Relativity’s twin paradox explained, and why time is at right angles to space.

Leave a reply

One of the most famous paradoxes of physics is explained wrong — always. It makes people feel good to think they understand it, but the explanation is wrong and confusing, and it drives young physicists in a wrong direction. The basic paradox is an outgrowth of the special relativity prediction that time moves slower if you move faster.

Thus, if you entered a spaceship and were to travel to a distant star at 99% the speed of light, turn around and get here 30 years, you would have aged far less than 30 years. You and everyone else on the space ship would have aged three years, 1/10 as much as someone on earth.

The paradox part, not that the above isn’t weird enough by itself, is that the person in the spaceship will imagine that he (or she) is standing still, and that everyone on earth is moving away at 99% the speed of light. Thus, the person on the spaceship should expect to find that the people on earth will age slower. That is, the person on the space ship should return from his (or her) three year journey, expecting to find that the people on earth have only aged 0.3 years. Obviously, only one of these expectations can be right, but it’s not clear which (It’s the first one), nor is it clear why.

The wrong explanation appears in an early popular book, “Mr Tompkins in Wonderland”, by Physicist, George Gamow. The book was written shortly after Relativity was proposed, and involves a Mr Tompkins who falls asleep in a physics lecture. Mr. Tompkins dreams he’s riding on a train going near the speed of light, finds things are shorter and time is going slower. He then asks the paradox question to the conductor, who admits he doesn’t quite know how it works (perhaps Gamow didn’t), but that “it has something do do with the brakeman.” That sounds like Gamow is saying the explanation has to do with deceleration at the turn around, or general relativity in general, implying gravity could have a similarly large effect. It doesn’t work that way, and the effect of 1G gravity is small, but everyone seems content to explain the paradox this way. This is particularly unfortunate because these include physicists clouding an already cloudy issue.

In the early days of physics, physicists tried to explain things with a little legitimate math to the lay audience. Gamow did this, as did Einstein, Planck, Feynman, and most others. I try to do this too. Nowadays, physicists have removed the math, and added gobbledygook. The one exception here are the cinematographers of Star Wars. They alone show the explanation correctly.

The explanation does not have to do general relativity or the acceleration at the end of the journey (the brakeman). Instead of working through some acceleration, general relativity effect, the twin paradox works with simple, special relativity: all space contracts for the duration of the trip, and everything in it gets shorter. The person in this spaceship will see the distance to the star shrink by 90%. Traveling there thus takes 1/10th the time because the distance is 1/10th. There and back at 99% the speed of light, takes exactly 3 years.

The equation for time contraction is: t’ = v/x° √(1-(v/c)2) = t° √(1-(v/c)2) where t’ is the time in the spaceship, v is the speed, x° is the distance traveled (as measured from earth), and c is the speed of light. For v/c = .99, we find that √1-(v/c)2 is 0.1. We thus find that t’ = 0.1 t°. When dealing with the twin paradox, it’s better to say that x’ = 0.1x° where x’ is the distance to the star as seen from the spaceship. In either case, when the people on the space ship accelerate, they see the distance in front of them shrink, as shown in Star Wars, below.

Star Wars. The millennium falcon jumps to light speed, and beyond.

That time was at right angles to space was a comment in one of Einstein’s popular articles and books; he wrote several, all with some minimal mathematics Current science has no math, and a lot of politics, IMHO, and thus is not science.

He showed that time and space are at right angles by analogy from Pythagoras. Pythagoras showed that distance on a diagonal, d between two points at right angles, x and y is d = √(x2 + y2). Another way of saying this is d2 =x2 + y2. The relationship is similar for relativistic distances. To explain the twin paradox, we find that the square of the effective distance, x’2 = x°2 (1 – (v/c)2) = x°2 – (x°v)2/c2 = x°2 – (x°v/c)2 = x°2 – (t°2/c2). Here, x°2 is the square of the original distance, and it comes out that the term, – (t°2/c2) behaves like the square of an imaginary distance that is at right angles to it. It comes out that co-frame time, t° behaves as if it were a distance with a scale factor of i/c.

For some reason people today read books on science by non-scientist ‘explainers.’ I These books have no math, and I guess they sell. Publishers think they are helping democratize science, perhaps. You are better off reading the original thinkers, IMHO.

