I believe that the education is only the possible solution to make the world better. Would you like to join me? (In English)

This is a English translation of the last post.

Hi onigiri people,

How are you? Not seen for a long time.

I am still thinking about how I can help the Tsunami victims in  Tohoku. Although for most of the people, this is an old story. If so, you can skip the rest of my letter. You might have found a new challenging mission.

If you still care, Welcome. I finally got an idea.

I read an article about Tsunami victim children who have a problem to catch up the class in their school. I cannot stop thinking how can I help them.

I believe that the education is only the hope to solve real long term problems. But how can I help? A few months ago, I found the people who have the similar idea and they have implemented the system to help. It's free, but they need voluntary help.

It's called Kahn academy: "Khan Academy is an organization on a mission. We're a not-for-profit with the goal of changing education for the better by providing a free world-class education for anyone anywhere." I found this web page is fantastic. I take some biology and mathematics courses on this site. Unfortunately, it is only in English. But, we can voluntarily translate the site.

The number of uses of this site is more than millions. Isn't it great if Japanese or German children can also use it? For me it is just sad if children can not use the system because of just the language.

This work is steady, not a one time party. But this has an long-term impact to the world. I only work 30 minutes a day. Though I continue every day. If some of you join, the goal will be nearer.

The founder, Salman Kahn's talk. Introduced by Bill Gates.

Here is how to join the translation (Japanese, German, ...).
  1. Visit https://crowdin.net/join and sign up for a Crowdin account.
  2. Under "Edit Profile" select your "Assistance Languages."
  3. Visit https://crowdin.net/project/khanacademy to select a language.
  4. Click the green "translate" button on the next page.
  5. Start translating!

I am so happy if you just think about the possibility of changing the world to be better.

Thanks a lot.

Why parallelogram area is |ad-bc|?

Here is my question. The area of parallelogram is the difference of these two rectangles (red rectangle - blue rectangle). This is not intuitive for me. If you also think it is not so intuitive, you might interested in my slides. I try to explain this for hight school students. Slides:  A bit intuitive (for me) explanation of area of parallelogram  (to my site, external link) .

Geometric Multiplicity: eignvectors (2)

If eigenvectors of a matrix A are independent, it is a happy property. Because the matrix A can be diagonalized with a matrix S that column vectors are eigenvectors of A . For example, Why this is a happy property of A? Because I can find A's power easily. A^{10} is not a big deal. Because Λ is a diagonal matrix and power of a diagonal matrix is quite simple. A^{10} = SΛ^{10} S^{-1} Then, why if I want to compute power of A ? That is the same reason to find eigenvectors. Eigenvectors are a basis of a matrix. A matrix can be represented by a single scalar. I repeat this again. This is the happy point, a matrix becomes a scalar. What can be simpler than a scalar value. But, this is only possible when the matrix S's columns are independent. Because S^{-1} must be exist. Now I come back to my first question. Is the λ's multiplicity related with the number of eigenvectors? This time I found this has the name. Geometric multiplicity (GM): the number of in...

Tezuka Osamu's Black Jack, "Shrinking"

I like several novel authors. My first favorite author is probably Teduka, Osamu. I still love him. The list grows by adding Hoshi, Shinichi, Agatha Christie, Hermann Hesse, and so forth. My first favorite article of Tezuka was Atom as most of the (boy's) Tezuka fans did. But my favorite is Black Jack. I try to summarize one story, it is still quite vivid in my memory. I first read this story when I was 13 - 15 years old. I re-read it at least several times since Black Jack is composed of many short episodes. The title should be "ちぢむ (SHRINKING)" or it might be "縮む(Shrinking)". (It is not so convenient to translate this to English, since English does not have a system to say the exact same word in several ways. So I just simulate it with capital letters.) Black Jack is a genius surgeon, but he does not have the license. In short, his medical activity is illegal. His skill is top level in the world, but, the fee is also out-of-law expensive. In the story ...
