Hockey sticks have gotten bendier in recent years, with an extreme example shown below: Alex Ovechkin getting about 3″ of bend using a 100# stiffness stick. Bending the stick allows a player to get more power out of wrist shots by increasing the throw distance of the puck. There is also some speed advantage to the spring energy stored in the stick — quite a lot in Mr Ovechkin’s case.
Alexander Ovechkin takes a wrist shot using a bendy stick.
A 100# stiffness stick takes 100 pounds of force in the middle to get 1″ of bend. That Ovechkin gets 3″ of bend with his 100# stick suggests that he shoots with some 300 lbs of force, an insane amount IMHO. Most players use a lot less force, but even so a bendy stick should help them score goals.
There is something that bothers me about the design of Alex Ovechkin’s stick though, something that I think I could improve. You’ll notice that the upper half of his stick bends as much as the lower half. This upper-bend does not help the shot, and it takes work-energy. The energy in that half of the bend is wasted energy, and its release might even hurt the shooter by putting sudden spring-stress on his wrist. To correct for this, I designed my own stick, shown below, with an aim to have no (or minimal) upper bend. The modification involved starting with a very bendy stick, then covering most of the upper half with fiberglass cloth.
I got ahold of a junior stick, 56″ long with 60# flex, and added a 6″ extension to the top. Doing this made the stick longer, 62″ long (adult length) and even more bendy. One 1″ of flex requires less force on a longer stick. I estimate that, by lengthening the stick, I reduced it to about 44#. Flex is inversely proportional to length cubed. I then sanded the upper part of the stick, and wrapped 6 oz” fiberglass cloth (6 oz) 2-3 wraps around the upper part as shown, holding it tight with tape at top and bottom when I was done. I then applied epoxy squeezing it through the cloth so that the composite was nearly transparent, and so the epoxy filled the holes. This added about 15g, about 1/2 oz to the weight. Transparency suggested that the epoxy had penetrated the cloth and bonded to the stick below, though the lack of total transparency suggests that the bond could have been better with a less viscous epoxy. Once the epoxy had mostly set, I took the tape off, and stripped the excess fiberglass so that the result looked more professional. I left 23″ of fiberglass wrap as shown. The fiberglass looks like hockey tape.
Assuming I did the gluing right, this hockey stick should have almost all of the spring below the shooter’s lower hand. I have not measured the flex, but my target was about 80 lbs, with improved durability and the new lower center of bend. In theory, more energy should get into the puck. It’s a gift for my son, and we’ll see how it works in a month or so.
I’ve gone sailing a few times this summer, and once again was struck by the great difference between sailing and boating, as well as by the mystery of the hull speed.
Sailors are distinct from boaters in that they power their boats by sails in the wind. Sailing turns out to be a fairly pleasant way to spend an afternoon. At least as I did it, it was social, pleasant, and not much work, but the speeds were depressingly slow. I went on two boats (neither were my own), each roughly 20 feet long, with winds running about 10-15 knots (about 13 mph). We travelled at about 3 knots, about 3.5 mph. That’s walking speed. At that speed it would take about 7 hours to cross Lake St. Clair (25 miles wide). To go across and back would take a full day.
Based on the length of the boats, they should have been able to go a lot faster, at about 5.8 knots (6 mph). This target speed is called the hull speed; it’s the speed where the wave caused by the bow provides a resonance at the back of the boat giving it a slight surfing action, see drawing.
This speed can be calculated from the relationship between wave speed and wavelength, so that Vhull = √gλ/2π where g is the gravitational constant and λ is the water line length of the boat. For Vhull in knots, it’s calculated as the square-root of the length in feet, multiplied by 1.34. For a 20 foot boat, then,
While power boats routinely go much faster than this, as do racing skulls and Americas cup sailboats, most normal sailboats are designed for this speed. One advantage is that it leads to a relatively comfortable ride. There is just enough ballast and sail so that the boat runs out of wind at this speed while tipping no more than 15°. Sailors claim there is a big increase in drag at this speed, but a look at the drag profile of some ocean kayaks (12 to 18 feet, see below) shows only a very slight increase around this magical speed. More important is weight; the lowest drag in the figure below is found for the shortest kyack that is also the lightest. I suspect that the sailboats I was on could have gone at 6 knots or faster, even with our current wind, if we’d unrolled the spinnaker, and used a ‘screecher’ (a very large jib), and hung over the edge to keep the boat upright. But the owner chose to travel in relative comfort, and the result is that we had a pleasant afternoon going nowhere.