Robert Buxbaum, July 16, 2023. In his autobiography, Einstein claimed to be a fan of scientist -philosopher, Ernst Mach. Mach derived the speed of sound from a mathematical analysis of thermodynamics. Einstein followed, considering that it must be equally true to consider an empty box traveling in space to be one that carries its emptiness with it, as to assume that fresh emptiness comes in at one end and leaves by the other. If you set the two to be equal mathematically, you conclude that both time and space vary with velocity. Similar analysis will show that atoms are real, and that energy must travel in packets, quanta. Einstein also did fun work on the curvature of rivers, and was a fan of this sail ship design. Here is some more on the scientific method.

The Ukraine war could go for years. Don’t make a famine.

Leave a reply

Russia is a collapsing, corrupt state with no meaningful elections. It is also the biggest exporter of food, fertilizer, gas, and oil. Nearly 2 years ago, it invaded Ukraine, another collapsing, corrupt, food-exporting state with suspended elections.

Both countries are in the midst of demographic collapse, with Ukraine worse off. Ukraine was invaded though, and thus has the better claim to our support. Then again Russia has atomic bombs. It’s also the largest exporter of wheat (or was), while Ukraine is only the 5th largest (or was before the war). The other three big exporters are the US, Canada, and France. They have benefitted financially, but don’t have near enough output to make up for lost Russian and Ukrainian production.

Ukraine’s grain terminals in flames, Odessa..

Food and energy prices have gone up, world wide, and will probably continue to rise as the war stretches on. This could lead to a global famine and mass starvation, particularly in the poorest areas of Africa, the Mid East, and India. Unfortunately, the war is popular and patriotic, in Europe, Russia, Ukraine, and the US. It’s good business for our armaments industry, and for our recent mega-farmers (like Bill Gates). Also, for our political and spy class. They spend with little government oversight, and just recently misplaced $16 billion. Surely some of that lost money snuck back to the CIA and our politicians’ pockets. We’d have oversight, but “there’s a war on.”

As wars go, the death toll is low, a total of 354,000 dead and injured on both sides, as revealed by recently leaked documents. This is a small fraction of the countries population. Russia has lost 223,000 soldiers killed or wounded, 0.2% of the population, while the Ukrainians had lost 131,000. That’s 0.3%, many of them civilians. The death rate in the two countries during this time was 3.1 million people, 1.8% of the total, mostly from heart disease, accidents, and alcoholism.

The Ukrainian population. Lots of retirees, few kids, very few of military age. This is a disaster, not a country.

Even more destructive to Russia and Ukraine is the demographic collapse. The fertility rate in Russia is 1.5 child per woman, up fro 1.2 in 2000. For a stable population at low infant death, you need about 2.1 children per woman. Russia has had this low rate for a generation, at least 30 years. The net result is that we can expect that Russia’s population will drop by a third or so over the next generation, about 50 million. In Ukraine the fertility rate is even lower, 1.21 per woman, up from 1.1. It’s been this way for 30 years, the equivalent of killing off 1/2 of the population. Aside from leaving the countries full of old people, with no one to do the work, the demographic collapse is producing a cultural shift that virtually guarantees the breakup of Ukraine and the Russian federation. Europe also has this problem, but they have immigration, and that helps a little. Russia has no immigration, and recently resorted to kidnapping Ukrainian children.

The loss of Russian and Ukrainian exports means famine for the poor importers and food inflation for all.

The coming food and energy shortage is likely to lead to mass migration, I expect. Europe has stopped taking delivery of Russian food and energy, in solidarity with Ukraine. Meanwhile Russia has been destroying Ukrainian fields and food infrastructure. Russia ruined a dam last month, flooding Ukraine’s fields, and yesterday destroyed the grain terminals at the port of Odessa,. This was tit-for-tat since Ukraine destroyed a key bridge, and Crimea’s irrigation canal. What’s more, evidence suggests that Ukraine blew up the Nord Stream pipeline — a key source of finance for Russia and Germany. This sort of tit-for-tat escalated to WWI, fueled by a belief, on both sides, that they would win “decisively and quickly.”

