Role of school

Today, I read the article about secret of nada-highschool elite education system.
The article itself is intersting, but I feel a little strange for it.

I think education should be free for everybody, not special people.
If they want to learn somethings, education system support them.It is true education, I think.
Education should not be for a person who study hard. It should be equal to everyone if they want to becaome studying. 

And second reason I feel strange is that this article said that this school teach student to think rather than learn. Of course, it is good thing and is true, but personally I didn't like it. I didn't want school to force something to me.
In my highschool (shizuoka highschool), school is very liberal and allmost every student didn't expect school lecture. But most good thing is that there are many talented student gathering and that stimulate each other.

Recently, we can learn everywhere using internet + basic usage of English, so important  role of school is, as above article saying, 
to argue or think things, but most important role of school is to provide circumstance where talented student or unique students are gathered and stimulate each other.

Cloud program using App Inventor

As writing this, I tried App Inventor on chrome OS.
I can program app very easily (about 30 min) and all needed are
  • PC ( cheap one is ok )
  • Smart Phone
  • Wifi accesibility ( in home )
  • gmail account

Chrome OS works on browser but it is not neccesary to install linux app.
Detail is here but we can program my own app in app inventor's website and reflect programing instantly to my smartphone via home wifi network.

I programed my first android program according to this article.
Amazing, because when I tried Android studio on linux, android studio is very very heavy and furthermore it took sometimes to run app in my smartphone (plus needed usb-cable).
This is very wonderful product so I want to teach my child(7 years old) this usage !

To erase anxiety

Sometimes, we feel anxiety at work. And that makes my brain tired.

For me, there are several ways to conquer.

  1. Sleep well: this is best way for me. When my brain was tired of many things, I slept and after waking up, in many case, my brain became simple
  2. Run: Sports is good way to refresh. When running, I can think of many situations and running makes my brain stimulated, so after running, my brain became refresh.
  3. knowing it not such a big issue .And for it, seeing things with wide rage of eyes can give me wisdom. 
Especially no.3 is way of thinking and is like a zen.
But my zen book which I liked said that 99% anxiety is "void" (I'm not sure it is collect word in english). It was made by themselves.
At first, I can't understand it by heart but recently I think it is true things.
And it also reduce my wasting time enormously because 99% of things are indeed "garbage" things. Thinking it is very important issue, I think..

Going back to the main topic,
Human brain is very unique organ so thinking anexiety with brain mechanism and way of thinking like zen might be a good way to fully understand human beings.

Using Chrome OS and doing cloud programing

I'm using linux OS (ubuntu) for about 6 years, and I happend to find Cloudready, which might be easy to install Chrome OS, so I tried it.

I've somehow installed it and it works good.
My netbook is not high performance model(CPU=N450) but it works smootly. Chrome OS is good way for old computer to be utilized.

Today, I'm using cloudready and I liked it. It is browser based OS. It only works with browser but like android phone, many add-ons(chrome browser app) are available so it is not big problem.
And I wanted to do android programing with Chrome OS so I searched and found good one. App Inventor.
App inventor is cloud-based programing tool and we can use it by installing chrome browser app to chronium browser. I happend to watch this BBC video last week saying kids can learn programing.
We can easily do programing in such a cheap computer, amazing.

---- appending: 2015.12.23 ------
At first I thought Chrome OS (Cloudready) is good, but using this OS , I change my opinion. It often hanged up. It might be due to chonium browser because in this case, it always waited response from site and I can't release browser or can't effect ctl+alt+del key.
Today, I restarted my computer 2 times for about 3 hours usage !

Handling informations

Recently due to a progress of IT, we can easily gather and handle many informations at any time any place if they have a curiisity.
My method is like this.

1. Getting informations, reading informations
  I use RSS reader(Feedly) and mail magazine and those are good way to get informations efficiently, but most good method for me is by newspaper (real newspaper). 
Newspaper is coverd with wide range of information so for me is the best resource. I always get up at early about 4:30 AM and have a coffee and read newspaper about 30 min. This is a best time for me. And after reading it and find some intersting articles, I take a picture by tablet and send it to my google drive. Before IT is not convinient like this, I scrap these by folders but storing in cloud is very convinient because I can aceess my own resources at any place at any time.
And my most important information resources is books. I like books very very much from children. I spend about 2 or 3 times a week  at book shops when I was a way back to my home and read many books and it is very wonderful time for me.
But I have limited amount of money to spend for books so I use public library. Recent liblary is progressing so I can reserve books by smartphone so when I found intersting books, I memo book titles and reserved it via smartphone ! It's amazing.

I also use my personal bookmark website and webserfing my favorite sites and it is also good way but sometimes spend too much time ..

And if I find some intersting articles mainly about scientific fields, I pushed this articles to my kindle simply putting "send to kindle"botton, then read them at about commuter time. I like kindle because it is light, not waste of battely, and very gentle to my eyes. My kindle has a dictionary so if I can't understand a meaning of words, just touch words. It is very convinient function.

2. Throwing informations to my information boxes
 As descrived above, I use google drive, and this is very good storage service because it is free! And I also use gmail to save articles url. For me, this is very simple method. I used gmail for a long time and gmail's tag function is very useful so I categorize these informations. These category is changing according my curiosity and gmail function is very frexible.
And I sometimes added some informations(urls or etc) to my personal bookmark website.
I also saved url's using bookmark function. I use Feedly and youtube and these have a bookmarking funtions and these work very good!