Data from Vaclav Stejskal of “oneoceankyacks.com”
And this brings me to my problem with power boating. Th boats are about the same length as the sailboats I was in, and the weight is similar too. You travel a lot faster, 20 to 25 knots, and you get somewhere, but the boats smell, and provide a jarring ride, and I felt they burn gas too fast for my comfort. The boats exceed hull speed and hydroplane, somewhat. That is, they ride up one wave, fly a bit, and crash down the other side, sending annoying wakes to the sailboaters. We crossed lake St. Clair and rode a way down the Detroit river. This was nice, but it left me thinking there was room for power -assisted sailing at an intermediate speed, power sailing.
Both sailboats I was on had outboard motors, 3 hp, as it happened, and both moved nicely at 1 hp into and out of the harbor, even without the sail up. Some simple calculations suggest that, with I could power a 15 to 20 foot sailboat or canoe at a decent speed – hull speed – by use of a small sail and an electric motor drawing less than 1 hp, ~400 W, powered by one or two car batteries.
Consider the drag for the largest, heaviest kayak in the chart a move, the Cape Ann Double, going at 6.5 knots. At 6 knots, the resistance is seen to be 15 lbs. To calculate the power demand, convert this speed to 10 fps and multiply by the force:
Power for 6 knot cruising = 10 fps x 15 lbs = 150 ft lbs/s = 202 W or 0.27 hp.
Outboard motors are not 100% efficient, so let’s assume that you need to draw more like 250 W at the motor, and you will need to add power by a sail. How big a battery is needed for the 250 W? I’ll aim for powering a 4 hour trip, and find the battery size by multiplying the 250 W by 4 hours: that’s 1250 Hrs, or 1.25 kWh. A regular, lithium car battery is all that’s needed. In terms of the sail, I’m inclined to get really invovative, and use a Flettner sail, as discussed here.
It seems to me that adding this would be a really fun way to sail. I’d expect to be able to go somewhere, without the smell, or the cost, or being jarred to badly. Now, all I need is a good outboard motor, and a willing companion to try this with.
It gets so little notice from the news agencies that many will be surprised to find that China has a space station. It’s known alternately as the Tiangong Space Station or the CSS, Chinese Space Station; it’s smaller than the International Space Station, ISS, but it’s not small. Here is a visual and data comparison, both from Wikipedia.
China’s space station is smaller than the ISS, but just about as capable. Cooperation leads to messiness (and peace?)
The ISS has far more solar panels, but the power input is similar because the CSS panels are of higher efficiency. As shown in the table below, the mass of the ISS is about 4.5 times that of CSS but the habitable volume is only 3 times greater than of CSS, and the claimed crew size is similar, of 3 to 6 compared to 7. The CSS is less messy, less noisy, with less mass, and more energy efficiency. Part of the efficiency comes from that the CSS uses ion propulsion thrusters to keep the station in orbit, while the ISS uses chemical rockets. The CSS thus seems better, on paper. To some extent that’s because it’s more modern.
Another reason that the ISS is more messy is that it’s a collaboration. A major part of its mission is to develop peaceful cooperation between the US, Europe and Russia. It’s been fairly successful at this, especially in the first two decades, and part of making sure parts from The US, Russia, Europe, Japan, and Canada all work together is that many different standards must be tolerated and connected. The ISS tolerates different space suits, different capsules, different connections, and different voltages. The result is researchers communicate, and work together on science, sending joint messages of peace to the folks on earth. Peace is an intended product.
By contrast, the Chinese space station is solely Chinese. There are no interconnection issues, but also no peace dividend. It has a partially military purpose too, including operation of killer satellites, and some degree of data mining. This was banned for ISS. So far the CSS has hosted Chinese astronauts. No Chinese astronauts have visited the ISS, either.
Long march 6A rocket set to supply the CSS. It is very similar to the Delta IV.