The result of WWI is that Germany was the biggest loser, losing men and land, and suffering a killing famine in 1916. It militarized to prevent it happening again, leading to WWII. Germany is the biggest loser of this war, I’d say, aside from Ukraine. I fear it will militarize. Russia invaded Ukraine but claims a need to militarize. Biden’s promise that Ukraine’s will join NATO is a threat to Russia, as is our delivery of F16s, missiles and cluster bombs. We are killing Russians, and Putin doesn’t like it. Add to this, that Ukraine’s claim for independence rests mostly on its Nazi collaboration. For the good of everyone, maybe we can stop adding gasoline to this fire.

Ukraine deserves our support, I think, but that support need not go beyond small-ish arms, energy deliveries, and tariffs on Russian goods. I think we should Ukraine and Russia export food and energy. Even without WWIII, a world famine and a military Germany does no one any good.

Robert Buxbaum, July 20, 2023. When I was a teen, it was a given that war was bad. Now, for some reason, the kids are in for war, especially the more liberal classes. I find this absolutely bizarre.

I’d like to expand the Jones act so more ships can do US trade.

2 Replies

If you visit most any European port city, you’ll see a lot more shipping than in the Midwestern US. In Detroit, where I am, your’ll see an occasional ore boat from Wisconsin, and an occasional tourist cruise, but nothing to compare to German, Belgian, or Turkish ports. The reason for the difference is “The Jones act.”

The port of Istanbul with many ships

The Jones act , also known as “The Merchant Marine Act of 1920”, requires that all ships depositing cargo or people between US ports must be US owned, US built, US captained, US flagged, and at least 70% US manned. This raises costs and reduces options. The result is that few ships can move people or cargo between US cities, and these ships are older and less efficient than you’ll see elsewhere. World wide water traffic costs about 1/8 that of rail traffic per ton-mile, but in the US, the prices are more comparable. The original justification was to make sure the US would always have a merchant marine. The Jones act does that, sort of, but mostly, it just makes goods more expensive and travel more restrictive.

The port of Detroit — we rarely see more than one ship at a time.

Because it does some good, I don’t want to get rid of the Jones act entirely, but I’d like to see US shipping options expanded. Almost any expansion would do, e.g. allowing 50% US manned ships delivering along US rivers, or expanding to allow Canadian built ships or flagged, and ships that are more than 50% US owned, or expanding to any NAFTA vessel that meets safety standards. Any expansion of the number of ships available and would help.

The jones act increase the price of oil transport by a factor of five, about.

Currently, the only exceptions to the Jones act are for emergencies (Trump voided the act during several storms) and for ships that visit a foreign port along the route. This exception is how every cruise ship between California and Hawaii works. They’re all foreign, but they stop in Mexico along the way. Similarly, cruises between Florida and Puerto Rico will stop in Bermuda typically, because the ships are foreign owned. Generally, passengers are not allowed to get off in Puerto Rico, but must sleep on board. This is another aspect of the Maritime act that I’d like to see go away.

Because of the Jones act, there is some US freight-ship building, and a supply of sailors and captains. A new, US ore-ship for the Great Lakes was launched last year, so far it’s been used to carry salt. There is also a US built and operated cruise ship in Hawaii, the “Pride of America,” that makes no stop in Mexico. I’d like to see these numbers expanded, and the suggestions above seem like they’d do more good than harm, lowering prices, and allowing modern container ships plus roll-on-roll-off car transports. Our rivers and lakes are super highways; I’d like to see them used more.

The port of Antwerp – far busier than Detroit.

Another way to expand the Jones act while perhaps increasing the number of US-built and operated ship would be through a deal with Canada so that ships from either country could ply trade on either countries rivers. As things stand, Canada has its own version of the Jones act, called the Coastal Trade Act where Canadian vessels must be used for domestic transport (cabotage) unless no such vessel is available. Maybe we can strike a deal with Canada so that the crew can be Canadian or US, and where built ships in either country are chosen on routes in either country, providing they meet the safety and environmental requirements of both.

Disney was a narcissist, like Trump, Putin, Musk, and Martin Luther King. It’s not a disease.

Leave a reply

Among TV psychiatrists, the universal opinion of Trump, Putin, and Musk, that these individuals are narcissists, a psychological disease related to “toxic masculinity.” Musk, for his part claims the excuse of Asperger’s disease, high-functioning Autism. I half agree with the Narcissist diagnosis, and I’m confused by the Asperger’s claim because I don’t believe these folks are diseased. My sense is they have a leadership personality trait, common in all visionary leaders including Disney, Martin Luther King, and Genghis Khan. I’ve argued that it is important for a president to be a narcissist, and have explained Trump’s vision, “Make America great again” as independence.

