Handsaw comparison – Japanese pull-cut versus Western push-cut

Filed under: Japan, Technology — Tags: , , — Nicholas @ 03:00

On Facebook, Paul Sellers posted a couple of photos showing the differences between some traditional western hand saws, which cut on the push stroke, and traditional Japanese hand saws, which cut on the pull stroke:

When you hear people say Japanese saws cut better, cut cleaner, cut faster, cut easier, usually it’s not necessarily true. In reality the Japanese saws cut on a pull stroke and the western saw on a push. When sharpened properly both cut very well. The difference for me is that one is a throwaway, the other a keeper for a lifetime. I own saws made in England and the USA that are totally functional and range in age from between the early 1800s 1860s and some up to date that I use daily. You can make any saw any thickness you like and it will work well.
Just saying.

The main difference nowadays is you throw away the Japanese saws because you can’t sharpen them whereas a decent western saw can be sharpened, well, for 200 years when you learn how. Most people can master saw sharpening with an hour of practice.

Fort Drum – America’s concrete battleship

Filed under: Asia, History, Japan, Military, Pacific, USA — Tags: , , — Nicholas @ 02:00

Published on 15 Sep 2016

After the United States acquired the Philippines from Spain, the U.S. Board of Fortifications recommended that important harbors be fortified. This led to the development of defenses on several islands at the mouth of Manila and Subic Bays. One of these was El Fraile Island which would later become Fort Drum, America’s concrete battleship.

The Battle of Midway, 4-7 June 1942

Filed under: History, Japan, Military, Pacific, USA — Tags: , , — Nicholas @ 03:00

Last month, Victor Davis Hanson recounted the American side of the Battle of Midway, which many historians see as the turning point of the Pacific War:

Seventy-five years ago (June 4-7, 1942), the astonishing American victory at the Battle of Midway changed the course of the Pacific War.

Just six months after the catastrophic Japanese surprise attack on Pearl Harbor, the U.S. crushed the Imperial Japanese Navy off Midway Island (about 1,300 miles northwest of Honolulu), sinking four of its aircraft carriers.

“Midway” referred to the small atoll roughly halfway between North America and Asia. But to Americans, “Midway” became a barometer of military progress. Just half a year after being surprised at Pearl Harbor, the U.S. Navy had already destroyed almost half of Japan’s existing carrier strength (after achieving a standoff at the Battle of the Coral Sea a month earlier).

The odds at the June 1942 battle favored the Japanese. The imperial fleet had four carriers to the Americans’ three, backed up by scores of battleships, cruisers and light carriers as part of the largest armada that had ever steamed from Japan.

No military had ever won more territory in six months than had Japan. Its Pacific Empire ranged from the Indian Ocean to the coast of the Aleutian Islands, and from the Russian-Manchurian border to Wake Island in the Pacific.

Yet the Japanese Navy was roundly defeated by an outnumbered and inexperienced American fleet at Midway. Why and how?

Intro to the Solow Model of Economic Growth

Filed under: China, Economics, Germany, Japan — Tags: , , — Nicholas @ 02:00

Published on 28 Mar 2016

Here’s a quick growth conundrum, to get you thinking.

Consider two countries at the close of World War II — Germany and Japan. At that point, they’ve both suffered heavy population losses. Both countries have had their infrastructure devastated. So logically, the losing countries should’ve been in a post-war economic quagmire.

So why wasn’t that the case at all?

Following WWII, Germany and Japan were growing twice, sometimes three times, the rate of the winning countries, such as the United States.

Similarly, think of this quandary: in past videos, we explained to you that one of the keys to economic growth is a country’s institutions. With that in mind, think of China’s growth rate. China’s been growing at a breakneck pace — reported at 7 to 10% per year.

On the other hand, countries like the United States, Canada, and France have been growing at about 2% per year. Aside from their advantages in physical and human capital, there’s no question that the institutions in these countries are better than those in China.

So, just as we said about Germany and Japan — why the growth?

To answer that, we turn to today’s video on the Solow model of economic growth.

The Solow model was named after Robert Solow, the 1987 winner of the Nobel Prize in Economics. Among other things, the Solow model helps us understand the nuances and dynamics of growth. The model also lets us distinguish between two types of growth: catching up growth and cutting edge growth. As you’ll soon see, a country can grow much faster when it’s catching up, as opposed to when it’s already growing at the cutting edge.

That said, this video will allow you to see a simplified version of the model. It’ll describe growth as a function of a few specific variables: labor, education, physical capital, and ideas.

So watch this new installment, get your feet wet with the Solow model, and next time, we’ll drill down into one of its variables: physical capital.