India was asked to join the ISS, but has declined, wishing to follow China’s path of space independence. The Indian Space Research Organization plans to launch a small space station on its own, Gaganyaan, in 2025, and after that, a larger version. That’s a shame, though it’s not clear how long cooperation will continue on the ISS, either. See the movie I.S.S. (2023) for how this might play out. Currently, there is a tradition of cooperation about ISS, and it’s held despite the War in Ukraine. The various nations manage to work together in space and on the ground, launching people and materials to the ISS, and working together reliability.
Although it isn’t a direct part of the space stations, I should mention the troubles of the Boeing Star-liner capsule that took two astronauts to the ISS compared to the apparently flawless record of the CSS. The fact is, I’m not bothered by failures, so long as we learn from them. I suspect Boeing will learn, and suspect that this and other flailing projects would be in worse shape without the ISS. Besides, the ISS has been a major catalyst in the development of SpaceX, a US success story that China seems intent on trying to copy. SpaceX was originally funded, at low level, to serve as a backup to Boeing, but managed to bypass them. They now provide cheaper, more reliable travel through use of reusable boosters. The program supplying CSS uses traditional, disposable rockets, the Long March 5 and 6 and 7. These resemble the Atlas V, Delta IV and Delta IV Heavy. They appear to be reliable, but I suspect they are costly too. China is currently developing a series of reusable rocket systems. The Long March 9, for example will have the same lift capacity as SapceX’s Starship, we’re told. Will the Indian program choose this rocket to lift their space station, or will they choose SpaceX, or something else? The advantages of a reusable product mostly show up when you get to reuse it, IMHO.
Among the wonders of the western world is how many people are allergic to nuts compared to a few decades ago, and to gluten, and to a host of other things that hardly anyone was allergic to 50 years ago. Perhaps it’s a change in perception, but it doesn’t seem that way.
When I was in public school in NY, back in the 1960s, there was a subsidized lunch program serving, every day, peanut butter sandwiches. Peanut butter is nearly totally fat. It was ladled each day, from a giant tub, provided by the USDA, and slathered on USDA bread along with jelly from some other vat. The smell filled the lunch area, and the fats and sugars filled our stomaches. No one seemed bothered by the nuts, and no one showed obvious signs of passing out. And despite the ill diet, we were less obeease than today. Even today, in poor countries, thy still serve massive peanut butter dishes, or bread covered in lard, and these countries show fewer allergy problems, and less obesity in general.
Perhaps it is the lack of exposure to peanuts in the US that caused the allergy (sounds almost plausible), and maybe it’s the dietetic food that causes obesity, and the glut of non-gluten that causes gluten allergies. These connections may be false, but If true, it would suggest we’re in for many more problems.
Moving to depression and dementia. We’re seeing more and more of both, and at earlier ages. In our era, virtually everyone over 80 shows signs of clinical dementia, often Alzheimer’s dementia, but the rates are rising, especially in those 55-70, and it seems most every adult is depressed. I don’t know why, though lots of people on the internet have speculative explanations. There are also cures, and perhaps some work. The research behind at least one of the best hopes for an Alzheimers cure was shown to be falsified, just made up. Not that funding was stopped quite, highlighting another problem that is becoming more common: people in trust positions no longer behave in a trustworthy way. Nor are they punished for lying. Strange to add that an anti-obesity drug, Metformin, seems to actually work at weight loss, and helps against Alzheimers dementia. Then again, from other research, it seems that obesity protects from dementia.
Some of the problem seems to be societal, a lack of friendship and companionship. I could imagine that isolation leads to dementia, depression, and weight gain. Another thought, pushed by RFK Jr., is that new drugs and vaccines are responsible for allergies and ADHD, along with changes in diet. It’s possible. At least some comes from early diagnosis, and a change in the definition of dementia. Perhaps that’s the reason for the significant difference state to state. Yesterday’s curmudgeon is redefined as depressed, and drugged (more in some states than others), and becomes isolated (again more in some communities). The disoriented, lonely patient is then given anti anxiety drugs and classified as a dementia patient. It happens in some cases, but there seems to be a rise in real dementia too: the sort of stumbling and blankness that reflects general brain deterioration. As for ADHD, I’m still not convinced this is a new real disease; it could be that’s how boys always behaved.