Psychological narcissism, short for Narcissistic Personality Disorder, is a disease when it hurts the narcissists life. It is defined as a pattern of exaggerated feelings of self-importance, along with an excessive need for admiration. If it just annoys people it/s a disease, but it’s found among leaders, suggesting it’s not all bad. To get you to follow them, leaders present themselves as mini-messiahs, and try to get you to see them that way. They have a plan, a vision. If it’s successful, they’re visionaries. They fight to bring the vision into reality, which is very annoying to anyone who doesn’t see it or want it. But that’s leadership. Without it nothing big gets done.

Disney’s vision. Not everyone was pleased; quite a few considered him a tyrant.

For the narcissist to succeed, he or she must sell the vision, and his ability to get it done. The plan to get there is often vague and unattractive. These details are shared with only a few. You must see the leader there and yourself too, if you’re to fight for it. Disney was particularly visual, see photo. He got folks to buy into a building a magical kingdom with a private police force, where everyone is happy and cartoon characters glide among the paying visitors.

The majority of those who run into a narcissist reject both the vision and the narcissist. They fear any change, and fear that the success of the visionary will diminish them. For that reason, they run to no-bodies. But some see it, and follow, others throw stones. Disney got state officials to exempt him from state laws, and extend normal copyrights. Others smirked, and worked to stop him, but with less energy: it’s hard to be enthusiastic about no Disneyland. The conflict between doers and the smirkers is the subject of several Ayn Rand books, including The Fountainhead and Atlas Shrugged. She calls the opposing smirkers, “parasites”, “looters”, “moochers,” and my favorite: “do gooders.” It’s for the common good that the narcissist should fail, they claim.

Often these opponents have good reasons to oppose. The Ayatollah Khomeini had a vision similar to Disney: an Islamic Republic in Iran where everyone is happy being a devout Muslim of his stripe. The opponents feared, correctly, that everyone who was not happy would be flogged, hanged, or beheaded. I think it’s legitimate to not want to be forced to be devout. Similarly, with Genghis Khan, or Vladimir Putin. Putin compares himself to Peter the Great who expanded Russia and conquered Crimea. The opponents have legitimate fears of WWII and claim that Ukrainian independence is semi legit. Regarding Musk’s plans to colonize Mars, I note that Neil Armstrong and Gene Cernan have come out against it. There is no right or wrong here, but I have a soft spot for the visionaries, and a suspicion of the “smirkers” and “do gooders.”

Genghis Khan. He saw himself as a world changer. Some followed, some didn’t. Those who followed didn’t think he was crazy.

The smirkers and do-gooders include the most respectable people of today. They are thought leaders, who lose status if someone else exceeds them. They are surprised and offended by Martin Luther King’s dream, and Musk’s, Khomeini’s, Trump’s, and Lenin’s. Trump became president against formidable odds, and the smirkers said it was a fluke, he then lost, and they claimed it showed they were right. He may get a second term, though, and Musk may yet build a community on Mars. To the extent that the visionary succeeds, the smirkers claim it was easy; that they could have done the same, but faster and better. They then laud some fellow smirker, and point out aspects of the vision that failed. In any case, while the narcissist is definitely abnormal, it’s not a disease, IMHO. It’s what makes the world go round.

Rain barrels aren’t much good. Wood chips are better, And I’d avoid rain gardens, even as a neighbor.

1 Reply

A lot of cities push rain barrels as a way to save water and reduce flooding. Our water comes from the Detroit and returns to it as sewage, so I’m not sure there is any water saving, but there is a small cash saving (very small) if you buy 30 to 55 gallon barrels from the city and connect them to the end of your drain spout. The rainwater you collect won’t be pure enough to drink, or safe for bathing, but you can use it to water your lawn and garden. This sounds OK, even patriotic, until you do the math, or the plumbing, or until you consider the wood-chip alternative.

The barrels are not cheap, even when subsidized they cost about $100 each. Add to this the cost and difficulty of setting up the collection system and the distribution hose. Water from your rain barrel will not flow through a normal nozzle as there is hardly any pressure. Expect watering to take a lot longer than you are used to.

40 gallon rain barrels. Two of these give about 70 usable gallons every heavy rain fall. That’s about 70¢ worth.

