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.

Schematic of the hydrocracking process, from the US energy information agency

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.

China won’t invade Taiwan, perhaps Vietnam

1 Reply

For 2000 years Chinese rulers have either fixed the problems caused by their predecessors, or become the absolute ruler who brings new problems and a war. Eighteen times over the last 2000 years, the absolute ruler has chosen is to invade Vietnam. Chairman Xi Jinping took full power over China five years ago, and as I predicted then, purged the party of all other competent leaders, including his predecessor, Hu. He now has to do something, and that’s typically a war. Xi talks like he’d like to invade Taiwan, but I believe he’ll invade Vietnam instead, as so many others did before him. Taiwan (Formosa) is separated from mainland China by 100 miles of open sea. There’s been only two successful, modern invasions; by the Qing Chinese in 1683 with the help of the Dutch fleet, and in 1895 by Japan against the 5 month old Republic of Taiwan. Vietnam is much easer to invade: you just have to walk in.

Chiang KaiShek with Roosevelt and Churchill. He took power after WWII.Taiwan is now a Republic

Here’s my brief summary of 60 years of cyclical Chinese history: In the last decade of his life, 1966-76, Mao Zedung brought a horrible cultural revolution, killing 100 million or so by violence and famine, targeting anyone who might disagree with him. He was followed by Hua Kuofeng, Hu Yaobang, and Zhao Ziyang. They removed “the Gang of Four” and brought reform, toleration, and some rapprochement with the west. Hu also returned some autonomy to Tibet. Deng Xiaoping followed, put Zhao under house arrest, removed Hua and Hu (only recently buried), absorbed Tibet, invaded Vietnam, instituted a brutal on-child policy with, forced abortions and sterilizations, and put down the Tiananmen uprising 1989 -an uprising caused by the removal of Hu. Deng was followed by Jiang Zemin and Hu Jintao who exited Vietnam, lightened the one-child policy, and brought back some measure of freedom. This lead to Xi Jinping who appears to be in the mold of Mao and Deng. He’s removed Hu publicly during a communist party meeting, has taken absolute control, arrested China’s business innovators, and (likely) caused a pandemic by unsafe research at the Wuhan bio-research facility. His response to the pandemic is worthy of Mao: he welded people into their homes. Xi now needs a war to unify the country, and talks like he’ll invade Taiwan. Xi might do it; he has increased military spending by 2.5 times, to double that of the EU (equal to US spending). His army is likely to be used somewhere soon. But where?

At first glance, it makes some sense to think he’ll invade Taiwan. He has the same justification as Deng had for Vietnam, “to punish the wayward province.” Taiwan is small, 23 million people, and very rich (GDP = $1.3T, 10-15% of China). It’s especially rich in high-tech areas that Xi seems to want, and China ruled the island (Formosa) for 212 years between 1683 and its brief independence in 1895. I expect that Xi will invade Vietnam though, for many of the same reasons that Deng did: it’s easier, and the invasion won’t destroy US trade. Vietnam will not be super easy to conquer, of course, Putin’s invasion of Ukraine looks like it will go on for years, but Xi has 100 million men of military age. Driving these men into Vietnam is a lot easier than an amphibious invasion. Vietnam now, as then, has few friends -perhaps only India -while Taiwan has many (The US and Japan, primarily), and they have naval breakwaters that would make an amphibious landing difficult. Vietnam is only about half as rich as Taiwan (GDP = $650 B), but it has two things China needs more than technology: oil and food.

The Japanese invasion of independent Taiwan, The Republic of Formosa, in 1895. It took 5 months despite lopsided advantages. Plus 7 years to pacify the population.