The Ally From The Far East – Japan in World War 1 I THE GREAT WAR Special

Filed under: Asia, China, History, Japan, Military, Pacific — Tags: , , , , — Nicholas @ 05:00

Published on 22 May 2017

Japan’s participation in World War 1 is an often overlooked part of their history – even in Japan itself. Their service as one of the members of the Entente marked the climax of a development that started with the Meiji Restoration, a way out of isolation and into the global alliance system. This brought Japan more power and was also very lucrative. And after fighting in the Pacific Theatre of World War 1, the Siege of Tsingtao and contributing the Japanese Navy to the war effort, Japan had a seat at the table of the Versailles peace negotiations.

Growth Miracles and Growth Disasters

Filed under: Economics, Japan — Tags: , , , , — Nicholas @ 02:00

Published on 26 Jan 2016

In previous videos, you learned two things.

First, that there can be large disparities in economic wealth among different countries. And second, you learned that one key factor drives that disparity: growth rate. As we said, it changes everything. But just how transformative is a country’s growth rate?

Take Argentina, for example.

In 1950, the Argentine standard of living was similar to that of many Western European countries. Up until 1965, Argentina’s per capita income was ahead of many of its neighbors.

On the other hand, Japan in 1950 was on the other end of the spectrum. Japan had been ravaged by war and was only just beginning to find its economic footing again. At that time, Japan’s standard of living was roughly the same as that of Mexico.

It was quite poor, compared to the Argentina of the same era.

But look at what’s happened in the past 65 years.

Japan today is one of the world’s most prosperous countries. Since 1950, it has managed to double its living standards about every eight years. Argentina, on the other hand, has stagnated. Once, Argentina had double the standard of living of Japan. But Japan now doubles them today, with a standard of living 10 times higher than the one it had in 1950.

In economic terms, Japan is what we would call a growth miracle. It’s in the same class as other growth success stories, like South Korea and China which have experienced the “hockey stick” of prosperity. (India seems like it may have started on this path as well.)

These countries are proof of one thing: with the right factors, a poor country can not only grow, but it can do so quickly. It can catch up with developed countries at an astonishing rate.

What took the United States two centuries of steady growth can now be achieved by other countries in about one-fifth the time. Catch-up can happen in 40 years — about the span of a generation or two.

That’s the good news.

The bad news is, while growth can skyrocket in some countries, growth isn’t guaranteed at all.

Argentina is an example of this. It grew well for a time, and then it stalled. Even worse than Argentina, are countries like Niger, and Chad, which are the very worst of growth disasters. Not only are these countries in extreme poverty, but they also have little to no growth. More than that, these countries have never experienced substantial growth in the past.

But why does that all matter?

It matters because growth isn’t just about numbers. It’s not just about more goods and services. When a country grows, its citizens often end up with longer, healthier, and happier lives. Conversely, the countries that are growth disasters have citizens in poverty, with shorter and less happier lives.

As bleak as this seems, it’s the plain truth: while growth miracles are possible, growth disasters are, too.

Which leaves us with another question: what causes either state?

What leads to growth, prosperity, health, and happiness? And then, what leads to the opposite situation?

We’re excited to share the answer, but that’s a topic for future videos.

For now, check out this video to get up to speed on growth miracles and growth disasters.

Another Japanese “destroyer” joins the fleet

Filed under: China, History, Japan, Military — Tags: , — Nicholas @ 03:00

Due to a long-standing aversion to calling certain kinds of vessels by their most appropriate name, the Japanese Maritime Self-Defence Force (because Japan’s constitution prohibits the country having a “navy”, post-1945) commissioned their latest “destroyer” last week:

JS Izumo DDH-183, sister-ship of the just-commisioned JS Kaga DDH-184, both helicopter-equipped destroyers, officially.

I know what you’re thinking … “That doesn’t look like a destroyer to me” … but that’s what Japan officially designates ships like this to be, so that’s what they’re called. Strategy Page has more:

On March 22nd Japan put into service a second 27,000 ton “destroyer” (the Kaga, DDH 184) that looks exactly like an aircraft carrier. Actually it looks like an LPH (Landing Platform Helicopter) an amphibious ship type that first appeared in the 1950s. This was noted when Izumo, the first Japanese LPH was launched in 2012 (it entered service in 2015). The Izumos can carry up to 28 aircraft and are armed only with two 20mm Phalanx anti-missile cannon and launcher with sixteen ESSM missiles for anti-missile defense.

LPHs had no (or relatively few) landing craft but did carry a thousand or more troops who were moved ashore using the dozen or more helicopters carried. The first American LPH (the USS Iwo Jima) was an 18,400 ton ship that entered service in 1961, and carried 2,000 troops and twenty-five helicopters. Until Izumo showed up, several nations operated LPHs, and Britain and South Korea still do. The U.S. retired its last LPHs in the 1990s, but still have a dozen similar ships that include landing craft (and a well deck in the rear to float them out of) as well as helicopters. A few other nations have small carriers that mostly operate helicopters but carry few, if any troops.

