How shall we spend the comming holidays?

Golden Week – a series of holidays from the end of April to the beginning of May in Japan.
Recently the government has made a unusual announce, that people “should ” enjoy holidays, despite of the enormous tragedy in our country.
It said that people should spend money on travels, shopping, etc., to raise up the economy.
Is that right? I don’t feel inclined to have such a fun…Indeed I usually do not like to go into a crowd.
Anyway my husband is still on the plain to return, he will be at home at least in the afternoon, so we would spend today, Saturday, at home.



A circle with shadow at the lower part, why does it seem like a protrusion?
The professor explained that people assume the light usually comes from above.

“If there are dwellers under the ground, living without the light, they would not have such illusion at a circle painted in graduation.” he said.
“There are some people who sees the reverse illusion, that is, to whom one with darker side at the upper part seems like protrusion. It is said, though not yet evidenced, those people often stay up late at night.”

Storm in the US

I feel so sad that in the US a big storm has brought disaster. Among the people who were killed, who lost their family, house or belongings, there must be more than a few, who prayed and made donation for us.
I pray for them and I want to help them in return, but how?
I wish there would be a simple, reliable and permanent entrance to donate for each other. For example, now the japanese site of Tunes carries such system only for the Japenese Red Cross. I wish one could select countries to donate. There are many countries waiting for help.


In another day in the lecture Mechatronics we discussed about an illusion.
We looked at a famous example of it, where a circle, which is painted in white- black gradation, would seem be a protrusion from one side and a hole from another.

“Why does it seem like that?”

was the professor’s question.

A student answered, “Because there is a shadow. When the shadowy area is set at the bottom, we see a protrusion, and vice versa.”

“Good, but why do you see a protrusion when the shadowy area is at the bottom?”

Many professor ask the students repeatedly “why?”. They wish the young people to think and explain more “why?”.

Robots in the future

In the first day of the lecture we saw some movies of robots, which are designed so elaborately to simulate human beings or animals.
Then the professor asked us to make a brief report, in 10 minutes or, under the theme “In which field do you think robots will take great roles in the future, and why?”
I thought heavily, and at last wrote like:

It’s difficult to answer in 10 minutes, for the following reason:
In the past, it was easy to answer that robots would undertake dangerous or monotonous tasks instead of man. However, the more resemble robots with human being, as it is nowadays, the more sympathy man would have with them. In the future people would not like to let robots subject to such cruel works.
So what kind of a task would be, that human being can and robots cannot do, or vice versa? I can’t figure out in so short a time.

Japanese Philosophy toward Robots

This Lecture “mechatronics” is especially pointed at robotics.
As the professor told as, in Japan there is a characteristic philosophy toward robots. This philosophy is friendship, sympathy or even love.
For example, in many factories people call their arm robots installed there one by one by different name, more likely female name.
They often explain to visitors from foreign countries, saying “Today this Naomi and this Yuka are a little nervous”, which make the visitors feel peculiar.

Robot and Human Being

The third lecture, ordered by the time table, which I take is named “Mechatronics.”
The professor, who gives this lecture, had declared at first, this lecture requires not equations or calculations, but ideas and contemplation. in order to make systematic ways of thought.
There were three lessons under the theme of “Robot and Human Being.”