Japan’s invasion of the Republic of Formosa in 1895 would have to be the model for a Chinese invasion today, assuming that’s the route Xi would take. Japan used a small force of 20,000 highly trained men, and a surprise landing at two sites. The formosan army of 75,000 was hardly armed, but it still took the Japanese 5 months to defeat them. It took another 7 years to pacify the population. Taiwan today is a lot better prepared than it was, with modern missiles and drones, a well-trained army of 500,000, and an active navy. Japan, Philippines, and the US would likely try to resupply Taiwan, and would have to be blockaded to prevent delivery. This is not so easy, since the nearest Japanese island is closer to Taiwan than Taiwan is to mainland China, and the Philippines is not far either. Then there are the sanctions that would follow an invasion of Taiwan, but not an invasion of Vietnam: the freezing of assets and the closing of markets. Susch sanctions have been tough on Russia but they would be devastating to China since China imports most of its oil and half of its food, much of it by sea. Whatever Xi gets from invading Taiwan will not match these losses, and I think Xi know it.

China’s new military bases are located around Vietnam, not around Taiwan

I suspect that Xi has already concluded that Vietnam is the smart place to invade. Supporting this view is a look at his preparations. Xi has not built the landing fleet that he’d need for Taiwan, but has instead militarized Hainan Island, plus four other, newly constructed, illegal islands in the South China Sea. These islands surround Vietnam, and are well suited to cut off the country from western aid. They are too far south to be effective in an action against Taiwan. You can tell a lot about what a person will do from what he has done, and what Xi has done is to prepare for an invasion of Vietnam.

Of walking sticks, canes, scepters, and wands.

Franklin’s walking stick, willed to General Washington. Now in the Smithsonian.

Many famous people carried walking sticks Washington, Churchill, Moses, Dali. Until quite recently, it was “a thing”. Benjamin Franklin willed one, now in the Smithsonian, to George Washington, to act as a sort of scepter: “My fine crab-tree walking stick, with a gold head curiously wrought in the form of the cap of liberty, I give to my friend, and the friend of mankind, General Washington. If it were a Scepter, he has merited it, and would become it. It was a present to me from that excellent woman, Madame de Forbach, the dowager Duchess of Deux-Ponts”. A peculiarity of this particular stick is that the stick is uncommonly tall, 46 1/2″. This is too tall for casual, walking use, and it’s too fancy to use as a hiking stick. Franklin himself, used a more-normal size walking stick, 36 3/8″ tall, currently in the collection of the NY Historical Society. Washington too seems to have favored a stick of more normal length.

Washington with walking stick

Walking sticks project a sort of elegance, as well as providing personal protection. Shown below is President Andrew Jackson defending himself against an assassin using his walking stick to beat off an assassin. He went on to give souvenir walking sticks to friends and political supporters. Sticks remained a common political gift for 100 years, at least through the election of Calvin Coolidge.

Andrew Jackson defends himself.

I started making walking sticks a few years back, originally for my own use, and then for others when I noticed that many folks who needed canes didn’t carry them. It was vanity, as best I could tell: the normal, “old age” cane is relatively short, about 32″. Walking with it makes you bend over; you look old and decrepit. Some of the folks who needed canes, carried hiking sticks, I noticed, about 48″. These are too tall to provide any significant support, as the only way to grasp one was from the side. Some of my canes are shown below. They are about 36″ tall, typically with a 2″ wooden ball as a head. They look good, you stand straight, and they provides support and balance when going down stairs.

Some of my walking sticks.

I typically make my sticks of American Beech, a wood of light weight, with good strength, and a high elastic modulus of elasticity, about 1.85 x106 psi. Oak, hickory, and ash are good options, but they are denser, and thus more suited to self-defense. Wood is better than metal for many applications, IMHO, as I’ve discussed elsewhere. The mathematician Euler showed the the effective strength of a walking stick does not depend on the compressive strength but rather on elastic constant via “the Euler buckling equation”, one of many tremendously useful equations developed by Leonhard Euler (1707-1783).

For a cylindrical stick, the maximum force supported by a stick is: F = π3Er4/4L2, where F is the force, r is the radius, L is the length, and E is the elastic modulus. I typically pick a diameter of 3/4″ or 7/8″, and fit the length to the customer. For a 36″ beech stick, the buckling strength is calculated to be 221 or 409 pounds respectively. I add a rubber bottom to make it non–scuff and less slip-prone. I sometimes add a rope thong, too. Here is a video of Fred Astaire dancing with this style of stick. It’s called “a pin stick”, in case you are interested because it looks like a giant pin.