Would we be less depressed or demented or less autistic with different vaccinations, or different foods, or with more human interaction? Would people be less isolated if they were less depressed or autistic? RFK’s family now claims that RFK Jr is demented himself for even asking these questions. My guess, totally unsupported is that the rise in allergies, dementia, obesity, and depression are related somehow, but I’m not convinced that RFK Jr. has picked out the right connection. What causes what? Perhaps someone can use statistics, or biology experiments to help untangle this stuff. It seems horribly important to the majority of Americans.
Robert Buxbaum, Sept 10, 2024. There was a. bit of a joke in the last comments: my daughter got a degree in epidemiology, and is employed in part to answer just the sort of questions I’ve posed.
Few people learn cursive these days with any skill or speed. It’s a shame. This is a form of traditional art and communication. Handwriting is a slower way of writing, that leads to a different type of letter or essay. The sentences are, typically longer, and the words more expressive because the experience of writing and reading cursive is more expressive than with text. The emotional state and energy of the writer comes through the cursive writing, because the writing itself is a form of creative art, adding to the words.
Send a letter or a post card, and you’ve sent a work of art. You’ve communicated words, or course, but far more than with a text or email. First off, there is the picture on the card. You bought that card, or took the picture. Then there is the art of how many words you use. Each letter is directed to only one person, not to 100 as with a text. As a result, people will keep your letter or card far more than they will not keep a text an email. It is more from you, and more to them. You are likely to put more (or different) things in: experiences and feelings that don’t go into an email or text-letter. The size of your writing communicates and even your cross-outs are part of a cursive communication. With email or text, there are no natural cross outs, and you can send the same letter to 100 people, so you write more blandly, with an eye for eventual reuse for someone else. A cursive note is intended for only one person, the one recipient, and this affects both the words, and the form of the words.
Cursive also lends itself to adding a small sketch or doodle. This becomes part of a personal part of the art in a way that does not fit with normal text. It’s calligraphy and conceptional art, an important part of education, and a continuation of western culture. In normal texts, some people have come to add emojis or GIFs, but these are nowhere near as personal or expressive. The cursive letter or note is personal and spicy. It’s an important art form, at least a valid an art form as any that could be taught in school, and it should be.
Robert E. Buxbaum, Sept 1, 2024. I’m running for school board, and like the idea of teaching basic knowledge as a foundation of creativity. One of these basics, I think, is cursive writing.
It’s hard to notice the lack of something, but there’s been a sharp drop-off in the the number of serial killers. Nearly gone are folks like John Wayne Gacy (the clown killer), Jeffrey Dahmer (severed heads, cannibalism, necrophilia), Gary Ridgway, “The Green River Killer” (71 prostitutes killed). Mostly, they were sexual sadists, men who’d have sex with strangers (able or female) and then kill them. In 1987, there were 198 active in the US and many more inactive; by 2018 it was down to 12. And these few are less-prolific, and less-colorful, like Anthony Robinson, “the shopping cart killer”, who killed 4-6 in DC, transporting the bodies in shopping carts.
It’s not clear why there are so few these days. Perhaps it’s the prevalence of surveillance cameras, or improvements in DNA and other pic technology. But these explanations don’t explain why there were so few before 1960. There were some mass murderers, “Jack the Ripper,” “the Boston Strangler” but few before 1960.
Police like to credit the drop off to their detective skills, but there are still plenty of violent crimes that go unsolved, about half the murders in Detroit for example, or most of the rapes in Europe. I suspect that serial killing spiked up in the 60s because of a spike in friendliness, and spiked down in the 2000s because it ended. Before the hippy era, people were cautious of gangsters, rapists, homosexuals, and spies under the bed. But that changed in the 60s. Folks thought it was cool to hitchhike, or pick up random guys. Now, we’re back to being cautious.