In Michigan you can not leave the water in your barrel over the winter, the water will freeze and the barrel will crack. You have to drain the tank completely every fall, an almost impossible task, and the tank is attached to a rainspout and the last bit of water is hard to get out. Still, you have to do it, or the barrel will crack. And the savings for all this is minimal. During a rainy month, you don’t need this water. During a dry month, there is no water to use. Even at the best, the The marginal cost of water in our town is less than 1¢ per gallon. For all the work and cost to set up, two complete 40 gallon tanks (like those shown) will give you at most about 70 usable gallons. That’s to say, almost 70¢ per full filling.

How much lawn can you water? Assume you like to water your lawn to the equivalent of 1″ of rain per week, your 70 gallons will water about 154 ft2 of lawn or garden, virtually nothing compared to the typical Michigan 2000 ft2 lawn. You’ll still have to get most of your water from the city’s main. All that work, for so little benefit.

Young trees with chip volcanos, 1 ft high x18″. Spread the chips to the diameter of the leaves.You don’t need more than 2″.

A far better option is wood chips. They don’t cover a lawn, but they’re great for shrubs, trees or a garden. Wood chips are easy to spread, and they stop weeds and hold water. The photo at left shows a wood chips around the shrubs, and a particularly poor use of wood chips around the trees. For shrubs, trees, or a garden, I suggest you put down 1 to 2 inches of wood chips. Surround a young tree at that depth to the diameter of the branches. Do not build a “chip volcano,” as this lazy landscaper has done.

Consider that, covering 500 ft2 of area to a depth of 1.5 inches will take about 60 cubic feet of wood chips. That will cost about $35 dollars at the local Home Depot. This is enough to hold about 1.25″ or rainwater, That’s about 100 ft3 or water or 800 gallons. The chips prevent excess evaporation while preventing weeds and slowly releasing the water to your garden. You do no work. The chips take almost no work to spread, and will keep on working for years, with no fear of frost-damage. A as the chips stop working, they biocompost slowly into fertilizer. That’s a win.

There is a worst option too, called a rain garden. This is often pushed by environmental-gooders. You dig a hole near your downspout, perhaps ten feet in diameter, by two feet deep, and plant native grasses (weeds). When it rains, the hole fills with water creating a mini wetland that will soon smell like the swamp that it is. If you are not lucky, the water will find a way to leak into your basement. If that’s your problem look here. If you are luckier, your mini-swamp will become the home of mosquitos, frogs, and snakes. The plants will grow, then die, and rot, and look awful. It is very hard to maintain native grasses. That’s why people drain swamps and grow trees or turf or vegetables. If you want to see a well-maintained rain garden, they have two on the campus of Lawrence Tech. A wetland isn’t bad, but you want drainage, Make a bioswale or muir.

Dark matter: why our galaxy still has its arms

Leave a reply

Our galaxy may have two arms, or perhaps four. It was thought to be four until 2008, when it was reduced to two. Then, in 2015, it was expanded again to four arms, but recent research suggests it’s only two again. About 70% of galaxies have arms, easily counted from the outside, as in the picture below. Apparently it’s hard to get a good view from the inside.

Four armed, spiral galaxy, NGC 2008. There is a debate over whether our galaxy looks like this, or if there are only two arms. Over 70% of all galaxies are spiral galaxies. 

Logically speaking, we should not expect a galaxy to have arms at all. For a galaxy to have arms, it must rotate as a unit. Otherwise, even if the galaxy had arms when it formed, it would lose them by the time the outer rim rotated even once. As it happens we know the speed of rotation and age of galaxies; they’ve all rotated 10 to 50 times since they formed.

For stable rotation, the rotational acceleration must match the force of gravity and this should decrease with distances from the massive center. Thus, we’d expect that the stars should circle much faster the closer they are to the center of the galaxy. We see that Mercury circles the sun much faster than we do, and that we circle much faster than the outer planets. If stars circled the galactic core this way, any arm structure would be long gone. We see that the galactic arms are stable, and to explain it, we’ve proposed the existence of lots of unseen, dark matter. This matter has to have some peculiar properties, behaving as a light gas that doesn’t spin with the rest of the galaxy, or absorb light, or reflect. Some years ago, I came to believe that there was only one gas distribution that fit, and challenged folks to figure out the distribution.