These action is like throwing informations to some basket and doing it in a easiest way and also be able to access these informations at any place any time is most important issue, I think.
And after a certine time passing, these informations was matured inside my body and turned out to be a meaning infomations.

3. Summarizing informations
 It is my most important works. This works means understanding informations.
Especially in intersting non-fiction books, there are many good informations existed so I reserved some important informations. I use very traditional ways. Papers.
I have a notebook (loose-leaf type) and a system notebook(filofax type). When I find some intersting informations at bookstore or reading magazine at cafe, I pulled my system notebooks and write down. It is convinient way for me.
And  when I want to write down more informations, I used my notebook mainly after finishing reading books. It take about 30 min but I like this way.
It is like when I was a highschool students.

4. Reserching or memorizing some idea
 Sometimes, I want to reserching something and in such occasions, I used google docs and it is very useful tools because I did it in any time any place. Also use google keep and system notebook to memo something, like to-do list or something hint etc. 
It helps releasing my brain's shortterm memory so feel relaxing !

5. Writing down something
 This is what I'm doing. Before web services was appeared, publishing somethings is very hard for ordinary person, but now is very good world and everyone who have a accessibility to internet can publish something in a very easily way.
So barrier of ordinary people and writer is low, I think. It depends on what they are.

Sports is good for health, especially for brain

I'm interested in relationship between stress and brain function.

Mechanism of brain is very intersting because brain is very accurate organism.
When we feel about fear, stress, brain alart to amygdala in brain, then amygdala make signal to hypothalamus then hypothalamus makes singnal to hypophysis ,then hypophysis make signal to adrenal gland then adrenal gland release cortisol which is stress hormone.This route is called "HPA" .
Cortisol is circuited via blood around our body then affected many organ including brain.

Cortisol is good when emargence situation was happend, but when we continuously feel stress alltime, cortisol level is always high and it is bad for brain, especially for hippocampus which is important for memory.

My favorite book "Method of usage of waking up early" said that 3 important issue for health is "sleep 7 hours", "good food" and "good exercise". The author kisou kubota has jogging 3 days per week since he was 46.
I bought this book about 5 years before and has continued waking up about 4:30 AM, continuing jogging (recently walking or something like that) and eating breakfast with rice with fermented soybeans and yogurt.

This book said that good exercise stimulate prefrontal area which is major player in brain. And good exercise makes us good tiredness that make us sleep early.
Like my experience, during running, my brain works actively because I must watch if car's coming or bycles suddenly come.
And after running and sometimes one cup of beer!, good sleepiness come and sleep soon.  This book said good sleep reduce level of cortisol. From my experience, when I waked up after good exercise, my brain is very fresh and keep good condition,so this triangle is very good for me.
And recently, I read Sparks which said almost same things.

So thinking stress from the point of brain mechanism is very intersting thing.

Soroban school

Recently, my son went to soroban school near our house (2min. By walk from our house )
This school is held in private house so it dose not seem like "school". Soroban is very good custom in Japan, I think, because they use fingures very rapidly so it stimulate brain. Soroban specialist can calculate adding, multiplication without soroban. It is amazing !

He likes soroban school because he can play outside with their friends after finising soroban school !

Mini 4WD

When we went to shizuoka, we went to sumpu takumi-juku and took part in plastic model making course. My son made dangan-racer which is one of mini 4WD series and enjoyed very much.
Dangan-racer is small plastic-model toy car, running very fast. But it needed special circuit couse so if we want to run this car, we have to find hobby shop which has special circuit couse, so we went to hobby shop(hobby zone) where it has special circuit couse. on 6 Sep.

There were special course but too small and it is for mini 4WD.
In this shop, there are many mini 4WD plastic model exhibited and they are about 1000yen included motor, not so expensive, so we want to buy it.
This shop plans to do racing event this month, that's one reason we bought mini 4WD.

Then we went to mini 4WD tournament.
There were much people.

Many people had their special tools !

We participated in junior school tournament.
Race was done with 3 times round and one round included jumping run.
My son's car was crached at this point so he lost first contest.
But it was fun time.

Camp at north of Kyoto (21 Sep.)

Second day, I got up at 5 am and it was cool, not cold but a little cold morning.
I boilded water for coffee and morning soup.

After eating breakfast and pulled down a tent, we walked around there.

We climbed up to the hill for big stone called "asobi ishi", but after walking up about 20 min., we found big honey comb in front of the stone !

After enjoying walking, we left there and drove around tango peninsula.
First, we went to kumihama, beautiful small village.

Then drove through Route 178 to north-east, then south.

We reached to ine where many houses were in front of the sea.
These houses have ship garages inside houses.

Then final distination,amano-hashidate. At first, I planed to go to maizuru but when we arrived there, it was 3:40 pm, so changed plan.

Amano-hashidate was large so there are 2 spot, north and south, and both have ropeway. We walked around north erea and it was very beutiful, lots of pine tree and pathway of bicycles and sandy beach. I liked it very much.

And 2 day trip was over.
Tango peninsula was very attractive places like ise-shima or makino(shiga-pref.), calm sea, not so crowded like Kyoto, reserved nature and good highway (highway fee is about 2000 yen one way and about 3 hours from hirakata-city by car) so maybe we'll go there in near future.