A personal story: I was visiting Toronto in the late 1980s and someone I didn’t know overheard that I was planning to drive back to Detroit that afternoon. He asked if I would not mind driving his teenaged daughters to Detroit to see their grandmother, and I said “yes.” At the border, the guards asked who these girls were, and I said I didn’t know. I hadn’t asked. The border guards let us through without passports after a call to the grandmother. I would not be as ready to offer a ride today, and the parents would not be as trusting, nor would the guards.
Serial killings are down since 1990, but mass shootings are up.
Despite much the stricter gun laws, there’s been a rise in crime and a steady growth in the number of murderers in our major cities. There’s also been a rise in synagogue attacks, and a rise in mass murders. These folks kill many in one day or as part of gang-drug activity. Stricter gun laws seem to have made things worse, not better. They do not stop the killers and they hamper the defenders. I took a look at synagogue attacks, and find a pistol would have helped.
On a societal level, I think it would help to have fewer illegal aliens, or aliens who enter with no positive record or skills. It would help to have psychological treatment and lockup for crazy folks and prisoners. Currently, we send violent crazy folks out on the streets until they do something true horrific. More consistent prison sentences are needed for criminals too. We’ now’ve come to use the courts for political theater: Biden’s son should not go to jail for years because he lied on a gun purchase, nor should Trump get for putting down a prostitute as “legal fees”. Nor is his half-billion dollar fine appropriate. Minor crime deserves minor punishment. As a result of our crazy courts, violent criminals are let go as with the MSU killings near me. He was a crazy violent black man, and there was no way, in the law to give him a short sentence, or counseling, or job training. When our incarcerated leave prison, they have anger, plus no jobs or skills. Don’t be surprised when these folks turn to violent crime.
When the UK left the EU, they gained some economic freedom, but lost easy access to their largest trade partner. They avoided having to follow the weird green policies of the EU, and no longer had to take low cost workers from Poland, Bulgaria, Tec, but having lost easy access to European trade, the assumption was that they would want a trade deal soon, with someone, and the likely someone was the USA.
At first things went pretty well. there was the predicted crash didn’t come, showing that the top economists were talking out their hats, or trying to scare people to stay in the EU. And then Trump proposed the first of four attempts at a trade deal, and things got ugly. All four attempts were rejected in a most-forceful and insulting way.
When Trumps first forays at a trade deal were rejected, he attempt a visit in the summer of 2017. The British Parliament forbidding the visit, accepting it only by a slim majority with the PM, May making no strong case. The mayor of London protested with a blimp of Trump as a big baby, and the Queen was not sure she had time for tea (she had time for Obama). Trump cancelled the visit, and May made deals with Norway, Switzerland, Israel, Palestine, and Iceland. Why these but not the US?
Over the next two years Trump made trade deals with Mexico, Canada, Japan, and Korea, trying The UK again in July, 2019. This time, Theresa May was more welcoming — she was facing an election — but the blimp was brought out again, and allowed to follow Trump around England, along with a statue of Trump on the toilet, tweeting, and making fart sounds while saying “witch hunt,” “no collusion*”, and other comic comments. All rather insulting, and deal with the UK was signed.
I suspect Trump’s offers to the UK were similar to those with Japan, and Japan seemed very happy with the deal (Biden offered them an exit from Trump’s, and Abe stayed — and proposed Trump for the Nobel Prize. So why the British antagonism? Even if they had to say no, why didn’t they arrange a location or treatment to say no politely. India said no to Trump’s trade deal, politely, in 2020, and to the UK too.
My theory is that Theresa May was taken by the anti-Trump propaganda of Europe and particularly of the German press (see magazine covers of the time). Germany was the leader of Europe (this status has diminished), and its press presented Trump as a racist murderer. May kept trying to get back into the EU, and may have thought that ill-treating Trump would help. Boris Johnson followed May, and was pro-Trump, but his cabinet was not. They acted as if they could recreate the British empire of Queen Victoria — a silly thought. They tried for free trade deals with India, Turkey, and Saudi Arabia, members of the old empire, but they never quite managed anything. COVID made things worse. The UK economy stalled, Johnson was removed, and the current PM, Rishi Sunak, seems to have got nowhere with Biden. Trump re-offered his trade deal during the visit, but he was out of office; Both Biden and Sunak ignored it.