The Izumos are the largest LPHs to ever to enter service. It differs from previous LPHs in not having accommodations for lots of troops and having more powerful engines (capable of destroyer-like speeds of over fifty-four kilometers an hour). Izumo does have considerable cargo capacity, which is intended for moving disaster relief supplies quickly to where they are needed. Apparently some of these cargo spaces can be converted to berthing spaces for troops, disaster relief personnel, or people rescued from disasters. There are also more medical facilities than one would expect for a ship of this size. More worrisome (to the Chinese) is the fact that the Izumo could carry and operate the vertical take-off F-35B stealth fighter, although Japan has made no mention of buying that aircraft or modifying the LPH flight decks to handle the very high temperatures generated by the F-35B when taking off or landing vertically. The Chinese are also upset with the name of this new destroyer. Izumo was the name of a Japanese cruiser that was a third the size of the new “destroyer” and led the naval portion of a 1937 operation against Shanghai that left over two-hundred-thousand Chinese dead. The Chinese remember all this, especially the war with Japan that began unofficially in 1931 and officially in 1937.

“[M]ost of what journalists know about radioactivity came from watching Godzilla

Filed under: Japan, Media, Science, Technology — Tags: , , , — Nicholas @ 03:00

Charlie Martin explains why the “news” out of Fukushima lately has been mostly unscientific hyperventilation and bloviation:

On February 8, Adam Housley of Fox News reported a story with a terrifying headline: “Radiation at Japan’s Fukushima Reactor Is Now at ‘Unimaginable’ Levels.” Let’s just pick up the most exciting paragraphs:

    The radiation levels at Japan’s crippled Fukushima nuclear power plant are now at “unimaginable” levels.

    [Housley] said the radiation levels — as high as 530 sieverts per hour — are now the highest they’ve been since 2011 when a tsunami hit the coastal reactor.

    “To put this in very simple terms. Four sieverts can kill a handful of people,” he explained.

The degree to which this story is misleading is amazing, but to explain it, we need a little bit of a tutorial.

The Touhoku earthquake and tsunami on March 11, 2011, along with all the other damage they caused, knocked out the TEPCO Fukushima Daiichi (“plant #1”) and Daini (“plant #2”) reactors. Basically, the two reactors were hit with a 1000-year earthquake and a 1000-year tsunami, and the plants as built weren’t able to handle it.

Both reactors failed, and after a sequence of unfortunate events, melted down. I wrote quite a lot about it at the time; bearing in mind this was early in the story, my article from then has a lot of useful information.

[…]

So what have we learned today?

We learned that inside the reactor containment at Fukushima Daini, site of the post-tsunami reactor accident, it’s very very radioactive. How radioactive? We don’t know, because the dose rate has been reported in inappropriate units — Sieverts are only meaningful if someone is inside the reactor to get dosed.

Then we learned that the Fukushima accident is leaking 300 tons of radioactive water — but until we dig into primary sources, we didn’t learn the radioactive water is very nearly clean enough to be drinking water. So what effect does this have on the ocean, as Housley asks? None.

The third thing we learned — and I think probably the most important thing — is to never trust a journalist writing about anything involving radiation, the metric system, or any arithmetic more challenging than long division.

Autarky is not the answer

Filed under: Economics, History, Japan, USA — Tags: , , , — Nicholas @ 02:00

Warren Meyer on the idiocy of Trump’s economic nationalist notions:

Think about the corollary of Trump’s economic nationalism, particularly if everyone followed this same approach. If one skews all the rules and taxes and prohibitions so everything must be sourced domestically, then if a country does not have some particular resource or skill domestically, it is out of luck. No domestic rare earth metals? Sorry.

But governments and powerful people seldom calmly accept that something they critically need is not available. They will be tempted to go and take it. The worst, most violent empire building of the last 100-150 years has occurred when countries have pursued economic nationalism. Think of the colonialism of the late 19th century. Today we happily trade with South Africa and other countries for valuable resources, but in that time of economic nationalism, if a country wanted access to these resources, it felt it had to control the land and the people. Hitler in the 1930’s wanted to make Germany self-sufficient in agricultural goods and certain other resources, and the only way to do that was to go and grab other people’s land and resources.

The best example of all of this phenomenon is, I think, Japan in the 1930’s. Japan felt that it was resource poor and under Trump’s theory of economic nationalism, it felt it had to control oil and other resources it did not have domestically. So it plotted to go take it. When the US instituted a trade embargo in these very goods to punish Japan’s aggressiveness in China, it just accelerated Japan’s thinking in this area, convincing it for good it had to control these resources, and it was soon invading the oil-rich islands of what is now Indonesia. This example is all the more telling because Japan actually found true prosperity after the war when it traded peacefully for these resources. Unfortunately, it adopted economic nationalism, via MITI, of another form and helped manage themselves into a 20-year recession, but that is another trade-related story for another day.

