s not going to happen. AI is looking to replace computer programmers too as well as white collar management level jobs. Desktop computers devastated the job market for secretarial and typing pools in the 1980s. The result is that information workers spend much of their time performing typesetting and formatting tasks in addition to their to jobs.

Ever try to but tickets online? Invariably you must download an app and enter commercially valuable information like your name, email address, phone number and credit card number so their algorithm can place you in a barrel with the rest of the fish. From there you will be set up for personalized marketing and sale to parts unknown. All to get admittance a single time with over priced tickets. Need to ask a question? Just forget it.

Business school graduates are taught that properly ambitious people should be engaged in bringing down existing paradigms. Okay, fine, I get it. Any economic bubble will reward early adopters with a greater opportunity for wealth. It was true with any gold or land rush in history and is part of human nature. But that does not mean that the government is supposed to stack the deck for business and against the public good by using its immense resources to force the public to ‘cooperate’ and line up to have their pockets picked.

The trickle down economics theory pushed by Ronny Reagan remains in the imaginations of many today. It was BS then and is BS today. When organizations greet an uptick in profits, they have a choice of what to do with it. They can put it back into their businesses for improvements or they could hire more workers to meet the demand. But this often requires new customers who may not be there. Added profits are just as likely to banked off-shore or go into tax shelters. You only hire more people if demand requires it.

Power is in the ability to allocate resources. The American plutocrats of today like the ‘tech bros’ exploit the automatic admiration of the public as well as their wealth to steer the economy as as they please.

Pucker Factor Relaxing in LA with Runaway Tanks of MMA

Sphincters are beginning to loosen in LA with the MMA fiasco tapering into a more banal conclusion. Here MMA does not refer to Mixed Martial Arts. It is the abbreviation for methyl methacrylate, a reactive monomer for the production of PMMA, poly[methyl methacrylate], often called acrylic or Plexiglass. Plexiglass is a generic name like “Xerox” or “Velcro” but it is also trademark.

There was a lot of loose talk about a possible explosion, a B.L.E.V.E., detonation, and vapor plumes. I would categorize this incident as a low frequency, high consequence event.

This being LA, I wonder how long it will take for a movie or miniseries to come out? I vote for Brad Pitt and Scarlett Johansson to star in it and produced by Steven Spielberg. The lead investigator for the US Chemical Safety Board would be Tig Notaro.

Cooling a large tank of liquid on the outside surface is one of the least effective methods of cooling bulk material. Ideally, a vessel would have an immersed heat exchanger for efficient cooling with agitation and possibly with a cooling jacket. Properties of MMA: 100.3 to 101 oC boiling point; Flash Point 10 oC; vapor pressure of 29 to 37 mm Hg, It is highly flammable.

It is not uncommon for an industrial park to be near a residential area. But, in my estimation, a chemical plant storing something like bulk MMA near a residential area is not the best situation. You have to ask if the zoning people knew about this proximity situation or if such was even contemplated. This is likely to lead to state legislation or city ordinances. Everyone likes to rush into locking the barn door after the horse has run loose.

According to Wikipedia, GKN Ltd is a British multinational automotive and aerospace components business headquartered in Redditch, England. They manufacture what are called military “transparency systems”, meaning canopies, windshields and windows.

The MMA in the tanks is converting to a big block of acrylic polymer. If you’re interested in buying it, I’ll bet they will give you a good deal on it …