The UK needs free trade with some substantial countries. They are a hub for manufacturing, information, and banking, currently without any spokes. India likely turned them down because the UK no longer has the power to protect them from enemies, China, Iran, Russia.., nor to protect their trade. Aside from rejoining the EU (good luck there), US is the obvious partner. If personality were the problem, there would have been a deal between Rishi Sunak and Joe Biden.
Since leaving the EU, the UK is doing slightly better than Germany, but that’s not saying much. British exports were helped by the cut off of trade with Russia, but that might not last, and London is having trouble trying to remain a financial center, fighting difficult travel and work rules, and the decline of the pound. Maybe it’s Biden’s fault that there is no deal. It’s hard to tell. Last week, the British Foreign secretary, David Cameron, came to visit Trump at Mar a Lago for a good feelings chat and to start on a trade deal should Trump become president. It’s not clear that Trump will become president, but there are at least hopes for a deal, ideally signed at a distance from the baby balloon.
Robert Buxbaum, April 18, 2024 *”Russian collusion” was a big deal at the time. A dossier was supposed show that Trump was a Russian agent. It turned out the dossier was created by Democrats working with the FBI.
Per pound mile of material, the transport cost by ship is 1/4 as much as by train, and about 1/8 as much as by truck. Ships are slower, it is true, but they can go where trucks and trains can not. They cross rivers and lakes at ease and can haul weighty freight with ease. I think America could use many more ferries, particularly drive-on, fast ferries. I don’t think we need new fast rail lines, because air travel will always be faster and cheaper. The Biden administration thinks otherwise, and spends accordingly.
Amtrak gets $30 Billion for train infrastructure this year, basically nothing for ferries.
The Biden administration’s infrastructure bill, $1.2 Trillion dollars total, provides $30 Billion this year for new train lines, but includes less than 1% as much for ferries, $220 million, plus $1B for air travel. I think it’s a scandal. The new, fast train lines are shown on the map, above. Among them is a speed upgrade to the “Empire Builder” train running between Chicago and Seattle by way of Milwaukee. I don’t think this will pay off — the few people who take this train, takes it for the scenery, I think, and for the experience, not to get somewhere fast.
There is money for a new line between Cleveland and Detroit, and for completion of the long-delayed, and cost-over-run prone line between LA and San Francisco. Assuming these are built, I expect even lower ridership since the scenery isn’t that great. Even assuming no delays (and there are always delays), 110 mph is vastly slower than flying, and typically more expensive and inconvenient. Driving is yet slower, but when you drive, you arrive with your car. With a train or plane, you need car rental, typically.
New Acela train, 150 mph max. 1/4 as fast as flying at the same price.
Drive-on ferries provide a unique advantage in that you get there with your car, often much faster than you would with by driving or by train. Consider Muskegon to Milwaukee (across the lake), or Muskegon to Chicago to Milwaukee, (along the lake). Cleveland to Canada, or Detroit to Cleveland. No land would have to be purchased and no new track would have to be laid and maintained. You’d arrive, rested and fed (they typically sell food on a ferry), with your car.
There’s a wonderful song, “City of New Orleans”, sung here by Arlo Guthrie describing a ride on the historic train of that name on a trip from Chicago to New Orleans, 934 miles in about one day. Including stops but not including delays, the average speed is 48 mph, and there are always delays. On board are, according to the song, “15 restless riders, 3 conductors, and 25 sacks of mail.” The ticket price currently is $200, one way, or about as much as a plane ticket. The line loses money. I’ve argued, here, for more mail use to hep make this profitable, but the trip isn’t that attractive as a way to get somewhere, it’s more of a land-cruise. The line is scheduled for an upgrade this year, but even if upgraded to 100 mph (14 hours to New Orleans including stops?) it’s still going to be far slower than air travel, and likely more expensive, and you still have to park your car before you get on, and then rent another when you get off. And will riders like it more? I doubt it, and doubt the speed upgrade will be to 100 mph.