The mass of the particles that made up this gas has to be very light, about 10-7 eV, about 2 x 1012 lighter than an electron, and very slippery. Some researchers had posited large, dark rocks, but I preferred to imagine a particle called the axion, and I expected it would be found soon. The particle mass had to be about this or it would shrink down to the center of he galaxy or start to spin, or fill the universe. Ina ny of these cases, galaxies would not be stable. The problem is, we’ve been looking for years, and not only have we not seen any particle like this. What’s more, continued work on the structure of matter suggests that no such particle should exist. At this point, galactic stability is a bigger mystery than it was 40 years ago.;

So how to explain galactic stability if there is no axion. One thought, from Mordechai Milgrom, is that gravity does not work as we thought. This is an annoying explanation: it involves a complex revision of General Relativity, a beautiful theory that seems to be generally valid. Another, more recent explanation is that the dark matter is regular matter that somehow became an entangled, super fluid despite the low density and relatively warm temperatures of interstellar space. This has been proposed by Justin Khoury, here. Either theory would explain the slipperiness, and the fact that the gas does not interact with light, but the details don’t quite work. For one, I’d still think that the entangled particle mass would have to be quite light; maybe a neutrino would fit (entangled neutrinos?). Super fluids don’t usually exist at space temperatures and pressures, and long distances (light years) should preclude entanglements, and neutrinos don’t seem to interact at all.

Sabine Hossenfelder suggests a combination of modified gravity and superfluidity. Some version of this might fit observations better, but doubles the amount of new physics required. Sabine does a good science video blog, BTW, with humor and less math. She doesn’t believe in Free will or religion, or entropy. By her, the Big Bang was caused by a mystery particle called an inflateon that creates mass and energy from nothing. She claims that the worst thing you can do in terms of resource depletion is have children, and seems to believe religious education is child abuse. Some of her views I agree with, with many, I do not. I think entropy is fundamental, and think people are good. Also, I see no advantage in saying “In the beginning an inflateon created the heavens and the earth”, but there you go. It’s not like I know what dark matter is any better than she does.

There are some 200 billion galaxies, generally with 100 billion stars. Our galaxy is about 150,000 light years across, 1.5 x 1018 km. It appears to behave, more or less, as a solid disk having rotated about 15 full turns since its formation, 10 billion years ago. The speed at the edge is thus about π x 1.5 x 1018 km/ 3 x 1016 s = 160km/s. That’s not relativistic, but is 16 times the speed of our fastest rockets. The vast majority of the mass of our galaxy would have to be dark matter, with relatively little between galaxies. Go figure.

Right to work is a right.

Leave a reply

In 26 states you can work in a unionized industry without joining a union. You can even cross a union strike line if you like. It’s called “right to work.” Michigan allowed it up till last month, but no longer. Immediately following the Democrats’ taking majority of the MI legislature, they voted to make non-union membership illegal. The claim was that those who do not want to be represented by the state-acknowledged union is misguided, or worse.

The argument for making union membership mandatory is presented in the poster at right. It notes that states that banned right to work are richer, with workers getting higher pay and benefits. These include California, New York, NJ, Washington, Alaska,.. See the map below. Although these states, on average have higher yearly wages, they also have higher taxes, higher costs of living, and more high-tech jobs. The cause and effect implied by this poster is erroneous, I think: The claim is that if you are forced to join a union you will be paid more with more benefits. I strongly suspect that the reality is that these states have high wages and high benefits and a lot of people working in safe fields, programming for example. They then force workers to work for one union so they’ll be easier managed, not because they want a strong opposition.

Another thing, even if you could guarantee higher wages by forced union membership, and you could avoid the high taxes and high cost of living that you find in NY and California, no person should be forced to accept representation by a group that they don’t get to choose, or who supports social goals that the worker doesn’t support. I don’t believe this is fair, or moral, but that’s how it is. It’s the law in most every state with a Democrat as governor and where Democrats control the legislature.

Right to work as of last month, before Michigan forced unionism.

