Correlation between NASDAQ price, Corn and Gold(Corr=0.945)

 I wrote Python code which shows Correlation between NASDAQ price, Corn and Gold(Corr=0.945). Corn and Gold are best mix I have found. https://gist.github.com/Kouhei-Takagi/a1a9b073f6cd6dacb7eb1ea871d8fd3c I changed some important parts. https://gist.github.com/Kouhei-Takagi/5becaf7c3a24d63ac9c56856e81297f2

Resources of Earth

2018/10/5. Resources of Earth: 80/20 rules 

We human use resources of earth. The populations of human are about 7 billion people. When the numbers of resources which we can use in a year, is 100 (Normalization:Scientific method), how are 100 resources distributed?

I think the 80/20 rules is applied.
In fact, 80 resources are distributed to the 20% people (80/20 class). And 20 resources are distributed to the 80% people (20/80 class). So there are 2 classes, 80/20 class & 20/80 class.

Further more, how many people can enter the 80/20 class? Human populations are 7 billion. So 20% is 1.4 billion.

1.4 billion people... This population is as same as population of China country.


If China becomes king in the world, no other country can be 80/20% class.

Cheaper work

2016/12/29. Cheaper works: Hard competition makes expensive work cheaper. In Japan, there are some people who thinks there are a lot of workers, and they are exchangeable easily.

Now, Japanese society is standing on that thought, and Japanese system hardly stands. This is by the patience of Japanese. When the breaking point of Japanese system comes, the counter of patience will keeps long time. And I think that communism never comes in Japan. Because Karl Marx doesn't think about human populations decreasing...

None feedback

2016/12/29. None feedback from others in Japanese company Feedback is not always visible or sound , especially the fact of feedback is hidden by various suits. And in Japanese company, I often see the scene that ignorance to the people who did careless mistakes. Others don't say anything about the careless mistakes in front of the person, but in background, others speak ill of the person. This is none feedback. None feedback from others is very bad feedback, but in Japanese company, it is often. Why none feedback happens? In my experience, there are some reasons. When the person who made mistakes is upper than others, others want the person to fall out. When the person is equal level to others, others want the person not to promote. When the person is lower level, others want to make the person the targets for inner circle. I rethink that none feedback in company is bad signal for organization... None feedback happens when the company is bad statements!!!