Lake Express, 30 mph across Lake Michigan
Ferry travel tends to cost less than train or plane travel because water traffic is high volume per trip with few conductors per passenger. At present, there are only two ferryboats traveling across Lake Michigan, between Michigan and Wisconsin, Milwaulkee to Muskegon. They are privately owned, and presumably make money. The faster is the Lake Express, 30 mph. It crosses the lake in 2.5 hours. Passenger tickets cost $52 one way, or $118 for passenger and car. That’s less than the price of an Amtrak ticket or a flight. I think a third boat would make sense and that more lines would be welcome too. Perhaps Grand Haven to Racine or Chicago.
Route of the Lake Express. I’d like to see more like this; St. Joseph to Milwaukee say, and along Lake Erie.
Currently, there are no ferries across Lake Erie. Nor are there any along Lake Erie, or even across Lake St. Clair, or along the Detroit River, Detroit to Toledo or Toledo to Cleveland. These lines would need dock facilities, but they would have ridership, I think. New York’s Staten Island ferry has good ridership, 35,000 riders on a typical day, plus cars and trucks. In charge are roughly 120 engineers, captains and mates, one employee for every 300 passengers or so. By comparison, Amtrak runs 300 trains that carry a total of87,000 passengers on an average day, mostly on the east coast. These 300 trains are run by 17,100 employees as of fiscal year 2021, one employee for every 4 passengers. Even at the slow speeds of our trains the cost is far higher per passenger and per passenger mile.
The Staten Island ferry is slow, 18.5 mph, but folks don’t seem to mind. The trip takes 20 minutes, about half as long as most people’s trips on Amtrak. There are also private ferry lines in NY, many of these on longer trips. People would take ferries for day-long trips along our rivers, I think. Fast ferries would be nice, 40 mph or more, but I think even slow ferries would have ridership and would make money. A sea cruise is better than a land cruise, especially if you can have a cabin. On the coal-steam powered, Badger, you can rent a state-room to spend the night in comfort. Truckers seem to like that they cover ground during their mandatory rest hours. The advantage is maximized, I think, for ferry trips that take 12 hours or so, 250 to 350 miles. That’s Pittsburgh to Cincinnatti or Chicago to Memphis.
New York’s Staten Island ferry leaves every 15 minutes during rush hour. Three different sizes of boat are used. The largest carry over 5000 passengers and 100 cars and trucks at a crossing.
A low risk way to promote ferry traffic between the US and Canada would be to negotiate bilateral exemption to The Jones Act and its Canadian equivalent. Currently, we allow only US ships with US crews for US travel within the US.* Cabotage it’s called, and it applies to planes as well, with exemptions. Canada has similar laws and exemptions. A sensible agreement would allow in-country and cross-country travel on both Canadian and US ships, with Canadian and/or US crew. In one stoke, ridership would double, and many lines would be profitable.
Politicians of a certain stripe support trains because they look futuristic and allow money to go to friends. Europeans brag of their fast trains, but they all lose money, and Europe had to ban many short hop flights to help their trains compete. Without this, Europeans would fly. There is room to help a friend with a new ferry, but not as much as when you buy land and lay track. We could try to lead in fancy ferries going 40 mph or faster, providing good docks, and some insurance. Investors would take little risk since a ferry route can be moved**. Don’t try that with a train.
In Detroit we have a close up of train mismanagement involving the “People Mover.” It has no ridership to speak of. Our politicians then added “The Q line” to connect to it. People avoid both lines. I think people would use a ferry along the Detroit river, though, St. Claire to Wyandotte, Detroit, Toledo — and to Cleveland or Buffalo. Our lakes and rivers are near-empty superhighways. Let’s use them.
Robert Buxbaum, January 2, 2024. *The US air cabotage act (49 U.S.C. 41703) prohibits the transportation of persons, property, or mail for compensation or hire between points of the U.S. in a foreign civil aircraft. We’ve managed exemptions, though, e.g. for US air traffic with Airbus and Embraer planes. We can do the same with ferries.
** I notice that it was New York’s ferries, and their captains, that rescued the people on Sullenberger’s plane when it went down in the Hudson River — added Jan. 6.
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.

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.

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.

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.