Union membership had been declining in Michigan for years, but it took a particular nose dive in 2016 when the unions spent heavily for Clinton while blue collar workers supported Trump. It was 14% or workers before the law changed. Workers claimed that their unions were working against them, and complained about how their dues were spent. It also came out that some of the Michigan union bosses had stolen money from their funds to build fancy private houses — using non-union labor to do it. When the union bosses tried to show their muscle by calling strikes, the strikes accomplished little, or went on for months. The results were two-tier salaries, layoffs, and business failures. The working for the local newspapers teamsters struck, and one newspaper collapsed. The other chose non-union drivers. The teamsters are still on strike, 10 years later. I’d think a worker should be able to leave a union like this.

I’m a fan of unions, but think the worker should be able to choose. I’m a particular fan of craft unions that work to improve the quality of their work along with the quality of their workers lives. This helps everyone. I suspect that unions should not be able to support political parties too. See my thoughts on unions, here.

Michigan has a particularly strong history of crooked union bosses. When Jimmy Hoffa challenged the Teamster bosses over how the retirement fund was spent, he vanished. The union’s bosses seem to have had him killed. The last place where he was seen alive is an Andiamo Restaurant near my home. He was picked up by someone he knew, perhaps his nephew. No one’s talking and his remains were never found. In Michigan you used to be able to choose your union just as you chose your political club and your own lawyer, or you could choose none at all. Nowadays, the law says otherwise. Maybe you don’t like this law. Maybe you don’t like the union boss or how he’s spending. Maybe you’d like to visit with Jimmy Hoffa.

Robert Buxbaum May 19, 2023. Aside from everything else, you have a right to have a state that isn’t high-wage, high-tax, even if you could prove people were happier in such states. Freedom is a good, in and of itself.

Hydrogenation, how we’ve already entered the hydrogen economy

Leave a reply

The hydrogen economy is generally thought to come in some distant future, where your car (and perhaps your home) runs on hydrogen, and the hydrogen, presumably, is made by clean nuclear or renewable solar or wind power. This is understood to be better than the current state of things where your car runs on dirty gasoline, and your home runs on coal or gas, except when the sun is shining bright and the wind is blowing hard. Our homes and cars can not run on solar or wind alone, although solar cells have become quite cheap, because solar power is only available in the daytime, basically for 6 hours, from about 9AM to 3PM. Hydrogen has been proposed as a good way to store solar and wind energy that you can’t use, but it’s not easy to store hydrogen — or is it? I’d like to suggest that, to a decent extent, we already store green hydrogen and use it to run our trucks. We store this hydrogen in the form of Diesel fuel, so you don’t realize it’s hydrogen.

Much of the oil in the United States these days comes from tar sands and shale. It doesn’t flow well at room temperature, and is too heavy and gooey for normal use. We could distill this crude oil and use only the light parts, but that would involve throwing away a huge majority of the oil. Instead we steam reform it to gasoline, ethylene and other products. The reaction is something like this, presuming an input feed of naphtha, C10H8:

C10H8 + 2 H2O –> C7H8 + C2H4 + CO2.

The C2H4 component is ethylene. We use it to make plastics. The C7H8 is called toluene. It is a component of high octane gasoline (octane rating about 114). The inventor of the process, Eugene Jules Houdry claimed to have won WWII for the allies because his secret process (Houdryflow catalytic cracking) allowed high production of lots of gasoline of very high octane, giving US and British planes and trucks higher mpg than the Germans or Japanese had. It was a great money maker, but companies can make even more by adding hydrogen.

Over the last 2-3 decades, refineries have been adding catalytic hydrogenation processes. These convert high octane aromatic products, like toluene to low -octane diesel and jet fuel. These products sell for more. Aromatic toluene is exposed to hydrogen at about 500°C and 300 psi (20 bar) to produce heptane, an excellent diesel fuel with about 7% more energy content than toluene per gallon.

C7H8 + 4H2 –> C7H16.

Diesel fuel sell for about 20% more than gasoline per gallon, in part because of the higher energy content, and because Diesel engines are more efficient than gas engines. What’s more, toluene expands as it’s converted to heptane. One gallon of toluene converts to 1.16 gallons of heptane. As a result hydrogenation adds about 40% to the sales price per molecule. Refineries have found that they can make significant money this way if they can buy cheap hydrogen. Over the last few years, several refineries in Norway and Texas (high sun and wind areas) have added hydrogenators along with electrolysis units to produce the cheap hydrogen when no one needs the unwanted electricity generated when supply exceeds demand. Here is an analysis of the thermodynamics of this type of hydrogen generation.