Country Irishmen are sometimes depicted with a heavy walking stick called a Shillelagh. It’s used for heavier self-defense than available with a pin-stick, and is generally seen being used as a cudgel. There are Japanese versions of self defense using a lighter, 36″ stick, called a Han-bo, as shown here. There is also the wand, as seen for example in Harry Potter. It focuses magical power. Similar to this is Moses’s staff that he used in front of Pharaoh, a combination wand and hiking stick as it’s typically pictured. It might have been repurposed for the snake-on-a-stick that protects against dark forces. Dancing with a stick, Astaire style, can drive away emotional forces, while the more normal use is elegance, and avoiding slips.

Britons did better than Germans since Brexit

Leave a reply

Britain and Germany are the two largest economies in Europe. When Britain voted to leave the EU seven years ago, 23 June 2016, economists, royals, and the richer, smarter set predicted disaster. The unemployment rate at the time was 5.2% in the UK; economists guaranteed it would rise with Brexit due to the loss of access to the common market. Unemployment fell to 3.7% today: Embarrassing for economists, a bonus for British workers. Germany unemployment today is 5.6%, basically slightly higher than the 4.3% of 2016. There has been a large influx of Ukrainians into both countries, and of illegal boat people into the UK. These are people coming to get jobs, seeking a better life than available in the rest of the EU. That boat people don’t go the other way suggests that things are better in the UK.

Fromm Bloomberg, October 2022. See full article here. UK unemployment is down to 2.5% in February 2023.

Britain’s GDP was supposed to suffer from Brexit, too. Instead, GDP has grown by 18% since 2016, about 2.5% per year on average, outpacing Germany’s 10.6% total growth, 1.5% per year. Between 2016 and 2022, the British GDP rose to $3.19T from $2.7 T. Germany’s GDP increased to $3.57T, from $3.14T (data from the world bank). Separating from the EU helped, it seems and helped us too something Trump promoted. Germany chose close ties to Russia instead. That does not seem to be a big plus.

German Inflation has traditionally been low. It has increased in the past few months due to rising food and energy costs.

Inflation is higher in the UK than in Germany, 10.4% as of February 2023 versus 8.7% in Germany, or 9.9% in the European Union and a whole. I don’t think that’s Brexit. The UK typically has seen higher inflation rate than Germany, something seen by the steady drop of the pound. They have a tradition of inefficiency and silliness. Part of the problem today is that Britain gets much of its electricity from natural gas, while the French use nuclear power. Nuclear is cheap and clean, compared to natural gas. Coal is cheap and dirty; China uses it extensively and plans to use more. But the real cause of the UK’s higher inflation is inherent in the British and Germans, IMHO. The Germans hate inflation, the Brits don’t mind.

Population growth (green) or decline (orange) in Europe

For high-power, white collar workers, Britain seems to be as good a spot as Germany, maybe better. Maximum tax rates are slightly lower than in Germany (45% vs 47.45%), and the population is growing (slowly). Apparently, people like it enough to come there and have children; children are a good sign, IMHO. It’s harder to get good workers, but population growth suggests that the problems won’t be catastrophic (as they were in Japan, and likely will be in Germany). If you want a developed economy with yet-lower taxes, plus good workers, the US is the place to be, IMHO. Our maximum tax rate is 37%. You get fewer free services (healthcare), but you can earn enough to afford it. Prince Harry moved to the US recently, joining foot-baller David Beckham, and Pele a few years back. Former Python, John Cleese, came here too… They complain that Americans are cheap when it comes to helping others (but that’s out attraction). They claim that we’re violent and crass (true enough!) but say that the UK isn’t what it was. The fact that refugees seem to prefer the UK to Germany, suggests that Britain is a place to go. Britain, I’d say seems to have come out pretty well from Brexit.
