(Japan and Cherry Blossoms)SECTION I: Japanese Central Bank Governor of Rwanda
Masaya Hattori (1918 - 1999) worked for six years from 1965 as governor of the central bank of Rwanda.
(http://ja.wikipedia.org/wiki/%E6%9C%8D%E9%83%A8%E6%AD%A3%E4%B9%9F)
His memoir is still highly praised in Japan not only because he was the first Japanese Vice President of the World Bank but because he was once Governor of the Central Bank of Rwanda. It is truly interesting that a Japanese economist contributed to Rwanda 30 years before the African country suffered the cruel civil war and genocide around 1994.
His success in Rwanda is ascribed more to his being Japanese rather than to economics.
Though he studied in America and worked in Paris while belonging to the Bank of Japan after WWII, he did not see the situation of Rwanda from the European/American side.
He observed Rwanda in comparison with Japan that have never been colonized by European/American powers. He did not despise Africans. He took them as the same human beings. In other word, Masaya Hattori truly tried to help Rwanda get rid of evil influences of Europe and America so as to be economically and financially independent. So, the Japanese governor did not concede, in his mission, to Belgians who had virtually colonized Rwanda till 1962.
The Rwanda government extended his term, originally one year, till Masaya Hattori decided to come back to Japan, since he thought the head of the central bank of Rwanda should be a Rwandan.
The central bank of Rwanda under leadership of Masaya Hattori was not a mere bank. It functioned as a government agent in charge of industry, trade, economy, and finance. The technical functionality of the central bank worked effectively only when the fundamental social conditions were secured and the overall national economy was given a chance of growth, getting rid of the remaining yoke of the past colonial rule.
In other word, a central bank should be an integral part of the administrative mechanism so as to contribute to prosperity of a nation.
As long as a central bank in an African nation serves ex-colonial rulers, it never helps a nation.
As long as a central bank in any country serves financial rulers, it never helps a nation.
Once major European nations and America were colonial rulers in the world.
Today, major players in the global financial market are colonial rulers in the global financial market, including central banks.
We have to choose a right person for a central bank governor.
SECTION II: Newton's Tradition
It happened to me, an interest in a top.
Traditionally Children used to play spinning a top even in Japan, since there are scores of different types of tops in Japan.
(http://www.fsinet.or.jp/~eohashi/k/kakuti.htm )
But, it is not easy to explain why a top does not fall so easily while spinning and tilting.
Of course, teachers of science or scientists would explain it using some scientific concepts. But, it is not easy to comprehend it.
What stops a spinning top from falling over? I checked some Web pages and Internet sites dealing with this question. The most understandable and educative explanation was finally found in a Web site related to Cambridge University.
Put simply, gravity is too small to make a spinning top fall over in comparison with the spinning power or energy.

A spinning top

What stops a spinning top from falling over? Gyroscopic effects are what it's all about. Here are two explanations, including one that doesn't rely on any knowledge of the gyroscopic effect. See which you prefer. One thing's for sure, anything to do with the gyroscopic effect is counterintuitive!
Explanation A:

Explanation B (less technical):
What stops a spinning top from falling over?
All we need to show is that the force of gravity is insufficient to cause the top to fall.
1. The only force acting to push the top over is gravity.
2. First think what happens when the top is not spinning. It falls over and we get a feel for how long it takes for the top to fall and how fast it is going when it falls.
3. This gives us a feel for how much angular motion that gravity alone can give to the top if it were to fall over. Let's call this angular motion "spin", but note that gravity can only create "spin" about a horizontal axis.
4. Now when we get the top going normally (spinning about a vertical axis) we can tell that we are giving the top much more "spin" about the vertical axis than gravity managed to achieve about a horizontal axis when the top fell over.
5. With the top spinning really fast, let's suppose the top were to manage somehow to fall over, with its axis horizontal. Then we would see that the top possesses a large "spin" about a horizontal axis. The "spin" we'd then have is far greater than anything gravity alone can produce. Since there are no other forces acting other than gravity, the top can't have fallen over (if not gravity, what else is there to generate the required "spin" we need about a horizontal axis?).
6. Things are different if the top is spinning quite slowly, roughly the same sort of speed as the top got to in 2. Then we see the top is verging on toppling. This is because gravity is now capable of producing the "spin" required about the horizontal axis as observed when the top falls over.
7. If the top is spinning very fast then it is ultra stable because the effect that gravity can produce is way too small.
[note: to make this read more technically correctly, replace the word "spin" when it occurs with the words "angular momentum"]
The minimum spin speed (in revs per second) for a typical top to be stable is roughly equal to √g/a where g=9.81m/s2 and a is the radius of the top. This is about 10 revs per second for a typical "pump-up" toy top, like the one shown in the picture at the top of the page.

----------
It is very understandable and matches my analysis on the spinning energy and the gravity.
But, who in Wall Street can explain what stops a spinning top from falling over?
Who among economists can explain what stops a spinning top from falling over?
But, Newton is so great that his influence still lives in part of England.
So, check the Newton's prophecy on the year 2060 (as I wrote yesterday)!
Also, let's check the illustration below.
The red allows indicate directions of force.
Note that the gravity does not cause a vertically downward movement to the molecules of the top at the lowest position.
The gravity causes a movement along a tangent to an imaginary (green) circle presenting the rotation of the object (the top) with the supporting point at the bottom of the axis of the top on the floor.
*** *** *** ***
Even teachers of science and scientists cannot explain well why a rotating top does not easily tilt and fall down.
It is partly because they think the gravity always causes a vertically downward movement to molecules, and partly because they think that the gravity is far larger than the power of spinning.
Even when the object further tilts down to hit the floor but the floor is immediately taken away, the top rotates and circulates without further falling down to the earth, if the direction of the synthesized forces is just horizontal at the floor level.
The spin of a top is regarded as real economic activities and the gravity as deficits in the government budget.
As long as real economic activities are strong enough, it will not fall over even if a financial state of a nation tilts within a certain limit.
(Another key is the frictional force acting at the supporting point of the axis. Without this friction, a top cannot stand. The frictional force is regarded as people's will to live.)
Mar 4:2 And he taught them many things by parables, and said unto them in his doctrine,
Mar 4:3 Hearken; Behold, there went out a sower to sow:
Mar 4:4 And it came to pass, as he sowed, some fell by the way side, and the fowls of the air came and devoured it up.