Canada’s doctor-assisted suicide killed 10,064 in 2021

Leave a reply

Canada’s healthcare is free to the user. It’s paid for by taxes, and it includes a benefit you can’t get in the US: free, doctor assisted suicide, euthanasia. This is a controversial benefit, forbidden in the Hippocratic oath because it’s close to murder, and includes the strong possibility of misuse of trust. Assistance by a trusted professional can be a bit likes coercion, and that starts to look like murder — especially since the professional often has a financial incentive to see you off.

From Charlie Hebdot (a French, humor magazine): The medical association refuses to participate in euthanasia — Why? People are already dining quite well on their own waiting in the emergency room.

In 2021, according to Statistics Canada, Canada assisted the suicide of 10,064 people, 3.3% of all Canadian deaths. There were about 4,000 more, non-assisted suicides. In Quebec, the Canadian Provence where Medical Assistance in Dying (MAiD) is most popular, 5.1% of deaths result from MAID. The Netherlands has a similar program that results in 4.8% of deaths. In Belgium, it’s 2.3%. These countries’ suicide rates are far higher than in the US, and account for far more deaths, per capita than from guns in the US. My guess is that suicide is common because it is free and professional. It’s called “Dignity in Dying,” in Europe, a title that suggests that old folks who don’t die this way are undignified.

In Canada, about 80% of those who requested MAiD were approved. A lot of the remainder were folks who died or changed their mind before receiving the fatal dose. If you attempt suicide on your own, it’s likely you won’t succeed, and you may not try again. With doctor assisted suicide, you’re sure to succeed (even if you change your mind after you get your lethal shot?)

In Canada you don’t have to be terminally ill to get MAiD, you just have to be in pain, and extreme psychological pain counts. Beginning March 17, 2024, depression will be added as a legitimate reason. According to Canadian TV news, depressives are lining up (read some interviews here). Belgium and Netherlands allows elders to be euthanized for dementia, and children to be euthanized on the recommendation of their parents. France passed similar legislation, but the doctors refused to go along, see cartoon. I applaud the French doctors.

Rodger Foley says he’s being pressured to ask for medical suicide, picture from the NY Post

There have been persistent claims that Canadian doctors and nurses push assisted suicide on poor patients, telling them how much bother they are and how much resources they are using. There has been an outcry in British and American newspapers, e.g. here in the Guardian, and in the NY Post, but not in Canada, so far. Rodger Foley, a patient interviewed by the NY Post, recorded conversations where his doctors and nurses put financial pressure on him. “They asked if I want an assisted death. I don’t. I was told that I would be charged $1,800 per day [for hospital care]. “I have $2 million worth of bills. Nurses here told me that I should end my life.” He claims they went so far as to send a collection agency to further pressure him. In another case, a disabled Canadian veteran asked for a wheelchair ramp, and was told to apply for MAiD.

Even without outside pressure, many people seeking MAiD often cite financial need as part of the reason. A 40 year old writer interviewed by Canadian television said that he can’t work and lives in poverty on a disability payment of just under $1,200 a month. “You know what your life is worth to you. And mine is worthless.”

The center of the argument is the value of a person in a social healthcare state when their economic value is less than the cost of keeping them alive. Here, Sabine Hossenfelder, an excellent physicist, argues that the best thing one could do for global warm and to preserve resources is to have fewer people. Elon Musk says otherwise, but Ms Hossenfelder claims this only shows he is particularly unworthy. There’s a Germanic logic here that gave us forced euthanasia in the 1940s.

I find euthanasia abhorrent, especially when it’s forced on children, the elderly, and depressed folks. I also reject the scary view of global warming, that it is the death of the earth. I’ve argued that a warm earth is good, and that a cold earth is bad. Also, that people are good, that they are the reason for the world, not its misfortune. It seems to me that, if suicide aid must be provided, state-funded hospitals should not provide it. They have a financial incentive to drop non-paying, annoying patients. That seems to be happening in Canada. A patient must be able to trust his or her doctor, and that requires a belief that the doctor’s advice is for his or her good. Unfortunately, Canadian politicians have decided otherwise. I say hurray for the doctors of France for not going along.

Robert Buxbaum, April 25, 2023. The medical profession is shady even when you pay for services, see Elvis Presley’s prescription. There’s always a financial interest. Even based on old data, the US is not a particularly high-murder country if suicide is considered murder.
