Math

We let √-1 = i. This number is never exist in this world, we call it "an imaginary numer"(虚数). We call the numbers equal the real numbers (実数) plus the imaginary numbers the complex numbers (複素数). But, they should exist in another world where we can never imagin.

For example, have a look at this graph.

 

Where are the solutions? The imaginary axis should be somewhere, then y=f(x) and them meet somewhere we can never imagin. I think there is a ghost world.

 

π = C/d  (C:the circumference of a circle, d:a diameter)

 

e =  lim  (1+x)^1/x

      x→0

 

e^iπ + 1 = 0

 

This is the most beautiful formula in math.

This rules real world and fantastic world.

My favorite season

I like spring and autumn. Because the temperature is neither good nor bad. In fact, I like fashion. In spring or autumn, I can wear in various combinations.

In summer, I don't want to wear many layers of clothes, so I wear only a T-shirt. I don't like this style. In winter, I wear a coat. Outer is really expensive, so I don't have many. So I can't wear many layers of clothes.

In spring or autumn, because of the temperature is proper, I can wear many variation of clothes. T-shirts, shirts, parkas, jacket, and so on! I really enjoy fashion!

My Favorite Season

 Hello. This is Chieko.
 Today, I'm going to tell you about my favorite season.

 My favorite season is.....winter! Why? In winter, snow falls in Aomori. I like the view of outside covered with white snow. Everything turns into white and is shining in the sunlight. It is really beautiful so I feel relaxed and delighted.

　Also, in winter, I used to ski when I was an elementary school student. I have not skied for long time, but I know it is very fun to skiing. So I want to go skiing before long whether I can ski well or not. Maybe I will fall down soon.

 Lastly, this is the most important point. In January, my birthday comes!! So every year, I'm looking forward to becoming winter!

My favorite season

  Hello, this is Misaki.

  My favorite season is the beginning of summer. Actually, I didn't like this season before I came to Hirosaki. In Shizuoka, I can't concentrate because of my running nose. Yes, I am a hay fever sufferer. I love masks. In Hirosaki, however, I wasn't embarrassed with it. Moreover, I enjoyed seeing cherry-blossoms at Hirosakijo-catsle. It was amazing that cherry blossoms are blooming in the end of April.

  I also enjoyed walking along Dotemachi shopping street. My hometown has shopping streets, too, but they are more rural, so I like Hirosaki's better.

  And I want to stay at home in winter!! I'm also not good at walking on the snowy roads. So I like the beginning of summer in Hirosaki.