The first 15 months of the pandemic were grim periods of lockdown, except in Sweden where the health minister declared that lockdowns would not do anything except delay the inevitable. They chose to protect only the most vulnerable, and kept everything else open. By May, 2021, it looked like that was a mistake. Sweden had a seen a sickness and death rate that was fairly average for the world, but high compared to more locked down nordic countries, like Norway, Finland, and Germany. And now vaccines were here that were supposed to be 100% effective, both at stopping the sickness and the spread. We were at the end, opening up, and Sweden had blundered. They had ‘ignored the science,’ as Fauci put it.
Excess mortality January 26 2020 to March 1, 2023, from Our World in Data. I focus on excess deaths here, rather than COVID specifically, because death is a metric that is hard to fudge.
Unfortunately, it quickly became clear that the vaccines were far less than 100% effective. The current estimate is that 2 shots are 24% effective at preventing the disease and 0% effective at preventing the spread. This is a problem in much of medical science these days: successful results tend to be irreproducible, I discuss the reason here. The disease had evolved, and somehow the experiments had not noticed. What’s more they had side-effects (all drugs do). People were dying at a faster rate than before in the US, and in many European countries (see graph below). There was no flattening of the curve suggesting that the vaccine didn’t work. By last year, I had noticed that US COVID deaths did not decrease with the advent of vaccines. Strangely, deaths did not increase as fast in Sweden. By 2022, Sweden was doing better than its lock-down peers. As of today, it’s doing much better. So, what have we learned?
The results of the 6 month Pfizer trial already suggested there might be a problem -that perhaps the vaccine did more harm than good. The above were the results in the Biologics Licence Application (BLA) report (page 23), submitted to the Food and Drug Administration (FDA) to apply for vaccine approval, November, 2021. The vaccine decreased COVID but increased other cause death even more. Suspicious.
The fact that the death rate did generally not go down when a majority were vaccinated and the most vulnerable were already dead suggests that vaccination does not help much. That excess death increased in some countries (Norway, Finland, Germany) suggests that either the side-effects of the vaccine are worse than the disease itself or that some other aspect of the treatment (lockdowns?) were worse than the disease. The vaccine still may be shown to have helped, but it doesn’t look like it helped much. The fact that lock-down countries are doing worse than Sweden suggests that lockdowns actually hurt. This is significant. One thing to learn is that you have a right to not trust medical science: you have a right to be wrong. Mr Spock never trusted Bones’s medicine. You have a particularly strong right to doubt when you have evidence as strong as the map below (excess deaths in Europe as it stood in December 2021). Already Sweden was doing well and the experts were looking very wrong.
A map of excess deaths in Europe as of December 2021. Already many countries had passed Sweden. Eastern and Southern Europe were particularly hard hit.
I can now speculate on the mechanism; why might lockdowns hurt or kill? I suggested it’s loneliness. Perhaps it’s inaction, or mental distress. People would rather get an electric shock than sit a think without doing anything. It might be that lockdowns prevented other medical treatment. Whatever the mechanism, you’d think that our government would have acknowledged, by early 2022, that lockdowns were not working. Instead virtually every state continued lockdowns through a good chunk of 2022 with school closures, limited seating, etc.
I suspect that “long COVID” may be a form of lock-down depression plus associated noxious behaviors: increased drug and alcohol use, lack of exercise, and avoiding treatment for health problems. I suggested iodine hand wash (and gargle) to stop the disease spread (I imagine it’s on surfaces), and still think it’s a good idea. Iodine is cheap and it definitely kills all germs. Other anti-isolation nostrums include exercise, lithium, aspirin, letters, and hydroxycholoroquine. There was reasonable statistical evidence for several of these things helping, though Fauci denied it. Perhaps they only helped via ‘the placebo effect’. But placebo cures are real, especially for mental problems.
Robert Buxbaum, March 30, 2023. As an add-on (April 2, 2013), I’d like to show the decline in life-expectancy in the US compared to other countries. Isolation is a killer. A lot of the blame goes to Fauci for continuing to push socially isolating solutions as “the science”, while blasting any who say otherwise. We’ve lost 3 years of life-span in 3 years — preventably avoided — when other countries have lost zero or one. There could be no greater inditement of the health management.
This is from the Financial Times. The US is doing worst of all in terms of lives lost to the pandemic and it continues. Isolating people is torture. We then blame them for feeling distrust. I blame Biden and Fauci.