QotD: Historical clangers in The Last Samurai

Filed under: Japan, Media, Quotations — Tags: , , , , — Nicholas @ 01:00

… the movie is seriously anti-historical in one respect; we are supposed to believe that traditionalist Samurai would disdain the use of firearms. In fact, traditional samurai loved firearms and found them a natural extension of their traditional role as horse archers. Samurai invented rolling volley fire three decades before Gustavus Adolphus, and improved the musket designs they imported from the Portuguese so effectively that for most of the 1600s they were actually making better guns than European armorers could produce.

But, of course, today’s Hollywood left thinks firearms are intrinsically eeeevil (especially firearms in the hands of anyone other than police and soldiers) so the virtuous rebel samurai had to eschew them. Besides being politically correct, this choice thickened the atmosphere of romantic doom around our heroes.

Another minor clanger in the depiction of samurai fighting: We are given scenes of samurai training to fight empty-hand and unarmored using modern martial-arts moves. In fact, in 1877 it is about a generation too early for this. Unarmed combat did not become a separate discipline with its own forms and schools until the very end of the nineteenth century. And when it did, it was based not on samurai disciplines but on peasant fighting methods from Okinawa and elsewhere that were used against samurai (this is why most exotic martial-arts weapons are actually agricultural tools).

In 1877, most samurai still would have thought unarmed-combat training a distraction from learning how to use the swords, muskets and bows that were their primary weapons systems. Only after the swords they preferred for close combat were finally banned did this attitude really change. But, hey, most moviegoers are unaware of these subtleties, so there had to be some chop-socky in the script to meet their expectations.

One other rewriting of martial history: we see samurai ceremoniously stabbing fallen opponents to death with a two-hand sword-thrust. In fact, this is not how it was done; real samurai delivered the coup de grace by decapitating their opponents, and then taking the head as a trophy.

No joke. Head-taking was such an important practice that there was a special term in Japanese for the art of properly dressing the hair on a severed head so that the little paper tag showing the deceased’s name and rank would be displayed to best advantage.

While the filmmakers were willing to show samurai killing the wounded, in other important respects they softened and Westernized the behavior of these people somewhat. Algren learned, correctly, that ‘samurai’ derives from a verb meaning “to serve”, but we are misled when the rebel leader speaks of “protecting the people”. In fact, noblesse oblige was not part of the Japanese worldview; samurai served not ‘the people’ but a particular daimyo, and the daimyo served the Emperor in theory and nobody but themselves in normal practice.

WW2: The Resource War – III: The Engines of War – Extra History

Filed under: Economics, Europe, History, Japan — Tags: , , — Nicholas @ 03:00

Published on 19 Apr 2016

*Sponsored* Hearts of Iron IV comes out on June 6!

The armies and technology of World War II required a vast supply of resources. A close look at Germany and Japan shows how the need to secure those resources played a significent role in determining strategy throughout the war.
____________

The armies of World War II needed a vast supply and variety of resources. The Allies had many of those resources on their side, but the Axis powers did not. Germany imported many of its resources from countries it would soon be fighting, and needed their war strategy to account for the acquisition of those resources. The Molotov-Ribbentrop Pact signed with the USSR set up a trade agreement to bring them oil from Russia for a while, in addition to establishing temporary non-aggression with the Soviets. When the war began in earnest, Germany targeted Norway with its supply of aluminum and iron as well as its access to the even more resource-rich Sweden. Conquering France also gave them access to rich farmland to feed the troops. But even though they had gained control of the oil fields in Romania, it wasn’t enough to power their war machine. Many Nazi generals wanted to target North Africa for this, but Hitler had his sights set on the Soviet Union and wound up squandering much of Germany’s reserves in a fruitless effort there. Meanwhile, Japan’s entrance into the war had cost them their primary trading partner: the United States. The Japanese army wanted to pursue the Northern Expansion Doctrine (Hokushin-Ron) and push through China into Siberia, wounding the USSR in the process. They attempted this strategy, but the Soviets met them in Mongolia and pushed them back in the Battle of Khalkhin Gol. So they turned to the Southern Expansion Doctrine (Nanshin-Ron) advocated by the navy, and began to sweep up islands in the Pacific. They planned to strip the European colonial powers of their holdings, and they succeeded in capturing 90% of the world’s rubber production. But the US responded by synthesizing rubber, and built an industry so large that even today, more rubber is synthesized than harvested. If World War I was the first industrial war, marked by mass production and industrial capacity, then World War II was the first scientific war, marked by advancements like synthesis, radar, and jet engines.
